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, the first housing and the second housing are matched to form an inner cavity, and the second housing is provided with a hollow area; the sound production single body is accommodated in the inner cavity and is matched with the first shell to form a front cavity, the sound production single body blocks the hollow area, and a leakage hole is formed in the sound production single body; the metal isolation net covers the sound production single body and covers the leakage hole, a rear cavity is defined by the metal isolation net, the first shell and the second shell, the rear cavity is filled with sound absorption particles, the metal isolation net is used for isolating the sound absorption particles from entering the leakage hole, and the metal isolation net is of an annular frame-shaped structure surrounding the periphery of the sound production single body; the end face of the metal isolation net away from the front cavity is lower than or flush with the surface of the sounding monomer away from the front cavity. According to the sound production device, the maximum filling design of the sound production device can be realized, and the light and thin design of a mobile phone is realized while the acoustic performance of the sound production device is improved.

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 transducer devices 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, consumers have higher requirements for speakers, requiring larger back chambers and better acoustic performance. However, the contradiction is that the mobile phone is also required to be as thin and light as possible, and the cavity expansion and height of the sound-emitting device are limited, and even compression is required. In order to improve the acoustic performance, the existing practice is usually to fill the sound-absorbing particles in the back cavity, and further set...
