Abstract

The invention discloses a sound production device and head-mounted electronic equipment. The sound production device comprises a shell body and a sound production unit, wherein the sounding unit comprises a magnetic circuit system, a first vibration system and a second vibration system; the magnetic circuit system comprises a magnetic plate, and a first magnetic circuit structure and a second magnetic circuit structure which are arranged on two opposite sides of the magnetic plate; a first magnetic gap is formed in the first magnetic circuit structure; a second magnetic gap is formed in the second magnetic circuit structure; the first vibration system is arranged corresponding to the first magnetic circuit structure; the first vibration system is provided with a first voice coil extendinginto the first magnetic gap; the second vibration system is arranged corresponding to the second magnetic circuit structure; and the second vibration system is provided with a second voice coil extending into the second magnetic gap. The sound production device of the invention can reduce the vibration of the shell body of the sound production device.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a sound emitting device and head-mounted electronic equipment. Background technique [0002] With the progress of society and the development of science and technology, users have an increasing demand for the experience of head-mounted electronic devices with speakers. At present, most of the head-mounted electronic devices with speakers have the problem of shell vibration. VR (Virtual Reality , virtual reality equipment) as an example, speakers in VR generally pursue high low-frequency sensitivity in order to bring consumers a better experience, while pursuing low sensitivity, it will inevitably lead to a low resonance frequency of the product. When the speaker is working, The low-frequency amplitude is large, and at the same time, it brings a serious problem. The large amplitude causes the vibration of the VR peripheral shell to be large, and the consumer exper...
