The beneficial effects of the utility model are:
A kind of television set with wireless audio transmitter of the utility model is by wireless transmitter module wireless transmission audio signal, transfer to outside wireless playing equipment and carry out output broadcasting, make user when needs audio plays, without the need to carrying out wiring again, greatly user-friendly, and the utility model structure is simple, greatly reduces use cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Fig. 1 is the functional-block diagram of a kind of television set with wireless audio transmitter of the utility model;
Fig. 2 is a kind of circuit theory diagrams with high-pass filtering circuit in the television set of wireless audio transmitter of the utility model.
Embodiment
With reference to figure 1, a kind of television set with wireless audio transmitter of the utility model, comprise audio frequency and video processing module, audio amplification block, loud speaker, display module and wireless transmitter module, first output of described audio frequency and video processing module is by audio amplification block and then be connected with the input of loud speaker, second output of described audio frequency and video processing module is connected with the input of display module, and the input that the 3rd output and the wireless transmitter module of described audio frequency and video processing module connect is connected.
Be further used as preferred embodiment, described wireless transmitter module comprises audio emission processing module and transmitting antenna, and the 3rd output of described audio frequency and video processing module is by audio emission processing module and then be connected with the input of transmitting antenna.
Be further used as preferred embodiment, also high-pass filtering circuit is connected with between the input of described transmitting antenna and the output of audio emission processing module, can the low-frequency disturbance composition effectively in filtered signal and the DC signal with many interference signals by described high-pass filtering circuit.
Be further used as preferred embodiment, described audio emission processing module is also connected with memory module, and described memory module adopts 24C02 storage chip.
With reference to figure 2, be further used as preferred embodiment, described high-pass filtering circuit comprises the first inductance L 1, second inductance L 2 and the first electric capacity C1, the output of described audio emission processing module is connected to the first end of the first electric capacity C1, the input of described transmitting antenna is connected to second end of the first electric capacity C1, the first end of described first electric capacity C1 is connected to ground by the first inductance L 1, and second end of described first electric capacity C1 is connected to ground by the second inductance L 2.Wherein, the first inductance L 1, second inductance L 2 and the first electric capacity C1 of different numerical value can be selected as required, thus change the minimum cut-off frequency allowed by signal.
During the utility model specific works, described wireless transmitter module, when receiving the television audio signal transmitted of audio frequency and video processing module, first by audio emission processing module, wireless high-frequency signal is become to television audio signal transacting, then carry out filtering process by high-pass filtering circuit, finally by transmitting antenna, audio signal is sent to outside wireless playing equipment and plays.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
