Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description.
As depicted in figs. 1 and 2, electroacoustic transducer involving vibrations system, magnetic circuit system, and accommodate the fixedly housing 1 of vibrational system and magnetic circuit system.The vibrating diaphragm system comprises vibrating diaphragm 21 and is incorporated into the voice coil loudspeaker voice coil 22 of vibrating diaphragm 21 downsides; Magnetic circuit system comprises washer 31, magnet 32 and the basin frame 33 of successively combination; Magnetic circuit system forms the magnetic gap of accommodating voice coil loudspeaker voice coil 22.
Vibrating diaphragm 21 comprises the ring section 212 at ball top 211 and the edge at center, as shown in Figure 2, present embodiment vibrating diaphragm 21 is the racetrack structure, comprises two straight lines that are oppositely arranged and two arc-shaped sides that are oppositely arranged, and the ring section 212 of vibrating diaphragm 21 corresponding two arc-shaped sides is provided with the accordion decorative pattern.The accordion decorative pattern can increase the intensity of vibrating diaphragm, prevents vibrating diaphragm 21 distortion.
In addition, the utility model is provided with damping piece 4 in the ring section 212 corresponding to the decorative pattern part, and damping piece 4 is elastomer structure, and damping piece 4 extends along the line style corresponding with the arc-shaped side of racetrack vibrating diaphragm 21 in ring section 212, is the arc shaped structure.The utility model damping piece is arranged at vibrating diaphragm 21 away from a side of voice coil loudspeaker voice coil 22, the technique that can simplify the operation, and the damping that produces is good.As shown in Figure 2, the decorative pattern on the damping piece 4 corresponding voice coil loudspeaker voice coils 21 arranges and forms two relative arc line type structures.In the present embodiment, damping piece 4 adopts flexible colloid, after vibrating diaphragm 21 moulding, gets final product along gluing on the position of corresponding two arc-shaped sides in the vibrating diaphragm 21 ring sections 212, realizes easily on the technique.
The structure of damping piece 4 is set in the ring section 212 corresponding with the decorative pattern part on this vibrating diaphragm 21, can increases the intensity of vibrating diaphragm 21, and can increase the damping coefficient of vibrating diaphragm 21, thereby improve the acoustical behavior of product.
Fig. 3 is the structural representation of the utility model electroacoustic transducer vibrating diaphragm another embodiment, as shown in the figure, present embodiment damping piece 4 ' is racetrack, and is corresponding with the shape of vibrating diaphragm 21, and present embodiment also is provided with damping piece 4 ' in the ring section 212 corresponding with two straight lines.In this programme, the position on line correspondence limit can arrange decorative pattern or the enforcement that does not all affect this programme is not set in the vibrating diaphragm 21 ring sections 212.This structure that damping piece 4 ' all is set in whole ring section 212 can increase the intensity of vibrating diaphragm 21 equally, increases the damping coefficient of vibrating diaphragm 21, improves the acoustical behavior of product.
Under above-mentioned instruction of the present utility model; those skilled in the art can carry out on the basis of above-described embodiment other improvement and distortion; and these improvement and distortion; all drop in the protection range of the present utility model; those skilled in the art should be understood that; above-mentioned specific descriptions are just better explained the purpose of this utility model, and protection range of the present utility model is limited by claim and equivalent thereof.
