Detailed description of the invention
With specific embodiment, the present invention is done further detailed description below in conjunction with the accompanying drawings.
Embodiment one:
As shown in Figure 1 and Figure 4, the diaphragm of loudspeaker includes vibrating diaphragm body and the composite bed 3 of the rigidity being incorporated into vibrating diaphragm body center；Wherein, vibrating diaphragm body is the macromolecular material of single or multiple lift, for the structure of relative flexibility, including being positioned at the central part 2 of center and being positioned at the ring portion 3 of marginal position.Central part 2 is used for composite bed 3 by mode secure bond such as bondings, and for planar structure, this structure is easy contraction distortion after vibrating diaphragm body has been suppressed and cooled down.
As shown in Figure 1 to Figure 3, there is, with central part 2, the reinforcement groove 21 that certain altitude is poor in what the present embodiment was provided with raised or sunken setting on plane central part 2, and wherein at reinforcement groove 21, the thickness of the thickness of vibrating diaphragm body and central part 2 planar section is consistent.After plane central part 2 arranges reinforcement groove 21, the tension force that central part 2 shrinks can be offset, be possible to prevent central part to deform.Reinforcement groove shown in Fig. 1 21 is three list structures be arrangeding in parallel, and vibrating diaphragm body is rectangular configuration, and the reinforcement part 21 of three list structures is parallel to the major axis limit of vibrating diaphragm body and arranges.Reinforcement groove 21 can be to protrude or the structure of depression, and the bending direction of reinforcement groove 21 can be identical, as shown in Figure 2 with the direction of ring portion 1 bending；Or the direction of reinforcement groove 21 bending is in opposite direction, as shown in Figure 3 with what ring portion 1 bent；These two kinds of structures all can offset the tension force that vibrating diaphragm shrinks, and prevents vibrating diaphragm body from deforming.
Due to the thickness of vibrating diaphragm body and the consistency of thickness of central part 2 planar section at reinforcement groove 21, therefore, after the vibrating diaphragm body of this band reinforcement groove 21 is combined by modes such as bondings with rigid composite layer 3, the whole central part of vibrating diaphragm body is planar structure, i.e. in the same plane with the planar section of central part 2, as shown in Figure 4.
Arrange on this central part 2 plane at vibrating diaphragm body of the present invention and there is, with central part 2, the reinforcement groove 21 that certain altitude is poor, reinforcement groove 21 can offset the tension force that central part 2 shrinks, prevent vibrating diaphragm contraction distortion, in addition, owing to the thickness of reinforcement groove 21 is identical with the thickness of the planar section of central part 2, therefore after composite bed 3 is combined with vibrating diaphragm body, whole central part 2 is at grade, the flatness of vibrating diaphragm increases, therefore, the vibrating diaphragm of this structure can reduce the distortion of product, improves the acoustical behavior of product.
Fig. 5 to Fig. 9 is the structural representation of some improvement projects of reinforcement groove 21 of the present invention.Reinforcement groove shown in Fig. 5 21 is five independent list structures, arranges along the direction being parallel to the rectangle short axle of vibrating diaphragm body.Reinforcement groove shown in Fig. 6 21 is three independent list structures, arranges along with rectangle vibrating diaphragm body major axis direction at an angle.Reinforcement groove 21 shown in Fig. 7 is rectangular ring structure, and reinforcement groove shown in Fig. 8 21 is circular annular form structure, may be contained within plane central part 2.Reinforcement groove 21 shown in Fig. 9 is three S type structures, and the direction along the rectangle short axle of vibrating diaphragm body extends.
These are only several embodiments of reinforcement groove 21 of the present invention, the structure of reinforcement groove 21 is not limited to above-mentioned shape, it is also possible to for other shapes such as V-type, racetrack etc., these improve all in protection scope of the present invention.Additionally, the shape of vibrating diaphragm body and central part 2 is also not necessarily limited to rectangle, can be other shapes such as circle or racetrack, the most within the scope of the present invention.
Embodiment two:
As shown in Figure 10, the present embodiment vibrating diaphragm body is the loop configuration of hollow, and edge is ring portion 1, and the inner side in ring portion 1 is provided with plane central part 2 ', and the mid portion 20 ' of central part 2 ' is the structure hollowed out.Central part 2 ' is circulus, for the composite bed with rigidity by mode secure bond such as bondings.The defects such as the central part 2 ' of this structure is easily deformed after equally existing compacting cooling, therefore, the present embodiment also is provided with reinforcement groove 21 ' on the central part 2 ' of this annular, and the present embodiment reinforcement groove 21 ' is the list structure of the straight line setting along rectangle vibrating diaphragm body.An ibid embodiment; reinforcement groove 21 ' can be raised or sunken structure; the thickness of reinforcement groove 21 ' place vibrating diaphragm body and the consistency of thickness of the planar section of central part 2, the shape of reinforcement groove 21 ' can also have some changes, is correspondingly improved the most within the scope of the present invention.
Similarly, the present embodiment arranges on the plane central part of this annular and there is, with central part, the reinforcement groove that certain altitude is poor, the tension force that central part shrinks can be offset, prevent vibrating diaphragm contraction distortion, in addition, due to the thickness of vibrating diaphragm body and the consistency of thickness of central part planar section at reinforcement groove, after composite bed is combined with vibrating diaphragm body, whole central part is at grade, the flatness of vibrating diaphragm increases, therefore, the vibrating diaphragm of this structure can reduce the distortion of product, improves the acoustical behavior of product.
Under the above-mentioned teaching of the present invention; those skilled in the art can carry out other improvement and deformation on the basis of above-described embodiment; and these improve and deformation; all it is within the scope of the present invention; those skilled in the art should be understood that; above-mentioned specific descriptions simply preferably explain the purpose of the present invention, and protection scope of the present invention is limited by claim and equivalent thereof.
