Embodiment
For making object of the present invention, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the present invention is described in more detail.
Please refer to Fig. 1, the loudspeaker that the embodiment of the present invention 1 provides comprise support 101, magnet fixed mount 102 and resonant ring 103.In this embodiment, the center of circle of support 101, magnet fixed mount 102 and resonant ring 103 is all on same straight line.
Fig. 2-Fig. 5 is the different structural representations of four kinds of the resonant ring 103 of the present embodiment, and concrete, Fig. 2 is arc-shaped responant diaphragm schematic diagram; Fig. 3 is horizontal resonant film 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 is all made up of steel material, and mainly play a part to support and fixing loudspeaker in the process that loudspeaker use, the bulging paper of loudspeaker and the outer edge of support 101 link together, and form a cone shape, for sounding.
The center of support 101 and the outer edge center of circle, on same straight line, can be combined with magnet fixed mount; Connecting portion between the center of support 101 and outer edge, can make different shapes according to different sound equipments, and in the process used, the wire of loudspeaker is often fixed on connecting portion.
Magnet fixed mount 102 is U iron, is the hollow columnar structures that one end is closed; And U iron and support 101 are fixed; The axis of U iron overlaps with the center line of described support, to be combined as a whole structure with support.As the necessary structure of magnetic horn in conventional, the U iron of the hollow columnar structures that one end is closed inner can interior magnet, voice coil loudspeaker voice coil, washer etc. for the device of sounding.
Above-described support 101, magnet fixed mount 101 constitute the basic building block of sound horn device, in the process of loudspeaker work, after energising, the voice coil loudspeaker voice coil and the bullet ripple that are arranged in U iron inside are receiving the effect of electric field force and then are producing vibration in magnetic field, so just make the air compressing between drum paper and U iron or extension, and then drive drum paper to vibrate together, this completes the process that electric energy is converted to acoustic energy.
Be fixed on the resonant ring 103 of support 101 outer edge, common fixed form is be bonded at 101 outer edges by glutinous for the inner ring of resonant ring 103, and wherein, support 101 outer edge overlaps with resonant ring 103 ring heart line, makes original loudspeaker profile obtain amplification intuitively.Resonant ring 103 is made up of responant diaphragm and fixed support flanging two parts.Generally, loudspeaker drum paper and face, dust cover place are called the front of loudspeaker, 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 contrary.
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 the plane of reference cross surface that formed crossing with between resonant ring 103 by resonant ring 103 ring heart line.
In the process of sound horn, electrical conductor is subject to the effect of power in magnetic field, thus vibration, and then make air in drum paper be compressed or uphold, and then make whole bulging paper and voice coil vibrations, produce inner ring vibration sound wave; Owing to having resonant ring 103 at the outer edge of support 101, the air driven resonant ring 103 being compressed and upholding in drum paper vibrates, and forms outer shroud vibration sound wave; Inner ring vibration sound wave and outer shroud vibrate between sound wave and can produce resonance, and then when not increasing driving voltage, can improve the pronunciation volume of loudspeaker or producing stereo sound effect.
Meanwhile, because resonant ring 103 is nonmetallic materials, which reduces sound in the loss of support 101 outer edge, thus electro-acoustic conversion efficiency is improved.
The fixed support flanging being positioned at the responant diaphragm outer of ring-type is fixed up with audio amplifier cavity and forms the bearing edge of loudspeaker, and fixed support flanging can adopt the material identical with the responant diaphragm of ring-type to make.
The production method of a kind of loudspeaker provided of the present embodiment comprises, and is fixed on support 101 by magnet fixed mount 102, and forms core component; Make the inside edge of described resonant ring 103 coordinate with the outer edge of described support 101 and fix, thus make interior magnetic horn.
Please refer to Fig. 6, the loudspeaker that the embodiment of the present invention 2 provides, comprise support 601, magnet fixed mount 602 and resonant ring 603.In this embodiment, the functional configuration of support 601 and resonant ring 603 and annexation identical with the support 101 described in above-described embodiment 1 and resonant ring 103, do not repeat, only magnet fixed mount 202 be described further and explained.
Magnet fixed mount 602 is T iron, and T iron is by the location-plate of the axes normal of a central shaft and extended planar and 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.
The production method of the loudspeaker that the embodiment of the present invention 2 provides comprises, and is fixed on support 601 by magnet fixed mount 602, and forms core component; Make the inside edge of described resonant ring 603 coordinate with the outer edge of described support 601 and fix, thus make outer magnetic horn.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
