Abstract
The utility model discloses a high-power switching circuit for two-route switching, comprising a passive input terminal and a frequency dividing circuit. The passive input terminal is connected to the frequency dividing circuit. The high-power switching circuit also comprises an active input terminal and a shifting switch connected to a loudspeaker. The output terminal of the frequency dividing circuit is connected to one input terminal of the shifting switch, and the active input terminal is connected to the other input terminal of the shifting switch. The high-power switching circuit for two-route switching enables a passive sound box to be directly connected to an active sound box through the high-power switching circuit.
Description
Technical field
The utility model relates to acoustic product manufacturing technology field, is specifically a kind of high power two-way switching switch circuit.
Background technology
Audio amplifier divides active audio amplifier and passive loudspeaker box at present.Wherein, active audio amplifier does not need to join external power amplifier again, carries more for convenience, and is high but its cost ratio passive loudspeaker box is wanted.Passive loudspeaker box need to be joined external power amplifier again, carries inconvenience, but its price is lower.
When audio amplifier used, major part was to be equipped with plural audio amplifier to work simultaneously, if all use active audio amplifier, cost can be higher, if all use passive loudspeaker box, carries more inconvenient.Therefore, demand urgently for these reasons needing a kind of high power two-way switching switch circuit, make passive loudspeaker box directly to be connected with active audio amplifier by this circuit, to address the above problem.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and a kind of high power two-way switching switch circuit is provided, and makes passive loudspeaker box directly to be connected with active audio amplifier by this circuit.
The technical solution of the utility model is, a kind of high power two-way switching switch circuit is provided, comprise passive input port and frequency dividing circuit, described passive input port is connected with frequency dividing circuit, described high power two-way switching switch circuit comprises active input port and the diverter switch that is connected with loud speaker, the output of described frequency dividing circuit is connected with an input of diverter switch, and described active input port is connected with another input of diverter switch.
Described passive input port is the two passive input ports of passage; Described active input port is the active input port of four-way; Described diverter switch is the four-way diverter switch.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model high power two-way switching switch circuit is arranged in passive loudspeaker box, and passive input port can be connected with power amplifier use, and active input port can directly connect the signal of active audio amplifier output.By being used in conjunction with of passive loudspeaker box and active audio amplifier, not only having saved use cost, and carried more like this.
