Description

A kind of waveform hangs limit structure

Technical field

Background technology

Existing audio device, such as loud speaker, generally comprise speaker frame, the vibrating diaphragm supported by described speaker frame, the voice coil loudspeaker voice coil be coupled with described vibrating diaphragm, and a magnetic receipt unit with described voice coil loudspeaker voice coil electromagnetic induction, thus order about described diaphragm oscillations, thus producing sound.Especially, described vibrating diaphragm is arranged on an opening part of described speaker frame, wherein when electromagnetic ground induces described voice coil loudspeaker voice coil reciprocating motion, correspondingly drives described diaphragm oscillations.But the direction of vibration of described vibrating diaphragm is uncontrolled, thus the sound timbre that described vibrating diaphragm can not reproduce.In order to obtain good sound timbre, described vibrating diaphragm only reciprocally should move in one direction with uniform amplitude.Such as, when described vibrating diaphragm is flatly settled, described vibrating diaphragm should only reciprocally move on vertical (up and down) direction, and the displacement upwards of described vibrating diaphragm should be identical with the downward displacement of described vibrating diaphragm.

That is, existing vibrating diaphragm also cannot be accomplished only to move along its axial direction, but can produce skew when axially moving and rock, and causes the sound that produces impure.A kind of vibration unit of typical loud speaker as shown in Figure 1, it can as the vibrational system of loud speaker, to be connected to voice coil loudspeaker voice coil thus to respond the input of audio signal and produce sound, or it also can as passive vibration unit, and the change via air pressure is driven by other horn systems and vibrates the auxiliary audio of generation.As shown in FIG., in prior art, the vibration unit of typical loud speaker comprises middle vibrating mass 1, is positioned at the outstanding limit 2 around vibrating mass 1, and external frame 3.Wherein outstanding limit 2 is in arch, and coaxial with vibrating mass 1.But this traditional vibration unit, in a vibration period, outstanding limit 2 still can not be played by the restriction of the direction of vibration of vibrating mass 1 in its axial direction.Because vibrating mass 1 is when departing from axial direction motion, and outstanding limit 2 itself does not produce the skew that corresponding pulling force stops vibrating mass 1, but is just eased when the biasing force of vibrating mass 1 is passed to the junction of outstanding limit 2 and external frame 3.That is, outstanding limit 2 can not prevent the skew of vibrating mass 1 timely and effectively.

Existing a solution, as shown in Figures 2 and 3, be arrange multiple ribs 4 between outstanding limit 2 and external frame 3, these ribs 4 play the effect of location, offset axial direction motion to prevent vibrating mass 1.That is, when producing skew, biasing force can be delivered to these ribs 4, and is cancelled in time.But, as shown in Figure 3, on a section of this vibration unit, can find out, this ribs 4 is all linear contact lay with vibrating mass 1 and external frame 3, and like this when vibrating mass 1 axially moves, the power of pullling of its axial motion also can be passed to ribs 4 soon, and be passed to external frame 3 soon further, so in fact the axial motion of vibrating mass 1 is also subject to the impact of ribs 4.That is, although this ribs 4 plays certain effect preventing offseting, vibrating mass 1 displacement in axial direction is also made, namely the stroke of vibration unit also reduces, the stroke of whole vibration unit will be affected like this, make acoustical quality not good, particularly bass tonequality.

In addition, in order to obtain better acoustical quality, particularly bass effect, the stroke of vibration unit or vibrating diaphragm needs large as far as possible, and the solution in traditional audio device normally makes large-sized vibration unit or vibrating diaphragm size, thus make existing audio device small and exquisite not.Such as, and for many slimline products containing audio device, panel TV, cell phone, laptop computer, wishes that the described audio unit used is not only flat but also thin as much as possible, thus makes its slimline product can maintain unique design and profile.Bulky audio device is not suitable for designing in these slimline products.

Embodiment

Below describe and realize the present invention for disclosing the present invention to enable those skilled in the art.Preferred embodiment in below describing only as an example, it may occur to persons skilled in the art that other apparent modification.The general principle of the present invention defined in the following description can be applied to other embodiments, deformation program, improvement project, equivalent and not deviate from the other technologies scheme of the spirit and scope of the present invention.

It is the vibration unit 100 according to first preferred embodiment of the present invention as shown in Fig. 3 to Fig. 5 B, it comprises the vibrating elements 10 being positioned at centre, be positioned at the outstanding limit structure around described vibrating elements 10, described outstanding limit structure comprises an elastic suspended limit 20, and is positioned at the framework 30 around described elastic suspended limit 20.That is, described elastic suspended limit 20, it is made up of elastomeric material, and extends between described vibrating elements 10 and described framework 30, to limit the vibration of described vibrating elements.Described vibrating elements 10 can be circular, oval, square or other polygons, and in this preferred embodiment, described vibrating elements 10 is oval.Described elastic suspended limit 20 also correspondingly forms substantially elliptical around described vibrating elements 10.Described framework 30 can be various shape, and the present invention is unrestricted in this regard.

