Sound output control method and system

Abstract

A sound output control method and a sound output control system are applied to the technical field of electronic devices and communication, and the method comprises the following steps: establishing data connection with searched audio and video acquisition equipment in a local area network to which the audio and video acquisition equipment belongs; when the ultrasonic audio modulation mode switching instruction is triggered, controlling each dual-mode loudspeaker in a sound amplification matrix to enter an ultrasonic audio modulation mode, and enabling each dual-mode loudspeaker to output sound picked up by a microphone in an ultrasonic carrier mode; adjusting the sound output direction of a target dual-mode loudspeaker corresponding to the target user; and when the audio broadcasting modeswitching instruction is triggered, controlling each dual-mode loudspeaker to enter an audio broadcasting mode. According to the method and the system, dual-mode sound output and free switching of ultrasonic directional sound output and general audio broadcasting can be realized.

Description

technical field [0001] The invention belongs to the technical field of electronic devices and communication, and in particular relates to a sound output control method and system. Background technique [0002] Such as figure 1 As shown, the existing sound amplification equipment usually consists of a microphone, an amplifier and a common loudspeaker. On the one hand, since the sound from the ordinary speaker will return to the microphone again, then amplify, and then return to the microphone, such a reciprocating cycle will form positive feedback, which will eventually lead to harsh howling when the sound amplification equipment is in use. problem, along with echo or reverberation and indistinct sound. On the other hand, since the sound will be transmitted through the doors and windows, there are also certain potential information security risks. Contents of the invention [0003] The present invention aims to provide a sound output control method and system, which can ...

AI Technical Summary

Problems solved by technology

On the one hand, since the sound from the ordinary speaker will return to the microphone again, then amplify, and then return to the microphone, such a reciprocating cycle will form a positive feedback, which will eventually lead to harsh howling when the sound amplification equipment is in use. problems with echo or reverberation and unclear sound

On the other hand, since the sound will be transmitted through the doors and windows, there are also certain hidden dangers to information security.
