WIPO Patent Application WO/2022/206013
Kind Code:
A1
Abstract:
Disclosed are a sound generating device and a smart watch. The sound generating device comprises a housing, a mounting frame and a vibration system, wherein the mounting frame comprises a bottom plate, two connecting pieces respectively connected to two ends of the bottom plate, and two mounting plates respectively connected to the connecting pieces in one-to-one correspondence; the bottom plate is fixed to the housing to form an accommodating cavity used for accommodating a magnetic circuit system of the sound generating device; the connecting pieces are bent in a direction from the bottom plate to be close to the housing; the mounting plates are bent in a direction from the connecting pieces to be away from the housing; the mounting plates are configured to be fixed to a housing of the smart watch, and are arranged in parallel or obliquely relative to the bottom plate; the vibration system comprises a vibrating film fixed to the housing; and the vibrating film is curved and protrudes in a direction away from the bottom plate. The present utility model has the advantages of the sound generating device not only occupying a small space of the smart watch but also improving the acoustic performance.
