Abstract
The utility model relates to a coaxial loudspeaker. It contains the basin frame, the surface vibrating diaphragm of being connected with the basin frame, the voice coil frame fixed with the vibrating diaphragm, voice coil loudspeaker voice coil and centering support piece fixed with the voice coil loudspeaker voice coil, be located the magnetizer that the speaker rear portion comprises bottom magnetic conduction board and the bellied magnetic conduction post in magnetic conduction board middle part, be fixed with high pitch centering support piece in the magnetic conduction post upper end of magnetizer, be fixed with high pitch voice coil loudspeaker voice coil on the high pitch centering support piece, the lower part of high pitch voice coil loudspeaker voice coil frame is fixed with the high pitch voice coil loudspeaker voice coil, upper portion is fixed with the pointed arch high pitch vibrating diaphragm, be equipped with the top contact of upper end and high pitch vibrating diaphragm in the high pitch vibrating diaphragm, the fixed support column. The support column is provided with a buffer structure or a buffer device, namely an elastic buffer ring segment on the support column or an elastic buffer cushion under the support column. Compared with the existing coaxial loudspeaker, the coaxial loudspeaker of the utility model has higher high-frequency signal reproduction sensitivity and larger bandwidth range of reproduced signals; the sound playing effect is better.
Description
Technical field
The utility model relates to loud speaker, is specially a kind of coaxial loudspeaker.
Background technology
Existing coaxial loudspeaker comprises basin frame, the surperficial vibrating diaphragm that is connected with the basin frame, with the fixing sound ring frame of vibrating diaphragm, with fixing voice coil loudspeaker voice coil and the centring disk of sound ring frame, be positioned at the magnetic conductor that the conducting magnetic column by bottom magnetic conductive board and magnetic conductive board middle part projection at loud speaker rear portion constitutes, conducting magnetic column upper end at magnetic conductor is fixed with the high pitch centring disk, be fixed with the high pitch sound ring frame on the high pitch centring disk, the bottom of high pitch sound ring frame is fixed with the high pitch voice coil loudspeaker voice coil, top is fixed with the Gothic arch tweeters diaphragms.About high frequency limit, the phase place of its vibration is opposite with the other parts of tweeters diaphragms, causes the decline of high-frequency signal playback sensitivity, has compressed the bandwidth of coaxial loudspeaker replay signal near the top of tweeters diaphragms.
Summary of the invention
The utility model solves the existing problem that coaxial loudspeaker high-frequency signal playback sensitivity is lower, the replay signal bandwidth is restricted, and a kind of coaxial loudspeaker that improves structure that has is provided.
The utility model is to adopt following technical scheme to realize: coaxial loudspeaker, comprise the basin frame, the surperficial vibrating diaphragm that is connected with the basin frame, with the fixing sound ring frame of vibrating diaphragm, with fixing voice coil loudspeaker voice coil and the centring disk of sound ring frame, be positioned at the magnetic conductor that the conducting magnetic column by bottom magnetic conductive board and magnetic conductive board middle part projection at loud speaker rear portion constitutes, conducting magnetic column upper end at magnetic conductor is fixed with the high pitch centring disk, be fixed with the high pitch sound ring frame on the high pitch centring disk, the bottom of high pitch sound ring frame is fixed with the high pitch voice coil loudspeaker voice coil, top is fixed with the Gothic arch tweeters diaphragms, is provided with the upper end and contacts with the top of tweeters diaphragms in tweeters diaphragms, the support column that the conducting magnetic column of lower end and magnetic conductor is fixing.Support column obtains the location near making the top of tweeters diaphragms, be not participate in vibration near the top, near the opposite problem that high-frequency signal playback sensitivity is low, the replay signal bandwidth is restricted that is caused of vibration phase when solving high frequency limit because the top with other parts with this.
To locate fully near the tweeters diaphragms top, under the strong signal of large amplitude, make tweeters diaphragms produce distortion easily, make the work of coaxial loudspeaker very unreliable.For making coaxial loudspeaker more reasonable structure, work after the improvement more reliable, support column is provided with buffer structure or buffer unit.Elastic buffer ring section (the elastic buffer ring section of convex or concave formula) is set on support column.Elastic buffer ring section makes support column have certain elastic buffer up and down, make near the top of tweeters diaphragms and to participate in vibration among a small circle but its vibration obviously is subjected to damping again, thereby overcome near the yielding deficiency of tweeters diaphragms under the strong signal of the large amplitude that brought of the location fully tweeters diaphragms top, further improve coaxial loudspeaker described in the utility model.
What be provided with on support column dashes structure or buffer unit also, is fixed with elastic buffering pad (as rubber blanket, plastic foam pad etc.) between support column and conducting magnetic column top.It similarly can play the effect to the support column elastic buffer.
Coaxial loudspeaker described in the utility model is compared with existing coaxial loudspeaker, and the playback sensitivity of high-frequency signal is higher, and the bandwidth range of replay signal is bigger; Its playback effect is better.
