Abstract

The invention provides a sounder which comprises a shell, a vibration system accommodated in the shell and a magnetic circuit system matched with the vibration system together. The vibration system comprises a vibration diaphragm and a voice coil combined on the vibration diaphragm; the vibration diaphragm divides an inner cavity of the shell into a front cavity and a rear cavity; the vibration diaphragm is provided with a hollow-out part; the sounder further comprises a heat dissipation part fixed at the rear cavity; the heat dissipation part extends to the front cavity by the hollow-out part; and the vibration diaphragm further comprises a connection part connected with the heat dissipation part. According to the sounder provided by the embodiment of the invention, by arranging the heatdissipation part, efficient heat conduction can be carried out between the front and rear sound cavities, so that heat of the rear cavity is rapidly conducted to the front cavity by the heat dissipation part, problems of wire breakage, wire dispersion and the like of the voice coil, which are caused by heat accumulation in the rear cavity, can be avoided, and the service life of the sounder is prolonged.

Description

technical field [0001] The invention relates to the technical field of acoustic-electric conversion. More specifically, it relates to a sound generator. Background technique [0002] The sound generator is an important acoustic component of portable electronic equipment, which is used to complete the conversion between electrical signals and sound signals, and is an energy conversion device. Existing sound generators generally include a casing, and a vibration system and a magnetic circuit system are accommodated in the casing. Among them, the vibration system includes a diaphragm and a voice coil fixed together, the magnetic circuit system includes a magnetic yoke and a magnet and a magnetic plate fixed on the magnetic yoke in turn, the diaphragm includes a fixed part fixed to the sounder shell, and The ring part integrally provided with the fixing part is located at the central part in the ring part and the reinforcing part provided on one side of the central part. The ...
