Abstract

The invention discloses a sounding unit. The sounding unit includes a magnetically conductive yoke and a casing that cooperate to form a storage space, and a magnetic circuit system and a vibration system arranged in the storage space; the vibration system includes a The diaphragm on the casing, the voice coil for driving the diaphragm to vibrate, and the dome arranged on the diaphragm, the magnetic circuit system has a magnetic gap, and the voice coil is inserted into the magnetic gap; the dome It is divided into a small amplitude deviation area and at least one large amplitude deviation area, and one or more leakage holes are opened in the large amplitude deviation area. The technical solution of the invention can reduce the polarization and improve the sound quality of the sounding unit.

Description

technical field [0001] The invention relates to the technical field of electro-acoustic conversion, in particular to a sound-generating monomer. Background technique [0002] The sound-generating unit of the related art includes a magnetic circuit system, a vibration system, and a casing for accommodating the magnetic circuit system and the vibration system. After the voice coil is connected to the current, it moves and drives the diaphragm to vibrate, and the air in the rear cavity will be compressed or expanded to produce sound. During the movement of the voice coil, the vibration system may be polarized by the structure of the sounding unit itself, which makes the vibration amplitude of each part of the diaphragm inconsistent and affects the sound quality of the product. [0003] Therefore, it is necessary to provide a new type of sound generator to solve the above problems. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to provide a so...
