Description

Loudspeaker vibrating reed with peripheral wave form

Technical Field

The present invention relates to a loudspeaker vibrating reed, and more particularly to a loudspeaker vibrating reed with a periodic waveform.

Background

The general loudspeaker comprises a bass unit, a middle-tone unit and a treble unit. These three units are responsible for different frequencies. Most loudspeakers operate on the same principle. As with a typical moving coil speaker, when current flows through the wires to the voice coil, an electromagnetic field is generated. This forces the moving coil to move within the gap due to the electromagnetic field being directed at right angles to the magnetic field of the permanent magnet on the horn. The mechanical force generated by the movement makes the paper disc attached with the voice coil generate vertical and up-and-down vibration, so that air is vibrated, audio is emitted and transmitted to human ears, the purpose of restoring sound for human listening is achieved, and the conversion of electric energy into sound energy is realized.

However, since the diaphragm (e.g., diaphragm or damper) of the speaker is connected to the voice coil, and the diaphragm mainly functions to suspend the voice coil, the structure is mostly concentric circles and the cross section is wavy. The diaphragm basically determines the sounding quality of the loudspeaker, and the diaphragm has close relation with frequency response characteristics, tone quality, directivity, sensitivity and the like; the damper functions include (a) keeping the voice coil at the right position in the magnetic gap, (b) ensuring that the vibration system reciprocates axially when the voice coil is stressed, (c) determining the resonance efficiency of the loudspeaker together with the voice coil and the vibrating diaphragm of the vibration system, and (d) preventing dust from entering the magnetic gap. Therefore, the speaker can support the voice coil by the vibrating plate, and the quality of the vibrating plate can directly affect the sound quality of the speaker.

The method for manufacturing the prior loudspeaker vibrating plate comprises the following steps: impregnation: soaking a base material in a resin solution to enable the cloth material to absorb the resin and solidify to have certain hardness; and (3) drying: moving the cloth material to a drying device for drying to remove the water in the cloth material; hot press molding: moving the cloth material to a hot-press forming device, and heating and pressurizing the horn elastic wave forming area on the cloth material by the hot-press forming device to enable the horn elastic wave forming area to shrink into a wave structure with a plurality of rings; a cutting step: the horn spring shape is cut from the cloth material by a cutting device to obtain the finished horn spring.

Fig. 1 is an external perspective view of a conventional horn diaphragm 1, and the horn diaphragm 1 produced by the above-described manufacturing method generally has a center hole 2 and a wavy portion 3 located between the center hole 2 and an outer peripheral edge of the horn diaphragm 1 as shown in fig. 1 (here, an elastic wave is taken as an example), and the wavy portion 3 forms a plurality of peaks and a plurality of valleys in a radial direction of the horn diaphragm. In the conventional horn vibrating reed 1, the whole body is immersed in the resin solution in the immersion step, and after the resin solution is dried and cured, the whole body of the horn vibrating reed 1 has substantially the same hardness. In the conventional loudspeaker vibration piece 1, the plurality of waves are formed in the radial direction of the loudspeaker vibration piece 1 to adjust the elasticity and hardness of the loudspeaker vibration piece 1 in the radial direction, so that the wave part 3 of the loudspeaker vibration piece 1 can provide the elasticity and the supporting force in the radial direction when the voice coil vibrates.

However, such a conventional loudspeaker vibration piece 1 provides elastic support for the voice coil only in one direction (radial direction), and lacks elasticity in the circumferential direction and the vertical direction, so that the loudspeaker vibration piece 1 is easily deformed over time, the service life thereof is reduced, and the output sound quality of the loudspeaker is affected.

