    Description loudspeaker system
    The invention relates to a loudspeaker system with an amplifier element and at least one membrane for converting electrical energy into sound waves, as well as connections for connection to at least one audio signal generator.
    Loudspeaker systems or, according to another common name, sound transducers are used to convert electrical energy into sound waves. These membranes are usually put into mechanical vibrations.
    Loudspeakers are used in speakers, radios, televisions, radio receivers, hand-held radios, test receivers, mobile phones and MP3 players.
    Especially for mobile devices is limited by the required electrical energy of the use of speakers in terms of their performance and the duration of operation, since the accumulators or batteries used in these devices have only a limited charge capacity.
    The invention has for its object to expand the application of speaker systems, especially in mobile devices.
    This object is achieved in that in a speaker system of the type mentioned, the at least one membrane of the speaker system is at least partially covered with an energy converter element, which is connected to the amplifier element in such a way that the power supply of the amplifier element is performed by the energy converter element.

    According to the invention, the surface of the membrane of a loudspeaker is used to generate energy. This energy is used to operate the loudspeaker, resulting in a self-powered loudspeaker system. This system can be used by connecting to an audio signal transmitter such as a radio, portable multimedia player, mobile phone or MP3 player to extend the acoustic performance of these devices and to conserve the electrical storage capacity of this device. Moreover, it is also conceivable that the energy stored in the loudspeaker system according to the invention is "misappropriated". for the supply of other electrical consumers such as to charge the listed devices.
    The energy production according to the invention is particularly advantageously possible with the aid of flexible solar cells.
    Of the known solar cell technologies are particularly peculiar to thin-film cells, especially based on amorphous silicon. However, it would also be conceivable to use organic solar cells.
    Essential here is the possibility of creating flexible structures with the technology used, which does not change the acoustic properties of a loudspeaker membrane coated therewith too much.
    Also particularly advantageous is the use of triple-junction technology, which uses the blue, green and red portions of sunlight in different layers of the solar cell. As a result, a higher efficiency is achieved with low solar radiation and diffused light. Even with partial shading power generation is still possible. * i · l * * ·

    When integrating the loudspeaker system according to the invention into a pocket, a particularly user-friendly solution is created.
    In this case, the speaker system can be integrated in an advantageous manner in a removable part of the bag.
    The invention will be explained in more detail with reference to figures.
    They show by way of example:
    1 shows a loudspeaker system according to the invention
    Fig. 2 shows the structure of an exemplary first membrane and
    Fig. 3 shows the structure of an exemplary second membrane.
    1 shows a loudspeaker system according to the invention with an amplifier element 1 and a membrane 2 for converting electrical energy into sound waves, as well as connections 3 for connection to at least one audio signal transmitter such as a radio, portable multimedia player, mobile telephone or MP3 player , The membrane 2 of the speaker system is covered with an energy conversion element 4 in the form of a thin-film solar cell module based on triple-junction technology.
    This technology is characterized by particularly high efficiency with low solar radiation and diffuse light. Since power generation is still possible even with partial shading, such solar cells can be provided with a decoratively designed surface such as, for example, a patterned foil.
    In the application example, 6 solar cells with a total area of 0.04 m2 are connected to form a module, in each case three cells are connected in series and two rows in parallel. This will be in low light conditions

    Output voltage of 6 volts and an output current of 500mA so achieved a power of 3 watts.
    Thus, a conventional amplifier element 1 can be supplied with electrical energy. Since commercially available amplifier elements require a comparatively stable DC voltage of typically 5 volts for their supply, a voltage stabilizer 8 is inserted between the energy converter element 4 and the amplifier element 1, by means of which the voltage supply of the amplifier element 1 is kept in the required tolerance range.
    The amplifier element 1 controls a sound transducer 9, which, as shown in Figures 2 and 3, comprises a membrane 2, which may have different shapes.
    As shown in Fig. 2, the membrane 2 may be formed for example as a straight surface, or as a cone.
    The common structure of membrane 2 and
    Energy conversion element 4 comprises 3 layers that are laminated in a sandwich process. On a carrier film 5, which may be for example made of nylon, PET, TPU or a similar material from the elastic properties, tripple junction polymer photovoltaic cells 6 (thin-film cells) are applied. Above it is a protective layer 7 made of a UV-transparent film such as PET or TFE. Thin-film cells 6 are usually constructed of amorphous silicon, which enables durable products. Conceivable further materials are microcrystalline silicon, gallium arsenide, cadmium telluride or copper indium (gallium) sulfur selenium compounds, the so-called CIGS solar cell or CIS cells. 5 • · «*« • ·

    By using the so-called triple-junction technology, in which the thin-film cells 6 have three active semiconductor layers, the efficiency of conventional thin-film cells can be significantly increased. In addition, the age-related decline in the efficiency of solar cells (degradation) is also reduced.
    According to the invention, the electrical energy produced by the energy conversion element 4 can also be stored by means of accumulators, and / or used to supply the audio signal transmitter or, if appropriate, other electrical consumers, such as, for example, lighting elements.
    The invention can be used particularly advantageously with accessories such as bags, but the application is not limited thereto. Thus, it is conceivable, for example, to create large sound transducers, for example, as acoustic billboards.
    Furthermore, the invention is not limited to the use of solar cells, it is also conceivable in principle to use other energy conversion processes such as on a thermal basis.