In this preferred embodiment, described vibration unit 100 also comprises multiple spacing rib 40, multiple described spacing rib 40 extends between described vibrating elements 10 and described framework 30, thus forms the structure of height fluctuating between described vibrating elements 10 and described framework 30.Described spacing rib 40, for position-limiting action, departs from the displacement of its central shaft to prevent described vibrating elements 10.More particularly, when described vibrating elements 10 will depart from its central shaft and produce skew, corresponding described spacing rib 40 will produce reverse pulling force, to offset the biasing force causing described vibrating elements 10 to produce skew.It is worth mentioning that, described spacing rib 40 can be extend along the direction that the outer surface with corresponding described vibrating elements 10 is vertical with the inner peripheral surface of corresponding described framework 30, as shown in Figure 3, also can be arrange along the radial direction of described vibration unit 10, or arrange obliquely.This arrangement mode can produce accordingly along the pulling force in these directions, thus effectively prevents described vibrating elements from producing skew along these directions.

It is worth mentioning that, these spacing ribs 40 can be arranged in described vibrating elements 10 around equably, and symmetrically can arrange relative to the center of described vibrating elements 10.As an example, as shown in Figure 3, these spacing ribs 40 comprise the spacing rib 401 in left side and the spacing rib 402 in right side.When described vibration unit about 100 is placed and when normally working, described vibrating elements 10 axially moves up and down, when described vibrating elements 10 is wanted to offset left, the spacing rib 402 in described right side reversal interlocking relay to the right can be subject to immediately, thus stop described vibrating elements 10 to offset further left.Otherwise, when described vibrating elements 10 is wanted to offset to the right, the spacing rib 401 in described left side reversal interlocking relay left can be subject to immediately, thus stop described vibrating elements 10 to offset further to the right.Like this, the direction of vibration of described vibrating elements 10 can be limited on above-below direction axially by described elastic suspended limit 20 and described spacing rib 40 effectively.

Described elastic suspended limit 20 can be the structure had shown in Fig. 1, itself and described vibrating elements 10 are arranged coaxially, and along in the radial direction of described vibrating elements 10, its cross section forms waveform or arch, as shown in Figure 5 B, the central shaft thus along described vibrating elements 10 can form annular rib.It is worth mentioning that, spacing rib 40 described in each is arranged from described elastic suspended limit 20 projection, with the circumferentially formation height relief fabric at described vibrating elements 10.That is, described " waveform " of the present invention can not be the wave-like that strict similar water is formed, but can be formed with pleated structure or similar watt of rib paper structure around described vibrating elements 10.

As shown in Figure 3, described elastic suspended limit 20 is divided into multiple outstanding limits section 201 in fact by multiple described spacing rib 40.The quantity of described spacing rib 40 is unrestricted, and it can adjust according to different needs.In example in figure 3, described elastic suspended limit 20 is separated into 8 described outstanding limit sections 201 by 8 described spacing ribs 40.Described in each, spacing rib 40 is also made up of elastomeric material, and it can be made up of same elastomeric material with described elastic suspended limit 20, also can be made up of different elastomeric materials.When described spacing rib 40 is made up of same material with described elastic suspended limit 20, multiple described spacing rib 40 can be one-body molded with described elastic suspended limit 20.That is, can in an injection step, use a mould to inject predetermined elastomeric material, thus make with the assembly of multiple described spacing rib 40 with described elastic suspended limit 20 simultaneously.It is worth mentioning that, in forming process, described predetermined elastomeric material also can be coated on described vibrating elements 10, thus forms an elastomeric overmold layer 12.That is, described vibrating elements 10 can comprise inner vibration weight 11 and outside elastomeric overmold layer 12.It is worth mentioning that, described elastic suspended limit 20 and described spacing rib 40 also can utilize conventional method bonding with described framework 30 and described vibrating elements 10 by glue.

It is worth mentioning that, as shown in Figure 5 B, the domes on described elastic suspended limit 20 can form an annular recess 202.Spacing rib 40 described in each can be arranged on to outwardly convex both sides, described elastic suspended limit 20, or is only arranged on the side on described elastic suspended limit 10.In this preferred embodiment, described in each, spacing rib 40 and described annular recess 202 are positioned at the both sides on described elastic suspended limit 20, that is, described in each, spacing rib 40 does not extend into described annular recess 202, and just extend in the side on described elastic suspended limit 10, as shown in Figure 5 B, it extends in the upside on described elastic suspended limit 10 protrudingly.And form groove 203 between adjacent two described spacing ribs 40, thus described elastic suspended limit 20 and described spacing rib 40 define the structure that height rises and falls around described vibrating elements 10.

