Abstract

The utility model relates to a high stable loudspeaker, which is mainly provided with yoke iron which is preliminarily provided with a plurality of ventilation holes to be combined on the bottom of a casing of the loudspeaker. A magnet is arranged in the yoke, an iron piece of a gasket is arranged on the magnet, a voice coil is arranged on the outer ring of the iron piece of the gasket, and a coil is wound on the voice coil. The utility model is characterized in that a combined part is arranged on the periphery of the yoke iron, the combined part is combined with a hanging edge, and the hanging edge is connected with the bottom of the voice coil; the voice coil is vertically arranged between the periphery of the yoke iron and the magnet, and the top of the voice coil is connected with another hanging edge. Thus, when the voice coil, wherein, both ends of which are limited vibrates, amplitude of bias placement is reduced, and a gap between the iron piece of the gasket and the yoke iron can be effectively reduced to be favorable for improving the sensitivity of the loudspeaker and reducing the distortion of the loudspeaker.

Description

The high stability loudspeaker

The utility model relates to a kind of loudspeaker, particularly a kind of high stability loudspeaker that reduce distortion.

As shown in Figure 1, general horn structure is by horn bulb (Frame) A, magnet (Magnet) B, voice coil loudspeaker voice coil (Voice Coil) C, play ripple (Damper) D, vibrating basin (Diaphram) E, dust cap (DustCover) F, yoke (Yoke) G, members such as liner (Washer) H and outstanding limit (Surround) I constitute, wherein yoke G newel outer rim is nested with a voice coil loudspeaker voice coil C, be wound with coil (Coil) C1 on the voice coil loudspeaker voice coil C, playing ripple D and vibrating basin E is placed on the voice coil loudspeaker voice coil C with the center nose end equally, the top of voice coil loudspeaker voice coil C sets firmly a dust cap F, voice coil loudspeaker voice coil C and vibrating basin E float between other mechanisms via playing ripple D and hanging limit I suspention, by this to form a complete horn structure.

By said structure as can be known, this voice coil loudspeaker voice coil C is connected with vibrating basin E, bullet ripple D and dust cap F for an end, in the mode of suspention around the outer rim of yoke newel, after energising, coil C1 on the voice coil loudspeaker voice coil C is attracted or is vibrated, make voice coil loudspeaker voice coil C begin to move up and down, and the vibrating basin E that is connected with voice coil loudspeaker voice coil C passes this vibration in air again, form the perceptible sound wave of ear.

Because the relation of material error, this voice coil loudspeaker voice coil C is attracted to begin to rock to the side when mobile, because the connected mode of voice coil loudspeaker voice coil C is the top suspension type, so the amplitude that voice coil loudspeaker voice coil C bottom swings is bigger, in case voice coil loudspeaker voice coil collides liner H or yoke G promptly can produce noise, in order to prevent that voice coil loudspeaker voice coil C from colliding both, so space J between yoke G newel and liner H internal diameter, then need to strengthen relatively, when increasing volume, this gap J needs bigger, yet space J is big more, the susceptibility of loudspeaker is also poor more, and therefore the space J that how to dwindle between yoke G and liner H internal diameter is topmost problem.

In view of this, the utility model is to improve at above-mentioned shortcoming further investigation, through behind the experimental reconstruction generation of the present utility model being arranged eventually in many ways.

Main purpose of the present utility model is that a kind of high stability loudspeaker will be provided, and can reach the high stability performance.

Secondary objective of the present utility model is that a kind of high stability loudspeaker will be provided, and can obtain to reduce the high stability performance of distortion.

The purpose of this utility model is achieved in that

A kind of high stability loudspeaker, mainly be provided with the yoke of default a plurality of air-vents, can be for the outer casing bottom that is incorporated into loudspeaker, these yoke central authorities are provided with a short protruded stigma, establish a magnet on the protruded stigma, the sheathed voice coil loudspeaker voice coil of the outer rim of this magnet, winding coil on this voice coil loudspeaker voice coil, the voice coil loudspeaker voice coil top is connected with vibrating basin and outstanding limit, and it is characterized in that: this yoke periphery is provided with a joint portion, this joint portion is in conjunction with another outstanding limit, and this outstanding limit is connected with the other end of voice coil loudspeaker voice coil.

The set joint portion of this yoke periphery is the prominent lip that extends for to the inside.

The prominent lip of this yoke joint portion, its lower edge are provided with a portion of class and are connected with outstanding limit.

By this, the limited voice coil loudspeaker voice coil in these two ends is when vibration, and the amplitude of bias placement is dwindled, and can effectively reduce the gap of liner iron plate and yoke, helps to improve loudspeaker sensitivity and reduces the loudspeaker distortion, reaches the purpose of the high stability performance of reduction distortion.

The utility model is simple in structure, wherein this yoke periphery is provided with a joint portion, this joint portion can be for hanging the limit in conjunction with one, be somebody's turn to do the bottom that hangs the limit and be connected in voice coil loudspeaker voice coil, this voice coil loudspeaker voice coil vertically is built between yoke periphery and the magnet, and the top of this voice coil loudspeaker voice coil is connected with another outstanding limit, and this structure helps to improve loudspeaker sensitivity and reduces the loudspeaker distortion, has the high stability performance of low distortion.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.

Description of drawings:

Fig. 1 is the cutaway view of known horn structure;

Fig. 2 is the stereo appearance figure of the utility model embodiment;

Fig. 3 is the structure cutaway view of the utility model embodiment;

Fig. 4 is the structure cutaway view of another embodiment of the utility model.

See also Fig. 2, it is the stereo appearance figure that is implemented on the small-power loudspeaker for high stability loudspeaker of the present utility model, it mainly is the yoke 10 that is provided with the default air-vent 11 in a bottom, the top of yoke 10 combines with the horn bulb 42 that is the double wedge shape, and the central authorities of horn bulb 42 are provided with vibrating basin 41, and the periphery of this vibrating basin 41 then is provided with outstanding limit 40 and is connected with horn bulb 42.

As shown in Figure 3, it is internal view for the utility model embodiment, the periphery of this yoke 10 is provided with a joint portion 13, this joint portion 13 is to be a suitable distance and the prominent lip that extend internally, root edge in prominent lip is provided with a portion of class 14, this portion of class 14 also combines with another outstanding limit 15, these yoke 10 central authorities are provided with a short protruded stigma 12, on short protruded stigma 12, install a magnet 20, liner iron plate 21 is established in these magnet 20 tops, reserve a little space 22 between the prominent lip of this liner 21 and joint portion 13, roll the voice coil loudspeaker voice coil 30 that forms with a thin slice again and insert in this space 22, voice coil loudspeaker voice coil 30 bottoms are connected with outstanding limit 15, the top is connected with the outstanding limit 40 on surface again, the coil 31 of winding just places between the little space 22 on this voice coil loudspeaker voice coil 30, and the top of voice coil loudspeaker voice coil 30 then combines with vibrating basin 41, thereby forms the yoke 10 that inner voice coil loudspeaker voice coil 30 two ends have fulcrum.
