Abstract
The utility model relates to an elastic wave structure capable of preventing abnormal vibrations. The utility model is mainly characterized in that the upper side of an elastic wave is covered with elastic reinforcing pieces which can adopt various proper materials and shape into the shape of a minor circular ring, the shape of a large circular ring, or a sliver-shaped piece body corresponding to the radius of the elastic wave. The reinforcing pieces with the different shapes are respectively or simultaneously combined at the surface of the elastic wave, so the strength of the elastic wave is improved, and meanwhile, force can be uniformly exerted on all the directions of the elastic wave and abnormal vibrations of the elastic wave can be avoided.
Description
Technical field
The utility model relates to a kind of being used in loudspeaker or the title loud speaker, as the assembly of suspention purposes.
Background technology
Fig. 9 shows general typical moving-coil type horn structure, includes dynamical system, drum paper and suspension.Dynamical system wherein further includes: magnet A, last iron B, clearance C and voice coil loudspeaker voice coil D.Described bulging paper E is and is used for the vibrating diaphragm of mobile air, is generally taper or hemispheric sound basin.Suspension is then formed with outstanding limit structure by playing ripple F, is used for the orientation of responsible traction drum paper F to move.
The start principle of aforementioned loudspeaker is to generate an electromagnetic field when making electric current flow through voice coil loudspeaker voice coil, utilizes this electromagnetic field and the magnetic field that is located at the permanent magnet on the loudspeaker direction that meets at right angles, and makes the motion in the stressed gap between clearance C voice coil loudspeaker voice coil and magnet of movable coil.This mechanical force of being produced of motion makes that the bulging paper that is attached to voice coil loudspeaker voice coil produces vertically, motion oscillations up and down, thereby makes air vibration and send audio frequency and be sent to people's ear, reaches the purpose that sound-reducing confession people listens to.
The loudspeaker of other kind may have different structures, and only action principle is identical, and includes the bullet ripple at least.
Owing to play ripple mainly is the usefulness that is used for being responsible for hanging voice coil loudspeaker voice coil and drum paper, therefore, normally will play wave structure and be designed to have plural concentrically ringed crest and trough, that is section is the form of wave; Wavy shaped configuration allows the bullet ripple have similar function of keeping away the spring that shakes by this, also can support voice coil loudspeaker voice coil and drum paper simultaneously.Hence one can see that, and the elasticity and the intensity that play ripple also can directly have influence on the Oscillation Amplitude of bulging paper, thereby influence voice effect.
General bullet ripple is to adopt plane materiel that cloth makes after soaking resin treatment and oven dry, and is one-body molded and make with mould again; It is to utilize the yarn car to knit to form that described plane materiel is then finished, therefore, made bullet ripple, possibility have the situation of intensity inequality because of the difference of thread density, when causing the loudspeaker start, cause the undesired vibrations that play ripple, thereby influences the tonequality output of loudspeaker.
Summary of the invention
Play the wave structure possibility because the density variation of cloth body own in order to improve tradition, cause the structural strength inequality, thereby when the loudspeaker start, cause the undesired vibrations that play ripple and influence the disappearance of the tonequality output of loudspeaker, the utility model aims to provide a kind of structural design that can prevent to play the undesired vibrations of ripple.
Principal character of the present utility model, be to play wave surface in conjunction with reinforcing chip, this reinforcing chip can be an annular, or strip, and reinforcing chip has section and the wave-like that plays the complementation of ripple section, after making the reinforcing chip of annular or strip be incorporated into respectively or simultaneously to play on the ripple, promoted and the equilibrium bomb intensity of wave, reached the problem that prevents to play the undesired vibrations of ripple.
First technological means of the utility model can be designed to reinforcing chip directly go to the annular that the external diameter direction is extended a segment distance corresponding to playing within the ripple, uses that this reinforcing chip is incorporated into the surf zone of bullet ripple near internal diameter.
Second technological means of the utility model can be designed to reinforcing chip corresponding the bullet outside the ripple and directly go to the annular that internal diameter direction extends a segment distance, uses that this reinforcing chip is incorporated into the surf zone of bullet ripple near external diameter.
The 3rd technological means of the utility model can be designed to reinforcing chip the corresponding strip lamellar body that plays the radius of ripple, uses plural strip reinforcing chip is several radial location that equal angles is incorporated into the bullet ripple with distributing.
The 4th technological means of the utility model, be bigger annular reinforcing chip and less annular reinforcing chip to be incorporated into simultaneously and play the zone of wave surface near external diameter and internal diameter, and a plurality of strip reinforcing chips are incorporated into a plurality of radial location that play ripple, use the bullet wave structure that reaches more reinforcements.
The 5th technological means of the utility model is to utilize the described reinforcing chips of made such as cloth body, plastics, rubber or silica gel; Only, if when making with the cloth system, the yarn car of this cloth body is knitted the yarn car that direction must be different from this bullet ripple and is knitted direction, so just can reach and strengthen the effect that plays ripple.
Because the utility model mainly is to adopt adhesive agent as interface reinforcing chip to be incorporated into the bullet wave surface, therefore, during fabrication, can be positioned over cloth body and reinforcing chip in the mould simultaneously, when going out to play ripple to cloth is body formed, also reinforcing chip is incorporated into the bullet wave surface together, make very efficient activity of processing procedure of the present utility model, be able under the principle of optimum economic benefit, promote the mean intensity that plays ripple, undesired vibrations take place thereby prevent to play ripple.
