Embodiment
With reference to the accompanying drawings the utility model is described more fully, exemplary embodiment of the present utility model is wherein described.Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with figure and embodiment, the technical solution of the utility model is carried out to many-sided description.
As Fig. 1, shown in 2, comprise with sound basin with the loud speaker of concavo-convex muscle: sound basin cone 2 and ring 3.Sound basin cone 2 is cone, and ring 3 is arranged on the edge of one end that sound basin cone 2 diameters are large, and many concavo-convex muscle 1 are set in sound basin cone 2.As shown in Figure 2, concavo-convex muscle 1 is relative and sound basin centrum 2 is given prominence to, but concavo-convex muscle 1 is hollow structure, and the cross section of concavo-convex muscle 1 can be rectangle, waveform etc.
In order to change the diaphagras of sound basin, the sound radiation pressure when mode that increases concavo-convex muscle 1 in sound basin cone 2 is carried out the vibration of balance sound basin, makes frequency response curve more level and smooth, can reduce the loudspeaker distortions producing due to sound basin diaphagras.
According to an embodiment of the present utility model, sound basin cone 2 is formed in one with many concavo-convex muscle 1, and for example, sound basin cone 2 can adopt special mould molding with many concavo-convex muscle 1 in the time producing.
According to an embodiment of the present utility model, many concavo-convex muscle 1 being circumferentially uniformly distributed along sound basin cone 2.The quantity of many concavo-convex muscle 1 can design according to concrete demand, for example, be 10 etc.Can realize the object that reduces diaphagras by changing the quantity of concavo-convex muscle 1 and position, concrete quantity, weight, position need to be tested and simulation software simulation analysis is determined by actual assembled.
One end that ring 3 and the diameter of sound basin cone 2 are large is bonding by binding agent, or by other the connected mode such as buckle connection.The material of ring 3 is rubber etc.Also can be between adjacent concavo-convex muscle 1, and in sound basin cone 2, groove is set, groove along sound basin cone 2 circumferentially for being uniformly distributed.
