Abstract

The invention provides a sounding device, which includes a sounding unit, the sounding unit includes a diaphragm for vibrating and sounding, and the sounding device also includes a cover on the side of the diaphragm away from the sounding unit. The metal front cover and the sealing layer attached to the side of the metal front cover away from the diaphragm, the metal front cover is separated from the diaphragm to form a sounding front cavity, and the metal front cover is provided with a And the sound hole opposite to the diaphragm, the sound hole communicates the sound front cavity with the outside world, and the sealing layer is completely located in the positive projection of the metal front cover along the vibration direction of the diaphragm within the range of the metal front cover. Compared with related technologies, the volume of the sound emitting device of the present invention is smaller.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a sound generating device used in electronic sound box products. 【Background technique】 [0002] Sound generating devices, also known as loudspeakers or horns, are used in speakers to convert audio signals into sound playback. [0003] The sound-generating device in the related art includes a sound-generating unit, the sound-generating unit includes a diaphragm for vibrating and sounding, and the sound-generating device also includes a front chamber covered by the diaphragm and the diaphragm to form a sound-emitting front cavity together. The front cover is provided with a sound hole passing through it, and the sound hole communicates the sound front cavity with the outside world. [0004] However, in the sound emitting device of the related art, although the waterproof effect is good, the front cover is made of plastic, and its thickness is relatively large, resultin...
