Abstract

The invention discloses a sound-generating device, which comprises a speaker unit and a peripheral casing for accommodating and fixing the speaker unit; the speaker unit includes a vibrating membrane; the space behind the vibrating membrane constitutes a rear acoustic cavity, and the rear The acoustic cavity is jointly formed by the speaker unit and the outer casing, and the rear acoustic cavity is a sealed structure, wherein the diaphragm is provided with leakage holes connecting both sides of the diaphragm, and the leakage holes are holes or slit-like structure. This structure balances the airflow in the rear acoustic cavity and adjusts the sound quality, thereby improving the acoustic performance of the sound-generating device with the fully sealed rear acoustic cavity.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a sounding device. Background technique [0002] The sound-generating device includes a loudspeaker unit and a peripheral casing. The loudspeaker unit includes a vibration system, a magnetic circuit system, and a protective frame for accommodating and fixing the vibration system and the magnetic circuit system. The vibration system usually includes a diaphragm and a voice coil combined on the lower side of the diaphragm, and the magnetic circuit system forms a magnetic gap for accommodating the voice coil. The space on the front side of the diaphragm of the sound-generating device forms the front acoustic cavity, and the space on the rear side of the diaphragm forms the rear acoustic cavity, and the front acoustic cavity and the rear acoustic cavity are mutually isolated structures. The rear acoustic cavity is the enclosed space between the loudspeaker unit and the peripheral she...
