Abstract

The invention discloses a sound production device and electronic equipment, the sound production device comprises a first main body and a second main body opposite to the first main body, the first main body is provided with a first cavity and a first electroacoustic unit, and the second main body is provided with a second cavity and a second electroacoustic unit; when the sound production device is in a first state, the first cavity forms a sound cavity of the first electroacoustic unit, the second cavity forms a sound cavity of the second electroacoustic unit, and the first cavity and the second cavity are mutually independent; when the sound production device is in a second state, the first cavity and the second cavity are communicated to form a third cavity, the third cavity forms a common sound cavity of the first electroacoustic unit and the second electroacoustic unit, the first electroacoustic unit projects sound into the third cavity, and the second electroacoustic unit projects sound out of the third cavity; and the vibration wave of the first electroacoustic unit and the vibration wave of the second electroacoustic unit are arranged in opposite phases. The sound production device can provide two sound production effects to meet diversified requirements.

Description

technical field [0001] The present application relates to the field of communication equipment, in particular to a sound generating device and electronic equipment. Background technique [0002] At present, the structural forms of mobile phones are becoming more and more diverse. Speakers are installed in mobile phones, and a closed cavity is provided corresponding to the speakers, so as to present a closed speaker structure. However, the structure of the cavity is relatively simple, resulting in a single sound effect of the speaker. Contents of the invention [0003] An embodiment of the present application provides a sound generating device, wherein the sound generating device includes a first body and a second body opposite to the first body, and the first body is provided with a first cavity and a first electro-acoustic unit , the second body is provided with a second cavity and a second electro-acoustic unit; when the sound generating device is in the first state, th...
