Abstract
The utility model discloses a coaxial double-frequency loudspeaker. The coaxial double-frequency loudspeaker comprises a high pitch unit and an intermediate pitch unit, wherein the high pitch unit is positioned at a central position, the intermediate pitch unit is positioned at an outer ring of the high pitch unit; the high pitch unit and the intermediate pitch unit form a coaxial structure; and a high pitch annular vibrating diaphragm is disposed in the high pitch unit, and an intermediate pitch annular vibrating diaphragm is disposed in the intermediate pitch unit. Central axes of frequency transmission of high pitch and intermediate pitch are on the same axis, transmission phase fidelity of sound in the high pitch and intermediate pitch ranges is very high, individual positions generating sounds are not easy to mix, and the sounds are clear and transparent, and thus a problem of phase deviation is solved, and confusion of sounds is prevented.
Description
Technical field
The utility model relates to a kind of loud speaker, especially relates to a kind of coaxial loudspeaker.
Background technology
The music playback frequency band of single loud speaker has certain width, usually can't satisfy the so wide scope of people's ear 20～20kHz fully, therefore, existing audio amplifier adopts reset respectively separately frequency range of height, Squawker mostly, synthesize whole music then, to satisfy the needs of music playback.
Yet, voice unit and middle pitch unit are arranged on the panel of audio amplifier owing to plane earth, so it is a point that their sounding center can not overlap, like this, it is just variant that high pitch and middle pitch arrive the distance of listening the hearer, this species diversity can cause phase deviation, thereby influences the correct reduction of acoustic image, causes the confusion of sound.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of phase deviation problem that can solve, the coaxial double-frequency loud speaker of avoiding sound to cause confusion.
To achieve these goals, the utility model adopts following technical scheme:
A kind of coaxial double-frequency loud speaker, comprise voice unit and middle pitch unit, described voice unit is positioned at the center, described middle pitch unit is positioned at the outer shroud of described voice unit, described voice unit and described middle pitch unit constitute coaxial configuration, be provided with high pitch annular vibrating diaphragm in the described voice unit, be provided with middle pitch annular vibrating diaphragm in the described middle pitch unit.
Further, described high pitch annular vibrating diaphragm can be arranged in the described middle pitch annular vibrating diaphragm.
Further, be arranged in the described middle pitch annular vibrating diaphragm described high pitch annular vibrating diaphragm concentric.
Further, the diameter of described middle pitch annular vibrating diaphragm is much larger than the diameter of described high pitch annular vibrating diaphragm.
Further, the middle pitch sound wave of the high pitch sound wave of described voice unit and described middle pitch unit transmits in separate space.
Further, the high pitch sound wave of described voice unit transmits in first chamber.
Further, the middle pitch sound wave of described middle pitch unit transmits in second chamber.
Further, the middle pitch sound wave of the high pitch sound wave of described voice unit and described middle pitch unit remerges the transmission sound wave transmit specific range in separate space after.
Further, the central axis of described high pitch annular vibrating diaphragm and described middle pitch annular vibrating diaphragm is same axis.
Compared with prior art, the axis that the frequency of the utility model high pitch and middle pitch is propagated is same axis, propagation phase fidelity high, middle pitch range sound is high, and the position separately of sounding also is difficult for chaotic, sound is Clear ﹠ Transparent, thereby solved the problem of phase deviation, avoided sound to cause confusion.

Fig. 2 is front schematic view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Fig. 1 and Fig. 2, the utility model has disclosed a kind of coaxial double-frequency loud speaker 1, comprise voice unit 11 and middle pitch unit 12, described voice unit 11 is positioned at the center, described middle pitch unit 12 is positioned at the outer shroud of described voice unit 11, described voice unit 11 and described middle pitch unit 12 constitute coaxial configuration, are provided with high pitch annular vibrating diaphragm 111 in the described voice unit 11, are provided with middle pitch annular vibrating diaphragm 121 in the described middle pitch unit 12.
Described high pitch annular vibrating diaphragm 111 can be arranged in the described middle pitch annular vibrating diaphragm 121.Be arranged in the described middle pitch annular vibrating diaphragm 121 described high pitch annular vibrating diaphragm 111 concentrics.The diameter of described middle pitch annular vibrating diaphragm 121 is much larger than the diameter of described high pitch annular vibrating diaphragm 111.
The middle pitch sound wave of the high pitch sound wave of described voice unit 11 and described middle pitch unit 12 at first transmits in separate space, the high pitch sound wave of described voice unit 11 transmits in first chamber 13, and the middle pitch sound wave of described middle pitch unit 12 transmits in second chamber 14.The middle pitch sound wave of the high pitch sound wave of described voice unit 11 and described middle pitch unit 12 remerges the transmission sound wave at the 3rd chamber 15 transmit specific range in separate space after.
The axis that the frequency of the utility model high pitch and middle pitch is propagated is same axis, propagation phase fidelity high, middle pitch range sound is high, and the position separately of sounding is also difficult chaotic, and sound is Clear ﹠ Transparent, thereby solved the problem of phase deviation, avoided sound to cause confusion.
Abovely in conjunction with most preferred embodiment the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains various modification, equivalent combinations of carrying out according to essence of the present utility model.
