Abstract
The utility model discloses a dual-mode resonance portable sound box including a casing, a resonance control circuit arranged in the casing, and a resonance sounder connected in the resonance control circuit. The dual-mode resonance portable sound box is improved in that a speaker control circuit and a speaker connected in the speaker control circuit are arranged in the casing, and the resonance control circuit or the speaker control circuit is provided with a switch circuit for controlling the on and off of the circuit, on which the switch circuit is arranged. The dual-mode resonance portable sound box uses the switch circuit connected on the resonance control circuit or the speaker control circuit to control the switching of the resonance sound box between a single sounding mode and a duel sounding mode, namely, to control the on and off of the circuit, on which the switch circuit is arranged; and the switch circuit further controls the sounding of the speaker or the synchronous sounding of the speaker and the resonance sounder, or controls the sounding of the resonance sounder or the synchronous sounding of the speaker and the resonance sounder. Therefore, when the sound box plays a song in different pitches, the two sounding modes can be freely selected based on the different pitches, thereby bringing users better experiences.

Along with the birth of resonance speaker, sound equipment that resonance speaker and loudspeaker are combined has also appearred in the prior art, and this sound equipment has the characteristics such as high pitch, bass effect is good, range is large; Yet, still there is certain deficiency in the combination of existing resonance speaker and conventional loudspeakers, resonance speaker and conventional loudspeakers can only synchronous cants, can not add between the conventional loudspeakers synchronous cant at conventional loudspeakers sounding (or resonance sounding device) and resonance speaker and switch, in high pitch song and bass song, can't find best use pattern.
[summary of the invention]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of double mode Portable resonant sound box is provided.This sound equipment can pass through the independent sounding of loudspeaker, also can be convenient to the user when different high pitch songs and bass playback of songs by loudspeaker and the dual sounding of resonance sounding device, selects different sounding patterns, so that the better effects if of music.
The technical solution of the utility model is achieved in that a kind of double mode Portable resonant sound box, and it comprises housing and is arranged at housing internal resonance control circuit and is connected in resonance sounding device in the resonance control circuit; Its improvement is: described housing inside trumpet control circuit and be connected in loudspeaker in the horn control circuit arranges a switching circuit that is used for its place connecting and disconnecting of the circuit of control in described resonance control circuit or the horn control circuit.
Described switching circuit is arranged in the resonance control circuit; Described resonance control circuit comprises audio frequency input selection circuit, the first high-pass filtering circuit, low-pass filter circuit and resonance power amplifier; Wherein, described the first high-pass filtering circuit input is connected in the output of audio frequency input selection circuit, the output of the first high-pass filtering circuit is connected in the input of low-pass filter circuit, and the output of described low-pass filter circuit is connected to the input of switching circuit; The output of switching circuit is connected in the input of resonance power amplifier.
Described horn control circuit comprises the second high-pass filtering circuit and loudspeaker power amplifier, and the input of described the second high-pass filtering circuit is connected in the output of audio frequency input selection circuit, and the output of the second high-pass filtering circuit is connected in the input of loudspeaker power amplifier.
The output of described switching circuit also is connected in the input of described loudspeaker power amplifier.
The beneficial effects of the utility model are: the utility model combines the resonance sounding device with loudspeaker, by the switching circuit that connects on resonance control circuit or the horn control circuit, control the switching of this resonance speaker between single sounding pattern and dual sounding pattern, namely control the break-make of its place circuit by switching circuit, and then control sound horn or loudspeaker and resonance acoustical generator synchronous cant, or be resonance sounding device sounding or loudspeaker and resonance acoustical generator synchronous cant; Thus, when playing the different song of high bass, can freely select above-mentioned two kinds of sounding patterns according to the different of high bass, bring the user with this and better experience.
[description of drawings]
