Background

The loudspeaker is actually a conversion equipment for converting electric energy into sound, when different electronic energy is transmitted to the coil, the coil generates magnetic field interaction of energy and the magnet, the interaction causes paper disc vibration, because the electronic energy changes at any time, the coil of the loudspeaker can move forwards or backwards, so that the paper disc of the loudspeaker can move along with the paper disc, and the action causes the density degree of air to change to generate sound.

Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 2 and 3, the present invention provides a preferred embodiment of a speaker.

A loudspeaker comprises a sound film 210, a hanging edge 220 and a supporting part 230, wherein the hanging edge 220 and the supporting part 230 are both in annular structures, the inner contour of the hanging edge 220 is connected with the outer contour of the sound film 210, the outer contour of the hanging edge 220 is connected with the inner contour of the supporting part 230, and the width of the hanging edge 220 is arranged in a non-equidistant mode.

Specifically, the speaker generally comprises four parts, including a high pitch area 211 and a middle low pitch area 212, which form the sound membrane 210, and a suspension edge 220 and a support 230, wherein the high pitch area 211 is arranged in the middle, the middle low pitch area 212 surrounds the high pitch area 211, both of which can be arranged integrally or separately, the suspension edge 220 is connected with the sound membrane 210 and the support 230, respectively, and mainly functions in vibrating, and the suspension edge 220 has different types, including but not limited to a paper suspension edge 220, a foam suspension edge 220, a rubber suspension edge 220, and a PU suspension edge 220, and different suspension edges 220 have different bass effects and different costs, particularly, the PU suspension edge 220, Polyurethane (PU), which is entirely named polyurethane, and is a high molecular compound, and the soft polyurethane is mainly a thermoplastic linear structure, which has better stability than PVC foam material, Chemical resistance, rebound resilience and mechanical property, and has smaller compression deformability.

Due to the problems of materials, shapes, sizes and even processing technology in the actual manufacturing process, the loudspeaker generates resonance phenomena, especially at least one frequency point which is not regularly speaking.

Therefore, the width of the hanging edge 220 is set in a non-equidistant manner, so that the wave crests and wave troughs generated by the split resonance can be effectively restrained, the vibration transmitted from the sound film 210 to the hanging edge 220 is scattered, and the resonance phenomenon caused by the vibration reflected from the hanging edge 220 is avoided. The sound film 210 can play a flatter and smoother frequency response characteristic, reduce high-frequency sound quality reduction caused by the split resonance, and provide high-quality playing sound. Referring to fig. 4, fig. 4 shows the optimization effect of the frequency spectrum achieved by different sound film structures, and the testing method is that a microphone is tested 10cm away from the sound film in the own space with few enough reflectors. A is the actually measured frequency response characteristic of the traditional sound film with a circular outer contour; b is the actually measured frequency response characteristic that the outline of the sound film is oval; and C is the actually measured frequency response characteristic that the outer contour of the sound film is in a triangle-like shape.

As shown by the frequency response characteristic of fig. 4, the conventional sound film has large troughs near 4100Hz, and has the characteristic of peak-to-valley fluctuation between 4700 and 6000 Hz; with the loudspeaker arrangement of the present invention, it is determined that the peaks and valleys due to the split resonance can be effectively suppressed.

In one embodiment, the hanging edge 220 is one of an axisymmetric structure, a centrosymmetric structure, and a rotationally symmetric structure. The axial symmetry structure is folded along a straight line, and the parts at two sides of the straight line can be superposed with each other; the pattern is in a central symmetry structure, rotates 180 degrees around a certain point and can be superposed with another pattern; the rotation symmetrical structure has the property of a symmetrical center, and can be superposed with the original graph after rotating around the symmetrical center for a certain angle. With the above symmetrical structure, on one hand, the assembly of the sound membrane 210, the hanging edge 220 and the supporting part 230 is facilitated, and on the other hand, the stability is strong.

Of course, the suspension edge 220 may have an asymmetric structure, which provides a stronger suppression of resonance.

In one embodiment, the shape of the hanging edge 220 is also related to the outline of the outer contour of the sound film 210 and the inner contour of the supporting portion 230, so that the shape of the hanging edge 220 has two preferable solutions. In a first aspect, the inner contour of the hanging edge 220 is circular, and the outer contour of the hanging edge 220 is non-circular; alternatively, the inner contour of the hanging edge 220 is non-circular, and the outer contour of the hanging edge 220 is circular; alternatively, the inner contour of the hanging edge 220 is non-circular, and the outer contour of the hanging edge 220 is non-circular. In a second aspect, the inner contour of the hanging edge 220 is an ellipse, and the outer contour of the hanging edge 220 is a non-ellipse; alternatively, the inner contour of the hanging edge 220 is non-elliptical, and the outer contour of the hanging edge 220 is elliptical; alternatively, the inner contour of the hanging edge 220 is non-elliptical, and the outer contour of the hanging edge 220 is non-elliptical.

The essence of the first and second solutions is the same, except that the shape of the inner or outer contour of the hanging edge 220 is changed, respectively, to achieve a non-equidistant arrangement of the width of the hanging edge 220. Only one is based on a circle and the other is based on an ellipse. The circular shape is the basic structure of the conventional speaker sound film 210, and the ellipse is a novel structure designed to solve the resonance generated by the circular sound film 210, but the elliptical annular overhang 220 may also generate resonance due to the problems of material, shape, size, and even processing technology.

In one embodiment, an outer contour of the hanging edge 220 is circular, and an inner contour of the hanging edge 220 is one of a polygon, a polygon-like shape, and an ellipse. Furthest realizes the width of dangling edge 220 is the setting of non-equidistance, and can have more regular shape, the implementation of the follow-up technology of being convenient for, like gluing, counterpoint etc..

The inner contour of the hanging edge 220 is an axisymmetric structure, which facilitates the implementation of the subsequent process and has a beautiful appearance.

Wherein, the corner of the similar polygon is an arc angle; or, the adjacent line section of the polygon close to the corner is an arc line section, so that the corner forms a zooming smooth shape, the width of the suspended edge 220 is changed moderately on the premise of reducing resonance, and other problems caused by the rapid change of the width of the suspended edge 220, such as sound extinction and abnormal sound, are prevented.

Wherein the polygon or polygon-like shape is one of a triangle, a square, a pentagon and a hexagon. The shape is preferably triangular, namely, the shape is regular, so that the implementation of the subsequent process is facilitated, the width of the hanging edge 220 is non-equidistant, the frequent occurrence of the same width is reduced, and the balance between the width and the width is better achieved.
