Specific embodiment

In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

Referring to figures 1-3, a kind of source of sound coaxial sound box, including cabinet 1, high-pitched speaker 2 and at least two woofers 3, high-pitched speaker 2 and woofer 3 are set in cabinet 1, and woofer 3 is located at the lower section of high-pitched speaker 2, each woofer 3 centered on the axis 8 of high-pitched speaker circumferentially array distribution.Specifically, referring to fig. 2, since each woofer 3 is with high pitch loudspeaker Circumferentially array distribution centered on axis 8 is fallen on the axis 8 of high-pitched speaker so that the audio of each woofer 3 is integrated, The source of sound of woofer 3 effect coaxial with the source of sound of high-pitched speaker 2 is generated, so that the linear distortion of audio signal is reduced, To improve playing quality, preferable sense of hearing is obtained.Therefore, because the quantity of woofer 3 can be equipped with it is more than one, thus more Conducive to the adjusting of its volume.More specifically, being equipped with digital processing unit or frequency divider in cabinet 1, wherein digital processing unit (Digital Signal Processing) is referred to as DSP.Since digital processing unit or frequency divider have the function of input delay Can, high-pitched speaker 2 and woofer 3 are controlled by digital processing unit or frequency divider, so that high-pitched speaker 2 and woofer 3 Audio falls within A point 7 (referring to fig. 2) simultaneously, i.e., so that the source of sound of this source of sound coaxial sound box by A point 7 like being generated, so that high pitch loudspeaker 2 and woofer 3 audio sync propagate, further reduce the linear distortion of audio signal, that is, further improve and put Sound quality.

Further, woofer 3 is connected with bass bugle 31, and bass bugle 31 and woofer 3 are coaxially disposed, and low Sound bugle 31 is connected to the side on woofer 3 close to high-pitched speaker 2.By the setting of bass bugle 31, so that each bass The audio of loudspeaker 3 preferably concentrates on the axis 8 of high-pitched speaker, further reduces the linear distortion of audio signal.More Body, woofer 3 is inclined relative to horizontal setting.It, will since the size of woofer 3 is bigger relative to high-pitched speaker 2 Woofer 3 is obliquely installed, and not only can reasonably occupy the inner space of cabinet 1, to reduce the size of cabinet 1, simultaneously More conducively the audio of each woofer 3 is concentrated on the axis 8 of high-pitched speaker, to further reduce the line of audio signal Property distortion, that is, further improve playing quality.

Preferably, this source of sound coaxial sound box further includes mediant trumpet 4, mediant trumpet 4 is equipped at least two, mediant trumpet 4 Positioned at the lower section of high-pitched speaker 2, and it is located at the top of woofer 3, each mediant trumpet 4 is centered on the axis 8 of high-pitched speaker Circumferentially array distribution.On the one hand, playing quality can be improved by being provided with mediant trumpet 4；On the other hand, pass through each middle pitch Loudspeaker 4 are the distribution of center circumference array with the axis 8 of high-pitched speaker, so that the audio of each mediant trumpet 4 is integrated to fall within high pitch loudspeaker On axis 8, i.e. the source of sound of generation mediant trumpet 4 effect coaxial with the source of sound of high-pitched speaker 2, to reduce audio signal Linear distortion obtain preferable sense of hearing to improve playing quality.

Further, this source of sound coaxial sound box further includes middle pitch bugle 41, middle pitch bugle 41 be located at each woofer 3 it Between, and the axis 8 of the axis of middle pitch bugle 41 and high-pitched speaker is conllinear.So that the sound of woofer 3 and mediant trumpet 4 Frequency is more compactly gathered on the axis 8 of high-pitched speaker.It is further reduced the linear distortion of audio signal, to improve playback matter Amount, obtains preferable sense of hearing.

Further, high-pitched speaker 2 is located in middle pitch bugle 41, so that high-pitched speaker 2, mediant trumpet 4 and low Sound loudspeaker 3 are arranged more compact, save space, and keep its audio signal undistorted；And make the sufficiently benefit of high-pitched speaker 2 With the effect of middle pitch bugle 41, its audio is combined on the axis 8 of high-pitched speaker.Preferably, middle pitch bugle 41 is equipped with support Frame 5, high-pitched speaker 2 is set on support frame 5, so that high-pitched speaker 2 easily facilitates installation.

Further, interval is formed with sound seam 6 between middle pitch bugle 41 and cabinet 1, sound seam 6 for for sound transmission, from And in the case where the top of cabinet 1 seals, each audio can stitch 6 along sound and reach propagation mouth, and propagating mouth is that this source of sound is coaxial The sound of speaker spreads out of the outlet outside cabinet 1 out of cabinet 1.

Preferably, mediant trumpet 4 is horizontally disposed, and middle pitch bugle 41 is connected on mediant trumpet 4 close to high-pitched speaker 2 Side.Since each mediant trumpet 4 is smaller compared to each woofer 3, it is thus possible to which each middle pitch loudspeaker is horizontally arranged in realization 4, avoid the location conflicts of mediant trumpet 4 Yu woofer 3, thus fully utilize cabinet 1 space, reduce cabinet 1 size.

The source of sound coaxial sound box of the utility model, each woofer 3 circumferentially array centered on the axis 8 of high-pitched speaker Distribution and each mediant trumpet 4 with the axis 8 of high-pitched speaker be center circumference array be distributed so that the audio of each woofer 3 On the integrated axis 8 for falling within high-pitched speaker of audio of mediant trumpet 4, source of sound, the mediant trumpet of woofer 3 can be generated The coaxial effect of the source of sound of 4 source of sound and high-pitched speaker 2, to reduce the linear distortion of audio signal.Therefore, this is practical new Coaxial horn technology (Coaxial horn technology), referred to as CHT are named as to the technological means in type.Wherein, originally Woofer 3, mediant trumpet 4 and the high-pitched speaker 2 of source of sound coaxial sound box produce the coaxial effect of source of sound, due to Horn loudspeaker It is commonly called as high-pitched speaker, thus the technological means for defining the utility model is coaxial horn, i.e., coaxial horn technology.

Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to In the utility model range claimed.
