Abstract

The utility model discloses a large dynamic loudspeaker vibration plate which includes a vibration film and a corrugated ring which is connected with the periphery of the vibration film. The corrugated ring is composed of two rings which are connected with each other and are concentric. The cross section of the ring is semicircular, and the two rings are same in terms of semicircular orientation. The inner ring is connected with the periphery of the vibration film. Because the corrugated ring adopts the two rings which are connected with each other, the supporting force of the corrugated ring to the vibration film is shared by the rings, the semicircular radius of each ring is reduced, and the amplitude of each ring is also reduced.

Description

A kind of large dynamic speaker diaphragm

Technical field

The utility model relates to a kind of large dynamic speaker diaphragm.

Background technology

The oscillating plate of loud speaker normally is connected with vibrating diaphragm by a semicircular arc ring and forms in the prior art.When the loud speaker of this structure is done large dynamic duty, in order to reach the large amplitude requirement, just the semi arch radius of ring must be accomplished very large, to satisfy the amplitude requirement.But the ring of this structure is relatively poor to the supporting role of vibrating diaphragm, and during the large dynamic duty of loud speaker, the stationarity of vibrating diaphragm vibration is difficult to guarantee, causes the distortion of loudspeaker sound.In addition, during the large dynamic duty of loud speaker, the amplitude of its oscillating plate is very large, typical low frequency amplitude peak can reach more than ten millimeter, also cause easily thus the coil sections of voice coil loudspeaker voice coil to run out of air gap uniform magnetic field district and cause distortion, perhaps locating branch slice and ring exceed its linear elasticity scope and cause distortion, or each moving component fatigue failure etc.

The utility model content

The utility model aims to provide a kind of large dynamic speaker diaphragm.

According to an aspect of the present utility model, a kind of large dynamic speaker diaphragm is provided, comprise vibrating diaphragm and the ring that is connected in the vibrating diaphragm periphery, ring be shaped as at least two concentricity settings and interconnective ring, the cross section of ring is semicircular arc, the semi arch of each ring is towards unanimously, and the ring of innermost circle is connected in the periphery of vibrating diaphragm.

In some embodiments, vibrating diaphragm is plate shaped.

In some embodiments, vibrating diaphragm is taper.

In some embodiments, vibrating diaphragm is W shape.

In some embodiments, vibrating diaphragm is that material is the vibrating diaphragm of paper, aluminium, titanium, foam, fiber or plastic cement.

In some embodiments, ring is circle or two semicircle rectangle.

In some embodiments, ring is that material is the ring of rubber, PU, foam or cloth.

The beneficial effects of the utility model: oscillating plate is the structure that single semicircular arc ring is connected with vibrating diaphragm compared to existing technology, technique scheme has changed the shape of ring, adopt a plurality of rings to interconnect, make ring be disperseed to bear by each ring to the support force of vibrating diaphragm, not only can dwindle the semi arch radius of single ring, the amplitude of each ring is reduced, avoid loud speaker greatly dynamically the time, to make voice coil loudspeaker voice coil run out of field regions because amplitude is excessive and caused distortion, perhaps locating branch slice and ring exceed elastic range and cause distortion, or each moving component fatigue failure.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Fig. 3 is the second structure section schematic diagram of the utility model preferred implementation.

Fig. 4 is the third structure section schematic diagram of the utility model preferred implementation.

Embodiment

With reference to figure 1, a kind of large dynamic speaker diaphragm, comprise vibrating diaphragm 1 and the ring 2 that is connected in vibrating diaphragm 1 periphery, ring 2 be shaped as at least two concentricity settings and interconnective ring 201, be preferably two rings 201, ring 201 cross section is semicircular arc, and the semi arch of each ring 201 is towards unanimously, and the ring 201 of innermost circle is connected in the periphery of vibrating diaphragm 1.Wherein the shape of vibrating diaphragm 1 can be taper or plate shaped or W shape (respectively such as Fig. 2, Fig. 3 and shown in Figure 4), its material can be the various materials that can be used for making vibrating diaphragm such as paper, aluminium, titanium, foam, fiber or plastic cement, and the internal structure of vibrating diaphragm 1 also can be honeycomb.And ring 2 can be circle or two semicircle rectangle, and its material can be the material that rubber, PU, foam or cloth etc. can be used for making ring.Because ring 2 adopts a plurality of rings 201 to interconnect, make the support force of 2 pairs of vibrating diaphragms 1 of ring be disperseed to bear by each ring 201, not only can dwindle the semi arch radius of single ring 201, the amplitude of each ring 201 is reduced.

Certainly, above embodiment just is explanation rather than restriction the utility model, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described scheme of the utility model patent claim change or modify, is included in the utility model patent claim.
