Problems solved by technology

[0003] However, in the process of use, it is found that the low frequency response of the piezoelectric driver is poor. In order to obtain a better low frequency response, the equalizer (Equalizer, EQ) can be changed by software to improve the low frequency response effect. However, the effect of debugging by software is limited. , poor low frequency response

Abstract

Embodiments of the invention disclose a device and a method for screen vocal control, and a terminal, and the device and the method are applied in the field of screen vocal technique. The device for screen vocal control comprises a digital signal processor, a coder-decoder, a frequency divider, an amplifier, a driver, a motor, and a middle frame. The digital signal processor is used to perform analog-digital conversion processing on audio signals, to obtain digital signals. The coder-decoder is connected with the output end of the digital signal processor, and decodes digital signals to obtain decoded signals. The frequency divider is connected with the output end of the coder-decoder, and obtains high-frequency signals and low-frequency signals in the decoded signals. The amplifier is used to perform amplification processing on the high-frequency signals. The driver is connected with the output end of the amplifier, and drives a display screen to vibrate to sound. The motor is connected with the low-frequency signal output end of the frequency divider. The middle frame is connected with the motor, and the motor drives the middle frame to vibrate, so that the middle frame drives the display screen to vibrate and sound. Using the device and the method can ensure good low-frequency response effect of a screen vocal terminal.

Description

technical field [0001] The present invention relates to the technical field of screen sound generation, in particular to a screen sound control device, method and terminal. Background technique [0002] With the development of terminal technology, smart phones using screen sound technology began to appear. The so-called screen sound smart phone is to apply the world's leading screen sound, that is, "piezoelectric driver technology" to smart phones, so that the earpiece function and plane conversion (InPlane Switching, IPS) high-definition screen perfectly integrated smart phone, no need to set the earpiece sound hole on the front of the phone. When the piezoelectric actuator is powered on, the phone's touch screen vibrates, which in turn pushes the air to produce sound. [0003] However, in the process of use, it is found that the low frequency response of the piezoelectric driver is poor. In order to obtain a better low frequency response, the equalizer (Equalizer, EQ) can...