Therefore, after observing the above-mentioned deletions, the present inventor believes that the loudspeaker vibrating reed structure of the existing loudspeaker still has the need of further improvement, and has produced the utility model.

a body 10, a through hole 11 is formed at the center of the body 10, so that the body 10 has an inner periphery 12 and an outer periphery 13. In this embodiment, the main body 10 is a cloth material formed by weaving a plurality of warp yarns and a plurality of weft yarns alternately. The warp and weft of the damper body 10 are selected from one or a combination of polyester fiber, cotton fiber, acryl fiber, silk fiber, polyethylene naphthalate (PEN), Aramid fiber (Aramid) and bamboo fiber. In the present embodiment, the body 10 is exemplified by a circular shape; however, the present invention is not limited thereto, and the body 10 may have a rectangular shape or a polygonal shape.

At least one annular wave portion 20, the annular wave portion 20 being formed between the inner periphery 12 of the body 10 and the outer periphery 13 of the body 10 around the through hole 11, the annular wave portion 20 having a plurality of wave crests 21 and a plurality of wave troughs 22 around the circumference of the body 10. As shown in fig. 2, the annular wavy portion 20 has two side surfaces 23 facing the inner circumferential edge 12 and the outer circumferential edge 13, respectively, and the wave crests 21 and the wave troughs 22 of the annular wavy portion 20 form wavy surfaces 24. The side surfaces 23 may be of the same or different heights.

At least one annular flat portion 30, the annular flat portion 30 having a flat surface in the circumferential direction of the body 10 and being formed between one or a combination of the annular wavy portion 20 and the outer periphery 13 of the body 10 and between the annular wavy portion 20 and the inner periphery 12 of the body 10. In the present embodiment, as shown in fig. 2, the annular wavy portion 20 forms the annular flat portion 30 with the outer periphery 13 of the body 10, and the annular wavy portion 20 also forms the annular flat portion 30 with the inner periphery 12 of the body 10. However, the present invention is not limited thereto, and the annular wavy portion 20 and the outer peripheral edge 13 of the body 10 and the annular wavy portion 20 and the inner peripheral edge 12 of the body 10 may not include any annular flat portion 30, so that the horn vibrating reed 100 is formed by only one or more annular wavy portions 20.

For further understanding of the structural features of the present invention, its technical means and intended advantages, reference will now be made to the use of the present invention in which it is believed that there is a further and specific understanding of the present invention as described below:

please refer to fig. 2, which is a perspective view of the first embodiment of the present invention. The utility model discloses a loudspeaker trembler 100 with wave form between week, by this annular wave portion 20 around having a plurality of crests 21 and a plurality of trough 22 on the circumferencial direction of this body 10 for this loudspeaker trembler 100 except can be by this annular wave portion 20 crest 21 and trough 22 (this wave surface 24) provide elasticity, support, the vibration adsorption power on this loudspeaker trembler 100 circumferencial direction and the vertical direction, can also provide elasticity and support on this loudspeaker trembler 100 radial direction by this both sides face 23 of this annular wave portion 20.

Therefore, the present invention provides a loudspeaker vibrating reed 100 with elasticity and support in multiple directions, which is not easily affected by the vibration system of the loudspeaker, such as the voice coil, and is fatigue-deformed, and can provide stable and long-lasting support for the voice coil in multiple directions.

Fig. 3 is an external perspective view of a second embodiment of the present invention. The second embodiment is different from the first embodiment in that the annular wavy portion 20 is plural, the annular wavy portions 20 are spaced apart from each other in a radial direction of the body 10, and one annular flat portion 30 is provided between two annular wavy portions 20. Fig. 3 illustrates two annular beads 20, and one annular flat portion 30 is disposed between the annular beads 20, such that the annular beads 20 are spaced apart from each other in the radial direction of the body 10. Therefore, the present invention can adjust the elasticity and the supporting force of the horn vibrating reed 100 at intervals.

