Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of checkout gear of loudspeaker type, can detect the loudspeaker type of loudspeaker.Below be described in detail respectively.
Please refer to Fig. 1, it is the structural representation of the checkout gear of a kind of loudspeaker type that the utility model embodiment provides, the checkout gear of described loudspeaker type can comprise loudspeaker, voltage detecting point and controller, wherein loudspeaker can comprise the first leakage copper, the second leakage copper and default medium, first leakage copper and second leaks between copper and separates by presetting medium, first leaks copper is connected with power supply, and second leaks copper is connected to ground.
Controller, for determining the voltage status of voltage detecting point, according to voltage status, detect the loudspeaker type of loudspeaker, controller leaks copper by voltage detecting point and first and is connected.The voltage status of voltage detecting point can comprise high-voltage state or low-voltage state.
In an alternative embodiment, the checkout gear of loudspeaker type can also comprise resistance, wherein:
One end of resistance is connected with power supply, and the other end and first of resistance leaks copper and is connected.
Resistance in the utility model embodiment, in order to protective circuit, when current is excessive, makes the wire in resistance produce high temperature and fuse, causes power supply and first to leak copper and open a way, play the effect of fuse.
In an alternative embodiment, controller is according to voltage status, and the concrete mode detecting the loudspeaker type of loudspeaker is:
When voltage status is low-voltage state, controller determines that the first leakage copper and second leaks copper conducting, determines that default medium is conducting medium, and the loudspeaker type detecting loudspeaker is the first loudspeaker type.
Further alternative, conducting medium can comprise iron, copper, graphite or conductive sponge etc.
In an alternative embodiment, controller is according to voltage status, and the concrete mode detecting the loudspeaker type of loudspeaker is:
When voltage status is high-voltage state, controller determines that the first leakage copper and second leaks copper and disconnects, and determines that default medium is dielectric, detects that the loudspeaker type of loudspeaker is the second loudspeaker type.
Further alternative, dielectric can comprise plastics, rubber, glass or pottery etc.
In an alternative embodiment, controller according to voltage status, detect loudspeaker loudspeaker type after, also for:
Controller obtains audio frequency parameter corresponding to loudspeaker type.
Audio frequency parameter can comprise power output etc., and the power output of the such as loudspeaker of the first loudspeaker type can be 250W, and the power output of the loudspeaker of the second loudspeaker type can be 220W.
Controller, according to audio frequency parameter, amplifies preset audio signal.
Controller according to audio frequency parameter, can amplify preset audio signal.Such as, the blend proportion of loudspeaker effect can calculate according to 1:1.3.When the power output of loudspeaker is 250W, the power output through the audio signal of amplifying can be 250*1.3=325W.When the power output of loudspeaker is 220W, the power output through the audio signal of amplifying can be 220*1.3=286W.
Audio signal through amplifying is sent to described loudspeaker by controller.
Loudspeaker, for playing the audio signal through amplifying.
