    DESCRIPTION OF EMBODIMENTS
    [First embodiment]
    [0025] An example of a wristwatch strap according to a first embodiment will be described with reference to Figures 1 to 4. Figure 1 is a view illustrating an example of a watch according to the first embodiment. FIG. 2 is a view illustrating an example of a computer and of a circuit mounted on the wristwatch strap according to the first embodiment. As illustrated in Figure 1, a watch 100 comprises a wristwatch case 10, an elastic bar 20, and a wristwatch strap 30.
    The wristwatch case 10 is a case in which a mechanical movement, an hour hand, a minute hand, a seconds hand and the like are housed, and it is connected to the wristwatch strap 30 by the bar elastic 20.
    The wristwatch strap 30 includes a ticking sound sensor 301, an amplifier 302, a filter 303, an environment sensor 304, an oscillation circuit 305, a frequency divider circuit 306, a memory dead memory (ROM) 307, and a random access memory (RAM) 308, a central processor (CPU) 309 and a communication unit 310.
    [0028] The ticking sound sensor 301 is a device which detects a ticking sound generated inside the watch 100 and generates ticking sound data indicating the ticking sound. The ticking sound mentioned here is, for example, a sound generated during the operation of an escapement included in the watch 100. In other words, the ticking sound here is, for example, a sound generated when a escapement mobile and an anchor arranged inside the watch 100 come into contact with one another. The ticking sound sensor 301 is, for example, a piezoelectric element or a microphone. The ticking sound sensor 301 is in contact with the elastic bar 20 attached to the watch 100.
    The ticking sound sensor 301 detects a ticking sound by detecting a vibration transmitted by the wristwatch case 10 and the elastic bar 20 included in the watch 100. Alternatively, the ticking sound is detected by detecting a vibration transmitted by the wristwatch case 10 and the air included in the watch 100. The ticking sound sensor 301 converts the detected ticking sound into ticking sound data, which is data in analog or digital form, and outputs the data to amplifier 302. Amplifier 302 amplifies the wave amplitude of the ticking sound indicated by the ticking sound data. The filter 303 removes the noise included in the wave of the ticking sound amplified by the amplifier 302, and transmits the ticking sound data to the processor (CPU) 309.
    [0030] The environment sensor 304 detects a physical quantity indicating an environment outside the watch 100, and generates environmental data indicating the physical quantity. The environment sensor 304 is, for example, an acceleration sensor, a temperature sensor, an atmospheric pressure sensor, or a magnetic field sensor. The physical quantity indicating the external environment here is, for example, the acceleration of watch 100, temperature, atmospheric pressure, and the strength of a magnetic field around watch 100. The environment data is data associated with the ticking sound data. For example, environmental data is data indicating a physical quantity detected during the same period as the ticking sound data which is chronologically serial data.
    A change in acceleration of the watch 100 is caused depending on the manner of swinging the arm of a user wearing the watch 100, or varies when the watch 100 falls. In these cases, since gravity applies to a mainspring inserted in watch 100 changes, the operation of the mainspring may be affected, and the frequency of watch 100 and the angle of oscillation of a balance with a The sprung balance of the watch 100 may change accordingly.
    Since a change in temperature around watch 100 affects the expansion and contraction of the components that constitute the movement of watch 100 and influence the operation of the movement, the frequency of watch 100 and the angle d The oscillation of the balance with the hairspring of the watch 100 may vary.
    A change in atmospheric pressure around the watch 100 changes the density of gas existing inside the watch 100, thereby changing the intensity of the air resistance applied when the sprung balance included in watch 100 is working. Therefore, a change in atmospheric pressure around watch 100 can cause the frequency of watch 100 and the angle of oscillation of the spiral balance included in watch 100 to vary.
    Since a change in the magnetic field around the watch 100 changes the operation of the components that make up the movement of the watch 100, the frequency of the watch 100 and the angle of oscillation of the balance with the hairspring of the watch 100 may also vary. The factor which varies the magnetic field around watch 100 includes, for example, a magnet built into the opening and closing portions of a bag placed around watch 100.
