In the following description and/or claims, when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present; when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present, and other words used to describe the relationship between the elements or layers should be interpreted in the same manner. For ease of understanding, like elements in the following embodiments are illustrated with like reference numerals.

Fig. 1 is a structural diagram of an electret electrostatic planar horn according to a first embodiment of the present invention. As shown, the electret electrostatic planar horn 1 includes a first speaker module 11, a second speaker module 12, and a barrier layer 13.

The first speaker module 11 includes a first conductive layer 111, a first polymer material layer 112, a first adhesive layer 113, a first conductive material layer 114, a first adhesive layer 115, and a first sound-emitting material layer 116, which are sequentially adhered and stacked. The combination of the first conductive layer 111 and the first polymer material layer 112 is processed by an electret process to charge the first conductive layer 111.

The second speaker module 12 includes a second conductive layer 121, a second polymer material layer 122, a second glue layer 123 and a second conductive material layer 124, which are sequentially laminated and stacked. The combination of the second conductive layer 121 and the second polymer material layer 122 is processed by an electret process to charge the second conductive layer 121. In one embodiment, the first polymer material layer 112 and the second polymer material layer 122 are made of a non-perfluorinated electret polymer material copolymerized by vinylidene fluoride monomer (VdF), the monomer copolymerized with VdF includes Hexafluoropropylene (HFP), Chlorotrifluoroethylene (CTFE), Tetrafluoroethylene (TFE), Polytetrafluoroethylene (PTFE), or any combination thereof, and the polymer copolymer containing fluorine partially as the material of the electret can satisfy the conditions of charge stability, processability, and price. The first conductive layer 111 and the second conductive layer 121 can be charged more effectively and have charge stability through the above-mentioned special material and the operation of the charging process, so as to achieve better effect. In one embodiment, the first conductive layer 111 and the second conductive layer 121 may be iron mesh, copper foil, stainless steel, or other similar materials. In one embodiment, the first adhesive layer 113 and the second adhesive layer 123 are a back adhesive, a double-sided adhesive, an ultraviolet adhesive, a resin, a glue, or other similar materials. In one embodiment, the first adhesive layer 115 can be black glue, spiral glue, or glue with similar properties. In one embodiment, the first sound-emitting material layer 116 is made of a sound-emitting material such as glass, an organic light-emitting diode (OLED) panel, or a micro light-emitting diode (LED) panel.

The barrier layer 13 is disposed between the first conductive layer 111 and the second conductive layer 121 to block the first speaker module 11 and the second speaker module 12. In one embodiment, the barrier layer 13 may be a spacer, a glue, or other similar material. The first speaker module 11 and the second speaker module 12 are symmetrically arranged; in other words, the first conductive layer 111 is symmetrical to the second conductive layer 121, and the first polymer material layer 112 is symmetrical to the second polymer material layer 122.

When the first speaker module 11 and the second speaker module 12 are driven by audio signals, vibration is generated, and fine sound is directly and finely generated. In other words, the ultrathin film has a layer of charged nanoporous polymer material: PTFE membranes, which are sensitive to any input power, produce small vibrations. The electret electrostatic flat horn 1 can reproduce an originally fine sound without the need of a conventional high voltage amplifier. The electret electrostatic planar horn 1 of the present embodiment can be applied to various electronic devices, such as a tablet computer, a notebook computer, an electronic book, an electronic photo frame, a mobile phone, a personal digital assistant, a digital camera, a television, a flat panel display, or a home theater audio-visual device.

Fig. 2 is a structural diagram of an electronic device with an electret electrostatic planar horn according to a first embodiment of the present disclosure. As shown in the figure, the electronic device E includes a frame F, an electret electrostatic planar horn 1, and a driving module D. In this embodiment, the electronic device E can be an electronic device such as a smart phone, a tablet computer, a notebook computer, a flat panel display, etc., and the frame F thereof includes the screen C. Wherein, the screen C is used as the sound-producing material layer 116 of the electret electrostatic planar speaker 1 of FIG. 1 and can be glass; in another embodiment, the outer frame F of the electronic device E can be used as the sound-generating material layer 116, which can be made of glass, organic light-emitting diode (OLED) panel, or micro light-emitting diode (LED) panel.

The driving module D can generate audio signals to drive the static charge-standing planar speaker 1. When the electret electrostatic planar speaker 1 is driven by an audio signal, the first speaker module 11 and the second speaker module 12 can vibrate, and at the same time, the screen C of the outer frame F resonates and emits a sound S, so as to achieve excellent sound effect and definition.

When applied to other electronic devices, the electret electrostatic planar horn 1 may also emit the sound S by resonating the entire outer frame F of the electronic device E, or by resonating other parts of the outer frame F of the electronic device E, such as a cover, glass, etc. Besides the smart phone, the electret electrostatic planar horn 1 can be applied to various electronic devices, such as tablet computers, notebook computers, electronic books, electronic photo frames, personal digital assistants, digital cameras, flat panel displays or home theater audio-visual equipment, and is therefore very widely used.

In addition, since the electret electrostatic planar horn 1 can generate the sound S by resonating all or part of the outer frame F of the electronic device E, the outer frame F of the electronic device E does not need a horn hole, so that the appearance of the electronic device E can be more beautiful, and the manufacturing cost can be reduced.

Furthermore, according to the embodiments of the present invention, the electret electrostatic planar horn has a simple design, so that the desired effect can be achieved without increasing the cost greatly, and the commercial value is very high. And are not readily appreciated by those skilled in the art.
