Vibration driving apparatus

Abstract

A vibration driving apparatus comprises a vibration member and a vibration apparatus configured to vibrate the vibration member to generate sound. The vibration apparatus includes a sound generating module and at least one vibration module connected to the sound generating module. The sound generating module may generate vibrations based on a supplied current, while the vibration module may include a film-type piezoelectric structure that vibrates based on a drive signal. The vibration apparatus may be on a rear surface of the vibration member such that sound is emitted from a front surface of the apparatus. Integration of the sound generating module and the vibration module may enhance sound pressure level characteristics across mid to high frequency bands and enable multi-panel sound output. This configuration may reduce structural complexity, improve reliability, and simplify manufacturing by allowing the vibration apparatus to function both as a sound source and as a vibration actuator.
