摘要： The present invention is directed to a sound reproduction device which includes an LCD (20), which is an exemplary front panel, a case (22), and an electromechanical acoustic transducer (23). TheLCD (20) isoperabletoperformapredeterminedoperation in response to an electrical signal applied thereto. A space (24) for sound emission is formed between the case (22) and the LCD (20). The electromechanical acoustic transducer (23) is connected to the case (22), and emits sound to the space (24). If the electromechanical acoustic transducer (23) emits the sound to the space (24), energy of the emitted sound causes the LCD (20) to vibrate and thereby to externally output the sound.

摘要： Disclosed are a silica gel diaphragm, a receiver module, and a method for processing a silica gel diaphragm. Two metal pieces are integrally injection-molded on the silica gel diaphragm, and symmetrically embedded into the silica gel diaphragm, and either end of each of the metal pieces is provided with a first soldering portion and a second soldering portion; each of the first soldering portions is embedded into the planar portion of the silica gel diaphragm that is closer to the folded ring portion, and is used for soldering a winding tap of a voice coil on an inner side of the voice coil; each of the second soldering portions protrudes from or is embedded into the fixing portion of the silica gel diaphragm, and is used for soldering a bonding pad on a housing; and middle portions connecting the first soldering portions and the second soldering portions are embedded into the silica gel diaphragm to form an electrically conductive path. Via the technical solution wherein the voice coil lead wires are replaced by the two metal pieces of the silica gel diaphragm, the present disclosure completely solves the problem of the poor audition caused by the collision of the voice coil lead wires, and the metal pieces injection-molded in the silica gel diaphragm also prevent the risk of the breakage of the voice coil lead wires, thereby increasing the product stability.

摘要： An electrostatic loudspeaker comprises a membrane structure and an electrode structure. The membrane structure comprises a central membrane portion and a circumferential membrane portion. The electrode structure is configured to electrostatically interact with the membrane structure for causing a movement of the membrane structure along an axis of movement. The electrode structure comprises a circumferential electrode portion and an opening, the circumferential electrode portion being substantially aligned to the circumferential membrane portion and the opening being substantially aligned to the central membrane portion with respect to a direction parallel to the axis of movement. In an end position of the movement of the membrane structure, the central membrane portion is configured to extend at least partially through the opening. A method for operating an electrostatic loudspeaker and a method for manufacturing an electrostatic loudspeaker are also described.