    [0035] The oscillation circuit 305 generates a signal having a predetermined frequency, for example, a frequency of 32768 Hz, and transmits the signal to the frequency divider circuit 306. The frequency divider circuit 306 divides the frequency of the received signal by the oscillation circuit 305, generates a wristwatch signal as a time measurement reference, and transmits the wristwatch signal to the central processor (CPU) 309.
    Read-only memory (ROM) 307 stores a program read and executed by the CPU 309, for example, a data transmission program 3070a illustrated in Figure 3. Figure 3 is a view illustrating an example of a program transmission process executed by a CPU according to the first embodiment. As illustrated in Fig. 3, the data transmission program 3070a includes a data acquisition function 3071a, a precision data generation function 3072a, and a data transmission function 3073a.

The function Data acquisition 3071a can further acquire environment data generated using the environment sensor 304. The precision data generation function 3072a is a precision data generation function indicating the accuracy of the time. displayed on the watch 100 including at least one of the frequency of the wristwatch 100 and the oscillation angle of the spiral balance included in the wristwatch 100, based on the ticking sound data. Specifically, the precision data generation function 3072a compares the wave frequency of the ticking sound indicated by the ticking sound data with the frequency of the wristwatch signal generated by the frequency divider circuit 306. to calculate the frequency and angle of oscillation by calculating the difference between the two. Precision data is data used by another device to assess the accuracy of the time displayed by the wristwatch 100 and to notify the details and deadline of the repair and inspection based on the result of the 'Evaluation. An example of another device mentioned here is for example a smartphone or a tablet. Data transmission function 3073a is a function of transmitting precision data to another device using the communication unit 310 described later. The data transmission function 3073a can further transmit the environmental data to another device using the communication unit 310 described later.
    RAM 308 stores the ticking sound data described above, environment data, and precision data.
    [0039] The CPU 309 reads and executes the data transmission program 3070a illustrated in Fig. 3. As a result, the CPU 309 obtains the ticking sound data using the ticking sound sensor 301, the amplifier 302, and filter 303, generates precision data using precision data generation function 3072a, oscillation circuit 305, and frequency divider circuit 306, and transmits precision data to another device using the data transmission function 3073a and the communication unit 310. The CPU 309 reads and executes various programs stored in the ROM 307 to appropriately control each component of the wristwatch strap 30.
    [0040] The communication unit 310 transmits the ticking sound data to another device. The communication unit 310 may periodically transmit the ticking sound data stored in the RAM 308 to another device, or may transmit the ticking sound data to another device whenever the ticking sound data. ticking are stored in RAM 308.
    The communication unit 310 transmits the precision data generated by the CPU 309 to another device. Communication unit 310 may periodically transmit the precision data stored in RAM 308 to another device, or may transmit the precision data to another device whenever the precision data is stored in RAM 308.
    [0042] The communication unit 310 can further transmit the environmental data generated by the CPU 309 to another device. The communication unit 310 may periodically transmit the environmental data stored in the RAM 308 to another device, or may transmit the environmental data to another device whenever the environmental data is stored in the RAM 308. .
    FIG. 4 is a view illustrating an example of a structure of the wristwatch strap according to the first embodiment. The wristwatch strap 30 is a metal band and includes a buckle 311, a plurality of segments 312, and a plurality of cables 313.
    The buckle 311 is, for example, a metal clip adapted to vary the length of the wristwatch strap 30 when the user attaches the watch 100 to his arm, and detaches it therefrom, and accommodates a module including the oscillation circuit 305, the frequency divider circuit 306, the ROM 307, the RAM 308, the CPU 309, and the communication unit 310 shown in Fig. 2, for example.
    The segment 312 is coupled to another segment 312 or to the loop 311 to form a metal strip, and a housing 3121 disposed inside the segment 312 houses a module including the ticking sound sensor 301, the amplifier 302, and filter 303 shown in Figure 2, for example.
    The cable 313 connects a module including the oscillation circuit 305, the frequency divider circuit 306, the ROM 307, the RAM 308, the CPU 309, and the communication unit 310 housed in the loop 311 and a module including the ticking sound sensor 301, amplifier 302, and filter 303 housed in segment 312.
