A damping column is arranged below the center part of the mushroom head vibrating diaphragm, the lower end of the damping column is fixed with the top of the magnetizer, and the upper end of the damping column is contacted with the center part of the vibrating diaphragm, and an elastic buffering ring section is arranged on the damping column. The utility model adds the vibrating diaphragm area on the basis of the prior mushroom high pitch loudspeaker, so that the audio frequency band is strengthened; the upper limit of high-pitch frequency of the mushroom head high-pitch loudspeaker is improved by changing the shape and the structure of the voice coil former. The sound quality of the mushroom head high-pitched loudspeaker is obviously improved.
Description
Technical field
The utility model relates to loud speaker, is specially mushroom head height sound loud speaker.
Background technology
Existing mushroom head height sound loud speaker comprises the base that has vertical support anchor ring, be fixed in magnetic conductor in the base, by the fixing sound ring frame of buffer edge and base, be fixed in the voice coil loudspeaker voice coil of sound ring frame bottom and be coated on sound ring frame and mushroom the vibrating diaphragm bonding outward with sound ring frame.Existing mushroom head height sound loud speaker has only a mushroom vibrating diaphragm thermal vibration sounding, and its middle pitch reproduces relative deficiency; The sound ring frame of its sound loud speaker is cylindric simultaneously, its main support is in the middle and upper part of a mushroom vibrating diaphragm, limited with the contact area of vibrating diaphragm, cause vibrating diaphragm easily to produce and cut apart vibration---promptly near and away from the phase place inconsistent (vibration of vibrating diaphragm each several part is asynchronous) of the vibrating diaphragm vibration of sound ring frame, cause the high pitch upper limiting frequency decline of loud speaker.
Summary of the invention
The utility model solves existing mushroom head height sound loud speaker middle pitch and reproduces relative deficiency, the sound ring frame shape and structure is not very reasonable, the inconsistent restricted problem of high pitch upper limiting frequency that causes of vibrating diaphragm each several part vibration phase, and a kind of improved mushroom head height sound loud speaker is provided.
The utility model is to adopt following technical scheme to realize: mushroom head height sound loud speaker, comprise base, be fixed in magnetic conductor in the base, with the fixing sound ring frame of vibrating diaphragm, be fixed in the voice coil loudspeaker voice coil of sound ring frame bottom and be coated on outer and mushroom the vibrating diaphragm bonding of sound ring frame with sound ring frame, be provided with the anchor ring vibrating diaphragm between a mushroom vibrating diaphragm and the base, the vertical support anchor ring that is about to existing mushroom head height sound loud speaker base changes vibrating diaphragm into.The anchor ring vibrating diaphragm is mainly sent out middle pitch, therefore, the middle pitch frequency band of mushroom head height sound loud speaker is strengthened, and the tonequality of mushroom head height sound loud speaker is improved.
Be provided with the ring support of cross section for " V " shape in the upper end of sound ring frame.By changing the shape and the structure of sound ring frame, increased contacting of sound ring frame and mushroom vibrating diaphragm, make the vibration of a whole mushroom vibrating diaphragm each several part be tending towards synchronous substantially, solve the restricted problem of the mushroom head height sound loud speaker treble frequency upper limit with this, the treble frequency upper limit of mushroom head height sound loud speaker is improved.
The utility model has increased the vibrating diaphragm zone on the basis of existing mushroom head height sound loud speaker, making wherein, voiced band is strengthened; By shape and the structure that changes sound ring frame the treble frequency upper limit of mushroom head height sound loud speaker is improved.The tonequality of mushroom head height sound loud speaker is significantly improved.

Embodiment
Mushroom head height sound loud speaker, comprise base 1, be fixed in magnetic conductor 2 in the base, with the fixing sound ring frame 3 of vibrating diaphragm, be fixed in the voice coil loudspeaker voice coil 4 of sound ring frame bottom and be coated on outer and mushroom the vibrating diaphragm 5 bonding of sound ring frame with sound ring frame, be provided with anchor ring vibrating diaphragm 6 between a mushroom vibrating diaphragm and the base.Anchor ring vibrating diaphragm 6 upper ends are connected (or making one) with a mushroom vibrating diaphragm, and the lower end is fixed by buffer edge 7 and base.
Be provided with the ring support 8 of cross section for " V " shape in the upper end of sound ring frame.
Have hole 12 on the inside and outside circle surface that end section supports for the ring of " V " shape on the sound ring frame, produce the high frequency standing wave when preventing the sound ring frame vibration, reduce the reflective surface area of sound ring frame surface sound wave.
End section is the ring surface of inside and outside circle surface for being interrupted of the ring support of " V " shape on the sound ring frame, and promptly inside and outside circle surface is discrete ring surface.Like this, can reduce the reflective surface area of sound ring frame surface more fully, produce the high frequency standing wave when preventing the sound ring frame vibration sound wave.
End section is the relative (see figure 4) of discontinuities on the ring surface that is interrupted of inside and outside circle that the ring of " V " shape supports on the sound ring frame.
Discontinuities on the ring surface that the inside and outside circle that end section supports for the ring of " V " shape on the sound ring frame the is interrupted (see figure 5) that interlaces.
End section makes the middle and lower part of reservation face become shaft-like (see figure 6) for the both sides at the following middle part of the reservation face on the ring surface of the inside and outside circle interruption of the ring support of " V " shape are bent upwards on the sound ring frame.So not only can increase the support strength of reservation face, and further reduce the reflective surface area of sound ring frame surface sound wave.
For making a mushroom vibrating diaphragm centre further keep vibration synchronously with the vibrating diaphragm other parts, increase the sensitivity that the high pitch upper limiting frequency is reset, below a mushroom vibrating diaphragm centre, be provided with the damping post 10 that the lower end is fixed with the magnetic conductor top, the upper end contacts with the vibrating diaphragm centre, and on the damping post, be provided with elastic buffer ring section 11.This elastic buffer ring section can be spirogyrate or concave shaped.The damping post plays the vibration damping effect to the centre of a mushroom vibrating diaphragm, further improves the frequency response of loud speaker in the treble frequency section.
