Document Type and Number:
WIPO Patent Application WO/2022/148116
Kind Code:
A1
Abstract:
Disclosed are a sound generation apparatus and an electronic device. The sound generation apparatus comprises a first main body and a second main body which is opposite the first main body, wherein 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 an inverter tube arranged in the second cavity; when the sound generation apparatus is in a first state, the first cavity forms a sound cavity of the first electroacoustic unit, and the first cavity is isolated from the second cavity; and when the sound generation apparatus is in a second state, the first cavity is in communication with the second cavity so as to form a third cavity, and a common sound cavity of the first electroacoustic unit and the inverter tube is formed by the third cavity. The common sound cavity of the first electroacoustic unit and the inverter tube is formed by the third cavity, such that the inverter tube enhances sound output of the first electroacoustic unit, thereby improving the overall sound quality of the sound generation apparatus, and meeting diversified requirements.
