Document Type and Number:
WIPO Patent Application WO/2024/055384
Kind Code:
A1
Abstract:
Provided in the embodiments of the present invention is a multifunctional sound production device, comprising a housing, a sound production unit, and a motor assembly provided with a coil element. The sound production unit comprises a basket, a vibration system, and a magnetic circuit system having a magnetic gap, wherein the vibration system is driven by the magnetic circuit system to vibrate in a first direction so as to produce sound; the magnetic circuit system is elastically connected to the housing by means of an elastic arm; the center of the magnetic circuit system is provided with a through hole; the motor assembly is accommodated in the through hole, and the motor assembly comprises the coil element, which is fixed to the housing; and the coil element is spaced apart from the magnetic circuit system and drives the magnetic circuit system to vibrate in a second direction, the first direction being perpendicular to the second direction. Compared with related technology, the multifunctional sound production device of the present invention has a small overall thickness and a small size, provides a strong driving force by means of the motor assembly and has a minor effect on the driving force in the magnetic circuit system, and thus has excellent acoustic and vibration performances.
