Abstract

The present invention provides a drive system of a multi-function voice device. The drive system of the multi-function voice device comprises a power amplifier and the multi-function voice device. The power amplifier includes audio input end, a vibration drive signal generation unit, a power amplifying assembly and an output end. The audio input end is used for receiving audio drive signals. The vibration drive signal generation unit is used for generating corresponding vibration drive signals according to received vibration prompt enable signals or touch vibration response enable signals. The power amplification assembly is used for performing signal amplification processing on audio drive signals and / or vibration drive signals received by the power amplification assembly, and outputs the processed signals to the multi-function voice device. The multi-function voice device is used for performing corresponding audio playing and / or vibration processing under the drive of the audio drive signals and / or vibration drive signals received by the multi-function voice device. The invention simultaneously provides the power amplifier applicable to the drive system of the multi-function voice device.

Description

【Technical field】 [0001] The present invention mainly relates to a driving system of a multi-function sounding device (Multi-function Device, MFD) and a power amplifier (Power Amplifier, PA) applicable to the driving system. 【Background technique】 [0002] With the development of wireless communication technology and mobile Internet technology, mobile terminal devices such as smart phones have gradually become people's daily communication and entertainment tools. A speaker and a vibration motor are respectively arranged inside a traditional mobile terminal device; wherein, the speaker is used to convert an audio signal into a sound signal so that the user can listen to music and ringtones through the mobile terminal device, and the vibration motor is used to The terminal device provides a vibration reminder to the user when receiving an incoming call or message, or provides vibration feedback to the user when the user performs a touch operation. [0003] At present, mobile ...
