Abstract
The utility model discloses a volume auto-controller for acoustics and TV, composed of a handset inductor, an amplifier and a control device. The output end of the handset inductor is coupled with the input end of the amplifier. The output end of the amplifier is coupled with the input end of the control device. The output end of the control device is connected with the volume control circuit of the acoustics and the TV. When a handset is used beside the acoustics or the TV provided with the utility model, the handset inductor picks the handset signal, and exports the signal into the input end of the amplifier. After being magnified by the amplifier, the control device exports a control signal, which makes the acoustics or TV played with preset volume. When the handset is out of use, the acoustics or the TV recovers the original volume automatically. The utility model can prevent the sound of the acoustics or TV affecting the usage of the handset.
Description
Technical field
The utility model relates to a kind of sound equipment, television sound volume automatic control equipment.
Background technology
Along with the fast development of mobile communication and the decline of mobile phone rate, main means of communication when mobile phone has become people's work or leisure.Conveniently moving, small and exquisite mobile phone bring great convenience for people's life, but the use of mobile phone also runs into some obstacles in some occasion, as when taking the automobile of opening sound equipment, family watch TV programme or participate in the less place of scope as KTV, when blocking recreational activities such as OK, dial or receive calls as need, the volume that in progress program produced can make you dial or to receive calls.
The utility model content
The purpose of this utility model is to provide a kind of sound equipment simple in structure, television sound volume automatic control equipment, this control device can make sound equipment or TV by predefined volume playback when answering or dial mobile phone, influences mobile phone with the sound that prevents sound equipment or TV and uses.
For achieving the above object, the utility model comprises
The mobile phone inductor, its output and amplifier input terminal couple, and are used to pick up mobile phone and use signal, and it is outputed to amplifier input terminal;
Amplifier, the input of its output and controller couples, and is used to amplify the output signal of mobile phone inductor;
Controller, its input and amplifier couple, and output connects with the volume control circuit of sound equipment, TV, and when amplifier had output, controller is exported a control signal made sound equipment, TV by predefined volume playback; During the amplifier no-output, no control signal output, sound equipment, TV recover original volume automatically.
Advantage of the present utility model: the utility model is installed in the volume control of sound equipment or TV, when using mobile phone in automobile or by the television set like this, the mobile phone inductor will be exported mobile phone and use signal, after amplifying, amplifier exports the volume control circuit of a control signal to automobile audio or television set by controller, the volume that makes sound equipment or TV is the set point that is adjusted in advance, so neither influence other people, but answer or dial to relaxation and happiness mobile phone again, after finishing using, volume can be recovered original state again automatically, has overcome existing sound equipment, television sound volume influences the shortcoming that mobile phone uses.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Fig. 2 is the structural representation of the utility model embodiment 1.
Fig. 3 is the structural representation of the utility model embodiment 2.
Embodiment
As shown in Figure 1, the utility model comprises mobile phone inductor 1, amplifier 2, controller 3, the input of the output of described mobile phone inductor 1 and amplifier 2 couples, the input of the output of amplifier 2 and controller 3 couples, and the output of controller 3 connects with the volume control circuit of sound equipment, TV.The utility model can directly be installed in sound equipment or the TV, when the next door of sound equipment or TV has mobile phone to use, mobile phone inductor 1 picks up mobile phone and uses signal, and it is outputed to the input of amplifier 2, after amplifier 2 amplified, controller 3 outputs one control signal made sound equipment, TV by predefined volume playback; When mobile phone is stopped using, amplifier 2 no-outputs, controller 3 is no-output also, and sound equipment, TV recover original volume automatically.
As shown in Figure 2, be the circuit diagram of the utility model embodiment 1.A is the mobile phone inductor among the figure, when sound equipment of the present utility model or TV being installed having mobile phone to use nearby, mobile phone inductor A is luminous to make photoelectrical coupler U conducting, 3 and the 4 end conductings of photoelectrical coupler U, bias current is provided for triode D, triode D conducting, the coil of engage relay J, the relay J closure, adjustable potentiometer W1 exports a fixed voltage to the Automatic control of sound volume circuit, makes sound equipment or TV by predefined volume playback, when mobile phone is stopped using, mobile phone inductor no-output, 3 and the 4 not conductings of end of photoelectrical coupler U, triode D ends, and relay J disconnects, adjustable potentiometer W1 does not have control signal output, and sound equipment or TV recover original tone playing state.
Fig. 3 is the circuit diagram of the utility model embodiment 2.A is the mobile phone inductor among the figure, and the output of mobile phone inductor is also received the base stage of triode G, when the mobile phone inductor has signal output, triode G conducting, relay J 2 closures, adjustable potentiometer W2 exports a fixed voltage to the Automatic control of sound volume circuit, makes sound equipment or TV by predefined volume playback, when mobile phone is stopped using, mobile phone inductor no-output, triode G ends, and relay J disconnects, adjustable potentiometer W2 does not have control signal output, and sound equipment or TV recover original tone playing state.
