    FIELD OF THE INVENTION
    Generally the present invention relates to acoustic panels. In particular, the present invention pertains to acoustic panel devices, systems and methods with movable elements for managing the acoustic properties of a space.
    BACKGROUND
    Today there are specific requirements for rooms and spaces. Many spaces such as auditoriums, concert halls or arenas need to serve different type of events. For 15 example, an auditorium needs to be able to provide a space for lectures suitable for a speaking acoustic setting. To be able to utilize the space to the maximum the space needs to be suitable for other type of events as well such as music concerts. The requirements for an acoustic setting for a lecture may vary much from the acoustic settings for a music concert. Even the different types of music con20 certs (classic, rock) may have very different requirements.
    Acoustic properties are also very important for restaurants, halls and other function rooms serving festivities and other type of events. The owner or holder of the space may have strict requirements for designers and architects. The spaces 25 may need to be easily modified so that the spaces may be utilized as much as possible.
    Various soft elements can provide sound absorbing effects to a space. Soft elements absorb sound waves and thus contribute with absorbing properties to the 30 space. On the other hand, flat (hard) surfaces provide reflective effects to a space as soundwaves reflect from flat surfaces. Uneven surfaces, in turn, provide diffusing effects to the sound waves.
    There are many ways to affect the acoustic properties of a space by placing dif35 ferent elements in various locations. For example, reflective surfaces may be arranged behind the space to reflect sound to an audience, whereas absorbing elements may be scattered in the space for example in the ceiling and along the sides of the space.
    20176039 prh 22 -11- 2017
    However, spaces need to be easily and quickly modified to serve different type of events. Today there are movable elements that may be added or removed from a space to change the acoustic properties in the space. The elements may for example be soft, hard or inflatable elements. However, moving elements in and out 5 from a space requires manpower and is time-consuming.
    One problem is that several acoustic elements are fixed, separate components. In other words, in order to increase the absorbing properties of the space, more soft elements have to be introduced. If reflective or diffusing properties want to be 10 added, flat or uneven elements must be brought into the space. Many acoustic elements today require fastening to the ceiling or walls which is laborious and time-consuming.
    The spaces today also have strict requirements on design. So adding or removing 15 various acoustic elements may have a negative effect on the original design.
    Therefore, there exists a need to be able to easily change the acoustic settings in a room/space without affecting the original design of the space.
    SUMMARY OF THE INVENTION
    The objective is to at least alleviate the problems described hereinabove not satisfactorily solved by the known arrangements, and to provide a feasible solution for acoustic management of a space. One objective is to provide a device that al25 lows three different acoustic modes, an absorbing mode, a reflecting mode and a diffusing mode so that a user may independently manage the acoustics of a space by adjusting the device between the different modes. Another objective is to provide a device that allows managing the acoustic properties of a space without affecting the original design of the space.

    DETAILED DESCRIPTION OF THE EMBODIMENTS
    Referring to figures 1-3, the acoustic panel device 100 comprises a front panel 102 comprising six elongated apertures 104. The front panel may comprise any number of apertures such as two, three or eight. The apertures may also differ in shape and/or size depending on each embodiment. For example, the apertures 30 may be elongated, circular and/or squares.
    The acoustic panel device 100 comprises a back plate 106 comprising six elongated acoustic elements 108 extending from the back plate. The acoustic elements 108 may vary in shape and/or size depending on each embodiment. The 35 acoustic elements are preferably essentially the same shape and size as the apertures 104 so that the acoustic elements may move through the apertures, but may also form a flat surface together with the front panel when the acoustic elements are on the same level with the front panel.
    20176039 prh 22 -11- 2017
    Preferably, the acoustic elements 108 extend from the back plate 106 so that the acoustic elements are movable behind the front panel 102 so that the apertures 104 open, and also so that the acoustic elements extend through the front panel 5 102 when the back plate 106 is moved in the front position. Preferably, the acoustic elements 108 extend 5-50 cm from the back plate.
    In figures 1 and 4, the back plate 106 is in its rear position so that the acoustic elements 108 are behind the front panel. When the back plate is in the rear posi10 tion, the acoustic panel device 100 is in an absorber mode. The apertures are open as the acoustic elements 108 are behind the front panel 102. Sound waves may enter the device. The back plate may comprise a layer of sound absorbing material 110 such as acoustic wool, acoustic (peat) fiber, acoustic foam and/or PE-foam to enhance sound absorption.
    In figures 2 and 5, the back plate 106 is in a middle position so that the acoustic elements 108 are on the same level with the front panel 102, forming a flat surface with the front panel. When the back plate is in the middle position, the acoustic panel device 100 is in a reflector mode. Sound waves may reflect from 20 the flat surface.
    In figures 3 and 6, the back plate 106 is in a front position so that the acoustic elements 108 are in front of the front panel 102. In the front position the acoustic elements 108 extend through the apertures 104.
    Preferably the back plate 106 is movable in relation to the front panel 102. Alternatively, in some embodiments, the device may be configured so that the front panel 102 is movable in relation to the back plate 106.
    Referring to figures 4-6, the acoustic panel device 100 comprises a casing 112 that surrounds the back plate 106 creating a closed space for the device so that sound waves may enter the device when the back plate is in the rear position and the apertures are open.
    Preferably, an electric motor 114 is arranged behind the back plate 106 so that the back plate is movable with the motor. Alternatively, hydraulic and/or pneumatic means may be arranged to move the back plate. The device may comprise an interface such as a control panel or a simple button for controlling the move
    20176039 prh 22 -11- 2017 ment of the back plate. Alternatively, the back plate is manually movable, comprising a manually operated lever or handle, for example.
    The front panel 102, back plate 106, acoustic elements 108 and/or casing 112 are 5 preferably made of wood. Alternatively, the parts are made of some other hard and/or durable material such as plastic, wood based board (e.g. chip board, MDF), plastic composites, aluminum, steel and/or hard cardboard. Sound/acoustic properties can be affected with different material selections. Acoustic properties may be affected by selecting different wood types as well.
    Referring to figure 7, according to a system 201 of the present invention the acoustic panel device 200 is controlled wirelessly with electronic means 220 such as a smartphone, tablet computer or laptop. Alternatively, the system comprises other wireless electronic means for controlling the acoustic panel device such as 15 radio remote control with a dedicated remote control device. Preferably, the electronic means are configured to control the electric motor that moves the back plate. Alternatively, hydraulic and/or pneumatic means are controlled with the electronic means.
    Figure 8 is a flow diagram of an embodiment of a method in accordance with the present invention.
    At method start-up 302, preparatory actions may take place. This may include setting up an acoustic panel device, and/or a system comprising means for con25 trolling the acoustic panel device.
    At 304, soundwaves are absorbed. The step may comprise moving a back plate and/or acoustic elements in a rear position to open apertures for soundwaves to enter an acoustic panel device.
    At 306, soundwaves are reflected. The step may include moving a back plate and/or acoustic elements in a middle position so that a flat surface is formed.
    At 308, soundwaves are diffused. The step may include moving a back plate 35 and/or acoustic elements in a front position so that an uneven surface is formed.
    As is understood, the three method steps or modes do not always take place in the presented order. The dotted lines in figure 8 represent that embodiments of the method includes steps in varying order.
    At 310, the method execution is ended.
    Consequently, a skilled person may on the basis of this disclosure and general knowledge apply the provided teachings in order to implement the scope of the present invention as defined by the appended claims in each particular use case 10 with necessary modifications, deletions, and additions.