In the present embodiment, the amplitude W of one of the annular wavy portions 20 (the amplitude W is the distance between two adjacent wave troughs 22) is different from the amplitude W of the other of the annular wavy portions 20 (the amplitude W of the annular wavy portion 20 close to the inner peripheral edge 12 is smaller than the amplitude W of the annular wavy portion 20 close to the outer peripheral edge 13), which is taken as an example, so that the present invention can provide different degrees of elasticity and supporting force at different radial distance positions. However, the present invention is not limited thereto, and the amplitudes W of the annular wavy portions 20 may be the same; therefore, the present invention can provide the same degree of elasticity and supporting force at different radial distances from the position of the horn vibrating reed 100.

It should be noted that when there are a plurality of annular wavy portions 20, the annular wavy portion 20 is also formed with a plurality of wave crests 21 and a plurality of wave troughs 22 in the radial direction of the body.

Fig. 4 is an external perspective view of a third embodiment of the present invention. The third embodiment has a plurality of the annular beads 20 as the second embodiment, but the third embodiment is different from the second embodiment in that the annular beads 20 are continuously disposed from each other in the radial direction of the body 10, that is, the annular beads 20 are disposed adjacent to each other. Therefore, the present invention can provide the elasticity and the supporting force of the horn vibrating reed 100 on a continuous region of the horn vibrating reed 100.

In the present embodiment, the amplitudes W of the annular wavy portions 20 (i.e., the distances between two adjacent wave troughs 22) are different from each other, as an example. The circumferential elasticity and supporting force provided by each of the annular undulations 20 varies according to the amplitude W thereof. For example, in one of the annular wavy portions 20, the smaller the distance between the wave troughs 22 (the smaller the amplitude W), the greater the density of the wave troughs 22, the greater the support strength provided in the circumferential direction; the greater the distance between the valleys 22 (the greater the amplitude W), the lower the density of the valleys 22, the less the support strength provided in the circumferential direction, and the higher the elasticity.

In the present embodiment, as shown in fig. 4, three annular waves 20 are included. Specifically, the amplitude W of the annular wave portion 20 closest to the inner circumferential edge 12 of the body 10 is the smallest, and the amplitude W of the annular wave portion 20 farthest from the inner circumferential edge 12 of the body 10 is the largest. Thus, the amplitude W of the annular wave portions 20 gradually increases from the inner peripheral edge 12 to the outer peripheral edge 13 of the body 10, so that the amplitude W of each of the annular wave portions 20 is larger than the amplitude W of the annular wave portion 20 located on the inner ring thereof and smaller than the amplitude W of the annular wave portion 20 located on the outer ring thereof. Thus, the present embodiment can provide different degrees of elasticity and support force at different radial distance positions of the horn vibrating reed 100, so that the inner periphery 12 near the horn vibrating reed 100 provides relatively high strength support force and relatively low strength elasticity, and the support force gradually decreases and the elasticity gradually increases toward the outer periphery 13, and the outer periphery 13 provides relatively low strength support force and relatively high strength elasticity. However, the present invention is not limited thereto, and the amplitudes W of the annular wavy portions 20 continuously provided may be the same as each other, and may be adjusted so that the amplitude W of the annular wavy portion 20 closest to the inner circumferential edge 12 of the main body 10 is the largest and the amplitude W of the annular wavy portion 20 farthest from the inner circumferential edge 12 of the main body 10 is the smallest.

In addition, in the present embodiment, in one annular wavy portion 20, the amplitude W (the distance between the wave troughs 22) of each wave crest 21 is the same. Thus, the present embodiment can provide the same degree of elasticity and supporting force at the same radial distance position of the horn diaphragm 100. However, the present invention is not limited thereto, and the amplitude W of the peak 21 in one of the ring-shaped wavy portions 20 may be different, so that when other elements, such as a metal wire, are further provided on the horn vibrating reed 100, the elasticity and the supporting force may be adjusted corresponding to the position of the metal wire.

In addition, it should be noted that, in the present embodiment, the annular flat portion 30 is not included between the annular wavy portion 20 and the inner peripheral edge 12 of the body 10.

Another preferred embodiment of the present invention having a plurality of annular wavy portions 20 is described below with reference to fig. 5A and 5B and fig. 6A, 6B and 6C.

