Abstract

The utility model belongs to a TV player, which solves the problem that: the existing TV only can be used for broadcasting TV programs in spots, once the TV is opened, the sound is unable to simply control, under normal conditions, the sound can also give the interference to people at public places, the useful information broadcasting at public places through TV is limited. The emergency positioning acoustic control playback device for a multi-function broadcasting TV comprises a TV player, the horn circuit of the TV player is connected with two parallel acoustic control switches in series, wherein, one is a delay acoustic control switch with a delay device, a wireless receiving sounder is arranged beside the delay acoustic control switch with the delay device, another one is an alternate acoustic control switch. The utility model is convenient for opening the horn, realizes the positioning and zoning selection to open the horn, and avoids the interference of unconcerned broadcasting to the relevant areas.

Description

The emergent location acoustic control of multi-functional radio and television playing device

Technical field

The utility model belongs to the radio and television playing device.

Background technology

Existing television set is mainly used in the broadcast TV programme, if place it in the public place, can only play TV programme constantly.For public places such as public passage in building and halls, place some television sets, can be convenient for people to watch and hear the programme content of playing in the TV.When playing some public good programs at the public place in the TV, propagate as public good, weather forecast, fire alarm, cut off the water and electricity supply, traffic, flight forecast etc., and when some important announcements of government and accident, often can be convenient for people to activity outside, be convenient to people and deal carefully with problem according to see situation about hearing.But because that in a single day television set is opened is uncontrollable, under the situation that no abnormal situation takes place, particularly its sound can cause interference to the people in public places, makes to utilize used as television some are restricted for the useful information in public place in issue.

Goal of the invention

The purpose of this utility model is to provide a kind of and controlled by the user and the emergent location acoustic control of the multi-functional radio and television playing device of control centre's control.

For realizing the purpose of this utility model, the emergent location acoustic control of described multi-functional radio and television playing device, comprise televisor, in the loudspeaker loop of televisor, be serially connected with the audio-switch of two parallel connections, one of them is the time-delay audio-switch that has time-delay mechanism, described wireless receiving acoustical generator is arranged on by the time-delay audio-switch that has time-delay mechanism, and another is for replacing audio-switch.

Owing in the loudspeaker loop of televisor, be serially connected with two audio-switches, televisor is other sounds when the public walks to, as clap palm, then alternately audio-switch is subjected to external voice signal and opens, the loudspeaker of televisor are connected, before televisor, not only image can be seen, and sound can be heard.When the public does not want to listen content in the TV, can sound again, as clapping palm again, the loudspeaker of televisor disconnect, have only image in the fluorescent screen this moment, like this can not can produce noise in corridor or hall, with rest, the work that influences other people, but the image content in the fluorescent screen continues playing, and is convenient to pass by herein people and passes by and watch the content of broadcasting before the televisor.When it need hear sound, can be undertaken by operating as previously mentioned.When having accident to take place in the society, as seize the hostage on both sides by the arms, when terrorist incidents etc. influence the major issue of social stability, control department, can send by the wireless transmission center as public security organ and to control signal to the wireless receiving acoustical generator, make the wireless receiving acoustical generator receive that signal produces sound, the time-delay audio-switch that has time-delay mechanism is opened, allow the loudspeaker of televisor connect by force, allow the public hear the sound report of accident, so that the public takes measures, reduce unnecessary loss and injury as far as possible, treat after the incident.The wireless transmission center is sent and is controlled signal to the wireless receiving acoustical generator, make the wireless receiving acoustical generator receive that signal does not produce sound, through time-delay after a while, the time-delay audio-switch that has time-delay mechanism disconnects, the loudspeaker loop of televisor is disconnected, and televisor had only image and did not have sound this moment.

Description of drawings

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model.

The circuit theory diagrams that Fig. 2 is.

Embodiment:

As shown in FIG., the emergent location acoustic control of the multi-functional radio and television described in present embodiment playing device comprises televisor 1, the loudspeaker 2 of televisor 1, and audio-switch 3 triggers acoustical generator 4, sealing blimp 5.One of them audio-switch 3 is for having the time-delay audio-switch of time-delay mechanism, this time-delay audio-switch that has time-delay mechanism is exactly the audio-switch that generally uses in the present dwelling house corridor, when just the pedestrian goes near the stair light, by patting hand, the generation sound of perhaps stamping one's foot is opened corridor lamp.When sound stops after time-delay after a while, this switch just can disconnect, and corridor lamp is closed.Another audio-switch 3 is audio-switch alternately, and this switch was opened during sounding in the first time, closes again during sounding for the second time, and sounding is opened again once more, and then sounding disconnects again, so alternately break-make.

Televisor can be the television set of selling on the market at present, as long as disconnect in loudspeaker wiring place of television set, gets final product at audio-switch that has time-delay mechanism of its gap serial connection.Described triggering acoustical generator 4 can be a landline telephone, also can be the wireless receiving acoustical generator.As landline telephone, can dial relevant landline telephone by telecommunications, make it connect sounding, carry out switch control.Described wireless receiving acoustical generator is a broadcast receiver, at this moment, as long as the radio station provides a special channel as control centre, sounding not under the normal condition at ordinary times, in case abnormal conditions appear, as terrorist incident such as blast, the special channel in the radio station signal of sounding, the audio-switch that has a time-delay mechanism is sensed sound and is opened, and the existing image of the emergent location acoustic control of multi-functional radio and television playing device broadcasts has sound to broadcast again, and can be opened by the centralized and unified control by force of control centre.

When the wireless receiving acoustical generator is radiophone, when diverse location is provided with the phone of jack per station, be convenient to location control unlatching by force, make irrelevant area according to the unlatching of just controlling sound by the user according to normal situation, relevant area is then sent corresponding telephone number by control centre and is made the telephone set sounding that is in this area, avoids irrelevant area to hear by force with its irrelevant incident report and disturbs its normal live and work.

Described wireless receiving acoustical generator is a radio pager, positions subregion by the radio call transmitting station and selects the unlatching loudspeaker to concentrate positioning control.
