In order to understand the present invention, detailed steps will be set forth in the following description and its features = reduction. The implementation of the present invention is limited to those skilled in the art: , , , and . The other aspects of the composition or steps are not described in the details, and the new cost is not to be avoided. The preferred replenishment of the present invention will be described in detail below. In addition to these detailed descriptions, the present invention can be widely applied to other types of additions, and the nucleus type of fine material is limited in scope. *Reference According to the first i, the first implementation of the present invention - an ultra-thin electroacoustic transducer' includes a magnetic body consisting of a circular basin frame m, a lion magnet 1〇2 and a ring-shaped washer 1〇3 in sequence. The road device, the basin frame 1〇1 has a flat bottom bottom for placing the magnet 102 and the washer 1〇3, and the convex portion extending inside the magnet 1〇2 and the washer 1〇3 and facing the magnet to the side of the washer 103 The upper portion 1〇1a is provided with a basin recess 110b facing the bottom of the basin frame 101 in the convex portion ι〇ι& the shape of the basin frame recess 101b is a trapezoidal depression having a large upper and lower shape, so that the magnet 102 and the The slats 103 and the bosses 10 are formed to form a magnetic gap of the ring; a plastic casing 1 〇 4 is included to fix the magnetic circuit device together; and a diaphragm 105 is included, and the diaphragm 105 includes an edge portion 105a and a central portion. L〇5b, the voice coil 1〇6 is installed below the joint position i〇5c of the edge portion i〇5a and the middle portion 105b, and the voice coil 106 is in the annular magnetic gap, so that the diaphragm 105 and the voice coil 1〇6 form an ultra-thin a vibrating device of the electroacoustic transducer; the edge of the edge portion of the diaphragm is preliminarily dried at the edge of the washer 103; L〇5b provided towards the middle recess M347779 Penjia notch 101b and the recess 101b corresponding diaphragm basin frame recess. This ultra-thin electroacoustic conversion n, the magnetic circuit structure of the mining, the central concave of the basin frame and the central position of the diaphragm at the corresponding position also adopts a recessed design, which can greatly reduce the product height without sacrificing the volume of the magnet. The size is greatly reduced, the power of the product is increased, and the Fg (maximum __ rate) can be lowered and the high frequency is expanded. Products with the same structure use less parts, and the installation of each part is not required. Additional positioning tooling is now automated production, fine (four) pre-combined # reloading the electroacoustic converter, It also makes the assembly of the electroacoustic transducer easier. Referring to the second figure, a schematic structural view of a second embodiment of the present invention is shown. The first figure is a schematic top view of a magnetic circuit portion of the second embodiment of the present invention. The present embodiment and the first embodiment mainly have the following differences: 超. The shape of the ultra-thin electroacoustic transducer is elongated 'the corresponding magnetic circuit structure is also elongated, and the two elongated magnets iQ2, (4) 1〇3 is distributed on the side of the wire 101 _; 2, the inner part of the wall of the 1 〇H wall is removed, and the center forms a hole, so that the basin frame 1〇1 is divided into two parts. L _ long strips; 3 · the position on the money and the magnetic _ corresponding to the plurality of symmetrically distributed small holes 1 〇 le. The design of each structure conforms to the structure design of electroacoustic transducers with more and more long strip shapes and long magnetic circuit structures; the holes and small hole wrists formed in the middle of the basin frame can be used as the rear sound holes for sounding and The internal and external air pressure balance of the electroacoustic transducer is maintained, and can be used for the heat generated by the long-term operation of the acoustic generator, and the position and shape of the small holes are symmetrically distributed, so that the magnetic lines of the Wei (4) magnetic line are symmetrical. Referring to the fourth figure, the structural schematic diagram of the third embodiment of the present invention has the following differences between the embodiment of the M347779 and the first embodiment: 1. The portion of the basin recess 101b of the basin m is partially cut off. Forming a hole moid, the outer side of the hole i〇id is provided with a damping 108; 2. The pre-mosquito at the edge of the diaphragm 105 is connected to a copper ring 1〇7, and is fixed on the washer 103 by the copper soil 107; 3. the edge of the diaphragm The joint 105c of the part 1〇5a and the middle lion adopts a smooth design. The design of this structure, the hole 1〇ld formed in the middle of the basin frame can be used as the rear sound hole for sound distribution and county electric sound conversion such as external air pressure balance, and can be used to dissipate the heat generated by the long-term work of the turtle recovery converter, the hole The outer side of the damping can adjust the performance of the product, adjust the distortion by adjusting the thickness of the diaphragm, etc. The edge of the diaphragm is fixedly connected by a copper ring, which can improve the height of the edge of the diaphragm and further reduce the impact of the edge of the diaphragm on the magnetic circuit device. Possibility, the smooth design of the joint between the edge of the diaphragm and the middle part can make the voice ring and the dead side of the diaphragm more parallel, and the dead area is larger. The smooth design of the whole part of the diaphragm also makes the diaphragm production more easily. Referring to the fifth figure, a schematic structural view of the vibrating portion of the electroacoustic transducer according to the fourth embodiment of the present invention, the main difference between the first embodiment and the first embodiment is that a multi-layer composite film is disposed on the depressed portion 105b in the middle portion of the diaphragm. L〇5d. The increase of the composite film l〇5d can make the vibration frequency of each part of the diaphragm different, and the electroacoustic transducer F〇 (the lowest resonance frequency) is further reduced, and the sound quality is further improved. The composite film is generally made of a layer of aluminum foil or plastic material. The material can be consistent with the diaphragm material, or it can be inconsistent. It is mainly adjusted according to different sound quality requirements. At the same time, the composite film can be placed on the top or bottom of the diaphragm or on both sides. One or more layers may be provided; generally, when the diaphragm 11 M347779 film is formed, the composite film is integrally disposed on the diaphragm. Compared with the existing ultra-thin electroacoustic converter design, this new model can greatly reduce product size, increase product power, and improve product performance, while reducing production costs and facilitating automated production. Obviously, the present invention may have many modifications and differences as described in the above embodiments. It is to be understood that the scope of the claims is to be understood in addition to the above detailed description. The present invention can be widely practiced in other embodiments. The preferred embodiment of the above-mentioned new type of forest is the same as that of the following, and all other equivalent changes or modifications made without departing from the spirit of the present invention should be included in the scope of the following application. 12 M347779 [Simplified description of the drawings] The first drawing is a schematic structural view of the first embodiment of the present invention; the second drawing is a schematic structural view of the second embodiment of the present invention; and the third drawing is the magnetic structure of the second embodiment of the present invention.
