A kind of loudspeaker

Technical field

The utility model relates to sound equipment sounding field, relates in particular to a kind of loudspeaker.

Background technology

Loudspeaker are a kind of electro-acoustic elements that can convert the electrical signal to sound, are the vitals in the sound box system.At present, moving-coil type loudspeaker commonly used mainly comprise support, magnet and drum paper; Support forms the support profiles of the circle of loudspeaker; Magnet produces or keeps magneticaction, and relative with support fixing; Drum paper sticks on the support, is used for by the generation of vibration sound wave.In addition, loudspeaker can also comprise U iron, and U iron is used for covering on outside the magnet, and fixes with support, makes loudspeaker form interior magnetic horn; Loudspeaker also can comprise T iron, and T iron comprises that the central shaft of T iron inserts the centre bore of magnet, and central shaft and support are fixed, and make loudspeaker form outer magnetic horn.U iron or T iron are respectively applied to fixed magnet, so the two can be referred to as the magnet fixed mount.

Usually in the use of loudspeaker, some specific occasion may need to have larger phonation volume or produce stereo sound effect; Generally need to be adopted as loudspeaker this moment provides higher driving voltage, so that loudspeaker generation sound wave is stronger.The driving voltage increase causes the energy consumption of loudspeaker to increase.And then how in the situation that increases horn volume, reducing or keeping energy consumption constant is the technical barrier of current this area.

In addition, when increasing the sound horn volume, also need to increase the profile of support and iron cover, and then increase the weight of loudspeaker.The increase of weight can cause loudspeaker to carry and use very inconvenient.

In addition, owing to support is made by steel plate, so that the neighboring of support has larger coefficient of elasticity; And then when sound horn, the vibration of support need to consume more acoustic wave energy, causes the sound of these loudspeaker to decrease larger.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.

Please refer to Fig. 1, the loudspeaker that the utility model embodiment 1 provides comprise support 101, magnet fixed mount 102 and resonant ring 103, also comprise bulging paper of the prior art, and drum paper can stick on the support 101 by the prior art presentation mode.Among this embodiment, the center of circle of support 101, magnet fixed mount 102 and resonant ring 103 is all on the same straight line.

Fig. 2-Fig. 5 is four kinds of different structural representations of the resonant ring 103 of present embodiment, and is concrete, and Fig. 2 is circular-arc responant diaphragm schematic diagram; Fig. 3 is horizontal responant diaphragm schematic diagram; Fig. 4 is single broken line responant diaphragm schematic diagram; Fig. 5 is dual slope responant diaphragm schematic diagram.

Wherein, common support 101 all is comprised of steel material, mainly plays a part to support in the process that loudspeaker use and fixing loudspeaker, and the bulging paper of loudspeaker and the outer edge of support 101 link together, and form a cone shape, for sounding.

Can be combined with the magnet fixed mount on the same straight line in the center of support 101 and the outer edge center of circle; The center of support 101 and the connecting portion between the outer edge can be made different shapes according to different sound equipments, and in the process of using, the wire of loudspeaker often is fixed on connecting portion.

Magnet fixed mount 101 is U iron, is the hollow cylindrical structure of end sealing; And U iron and support 101 are fixing; The axis of U iron and the central lines of described support are with the support structure that is combined as a whole.As the necessary structure of magnetic horn in conventional, but the U iron inside interior magnet of the hollow cylindrical structure of end sealing, voice coil loudspeaker voice coil, washer are used for the device of sounding.

Above-described support 101, magnet fixed mount 101 have formed the basic building block of sound horn device, in the process of loudspeaker work, after the energising, the voice coil loudspeaker voice coil that is arranged in U iron inside has been subject to the effect of electric field force and then has produced vibration in magnetic field, so just so that air compressing or extension between drum paper and U iron, and then drive drum paper and vibrate together, so just finished the process that electric energy is converted to acoustic energy.

Be fixed on the resonant ring 103 of support 101 outer edges, common fixed form is bonded at 101 outer edges for the interior ring with resonant ring 103 sticks, and wherein, support 101 outer edges overlap with resonant ring 103 ring heart lines, intuitively so that original loudspeaker profile has obtained amplification.Resonant ring 103 is comprised of responant diaphragm and fixed support flanging two parts.Generally speaking, loudspeaker drum paper and dust cover place face are called the front of loudspeaker, and the front of loudspeaker is grooves of a cone shape, the opening direction of groove be called loudspeaker towards, the protrusion direction of the responant diaphragm of resonant ring 103 can be identical with the direction of loudspeaker, also can be opposite.

The cross section of resonant ring 103 is circular arc, linear, single fold-line-shaped, many fold-line-shapeds etc., and cross section herein refers to by intersecting the cross surface that forms between the plane of reference of resonant ring 103 ring heart lines and the resonant ring 103.

In the process of sound horn, electrical conductor is subject to the effect of power in magnetic field, thus vibration, and then so that drum paper Air be compressed or uphold, and then so that whole bulging paper and voice coil loudspeaker voice coil vibration, ring vibration sound wave in producing; Because the outer edge at support 101 has resonant ring 103, air driven resonant ring 103 vibrations that are compressed and uphold in the drum paper form outer shroud vibration sound wave; Can produce resonance between interior ring vibration sound wave and the outer shroud vibration sound wave, and then not increase in the situation of driving voltage, can improve the pronunciation volume of loudspeaker, perhaps produce stereo sound effect.

Simultaneously, because resonant ring 103 is nonmetallic materials, so just reduced sound in support 101 outer edge losses, thereby so that electro-acoustic conversion efficiency be improved.

The fixed support flanging that is positioned at the responant diaphragm outer of ring-type is fixed up with the audio amplifier cavity and forms the bearing edge of loudspeaker, and the fixed support flanging can adopt the material identical with the responant diaphragm of ring-type to make.

Please refer to Fig. 6, the loudspeaker that the utility model embodiment 2 provides comprise support 601, magnet fixed mount 602 and resonant ring 603.

Among this embodiment, the functional configuration of support 601 and resonant ring 603 and annexation are identical with above-described embodiment 1 described support 101 and resonant ring 103, do not do and give unnecessary details, and only magnet fixed mount 602 are described further and explain.

Magnet fixed mount 602 is T iron, and T iron is by a central shaft and the extended planar location-plate vertical with the axis of described central shaft; One end and the described location-plate of central shaft are fixed; In the assembling process of loudspeaker, T iron central shaft stretches in the centre bore of annular magnet, and then forms outer magnetic horn.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
