Abstract

The utility model belongs to a remote control device for television sets. The utility model makes appropriate change on the circuit of the infrared remote control part of a presently prevalent television set. A coaxial cable and a related circuit of the utility model are used to realize the cable remote control (wire control) function of the television set. Simultaneously, the cutoff of the loudspeaker of the television set on the remote control transmitting end and the use of an earphone to listen to the sound signal of the television set are realized. The utility model enables a passenger to carry out all the functions of the television set on a bed. The utility model has the advantage of reasonable design.

Description

Wire controlling TV set and bedside cabinet with a remote TV controller

The utility model belongs to the remote control of television set.

The guest room at existing hotel, hotel, bedside cupboard is provided with the device of switch television set function, and other functions can not be implemented; For the distance type television set, remote-control box is small and exquisite, and is very easy to use, but since small and exquisite, lose easily, and many people are lived in the guest room, are not easy to management and use.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of guest room bedside cupboard of providing can be implemented the wire controlled television set and the TV Full remote controlled bedside cupboard of television set repertoire.

The purpose of this utility model can realize by following measure:

In the bedside cupboard in guest room, existing hotel, hotel, wire controlled television set and TV Full remote controlled line construction are set, in bedside cupboard front plate upper end remote keying, switch and earphone jack are set, finish the transmission of various signals by coaxial cable, realized to listen to television field frame at transmitting end with earphone in the switching of transmitting end remote-controlled television set and control loudspeaker and earphone.

The keying line structure is that the remote signal that TV remote controller A sends is taken out from infrared transmission level transistor collector through capacitor C 1(, infrared transmission diode can replace with resistance) (R1 is a build-out resistor to send into 1 end of coaxial cable L, for the approximate short circuit of remote signal C2) be transferred to 2 ends of L through L, and in capacitor C 3 is coupled to TV remote-control receiving box B the negative pole of infrared receiving diode, thereby (R3 is the cable output end build-out resistor to finish straighforward operation, capacitor C 4, C5 is to the also approximate short circuit of remote signal) (R1 is a build-out resistor to switch W in order to 1 end of the adhesive cable L of control relay J, for the approximate short circuit of remote signal C2) be transferred to 2 ends of L through L, and in capacitor C 3 is coupled to TV remote-control receiving box B the negative pole of infrared receiving diode, thereby (R3 is the cable output end build-out resistor to finish straighforward operation, capacitor C 4, C5 is to the also approximate short circuit of remote signal) switch W is in order to adhesive and the release of control relay J, when W disconnects, J is in no electric release conditions, its normally-closed contact is sent sound accompaniment C into TV loudspeaker Y1, use the loudspeaker playback, when W is closed, J gets electric adhesive, the normally opened contact closure, audio signal C is through R4, C4, R3 sends into 2 ends of L, and (C5 is used for the high fdrequency component of filtering audio signal, avoid its interference) to remote signal, deliver to 1 end of L through L, again through R1, C2 delivers to little loudspeaker Y2(of transmitting end or earphone), listen to television field frame thereby be implemented in transmitting end with earphone.And release, when W disconnected, J was in no electric release conditions, its normally-closed contact is sent sound accompaniment C into TV loudspeaker Y1, use the loudspeaker playback, when W was closed, J got electric adhesive, the normally opened contact closure, audio signal C sends into 2 ends (C5 is used for the high fdrequency component of filtering audio signal, avoids its interference to remote signal) of L through R4, C4, R3, delivers to 1 end of L through L, deliver to little loudspeaker Y2(of transmitting end or earphone through R1, C2 again), listen to television field frame thereby be implemented in transmitting end with earphone.

The relative prior art of the utility model has following advantage: the one, and remote keying of the present utility model is arranged on bedside cupboard, and the passenger can implement the television set repertoire at berth; The 2nd, multidigit dweller can be in bedside cupboard operation separately; The 3rd, work as some dweller and will have a rest, other dwellers can use earphone, are independent of each other; The 4th, be convenient to management, this device has facilitation to the class that improves the hotel, hotel.

The accompanying drawing drawing is described as follows:

Fig. 1 is the utility model front view.

Fig. 2 is the utility model keying line structure chart.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to accompanying drawing 1, the utility model is made up of colour TV (1), coaxial cable (2), bedside cupboard (3), earphone jack (4), remote keying (5), switch (6), in bedside cupboard (3) lining the keying line structure is set, remote keying (5) is set above its front, in button (5) lower end earphone jack (4) is set, both sides are provided with switch (6), finish various signal transmission by coaxial cable (2), realized switching, can listen to earphone at transmitting end and look sound accompaniment at transmitting end remote-controlled television set and control loudspeaker and earphone.

With reference to accompanying drawing 2, the utility model keying line structure is that the remote signal that TV remote controller A sends is taken out from infrared transmission level transistor collector through capacitor C 1(, and infrared transmission diode can replace with resistance) send into coaxial electrical

Claims

1, a kind of wire controlled television set and TV Full remote controlled bedside cupboard, it is characterized in that forming by bedside cupboard (3), earphone jack (4), remote keying (5), switch (6), coaxial cable (2), in bedside cupboard (3) lining the keying line structure is set, earphone jack (4), remote keying (5), switch (6) are set above its front, finish various signal transmission by coaxial cable (2), realized switching, can listen to earphone at transmitting end and look sound accompaniment at transmitting terminal remote-controlled television set and control loudspeaker and earphone.

2, wire controlled television set according to claim 1 and TV Full remote controlled bedside cupboard, it is characterized in that this keying line structure is that the remote signal that TV remote controller A sends is taken out from infrared transmission level transistor collector through capacitor C 1(, infrared transmission diode can replace with resistance) (R1 is a build-out resistor to send into 1 end of coaxial cable L, for the approximate short circuit of remote signal C2) be transferred to 2 ends of L through L, and in capacitor C 3 is coupled to TV remote-control receiving box B the negative pole of infrared receiving diode, thereby (R3 is the cable output end build-out resistor to finish straighforward operation, capacitor C 4, C5 is to the also approximate short circuit of remote signal) switch W is in order to adhesive and the release of control relay J, when W disconnects, J is in no electric release conditions, its normally-closed contact is sent sound accompaniment C into TV loudspeaker Y1, use the loudspeaker playback, when W is closed, J gets electric adhesive, the normally opened contact closure, audio signal C is through R4, C4, R3 sends into 2 ends of L, and (C5 is used for the high fdrequency component of filtering audio signal, avoid its interference) to remote signal, deliver to 1 end of L through L, again through R1, C2 delivers to little loudspeaker Y2(of transmitting end or earphone), listen to television field frame thereby be implemented in transmitting end with earphone.