As shown in Fig. 3 and Fig. 5 A, spacing rib 40 cross section described in each can triangular in shape, also can trapezoidal, rhombus etc., thus can play the effect of being firmly located by connecting, again can not the axial motion of vibrating elements 10 described in overslaugh.More specifically, in the example shown in Fig. 3 and Fig. 5 A, in the form of sheets, and cross section is triangular in shape for spacing rib 40 described in each.The spacing rib of described triangle 40 can be connected with described vibrating elements 10 by a leg-of-mutton base, a leg-of-mutton summit is connected with described framework 30, or can be connected with described framework 30 by a leg-of-mutton base, a leg-of-mutton summit is connected with described vibrating elements 10.

Preferably, spacing rib 40 comprise vibratory elements link 41 and framework link 42 described in each.Described vibrating elements link 41 is that line is connected with the outer surface 101 of described vibrating elements 10, that is to say that the leg-of-mutton base of described spacing rib 40 contacts with the outer surface 101 of described vibrating elements 10 and is connected.Described framework link 42 and the inner peripheral surface 301 of described framework 30 to be connected, and that is to say that the vertex of a triangle of described spacing rib 40 contacts with the inner peripheral surface 301 of described framework 30 and is connected.It is worth mentioning that, the triangle of the cross section formation of described spacing rib 40 can be the shape of arbitrary triangle, as right-angled triangle, isosceles triangle, and can form equilateral triangle.It is worth mentioning that, each limit of triangle here can be straight line, also can be curve, and in the example in fig. 5, the part that spacing rib 40 described in each is connected with described elastic suspended limit 20 can be in arc line shaped.

It is worth mentioning that, this design makes described spacing rib 40 be greater than the bonding strength with described framework 30 with the bonding strength of described vibrating elements 10.Thus while the described vibrating elements 10 of prevention produces skew, the thrust making the described vibrating elements of promotion 10 move vertically is unlikely to be delivered to described framework 30 soon, and makes the stroke of described vibrating elements 10 and axial displacement not be much affected.That is, what described framework 30 applied described spacing rib 40 is unlikely to be passed to described vibrating elements 10 fast by the pulling force that described vibrating elements 10 retracts its initial position, but makes described vibrating elements 10 reach maximum axial displacement as far as possible.In other words, when described spacing rib 40 can not be made just to have started axial displacement from the initial position of centre, shorten axial displacement with regard to being subject to being with the effect from the restoring force of described framework 30 at once.

That is, as shown in Figure 2A and 2B, ribs 4 and vibrating mass 1 and external frame 3 are all that line is connected, and in the form of a substantially rectangular, such ribs 4 two ends by the same with the syndeton of vibrating mass 1 and external frame 3, thus have identical bonding strength in cross section.Like this, the pulling force retracting vibrating mass 1 that external frame 3 and ribs 4 play can be applied on vibrating mass 1 in real time, and causes the axial displacement of vibrating mass 1 also to have an impact.That is, although ribs 4 can play the effect of the skew of certain minimizing vibrating mass 1, serious adverse influence is created to the stroke of vibrating mass 1 simultaneously.And the present invention makes spacing rib 40 one end described in each and described framework 30 be formed a little is connected, and the other end and described vibrating elements 10 form line is connected, can play and prevent rocking and offseting of described vibrating elements 10, the axial displacement of described vibrating elements 10 can not be affected again.

As the vibration unit 100A that Fig. 6 to Figure 11 B is according to second preferred embodiment of the present invention, its comprise vibratory elements 10A, the waveform be centered around around described vibrating elements 10A hangs limit structure, and described waveform is hanged limit structure and comprised elastic suspended limit 20A, and framework 30A.Described elastic suspended limit 20A extends between described vibrating elements 10A and described framework 30A.In this embodiment, described elastic suspended limit 20A circumferentially forms wavy shaped configuration around described vibrating elements 10A.

Particularly, described elastic suspended limit 20A comprises the multiple waveforms spacing section of 21A circumferentially arranged, thus multiple described waveform spacing section of 21A formation wavy shaped configuration around described vibrating elements 10A.And the outstanding limit 2 in Fig. 1 is just formed with arch or waveform configuration in the radial direction of vibrating mass 1, thus effectively can not play the skew effect preventing described vibrating elements 10A.
