Abstract
The utility model discloses an electric loudspeaker, comprising a support, a voice coil, a centering disk which has elasticity and can vibrate up and down and a magnetic loop assembly, wherein the voice coil is suspended in the support via the centering disk, the magnetic loop assembly is provided with a gap, and the voice coil is inserted into the gap. The electric loudspeaker is characterized by further comprising a compensation suspension sheet which has elasticity and can vibrate up and down, wherein the compensation suspension sheet is fixed in the support and is fixed with the magnetic loop assembly. When the voice coli and the centering disk mechanically vibrate up and down, the magnetic loop assembly and the compensation suspension sheet also mechanically vibrate up and down. When vibrating up and down, the voice coil is kept in an effective magnetic field of the magnetic loop assembly, thereby compensating the problem of low efficiency and further reducing nonlinear distortion.
Description
Technical field
The utility model relates to the loud speaker field, especially about a kind of dynamic speaker.
Background technology
The response dynamics of existing dynamic speaker is relevant with the dynamics of the quality of vibrational system and drive system mostly, can not be by increase response dynamics under the constant situation of two system parameterss on it.Existing electrodynamic type (moving-coil type) loud speaker generally all is that vibrational system (comprising voice coil loudspeaker voice coil, centring disk, drum paper and dust cap) is done mechanical oscillation up and down, because loud speaker is for a long time in powerful operating state, during the voice coil loudspeaker voice coil up-down vibration, the as easy as rolling off a log effective magnetic field that exceeds of voice coil loudspeaker voice coil, thus make Whole Response efficient low and cause nonlinear distortion easily.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of dynamic speaker that can improve response efficiency and reduce nonlinear distortion is provided.
For achieving the above object, the utility model has adopted following technical scheme: a kind of dynamic speaker, the centring disk and the magnetic loop assembly that comprise support, voice coil loudspeaker voice coil, have elasticity and energy up-down vibration, described voice coil loudspeaker voice coil is suspended on the inside of described support by described centring disk, described magnetic loop assembly has the gap, described voice coil loudspeaker voice coil inserts in the described gap, it also comprises the compensation suspension sheet with elasticity and energy up-down vibration, and described compensation suspension sheet is fixed on the inside of described support and fixes with described magnetic loop assembly.
Further, described magnetic loop assembly comprises cup, magnetic conduction sheet and magnet, described magnetic conduction sheet and described magnet stack fixing up and down and form global facility, described global facility is positioned at the inside of described cup, described gap is formed between described cup and the global facility and around described global facility, described cup and described compensation are hung sheet and fixed.
Further, the inside of described support has first step and second step, and described first step is higher than second step, and described centring disk and described first step are fixed, and sheet is hung in described compensation and described second step is fixed.
Further, described cup and described compensation suspension sheet is adhesively fixed.
Further, described compensation is hung sheet around described cup.
Further, described dynamic speaker also comprises bulging paper and dust cap, and described bulging paper overlaps described voice coil loudspeaker voice coil admittedly and is fixed on the inside of described support, and described dust cap is fixedlyed connected with described bulging paper.
The beneficial effects of the utility model are: when voice coil loudspeaker voice coil and centring disk are done mechanical oscillation up and down, magnetic loop assembly and compensation are hung sheet also along with mechanical oscillation up and down, remain in the effective magnetic field of magnetic loop assembly when making the voice coil loudspeaker voice coil up-down vibration always, thereby remedied inefficient problem, and then reduced nonlinear distortion; Because the magnetic loop assembly is along with up-down vibration, and the general sole mass of magnetic loop assembly big (quality is big more, and the response dynamics is big more), the buffering dynamics is also bigger during up-down vibration, thereby has strengthened the significant response dynamics; Owing to remain in the effective magnetic field of magnetic loop assembly during the voice coil loudspeaker voice coil up-down vibration always, can under the situation of using littler more low performance magnet, effectively cut and utilize magnetic field, thereby make its conversion efficiency higher, reduced the magnet material cost.

Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
As shown in Figures 1 and 2, the present embodiment loud speaker comprises support 3, magnetic loop assembly, compensation suspension sheet 9, voice coil loudspeaker voice coil 5 and centring disk 4.
Compensation is hung sheet 9 and is fixed on the second step of support 3, and the magnetic loop assembly hangs on this compensation and hangs sheet 9.The magnetic loop assembly comprises U type cup 8, magnetic conduction sheet 6 and magnet 7, this magnetic conduction sheet 6 stacks the upper surface that is fixed on magnet 7 and forms a global facility, the lower surface of this magnet 7 and cup 8 are fixing, make this global facility be fixed on the inside of this cup 8, and form annular gap 12 between this global facility and the cup 8 around this global facility.Voice coil loudspeaker voice coil 5 is fixing with centring disk 4, and this centring disk 4 is fixed on the first step of support 3, and this voice coil loudspeaker voice coil 5 inserts in the gap 12 downward vertically.
Loud speaker also comprises bulging paper 2, and this support 3 also has the 3rd step, and the 3rd step is higher than first step.The edge of drum paper 2 is fixed on the 3rd step, and the center of drum paper 2 is solidly set on the voice coil loudspeaker voice coil 5.
Loud speaker also comprises dust cap 1 and terminal board 10.The welding lead 11 of voice coil loudspeaker voice coil 5 is electrically connected with terminal board 10, and dust cap 1 is fixing with drum paper 2.
This loud speaker can adopt following assemble sequence:
Magnetize after the magnetic loop assembly that assembles and compensation hung the bonding drying of sheet 9 usefulness glue, and the formation suspension.
The suspension that processes is fixed on the respective step of support, keeps having the space between cup 8 bottoms and support 3 bottom surfaces.
Centring disk 4 is placed into the respective step place of support 3; Then, voice coil loudspeaker voice coil 5 usefulness centralizers are entangled and vertically insert in the gap 12 of magnetic loop assembly, and utilize glue that voice coil loudspeaker voice coil 5 and centring disk 4 are adhesively fixed, centring disk 4 and support 3 are adhesively fixed; Then, first applying glue is in the step place that support is placed drum paper 2, and the edge of drum paper 2 is placed into the respective step place of support 3, and voice coil loudspeaker voice coil 5 is then entangled at the center of drum paper 2; At last, applying glue and will rouse paper 2 and be adhesively fixed with voice coil loudspeaker voice coil 5, thus finish the installation of vibration section.
After waiting the glue bone dry of the section of vibration, voice coil loudspeaker voice coil welding lead 11 and terminal board 10 are welded, at last that dust cap 1 is bonding with drum paper 2 usefulness glue, thus form the present embodiment dynamic speaker.
