Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 to Figure 4 As shown, it is a sounding device provided by Embodiment 1 of the present invention. The sounding device includes an upper cover 1, a lower cover 2 enclosing the upper cover 1 to form a storage space 50, and a sounding unit 3 accommodated in the storage space 50. The sounding unit 3 has a diaphragm 31, and the upper cover 1 includes a top wall 12 facing the diaphragm 31 and a side wall 13 extending from the top wall 12 to a direction close to the diaphragm 31 to fix the sounding unit 3, and the upper cover 1 is provided with The sound hole 11 , the top wall 12 , the side wall 13 and the diaphragm 31 enclose the front cavity 4 .

[0024] In the above embodiment, if image 3 and Figure 4 As shown, the upper cover 1 also includes a recessed portion 14 that is recessed from the top wall 12 to the direction away from the...

Abstract

The invention provides a sounding device, which comprises an upper cover, a lower cover which surrounds the upper cover to form a storage space, and a sounding unit housed in the storage space, the sounding unit has a diaphragm, and the upper cover includes a top facing the diaphragm wall and the side wall of the fixed sounding unit extending from the top wall to the direction close to the diaphragm. A recessed portion that is recessed away from the diaphragm, the recess includes a first surface facing the diaphragm and a second surface connecting the first surface and the top wall, the first surface extends from the second surface to the sound outlet to the sound outlet In the hole, the second surface spans from one sidewall to the opposite sidewall. In the present invention, the air pressure on both sides of the front chamber area between the dome of the sounding unit and the upper cover is effectively dredged, so that the pressure in each place inside the front chamber is balanced, and the problem of vibration membrane swing can be improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of electroacoustics, and in particular relates to a sound-generating device. 【Background technique】 [0002] With the rapid development of science and technology, in the process of rapid development of audio equipment, people have more and more functional requirements for products. For sound-generating devices, more and more people have put forward higher requirements for their audio performance. In the related art, the height from the dome of the sounding device to the upper cover is consistent, resulting in an imbalance of air pressure in the front chamber between the dome and the upper cover, and the diaphragm of the sounding device swings seriously. 【Content of invention】 [0003] The object of the present invention is to provide a sound-generating device, aiming to solve the problem in the prior art that the air pressure inside the front cavity of the sound-generating device is unbalanced, causing t...
