Abstract
The utility model provides a remote controller with an accompanying sound earphone. The utility model consists of a remote controller shell, and a remote controlled signal emitting and controlling circuit. The utility model is characterized in that an accompanying sound signal receiving circuit and an accompanying sound signal amplifying circuit and an earphone output interface are simultaneously arranged. The optimized proposal is that an emitting circuit on an audio device is provided with a switch, the switch and the original volume switch are arranged together; an accompanying sound volume adjuster is arranged on the remote controller simultaneously, and the adjuster can be led out from the amplifying circuit. The utility model integrates the remote controller in the prior art and the accompanying sound receiver, the accompanying sound on the devices such as the TV set and the like can be emitted not through sound boxes but through wireless electric signals, after the accompanying sound is received by the accompanying sound receiver, the user can listen through the earphone, and other persons around cannot be influenced. The utility model solves the problem of the disturbance of the audio device of the household electric appliance; and solves the problem of convenient usage; and can reduce the troubles in the caring, the storage, and the usage of the household electric appliance.
Description
Technical field
Utility model relates to a kind of remote controller that has the sound accompaniment earphone, the remote controller that has the sound accompaniment earphone that particularly a kind of television set, VCD, DVD or other stereo sets use.
Technical background is along with growth in the living standard, the popularity rate of various household electrical appliance is more and more higher, be equipped with other multiple stereo sets such as television set, VCD, DVD and large-scale audio amplifier simultaneously in a lot of families, the situation that the same family has two or three television sets is also more and more general.These equipment bring to people happy in, also produced the sound equipment interference, for around other people also may be a kind of noise.For example when two people of the same family watched different channel respectively on two television sets, sound will interfere with each other.Teleview in the time of sleep or reading the same indoor people of having, the interference problem of sound is just more serious.A kind of sound accompaniment recipient has been arranged in the prior art, is the emitter that installs audio signal on stereo sets such as television set additional, and other establishes a sound accompaniment receiving device, and this device is provided with audio signal receiving circuit, amplifying circuit and earphone.Sound accompaniment during use on the equipment such as television set is not emitted by audio amplifier; Only launch, after receiving by aural receiver, listen to for the user by earphone by radio signal, to around other people do not produce any influence.This aural receiver has solved household electrical appliance sound equipment interference problem from principle, but it is very inconvenient during actual the use: as usually to need the user to take remote controller on the other hand, another hand is taken aural receiver, perhaps needs to wear, take off aural receiver and earphone repeatedly on health, and is very loaded down with trivial details.
Summary of the invention
The utility model will improve aural receiver of the prior art, a kind of sound accompaniment receiving system of new construction is provided, this device combines remote controller of the prior art and two kinds of products of aural receiver, give the user with convenient, also can obviously reduce the trouble in keeping, collection and the use of household electrical appliance annex simultaneously.
The scheme that realizes this purpose is: a kind of remote controller that has the sound accompaniment earphone, constitute by remote controller shell and remote signal countdown circuit, and it is characterized in that: be provided with audio signal receiving circuit, audio signal amplifying circuit and headset output interface simultaneously.Need install aural transmitting circuit additional on corresponding stereo set such as television set, DVD during use, the signal of this circuit emission is listened to by earphone after being received, amplify by the receiving circuit on the remote controller.Can be provided with switch in the radiating circuit on the stereo set, prioritization scheme is: this switch can be set together with original volume switch (potentiometer), and when turning off volume, aural transmitting circuit is connected, and begins emission; When opening volume, radiating circuit disconnects, and does not work.The adjusting of remote controller earpiece volume, can adopt two kinds of schemes: one is to use volume on the original stereo set to regulate the output intensity of its audio signal, slightly inconvenience when this scheme is used.Prioritization scheme is: be provided with the audio volume adjuster on the remote controller simultaneously, this adjuster can be drawn (scheme of this programme and above-mentioned " this switch and original volume switch of the radiating circuit on the stereo set are set together " should adopt simultaneously) from amplifying circuit.Earphone interface on the remote controller also can adopt jackswitch, and this switch is arranged between receiving circuit and the power supply.When inserting earphone, receiving circuit work is connected, is started working.
The utility model combines remote controller of the prior art and two kinds of products of aural receiver, and the sound accompaniment during use on the equipment such as television set is not emitted by audio amplifier; Only launch, after receiving by aural receiver, listen to for the user by earphone by radio signal, to around other people do not produce any influence.This programme has solved household electrical appliance sound equipment interference problem, has solved problem easy to use simultaneously, has also reduced simultaneously the trouble in keeping, collection and the use of household electrical appliance annexes significantly.