    The wristwatch strap 30 may include a flexible printed circuit in place of the cable 313.

    A bracelet 30 for a wristwatch according to the first embodiment has been described above. The wristwatch strap 100 generates ticking sound data indicating the ticking sound generated inside the watch 100, generates precision data indicating the accuracy of the time displayed by the watch 100 based on the ticking sound data, and transmits the data to another device. Therefore, the wristwatch bracelet 30 can collect data on the displayed time accuracy for any watch and provide the data to another device.
    [0049] The wristwatch strap 30 100 may further include the environment sensor 304 which detects a physical quantity indicative of an environment outside the wristwatch 100 and generates environmental data indicating the physical quantity. and can further transmit the environmental data to another device. Therefore, the wristwatch strap 100 can provide another device with the displayed time accuracy of any wristwatch in association with the environment in which the watch 100 is used.
    [0050] The ticking sound sensor 301 can be in contact with the elastic bar 20 attached to the watch 100 and can detect the ticking sound by detecting a vibration transmitted by the wristwatch case 10 and the elastic bar 20 included in the watch 100. Thus, the bracelet 30 of the wristwatch 100 can prevent the noise from being included in the wave of the ticking sound indicated by the ticking sound data by detecting the vibration generated at. the outside of the case 10 of the wristwatch.
    [0051] The ticking sound sensor 301 can detect the ticking sound by detecting the vibration transmitted by the wristwatch case 10 and the air included in the wristwatch 100. Therefore, the wristwatch strap 30 100 does not necessarily need to bring the ticking sound sensor 301 into contact with the elastic bar 20, and therefore the manufacturing process is simplified and the manufacturing cost is reduced.
    [0052] The ticking sound sensor 301 may be a piezoelectric element. Therefore, the wristwatch strap 30 can accurately detect the vibration of the elastic bar 20 and generate ticking sound data indicating the precise wave of the ticking sound.
    [0053] The ticking sound sensor 301 may be a microphone. Therefore, the wristwatch strap 30 detects the vibration transmitted by the elastic bar 20 by a relatively inexpensive device, and therefore the manufacturing cost is reduced.

The acquisition function data station 3071b can further acquire environment data generated using the environment sensor 304. The data transmission function 3072b can use the communication unit 310 to transmit the ticking sound data to another. device.
    [0057] The communication unit 310 transmits the ticking sound data generated by the CPU 309 to another device. The communication unit 310 may periodically transmit the ticking sound data stored in the RAM 308 to another device, or may transmit the ticking sound data to another device whenever the ticking sound data. ticking are stored in RAM 308.
    [0058] The wristwatch strap according to the second embodiment has been described above. The wristwatch strap according to the second embodiment generates ticking sound data indicating a ticking sound generated inside the wristwatch 100 and transmits the ticking sound data to another. device. That is, unlike the wristwatch strap 30 according to the first embodiment, since the wristwatch strap 30 according to the second embodiment does not generate precision data, and transmits the data to a other device, it is not necessary to include hardware or software to generate precision data. Therefore, the wristwatch strap according to the second embodiment can be realized with reduced manufacturing costs and compact size in a simple configuration, in addition to the beneficial effects of the wristwatch strap 30 according to the first embodiment.
    In the first embodiment and the second embodiment, as illustrated in Figure 4, the case where the metal wristwatch strap 30 is connected to the wristwatch case 10 has been described by way of example, but the present invention is not limited to such configurations. For example, the wristwatch case 100 can be connected to the wristwatch strap as shown in Figure 6 or 7.

    [0063] The 311Y loop houses, for example, a module including the oscillation circuit 305, the frequency divider circuit 306, the ROM 307, the RAM 308, and the CPU 309 illustrated in FIG. 2. The strap 312Y forms a leather strap by being connected to the 311X buckle, and a 3121Y case fitted inside the 312Y strap houses a module including the ticking sound sensor 301, the amplifier 302, the filter 3 and the unit communication 310 illustrated in Figure 2, for example. The 312Y webbing can be made of urethane or made of silicon instead of leather.
