The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Embodiment
As shown in figure 1, disclosing a kind of television set keying volume control circuit in the present embodiment, above-mentioned television set includes distant
Control device 10, loudspeaker 20, the TV main frame and display screen that are assembled into one, above-mentioned TV main frame have host chip MCU, above-mentioned
Remote control 10 has volume knob, and the triggering letter heightened volume or turn down volume can be sent by volume knob
Number, above-mentioned keying volume control circuit includes mute control, and above-mentioned remote control 10 is wirelessly connected to mute control, above-mentioned quiet
Sound controller control connection loudspeaker 20, the trigger signal that above-mentioned mute control sends according to volume knob is beaten to adjust
On or off is closed and states loudspeaker 20, and above-mentioned volume knob closes above-mentioned loudspeaker when sending the trigger signal for turning down volume
20.When operator adjusts television sound volume by remote control 10, the triggering letter of the mute control identification volume knob of design
