If will make loudspeaker a performance better tone quality, then loudspeaker must be installed in the space of a box-shaped, but there is no design, the electric equipment products that generally are equiped with loudspeaker are improved the design of tonequality, so can't effectively improve the tonequality of small size loudspeaker for loudspeaker a.

Known again loudspeaker a, its overall structure there is no waterproofing design, so its waterproof and moisture resistance are relatively poor, and reduces its sound equipment quality.

In addition, the assembled component quantity of known loudspeaker a is many, and therefore comparatively trouble inconvenience in assembling reduces market competitiveness so increase manufacturing cost.

Summary of the invention

The purpose of this utility model is to provide a kind of structure that constitutes loudspeaker, a kind of structure that constitutes loudspeaker is installed on the framework of an arbitrary shape, and this framework is installed in a box body the place ahead, in order to do making frequency range perform to the best by airtight box body, and the effect of audio amplifier can be arranged, and can exempt the installing bullet and involve the basin frame, and can reach waterproof and dampproof effect.

The utility model is to provide a kind of structure that constitutes loudspeaker, install the oscillating plate that central authorities have dust cap in a framework the place ahead, and be equiped with a voice coil loudspeaker voice coil in oscillating plate below, be equiped with a packing ring in the voice coil loudspeaker voice coil below again, be equiped with an iron core and magnet in this packing ring below, it is characterized in that: this framework is a ring bodies, be provided with an inward flange in inner circumferential surface, and above-mentioned oscillating plate is clamped on the inward flange that is fixed on framework with a flanging ring, this framework is installed on the opening of a box body that cooperates its profile again, and this box body becomes a confined space.

The utility model is also to provide a kind of structure that constitutes loudspeaker, and the inward flange of this framework is provided with a perforation, and this oscillating plate is provided with relative hole, and pastes the tuning cloth of a waterproof in the hole outside of oscillating plate.

The utility model is also to provide a kind of structure that constitutes loudspeaker, and the inward flange of this frame circle is provided with a sound guide tube, and this sound guide tube stretches in the aforesaid box body.

The utility model can make frequency range perform to the best by airtight box body, and the effect of audio amplifier can be arranged, and can exempt the installing bullet and involve the basin frame, and can reach waterproof and dampproof effect.

Embodiment

For making the utility model clear and definite more full and accurate, cooperate following each diagram to describe in detail as the back now:

At first, see also Fig. 1,2, the utility model is to install the oscillating plate 2 that central authorities have dust cap 21 in a framework 1 the place ahead, and is equiped with a voice coil loudspeaker voice coil 3 in oscillating plate 2 belows, be equiped with a packing ring 4 in voice coil loudspeaker voice coil 3 belows again, be equiped with an iron core 5 and a magnet 6 in these packing ring 4 belows; Its feature is to be:

This framework 1 is the ring bodies for an arbitrary shape, be provided with an inward flange 11 in inner circumferential surface, and above-mentioned oscillating plate 2 is clamped on the inward flange 11 that is fixed on framework 1 with a flanging ring 7, this framework 1 device is on the opening 81 of the box body 8 of its profile of cooperation again, make this box body 8 become a confined space, as shown in Figure 3, in order to do making oscillating plate 2 be able to return by the air that is sealed in the box body 8, make frequency range perform to the best, and can reach waterproof and dampproof effect.

According to above-mentioned structure, because this oscillating plate 2 is to be sealed on fully on the opening 81 of box body 8, make this box body 8 become a confined space, and air can be enclosed in the box body 8, so outside or during to internal vibration when oscillating plate 2, can make oscillating plate 2 returns by the air that are sealed in the box body 8, thereby must exempt as known structure and must install the bullet ripple, thus simplified structure with the reduction manufacturing cost.

This oscillating plate 2 is directly to be installed on box body 8 front openings 81 again, must be installed on the basin frame and can exempt as known structure, so simplified structure to reduce manufacturing cost.

Moreover because this box body 8 is just like audio amplifier, thereby must make frequency range perform to the best, and this oscillating plate 2 is installed on box body 8 front openings 81, and becomes an airtight space, thereby must reach waterproof and dampproof effect, damages to keep away from moisture.

And this box body 8 is to be a confined space, and can utilize the space in the confined space to replace acoustical cotton, thus the reduction manufacturing cost, and can make frequency range perform to the best, and better acoustics can be arranged.

Designs simplification of the present utility model again, and must be convenient to assembling to reduce manufacturing cost, in order to do improving market competitiveness.

In addition, this box body 8 gets and is designed to various shape according to need, makes this box body 8 must have various different shapings to change, with the different demands in response to market.

See also Fig. 4, wherein the inward flange 11 of this framework 1 is provided with a perforation 11a, and this oscillating plate 2 is provided with relative hole 21a, and pastes the tuning cloth 22 of a waterproof in the hole 21a outside of oscillating plate 2; Must be by this tuning cloth 22 as the pressure adjustment of adjusting the air in box bodys 8, make the small size loudspeaker must show known toy trumpet the bass effect that can't show, this is another embodiment of the present utility model, and reference is provided.

See also Fig. 5, wherein the inward flange 11 of this framework 1 is provided with a sound guide tube 23, and this sound guide tube 23 stretches in the aforesaid box body 8, must be by this sound guide tube 23, make the small size loudspeaker must show bass effect, this is another embodiment of the present utility model, and reference is provided.

Comprehensive the above, the disclosed structure of the utility model is in the past not have, and can reach above-mentioned effect really, manages the important document that has possessed utility model patent, files an application utility model patent in accordance with the law.
