Abstract
The utility model relates to a tenor-bass loudspeaker, comprising a frame, a surface vibrating membrane connected with the frame, a voice coil rack fixed to the vibrating membrane, a voice coil suspension fixed to the voice coil rack, a magnetizer positioned at the back part of a loudspeaker and an annular magnet fixed to the magnetizer. The voice coil rack is in a horn shape, and the upper end of the voice coil rack is provided with a ring support having a V-shaped cross section. The lower part of the central part of the vibrating membrane is provided with a damping column fixed to the top part of the magnetizer, the upper end of the damping column contacts with the central part of the vibrating membrane, and the damping column is provided with an elastic buffer ring section. The surface of the v-shaped ring support at the upper end of the voice coil rack is provided with holes, or the surface of the inner ring and the outer ring of the V-shaped ring support at the upper end of the voice coil rack is a discontinuous annular surface. Via the change of the shape and the structure of the voice coil rack of the tenor-bass loudspeaker and the addition of the damping column, the tenor density of the tenor-bass loudspeaker is raised, and the tenor is sounded fully. The tenor-bass loudspeaker has novel and reasonable structural design.
Description
Technical field
The utility model relates to loud speaker, is specially a kind of medium and low spectrum loudspeaker.
Background technology
Existing medium and low spectrum loudspeaker comprise 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 loud speaker rear portion magnetic conductor, with the fixing ringshaped magnet of magnetic conductor.The sound ring frame of existing medium and low spectrum loudspeaker is cylindric, its main support is at the middle part of vibrating diaphragm, limited with the contact area of vibrating diaphragm, cause vibrating diaphragm intermediate frequency playback time 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, the middle tonal density that causes having now medium and low spectrum loudspeaker is lower, middle pitch is not full.
Summary of the invention
The utility model solves existing medium and low spectrum loudspeaker because of the very unreasonable problem that middle tonal density is lower, middle pitch is not full that causes of sound ring frame structure, and a kind of improved medium and low spectrum loudspeaker is provided.
The utility model is to adopt following technical scheme to realize: medium and low spectrum loudspeaker, comprise 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 loud speaker rear portion magnetic conductor, with the fixing ringshaped magnet of magnetic conductor, sound ring frame is horn-like, and is 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 vibrating diaphragm, the vibration of whole vibrating diaphragm each several part is tending towards synchronously substantially, with this middle tonal density that improves medium and low spectrum loudspeaker, make its middle pitch fuller.
For making the vibrating diaphragm centre further keep vibration synchronously with the vibrating diaphragm other parts, increase the sensitivity that the medium and low spectrum loudspeaker middle pitch is reset, below the vibrating diaphragm centre, be provided with the damping post 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 (spirogyrate or concave shaped).The damping post plays the vibration damping effect to the centre of vibrating diaphragm, further improves the frequency response of loud speaker at the middle pitch frequency band.
The utility model is by the shape and the structure of change sound ring frame, and the damping post of further setting up, and the middle tonal density of this medium and low spectrum loudspeaker is improved, and the middle pitch of sending out has more full weight.Its structural design novelty, reasonable.

Embodiment
Medium and low spectrum loudspeaker, comprise basin frame 1, the surperficial vibrating diaphragm 2 that is connected with the basin frame, with the fixing sound ring frame 3 of vibrating diaphragm, with fixing voice coil loudspeaker voice coil 7 and the centring disk 10 of sound ring frame, be positioned at the loud speaker rear portion magnetic conductor 9, with the fixing ringshaped magnet 8 of magnetic conductor, sound ring frame is horn-like, and is provided with the ring support of cross section for " V " shape in the upper end of sound ring frame.
Below vibrating diaphragm 2 centres, be provided with lower end and the damping post 4 that magnetic conductor 9 tops are fixed, 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.
Stretch out outside the vibrating diaphragm at the top of damping post 4.Like this, the effect of phase place awl also can be played in the top of damping post, helps further improving the tonequality of medium and low spectrum loudspeaker.
Have hole 12 on the inside and outside circle surface of end section for the ring support of " V " shape on the sound ring frame,, produce the high frequency standing wave when preventing the sound ring frame vibration to reduce the reflective surface area of sound ring frame surface to 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.
