Sounding device and electronic device

Abstract

The invention discloses a sound production device and an electronic device, and the sound production device comprises a housing which comprises a first housing and a second housing, and the first housing and the second housing cooperate to form an inner cavity; the sound production single body is accommodated in the inner cavity and is matched with the first shell to form a front cavity, and a leakage hole is formed in the sound production single body; the breathable isolation piece covers the sound production single body and covers the leakage hole, and a rear cavity is defined by the breathable isolation piece, the first shell and the second shell; the rear cavity is filled with sound absorption particles, the breathable isolation piece is used for isolating the sound absorption particles from entering the leakage holes, and a magnetic isolation layer is arranged on the breathable isolation piece. The sound production device is provided with the breathable separator, and the breathable separator is used for isolating the sound absorption particles in the rear cavity from entering the leakage hole, so that the normal work of the sound production single body is ensured. And moreover, the isolation layer is arranged on the breathable isolation piece, and the magnetic isolation layer has a magnetic isolation effect, so that the effect of optimal acoustic performance is achieved while the magnetic flux diffused outwards by the sound production single body reaches the minimum.

Description

technical field [0001] The invention relates to the technical field of electro-acoustics, and in particular, to a sound-generating device and an electronic device. Background technique [0002] Sound-emitting devices, such as speakers, are transducers that convert electrical signals into sound signals, and are now widely used in electronic devices such as mobile phones, computers, and earphones. With the rapid development of electronic devices such as mobile phones, computers, and headphones, more and more functions are integrated into electronic devices, such as mobile phones. The magnetic field emitted by the speaker to the outside may affect the normal operation of the components integrated around the speaker. Therefore, , the smaller the magnetic flux emitted by the loudspeaker, the higher the acoustic reliability of the loudspeaker. However, it is difficult for the existing sound-emitting devices to satisfy the pursuit of optimal acoustic performance while minimizing t...
