Abstract
The utility model discloses a speaker volume control system, including sound sensor, control module, operating device and speaker, sound sensor is used for gathering external noise intensity and transmits for control module, control module makes real-time response according to its noise intensity of receiving, to operating device sends the instruction, through operating device is right the volume of speaker is adjusted. This volume control system passes through sound sensor and gathers external noise intensity and feeds back to control module, and control module makes real-time response according to the noise intensity that it received, adjusts the volume of speaker to reduce the speaker volume in quiet highway section, avoid causing noise pollution, improve the speaker volume in noisy highway section, guarantee effectual effect of whistling.
Description
Technical Field
The utility model relates to a speaker equipment field, concretely relates to speaker volume control system.
Background
The existing automobile loudspeaker can not adjust the volume according to the real-time road condition, the loudspeaker sound in a quiet road section is relatively large, so that the noise pollution is caused, and the loudspeaker sound in a noisy road section is relatively small, so that the whistle function cannot be achieved, and therefore improvement is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a speaker volume control system to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a speaker volume control system, includes sound sensor, control module, operating device and speaker, sound sensor is used for gathering external noise intensity and transmits control module, control module makes real-time response according to the noise intensity that it received, to operating device sends the instruction, through operating device is right the volume of speaker is adjusted.
Preferably, for the loudspeaker volume control system, the operating mechanism includes an electromagnetic valve and an adjustable resistor connected in series with the loudspeaker in the same circuit, the electromagnetic valve is connected with the control module and used for driving the adjustable resistor to act according to the instruction of the operating module, so as to adjust the resistance value of the adjustable resistor, and the current of the circuit where the loudspeaker is located is changed through the change of the resistance value of the adjustable resistor, so as to adjust the volume of the loudspeaker.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a speaker volume control system, it gathers external noise intensity and feeds back to control module through sound sensor, and control module makes real-time response according to the noise intensity that it received, adjusts the volume of speaker to reduce the speaker volume in quiet highway section, avoid causing noise pollution, improve the speaker volume in noisy highway section, guarantee effectual whistling effect.
