Abstract

A dustproof cover forms a third skirt edge at the outer edge, and the third skirt edge is outwards extended with an extension part which makes a dangling edge and the dustproof cover bonded into integral configuration by the overlap joint of a second skirt edge and the third skirt edge. The third skirt edge extended from the third skirt edge is fixed with a larger voice coil. Consequently, the utility model can be provided with a magnetic iron with larger body to increase the sound efficiency of a loudspeaker or reinforce the bass efficiency.

Description

The structural improvement of loud speaker

Technical field

The utility model relates to the structural improvement of loud speaker, and purpose is providing one can increase the loud speaker phonation efficiency or can strengthen the loadspeaker structure of bass effect.

Background technology

Press, as shown in Figure 1, be for generally commonly using the STRUCTURE DECOMPOSITION figure of loud speaker, wherein, loud speaker is to be equipped with voice coil loudspeaker voice coil 2 by one, the supporting seat 1 of magnet 3 and washer 6 is a main body, the body of supporting seat 1 is the round slot bore 11 that is formed with for ccontaining voice coil loudspeaker voice coil 2 and magnet 3, and above the round slot bore 11 of supporting seat 1 a sticking outstanding limit 4 and the dust cap 5 that be provided with, and the effect on its outstanding limit 4 is to constitute scooping out of 1 of dust cap 5 and supporting seat, after voice coil loudspeaker voice coil 2 energising, voice coil loudspeaker voice coil 2 will produce Magnetic Induction, and allows the voice coil loudspeaker voice coil 2 be the axle center reciprocating motion with the center of magnet 3, also just vibrate back and forth and produce the sound wave of different frequency, and reach the sounding effect of loud speaker along with voice coil loudspeaker voice coil 2.

And, the outer rim and the inner edge on general outstanding limit 4 are formed with first shirt rim 41 and second shirt rim 42 respectively, its outstanding limit 4 promptly overlaps combination by first shirt rim 41 with class's section 111 of round slot bore periphery mutually, and by second shirt rim 42 of inner edge joint for a dust cap 5, voice coil loudspeaker voice coil 2 then is fixed in dust cap 5 belows, and near dust cap 5 and outstanding limit 4 lap-joints.

Yet, 3C electric device now, towards designing toward light-weighted direction, the size that relatively is installed in the loud speaker of this 3C electric device also diminishes gradually, but still need possess suitable power output is arranged gradually, can reach due sound expression effect, the power output of loud speaker is then decided on the magnet size, but in the limited size dimension of loud speaker, how to assemble bigger magnet, and don't hinder the setting of hanging the limit, be still the problem that the utmost point is desired to overcome.

The utility model content

The structural improvement of the utility model loud speaker promptly is formed with one the 3rd shirt rim by dust cap in its outer rim, and the 3rd shirt rim also is outward extended with a forniciform extension, the configuration that outstanding limit and dust cap are bonded into one by second shirt rim and the 3rd shirt rim overlap joint, and can fix big voice coil loudspeaker voice coil by the extension that extend the 3rd shirt rim, and then can assemble the bigger magnet of body, to increase the pronunciation efficient of loud speaker.

Moreover this dust cap can inwardly dwindle, and then the bigger outstanding limit of assembling R, and there have outstanding limit to be subject to the R angle with the improvement habit to be less, and its material only can be selected the shortcoming of flexible material for use.

Embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

Its primary structure of the structural improvement of the utility model loud speaker as shown in Figure 2, be to be main body equally by a supporting seat 1, be formed with round slot bore 11 on the body of supporting seat 1 for ccontaining voice coil loudspeaker voice coil 2 and magnet 3, between the body of round slot bore 11 periphery shell blocks, be formed with class's section 111, other has 3 sticking round slot bore 11 tops of being located at, the outstanding limit of an annular, the outer rim on its outstanding limit 4 and inner edge are formed with first shirt rim 41 and second shirt rim 42 respectively, its outstanding limit 4 promptly overlaps combination by first shirt rim 41 with class's section 111 of round slot bore periphery mutually, and is supplied the joint of dust cap 5 by second shirt rim 42 of inner edge.

Focusing on of this case: this dust cap 5 is formed with one the 3rd shirt rim 51 in its outer rim, and the 3rd shirt rim 51 also is outward extended with an extension 52, the form of its extension 52 can be shown in the embodiment of this figure, it is form for an arcuation or other waves, texture, the configuration that outstanding limit 4 and dust cap 5 are bonded into one by second shirt rim 42 and the 3rd shirt rim 51 overlap joints, and mat the 3rd shirt rim 51 outward extending extensions 52 can be fixed a bigger voice coil loudspeaker voice coil 2, and then can assemble body bigger voice coil loudspeaker voice coil 2 and magnet 3, increase power output, and increase the phonation efficiency of loud speaker.

Moreover, as shown in Figure 3, shell and then assembling bigger outstanding limit 4, R angle, there have outstanding limit to be subject to the R angle with the improvement habit to be less, and its material only can be selected the shortcoming of flexible material for use, thereby can select the preferable material of rigidity for use, as fiber, its selectivity is more to be difficult for limitedly, and the R angle on outstanding limit 4 is bigger, the low-frequency resonance of this loud speaker is reduced, and the bass effect of sounding is preferable.

As mentioned above, the utility model provides a loadspeaker structure that can increase the loud speaker phonation efficiency, so, offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be one of the utility model preferred embodiment, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc. such as, identical, all should belong within creation purpose of the present utility model and the claim.
