Abstract
The utility model relates to a television set which can be inserted and connected with an infrared stereophone. The utility model is characterized in that a shell body of the television set is provided with an infrared stereo emitting insertion opening; leading wires of a base pin of the insertion opening are respectively connected with audio signal of a left and a right channels of television sound, control circuit working power supply of the television set, and a ground terminal, and is also connected with control signal outlet line of a CPU infrared emission switch of the television set; the insertion opening can be arranged at the back face or the side face or the front face or the top of the shell body of the television set. The utility model can omit special power supply of the existing infrared earphone transmitting device, and the transmitting device can be moved to the outside of the television set. The utility model as an option provides a convenient and flexible television set which can directly be inserted and provided with the transmitting device for users.
Description
The utility model relates to a kind of television set that can patch the infrared ray stereophone for the stereo emitter socket of grafting infrared ray that has.
For making things convenient for the user when appreciating TV programme, do not disturb other people, be not subjected to external interference, and for not being subjected to the restriction of signal output connection, all be provided with the stereo emitter of infrared ray in some television sets now, the user carries the stereophone of infrared receiver and listens to television audio.For example the applicant, formerly patent ZL97230773.7.This emitter is made up of audio frequency input circuit, modulator, power supply etc., and signal connects switching signal, the sound accompaniment left and right acoustic channels audio signal of the CPU infrared emission control of television set.Emitter emission infrared signal, again by this infrared signal of stereophone receiving system, this receiving system comprises that infrared ray receives amplifying circuit, frequency-selective network, frequency discriminator, low discharging circuit and loudspeaker and forms.12V (or 9V, 15V) dc power supply of the essential configure dedicated of the emitter of existing this stereophone.Emitter is arranged in the television set like this, client can not select whether to need to increase this accessory when buying, and conventional device need dispose power supply, the user is when using Infrared earphone to listen to television audio, external power supply need be opened, could produce and transmit, obtain received signal.
The purpose of this utility model is to provide a kind of television set that patches the infrared ray stereophone at the deficiency of prior art, can save the power source special of existing Infrared earphone emitter, and emitter moves on to outside the television set, become an option, for the user provide more convenient, flexibly, can directly plug the television set of emitter.
The purpose of this utility model is achieved in that a kind of television set that patches the infrared ray stereophone, the housing of television set is provided with the stereo emission socket of infrared ray, and this socket pin leads connects sound accompaniment left and right sound channels audio signal, television set control circuit working power and the earth terminal of television set respectively.
Described socket pin leads also can connect the CPU infrared emission switch controlling signal mouth line of television set.Socket can be located at back or side or the front or the top of tv shell.
According to the technique scheme analysis as can be known, the utlity model has following advantage:
1, both omitted existingly, be convenient to the output of television set CPU centralized control signal simultaneously again, therefore both utilized existing resource, saved expense for the user again at the necessary D.C. regulated power supply of the emitter of Infrared earphone.
2, Infrared earphone and emitter thereof itself are this external accessory of television set, so Infrared earphone and emitter thereof become the optional accessory that the user buys, uses, and the selection of multiple purchase is provided for client.
Very convenient when 3, using, as long as emitter is plugged on the special-purpose socket, need not extraneous again power supply.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model circuit theory diagrams;
Fig. 2 is the utility model structural representation.
Referring to Fig. 1,2, the utility model is a kind of television set that patches the infrared ray stereophone.The housing 7 of television set is provided with the stereo emission socket 6 of infrared ray, the pin leads of this socket 6 connects CPU infrared emission switch controlling signal line 1, sound accompaniment left channel audio signal 4, right channel audio signal 5, television set control circuit working power 3 and the earth terminal 2 (no matter which kind of model television set CPU is, all can draw above holding wire) of television set respectively.Socket 6 concrete structures can be Din, and its pin directly is welded on the TV SKD, the extended tv shell 7 in socket 6 ends that connects with emitter.During use, the plug of the emitter of Infrared earphone is inserted in the socket, transmitting tube gets final product facing to the beholder of the Infrared earphone that has receiving system.Therefore, the user simple, convenient, listen to beautiful television field frame by the infrared ray stereophone like a cork.
For satisfying the custom demand of different user, socket 6 can be located at back or side or the front or the top of tv shell 7.
