Problems solved by technology

Conductive leads, FPC and other flexible conductive materials are used to inject them into the silicone film to replace the suspended leads, thus fundamentally solving the problem of disconnection under high temperature and high power, and using a symmetrical injection molding process to solve the problem of compliance. The problem of symmetry suppresses the swing mode and greatly improves the reliability of the product

Embodiment 1

[0027] Embodiment 1 Sound-generating device

[0028] Such as Figure 1-2 As mentioned above, the present invention provides a sound generating device, including a diaphragm 1 , a frame 2 , a lead wire 3 , a dome 4 , a voice coil 5 , a pole piece 6 , a magnetic steel 7 , a magnetic cover 8 , and a frame 9 .

[0029] The diaphragm 1, frame 2, leads 3 and dome 4 are integrated into a vibration system through hot pressing or injection molding process, and the leads 3 can also be replaced by FPC or flexible conductive materials.

[0030] The voice coil 5, pole piece 6, magnetic steel 7 and magnetic cover 8 form a magnetic circuit system.

[0031] The basin frame 9 becomes a supporting system that plays a role in connecting the vibration system and the magnetic circuit system.

[0032] Diaphragm 1, frame 2, lead wire 3 and dome 4 of the present invention are integrally hot-pressed or injected, and two lead terminals 51 of voice coil 5 are welded to two pads 41 of dome 4, and lead ...

Abstract

The invention provides a sound-generating device, which includes a vibrating system and a supporting system, and the vibrating system and the supporting system are connected together through a basin frame. The sound generating device of the present invention adopts conductive leads, FPC and flexible conductive materials, which are injected into the silicone film to replace the suspended leads, thereby fundamentally solving the problem of disconnection under high temperature and high power. At the same time, a symmetrical injection molding process is adopted to solve The problem of compliance asymmetry is solved, the swing mode is suppressed, and the reliability of the product is greatly improved. It not only improves the reliability of the product, but also improves the product performance.

Description

technical field [0001] The invention relates to a sounding device, in particular to a sounding device, which belongs to the technical field of electronic components. Background technique [0002] As a wireless terminal, smart phones have become an indispensable daily necessities for people; the rapid popularization and development of smart phones has brought rapid progress in micro speakers. However, as mobile phones require high power, small size, and high performance for speaker products, the existing technology is increasingly unable to keep up with the requirements of mobile phones. Therefore need a kind of new technology, product to solve this sharp contradiction. [0003] The conduction of the voice coil of a traditional speaker depends on two wires drawn from the voice coil body. In the design of conventional speakers, the middle parts of these two wires are suspended in the speaker, or fixed on the surface of the diaphragm by soft glue, and the ends of the lead wir...
