Referring to FIG. 2 , in an embodiment, the voice signal transmission circuit may include a signal coupling circuit 10 disposed on the remote control end, and a signal receiving circuit 20 and a signal amplifying circuit 30 disposed on the television end. The signal receiving circuit 20 and the signal amplifying circuit 30 are in signal connection, and the signal coupling circuit 10 and the signal receiving circuit 20 are connected through a laser path. The signal coupling circuit 10 on the remote control end can send out an electromagnetic wave signal, and the electromagnetic wave signal can be received by the signal receiving circuit 20 .

When the user triggers the voice button on the remote controller, the voice collection module 50 on the remote controller can collect the voice sent by the user to generate user voice data. After receiving the user's voice data, the signal coupling circuit 10 can convert the user's voice data into an electromagnetic wave signal by means of signal coupling, and send the signal to the signal receiving circuit 20 provided at the TV end. Among them, the electromagnetic wave signal can be a laser signal, and the laser signal has the advantages of good directionality and strong anti-interference ability. Even if it is reflected by the wall for many times, signal data will not be lost.

When the signal receiving circuit 20 receives the electromagnetic wave signal, it can convert the electromagnetic wave signal into a voltage signal so that the main control chip 40 at the TV end can identify the signal, and the signal receiving circuit 20 can output the voltage signal to the signal amplifying circuit 30 for processing.

The first capacitor C1 can filter the DC interference signal, so that the signal received by the base of the first transistor Q1 is the user's voice signal. When the voice signal is at a high level, the base of the first transistor Q1 is at a high level, the first transistor Q1 is turned on, and the first laser diode D1 emits light; and when the voice signal is at a low level, the first transistor Q1 is at a low level. The base of the transistor Q1 is at a low level, the first transistor Q1 is turned off, and the first laser diode D1 does not emit light.

The second capacitor C2 can play the role of isolating the DC interference signal. When the resistance value of the photoresistor Ldr changes according to the electromagnetic wave signal, the changed voltage signal is sent to the signal amplifying circuit 30 .
