Abstract

The utility model provides a high-efficiency full-range loudspeaker, which consists of a front horn structure and a rear bassoon. The high-efficiency full-range loudspeaker comprises a front horn, a rear mask body, a load bearing seat, a horn monomer, at least one control circuit board, an equalizer, a bass resonator, a fixed seat, a first resonance space, a second resonance space, a third resonance space and a fourth resonance space. The front horn comprises a cavity tube arranged in the inner bottom part of the loudspeaker. The load bearing seat comprises a sound conduction cavity. The horn monomer is arranged on the load bearing seat. The equalizer is arranged in the sound conduction cavity of the load bearing seat and used to obstruct and defer the travel of the forward wave of the horn monomer, so as to buffer the soprano effect increment and to balance the alto. The first resonance space, the second resonance space, the third resonance space and the fourth resonance space are communicated with the cavity tube and the bass resonator to form the rear bassoon which has the function of a post amplifier, so as to eliminate the tube sound and amplify the bass resonance, therefore obtaining the effect of full-range play in the narrow and limited space of the loudspeaker.

Description

A kind of high efficiency full-range speaker

Technical field

The utility model relates to a kind of loud speaker, relates in particular to the high efficiency full-range speaker that adopts a kind of preposition bugle structure, rearmounted bassoon to form.

Background technology

Because digitlization MP3, the music of MP4 form, image energy are stored in various storage card, the memory, make and carry facility more, so sound, the image Storage Media of healing and becoming to transferring to main flow, related player kind such as MP3, the MP4 player that makes electronic installation, the mobile phone that can play MP3, MP4 form are greatly in vogue, but because most MP3, MP4 player or mobile phone only can utilize earphone to listen to sound, as desire then must pass through the auxiliary of loud speaker in sound being interspersed among in the space, can be reached.

The audio frequency effect of existing loud speaker such as desire output gamut must be installed in loudspeaker, mediant trumpet and bass horn in one audio amplifier, and install a partial device in described audio amplifier.After receiving a sound source signal by described partial device, earlier sound source signal is separated into high audio part, sound intermediate frequency part and bass partly, more different audio frequency are conducted to corresponding loudspeaker, mediant trumpet and bass horn respectively and output sound.But, owing to be used in the loud speaker that various broadcast machines such as MP3, MP4 or mobile device are adopted, the preferably must meet little, the portative requirement of volume, therefore can't in the small-sized loud speaker confined space of taking of this kind, high, medium and low sound loudspeaker be set, to reach gamut, high efficiency and to have the loud speaker effect that big volume is play at all.

Certainly, existing on the market numerous small-sized loud speakers of taking can be selected for the consumer, and manufacturer is also in the small-sized sound effect of doing one's utmost to promote output on the loud speaker of taking of the confined space, its practice is mainly on the different outer surfaces of the casing of the sound machine of raising one's voice, offer a plurality of spaces for the placement of loudspeaker monomer, can strengthen the range effect with it by most loudspeaker monomers, but actual result is good not as expection, main must cause the volume of loud speaker effectively to dwindle, make to lose the original purpose that to take be convenient to because increase the loudspeaker monomer.

Summary of the invention
