Abstract
The utility model discloses a damper with a sponge layer. The damper is horizontally arranged in a frame of a loudspeaker, and is composed of a disc corresponding to a central voice coil. The section of the damper is provided with a wavy structure. The damper includes a fabric layer. The damper is characterized in that the fabric layer of the damper is mainly composed of an upper fabric layer, a lower fabric layer and a middle sponge layer. The sponge layer is connected with an adhesive layer, or provided with a conducting wire strip or a conductive film which is arranged in an embedded manner. The damper of the utility model has the advantages of novel structure, good practical effect, and the like.
Description
Technical field
The utility model relates to loudspeaker accessory field, more particularly relates to a kind of simple and practical, effective bullet ripple with spongy layer that has.
Background technology
Existing loudspeaker play-wave is generally the wavy shaped configuration that adopts circular lamellar body, and it is section undulate radially, is arranged on voice coil loudspeaker voice coil, plays a part to connect and support voice coil loudspeaker voice coil, and the tonequality of loud speaker is had to material impact; The cloth (staple fibre or blending) that existing bullet ripple is made into by cotton or staple fibre is made, for intensity being provided and keeping elasticity, need to be on disk impregnation phenolic resins.If application number is CN03225547.0, the applying date is on 04 28th, 2003, patent name is a kind of bullet wave structure of improvement, include: play ripple body (1) and plain conductor (2), play ripple body (1) and be mainly a fiber weaving cloth shape body, and be suppressed into a section and be wavy annulus sheet, it is characterized in that: plain conductor (2) is radially arranged in along the crest or the trough that play ripple body (1) the some places that play ripple body (1).This patent adopts fiber weaving cloth material, just exists Oscillation Amplitude excessive, limited due to self hardness, may produce and wave, and produces different sound; There are other material-structures of employing for this reason, to alleviate Oscillating Coefficients, be CN200710066676.0 just like application number, the applying date is on 01 11st, 2007, patent name is that the bullet of loud speaker involves its manufacture method, it is characterized in that: formed by thermoplastic plastic injecting.Thermoplastics is directly by injection molding machine single injection-molded, and, displacement is stable for the bullet Bob that the dry goods being made into traditional employing fiber is made, but Oscillating Coefficients is again not as tradition plays ripple, affects the tonequality of loud speaker, soft not simple and honest.
Utility model content
The purpose of this utility model is exactly in order to solve the deficiency of prior art, and the one providing is simple in structure, alleviation Oscillating Coefficients, the band spongy layer bullet ripple that acoustical quality is good.
The utility model is to adopt following technical solution to realize above-mentioned purpose:
This bullet ripple with spongy layer, be horizontally set in the basin frame of loud speaker, the disk that You Yu center voice coil loudspeaker voice coil is corresponding forms, and section is provided with wave structure, include tissue layer, it is characterized in that: the tissue layer of this bullet ripple is mainly made up of upper and lower two fabric layers and middle spongy layer.
Described spongy layer is connected with adhesive-layer, or embedding is provided with wire bar or conducting film.
Described spongy layer can be to be disposed in whole or in part between upper and lower tissue layer.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
This bullet ripple with spongy layer is improved on existing fabric texture bullet ripple basis, adopts and in tissue layer, is embedded sponge, does not have and waves like this in the time of vibration, alleviate Oscillating Coefficients, keep tonequality stable, more balance is soft to make the sound of loud speaker, can not produce abnormal sound.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial cross section structural representation of the present utility model;
Fig. 3 is partial cross section of the present utility model structural representation.
Description of reference numerals: 1 plays ripple, 2 tissue layer, 3 spongy layers.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the bullet ripple 1 of the utility model band spongy layer, be horizontally set in the basin frame of loud speaker, the sheet disk that You Yu center voice coil loudspeaker voice coil is corresponding forms, section is provided with wave structure, include tissue layer, the tissue layer of this bullet ripple is made up of bilevel fiber fabric layer 2 and the spongy layer 3 in the middle of the two.Described spongy layer connects 3 and is connected to adhesive-layer, fixed with fiber fabric layer, can also connect wire bar or conducting film, embeds to be arranged on to play on ripple.
Experiment showed, in the above-described embodiments, the traditional bullet ripple of bullet Bob that contains spongy layer, effect of vibration is more balanced, plays ripple and is also difficult for deformed damaged, can excessively not wave, and the tonequality showing is more plentiful soft.
Described spongy layer can be whole being arranged between fabric as embodiment, or can also be part compartment of terrain, be arranged between tissue layer regularly.
In above-described embodiment, the thickness of spongy layer, size and position can arrange according to actual adjustment; Therefore the equivalent variations of doing according to the utility model claim, not departing under the prerequisite of the utility model spirit, still belongs to the scope that the utility model is contained.
Claims (2)
1. the bullet ripple with spongy layer, be horizontally set in the basin frame of loud speaker, the disk that You Yu center voice coil loudspeaker voice coil is corresponding forms, and section is provided with wave structure, include tissue layer, it is characterized in that: the tissue layer of this bullet ripple is mainly made up of upper and lower two fabric layers and middle spongy layer; Described spongy layer is connected with adhesive-layer, or embedding is provided with wire bar or conducting film.
2. the bullet ripple with spongy layer according to claim 1, is characterized in that: described spongy layer is for being spaced apart and arranged in whole or in part between levels tissue layer.
