Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to further detailed description.
Embodiment mono-:
As shown in Figure 1 to Figure 3, the diaphragm of loudspeaker comprises the ball top 1 and the ring section 2 that is positioned at marginal position of the rigidity that is positioned at center.The utility model vibrating diaphragm is plane structure, and plane vibrating diaphragm is conducive to reduce the thickness of loud speaker, is conducive to the slimming of product.Wherein, ball top 1 is planar structure, and is preferred, can adopt material or the foam material of honeycomb.The present embodiment ring section 2 is silastic material, and ring section 2 is by the mode moulding of injection moulding.The surround section 2 of this structure, be single layer structure, so just guaranteed the consistency of vibrating diaphragm, thereby make the diaphragm of loudspeaker have good stability, further guaranteed the stability of loud speaker sounding; The silicon rubber vibrating diaphragm has excellent heat resistance, and extensibility is large, and tensile strength is high and hardness is adjustable, thereby adopts silastic material, even single layer structure also has the acoustical behavior that the vibrating diaphragm desirable strength does not affect product.
Preferably, the material of ring section 2 adopts fluid silicone rubber, because fluid silicone rubber has good fluidity, sulfuration is fast, thereby is easy to injection mo(u)lding.
In addition, the core of ring section 2 has been removed part silicon rubber material, and namely ring section 2 is the circulus of hollow, and this structure can alleviate the weight of ring section 2, further alleviates the weight of vibrating diaphragm, thereby is conducive to improve the sensitivity of product.The inside edge of ring section 2 is provided with the 21Yu Qiu top, 21， joint portion, joint portion 1 of ball top 1 secure bond passes through the mode secure bond such as bonding.The outside of joint portion 21 is provided with the arc-shaped side section 20 that is connected with joint portion 21, and as shown in Figure 3, arc-shaped side section 20, when vibrating diaphragm vibrates, deformation can occur.
As a kind of improvement, the thickness of the utility model arc-shaped side section 20 is different from the thickness of joint portion 21, and the thickness of the present embodiment arc-shaped side section 20 is greater than the thickness of described joint portion 21.Because the thickness of arc-shaped side section 20 has direct impact to the parameters,acoustics such as F0 of vibrating diaphragm, and if the thickness of joint portion 21 increases the height of vibrating diaphragm than conference, further can increase the height of loud speaker; And for this ring section 2, adopting the structure of silastic materials, the F0 of vibrating diaphragm is often lower.Therefore, identical be unfavorable for improving the acoustical behavior of product if the thickness of arc-shaped side section 20 drops to thickness with joint portion 21, the parameters,acoustics such as the F0 of product are lower; If it is identical be unfavorable for the slimming of product that the thickness of joint portion 21 is raised to thickness with arc-shaped side section 20.Therefore, the large and less structure of the thickness of joint portion 21 of the thickness of the arc-shaped side section 20 of this ring of the utility model section 2, can adjust the parameters,acoustic of vibrating diaphragm, the acoustical behavior of improving product; And because the thickness of joint portion 21 is less, namely the thickness after ball top 1 and joint portion 21 combinations is also less, thereby has reduced the height of vibrating diaphragm, is conducive to further reduce the height of loud speaker.
Wherein, arc-shaped side section 20 comprises arc-shaped side body and the reinforced reinforcement part 201 that is arranged at arc-shaped side body surface that forms, as shown in Figure 3, reinforcement part 201 covers the central area at arc-shaped side body top, this structure has increased the thickness of reinforcement part 201 on the basis of arc-shaped side body, thereby adjusted the parameters,acoustic of product, improved the acoustical behavior of product.
Embodiment bis-:
As shown in Figure 4, the main distinction of the present embodiment and above-described embodiment is, reinforcement part 201 ' covers the zone of arc-shaped side body away from the arcwall face of ball top 1 one sides, this structure has increased the thickness of arc-shaped side section 20 ' equally, can adjust the parameters,acoustic of vibrating diaphragm, improve the acoustical behavior of product.And the thickness of joint portion 21 is less, is conducive to reduce the thickness of vibrating diaphragm on its direction of vibration, further can reduce the thickness of loud speaker.
In addition, reinforcement part 201 ' also can be arranged at the side of arc-shaped side body near ball top 1, has equally the technique effect of the present embodiment, equally in protection range of the present utility model.
Embodiment tri-:
As shown in Figure 5, the main distinction of the present embodiment and above embodiment is, reinforcement part 201 " cover the whole zone of arc-shaped side body upside, this structure has increased arc-shaped side section 20 equally " thickness, can adjust the parameters,acoustic of vibrating diaphragm, improve the acoustical behavior of product.And the thickness of joint portion 21 is less, is conducive to reduce the thickness of vibrating diaphragm on its direction of vibration, further can reduce the thickness of loud speaker.
It should be noted that, the position of reinforcement part arranges the structure that is not limited to above-mentioned three embodiment, also can have other to improve structure, can increase the part of arc-shaped side section or the thickness of Zone Full and get final product.And can to position and the overlay area of reinforcement part, adjust according to the actual conditions of product, parameters,acoustic is carried out to the adjustment of different amplitudes.Improve all in protection range of the present utility model accordingly.
Under above-mentioned instruction of the present utility model; those skilled in the art can carry out other improvement and distortion on the basis of above-described embodiment; and these improvement and distortion; all drop in protection range of the present utility model; those skilled in the art should be understood that; above-mentioned specific descriptions are just better explained the purpose of this utility model, and protection range of the present utility model is limited by claim and equivalent thereof.
