Abstract
The invention discloses a kind of speaker for touching start, including sound box bodies, sound box bodies are equipped with circuit system, touch switch circuit, and circuit system is electrically connected by supply lines with city, and touch switch circuit includes：Close to switch, relay, photo-coupler, the output terminal close to switch is concatenated with the input terminal of photo-coupler, and the output terminal of photo-coupler is concatenated with the input circuit of relay, and the output loop of relay is concatenated with supply lines.When user touches the close switch, the photo-coupler responds and turns on its emitter and collector, and the relay is attracted, and turns on supply lines, and then turns on alternating current and circuit system, so that speaker start.Due to not directly controlling the conducting of alternating current and circuit system close to switch, the induced electromotive force that circuit system produces can't be applied directly to close on switch, spark will not be being produced close on switch, therefore the user of start will not be given to cause danger.The speaker can be applied to daily life.
Description
Technical field
The present invention relates to sound technique field, more particularly to a kind of speaker for touching start.
Background technology
Existing speaker is equipped with circuit system, and the circuit system is used for realization the various electrical functions of sound box bodies, described
Circuit system is electrically connected by supply lines with city, and the supply lines is switched equipped with ship type, when user needs to start shooting to speaker,
Only need, by type switch of delaying unloading a ship, supply lines to be turned on, so that turning circuit system and alternating current.
But since the circuit system of speaker is perceptual system, speaker start can produce powerful induced electricity in supply lines
Kinetic potential, the induced electromotive force are acted in ship type switch ends, easily so that ship type switch is impacted, produce spark, this
Spark is applied on ship type switch, easily causes danger to user.
The content of the invention
The purpose that the present invention solves is：A kind of speaker for touching start is provided, avoids user from being made in start because of spark
Into danger.
The present invention solve its technical problem solution be：A kind of speaker for touching start, including sound box bodies, the sound
Babinet is equipped with circuit system, and the circuit system is electrically connected by supply lines with city, and the sound box bodies are additionally provided with soft-touch control electricity
Road, the touch switch circuit include：Close to switch, relay, photo-coupler, the output terminal close to switch and the light
The input terminal concatenation of coupler, the output terminal of the photo-coupler are concatenated with the input circuit of the relay, the relay
Output loop concatenated with the supply lines.
Further, it is described to be switched close to switch for infrared-type is close.
Further, the model TPL521 of the photo-coupler.
The beneficial effects of the invention are as follows：When user touches the close switch, the photo-coupler responds and turns on it
Emitter and collector, the relay are attracted, and turn on supply lines, and then turn on alternating current and circuit system, so that speaker
Start.Due to not directly controlling the conducting of alternating current and circuit system close to switch, the induction electric that circuit system produces
Gesture can't be applied directly to close on switch, spark will not be being produced close on switch, therefore will not give the user of start
Cause danger.
Brief description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is the part of the embodiment of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also obtain other designs according to these attached drawings
Scheme and attached drawing.
Fig. 1 is the connection relationship diagram of touch switch circuit.
Embodiment
Carried out clearly below with reference to the technique effect of the design of embodiment and attached drawing to the present invention, concrete structure and generation
Chu, be fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art is not paying
The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
All connection/connection relations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to form more preferably draw bail.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Embodiment 1, with reference to figure 1, a kind of speaker for touching start, including sound box bodies, the sound box bodies are equipped with soft-touch control
Circuit, circuit system 5, the circuit system 5 are used for realization the various electrical functions of sound box bodies, and the circuit system 5 passes through confession
Electric wire 51 is connected with alternating current 52, and the touch switch circuit includes：Close to switch 1, relay 3, photo-coupler 2, decompression filtering
Circuit 4, described to be switched close to switch 1 for infrared-type is close, the model TPL521 of the photo-coupler 2, the decompression filter
The input terminal of wave circuit 4 is connected with alternating current 52, and output terminal is connected with described close to switch 1, for providing direct current to approach switch 1
Voltage, it is described close to switch 1 output terminal concatenated with the input terminal of the photo-coupler 2, the emitter of the photo-coupler 2 and
The input circuit concatenation of the relay 3, the collector of the photo-coupler 2 and the output terminal of the decompression filter circuit connect
Connect, the output loop of the relay 3 is concatenated with the supply lines 51.
It is described to be responded close to the output high level of switch 1, the photo-coupler 2 when user touches the close switch 1
And its emitter and collector are turned on, the relay 3 is attracted, and turns on supply lines 51, and then turn on alternating current 52 and circuit system
5, so that speaker is started shooting.Due to not directly controlling the conducting of alternating current 52 and circuit system 5 close to switch 1, circuit
The induced electromotive force that system 5 produces can't be applied directly to close on switch 1, will not produce spark close on switch 1,
Therefore the user of start will not be given to cause danger.
The better embodiment of the present invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent modifications on the premise of without prejudice to spirit of the invention or replace
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