Fig. 5A and 5B are partial perspective views of another preferred embodiment of the present invention, which is a partial perspective view of the inner peripheral edge 12 of the horn vibrating reed 100 having a circumferential waveform of the present invention looking toward the outer peripheral edge 13. Fig. 5A shows an embodiment in which the crests 21 of each of the annular undulations 20 are positioned in alignment with one another, while fig. 5B shows an embodiment in which the crests 21 of each of the annular undulations 20 are at least partially staggered with respect to one another. Fig. 5A and 5B illustrate an embodiment in which the height H of each peak 21 of one of the annular wavy portions 20 is the same as the height H of each peak 21 of the other of the annular wavy portions 20, but the amplitude W (the distance between the two troughs 22) of one of the annular wavy portions 20 is different from the amplitude W of the other of the annular wavy portions 20, but the present invention is not limited thereto.

In fig. 5A, the position of each wave front 21 of one of the annular wave portions 20 and the position of each wave front 21 of the other of the annular wave portions 20 are aligned with each other, so that the positions of the wave crests 21 of the annular wave portions 20 are aligned with each other in the radial direction of the body 10. In fig. 5B, the position of the wave front 21 of one of the annular waves 20 and the position of the wave front 21 of the other of the annular waves 20 are staggered with each other in the radial direction of the body 10.

Fig. 6A, 6B and 6C are partial sectional perspective views of other preferred embodiments of the present invention, which are partial perspective views of the sectional plane (as the section line a-a of fig. 4) of the annular wave portion 20 along the radius of the horn vibrating reed 100 having a circumferential waveform of the present invention, and respectively show different embodiments of the height H of the peak 21 of the annular wave portion 20.

In fig. 6A, the height H of the crest 21 of each of the annular beads 20 is the same. Therefore, the utility model discloses can provide the vibration adsorption area of the same degree, the shock absorption power promptly at the radius distance position department of difference.

In fig. 6B, the height H of the crest 21 of each of the annular beads 20 is smaller than the height H of the crest 21 of the annular bead 20 located on the inner ring thereof and larger than the height H of the crest 21 of the annular bead 20 located on the outer ring thereof. In other words, the height H of the peak 21 of the annular wavy portion 20 closest to the inner periphery 12 of the body 10 is the highest, and the height H of the peak 21 of the annular wavy portion 20 farthest from the inner periphery 12 of the body 10 is the lowest, so that the height H of the peak 21 of the annular wavy portion 20 gradually decreases from the inner periphery 12 to the outer periphery 13 of the body 10. Therefore, the utility model discloses can provide the ascending vibration absorbing power of the vertical direction of different degrees in different radius distance position department, make this loudspeaker trembler 100 have stronger vibration absorbing power at this internal peripheral edge 12 of this body 10 to reduce gradually to this outer peripheral edge 13, and be the weakest for vibration absorbing power at this outer peripheral edge 12 of this body 10.

In fig. 6C, the height H of the crest 21 of each of the annular beads 20 is greater than the height H of the crest 21 of the annular bead 20 located on the inner ring thereof and less than the height H of the crest 21 of the annular bead 20 located on the outer ring thereof. In other words, the height H of the peak 21 of the annular wave portion 20 closest to the outer periphery 13 of the body 10 is the highest, and the height H of the peak 21 of the annular wave portion 20 farthest from the outer periphery 13 of the body 10 is the lowest, so that the height H of the peak 21 of the annular wave portion 20 gradually increases from the inner periphery 12 to the outer periphery 13 of the body 10. Therefore, the utility model discloses can provide the ascending vibration absorbing power of the vertical direction of different degrees in different radius distance positions, make this loudspeaker trembler 100 have stronger vibration absorbing power in this outer peripheral edge 13 of this body 10 to reduce gradually to this internal periphery 12, and be the weakest for vibration absorbing power at this internal periphery 12 of this body 10.
