MULTIFUNCTIONAL SOUND PRODUCTION DEVICE

WIPO Patent Application WO/2024/050885

A1

A multifunctional sound production device, comprising a shell having an accommodation cavity, and a sound production driver suspended in the accommodation cavity, wherein the sound production driver comprises a frame, a vibration system fixed into the frame, and a magnetic circuit system, which drives the vibration system to vibrate in a first direction to sound and has a magnetic gap. The multifunctional sound production device is characterized by further comprising a vibrator, which is suspended in the accommodation cavity and is located on the side of the magnetic circuit system away from the vibration system, and a coil assembled on the vibrator, wherein the magnetic circuit system and the coil interact with each other, so as to drive the vibrator to vibrate in a reciprocating manner in a second direction, the magnetic circuit system drives the sound production driver to vibrate in a reciprocating manner in the second direction, and the second direction is perpendicular to the first direction. The vibration system and the vibrator share the magnetic circuit system, and the sound production driver and the vibrator are assembled in one shell, such that the space occupied thereby is greatly reduced; and the sound production driver and the vibrator form a dual-vibration system, which improves a vibration effect, and avoids an additional component, thereby further saving on space.
