Abstract

The embodiment of the invention discloses an acoustic generating device, comprising a sealing chamber, a voice coil and a lead wire; the voice coil is composed of surrounding lead wires and is arranged in the sealing chamber; the lead wire is connected with the voice coil and is led out from a lead wire hole on the sealing chamber; the sealing chamber is fixed on a machine shell of electrical equipment by a fastener, and the voice coil is connected into an audio-frequency electrical signal of the electrical equipment by the lead wire. By adopting the embodiment of the invention, the acoustic generating device is fixed on the machine shell of the electrical equipment, and sounding effect can be realized by utilizing resonance, the structure is simple and the reliability is high; in addition, a sounding hole does not need to be arranged on the machine shell of the electrical equipment, thereby not affecting appearance of the electrical equipment.

Description

technical field [0001] The invention relates to a sound generating device, in particular to a sound generating device which utilizes resonance to realize a sound effect. Background technique [0002] At present, in existing electrical products, the sound generating device is generally arranged inside the body, and sound holes are provided on the casing to facilitate the diffusion of sound waves. However, the design of the sound hole on the shell destroys the overall consistency of the appearance and affects the appearance quality of the product. Especially in TV products, the mold with a large area of ​​sound hole is complicated to make and easy to damage, and the maintenance cost after damage high. Contents of the invention [0003] Embodiments of the present invention provide a sound generating device, which utilizes resonance to achieve a sound effect, and has a simple structure and high reliability. [0004] An embodiment of the present invention provides a sounding ...
