The invention discloses a sound production device and electronic equipment. The sound production device comprises a shell and a loudspeaker single body, wherein two opposite sides of the shell are respectively provided with a front sound cavity and a rear sound cavity; the loudspeaker single body is fixed on the shell, and the sound outlet end of the loudspeaker single body is communicated with the front sound cavity; and the shell is provided with a leakage structure, and the leakage structure comprises a resistance silencing cavity separated from the rear sound cavity, a first leakage hole communicating with the rear sound cavity and the resistance silencing cavity, and a second leakage hole communicating with the resistance silencing cavity and the front sound cavity. According to the technical scheme, airflow disturbance noise at the leakage structure on the sound production device can be reduced, the symmetry of vibration displacement of the product is improved, and thus the acoustic performance of the product is improved.
Description
technical field [0001] The invention relates to the technical field of electroacoustic equipment, in particular to a sound generating device and electronic equipment. Background technique [0002] A common sound generating device usually includes a casing and a speaker unit disposed on the casing, and the opposite sides of the casing are respectively a front sound cavity and a rear sound cavity. The shell is usually provided with a leakage hole for connecting the rear acoustic cavity and the front acoustic cavity. However, the airflow disturbance noise will be generated at the leakage hole, which will affect the symmetry of the vibration displacement of the product, thus causing users to be unsatisfied with the stability of the product's acoustic performance. Contents of the invention [0003] The main purpose of the present invention is to propose a sounding device, which aims to reduce the airflow disturbance noise at the leaking structure on the sounding device, improv...
