Embodiment

[0029] Such as Figure 1-Figure 2 Commonly shown, the long and narrow moving coil sound generator of this embodiment includes two drive units, that is, two voice coil units 4 and two corresponding magnetic circuit units, wherein the voice coil unit 4 includes a voice coil 41 and a The skeleton 42 supporting the voice coil, the voice coil 41 is connected with the vibrating component (for example connected with the dome 2 ) through the skeleton 42 . The vibrating assembly includes a rectangular diaphragm 2 and a dome 1 combined in the middle of the diaphragm 2, and the dome 1 is designed as a flat plate. It should be noted that the vibrating membrane 2 and the dome 1 here are both strip-like structures, and this structural design can maximize the use of the effective radiation area and further optimize the acoustic performance of the product. The vibrating membrane 2 includes an edge portion bonded and fixed to the housing 5 and a ring disposed inside the edge portion, and the ...

Abstract

The invention discloses a sound production device which comprises a housing, a vibrating diaphragm connected and fixed with the housing and a voice coil unit combined with the vibrating diaphragm. The voice coil unit comprises a voice coil and a skeleton supporting the voice coil; the voice coil unit is connected with a centring disk; a signal access terminal electrically connected with an outgoing line of the voice coil is arranged on the housing; an abdicating portion formed by cutting is formed on the centring disk; and the outgoing line of the voice coil is led out by the abdicating portion and is electrically connected with the signal access terminal. The sound production device disclosed by the invention is excellent in low-frequency response, and cannot generate noise when carrying out high-power working.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a sounding device. Background technique [0002] At present, speakers have become a very popular electronic product, and with the continuous advancement of technology, consumers have higher and higher requirements for sound quality. For speakers, the speaker is the most basic sound unit, and the performance of the speaker directly affects the sound reproduction effect of the speaker. [0003] In the prior art, the lead-out line of the speaker voice coil is usually drawn from between the strut and the dome of the diaphragm, but when the product works under high power or has higher requirements on acoustic performance, the product often has a larger The amplitude, but if you want to obtain higher acoustic performance, you need to ensure that the product will not have noise. However, there is a risk that the lead-out wire of the voice coil hits other components in the way of the le...
