Description
The utility model relates to a kind of improved loud speaker, particularly be a kind of in the coaxial full frequency speaker of magnet steel double magnetic circuit.
Loud speaker is a converter that the audio-frequency electric signal is become sound.Because people's ear audition scope reaches 20HZ-17KHZ, so can the smooth and little distortion of frequency response curve sound in this frequency range exactly to the requirement of high-fidelity loudspeaker.But because the structure that ventional loudspeakers is made limitation, single loud speaker can only be at high frequency sounding in a certain segment limit of low frequency, so the division of labor of high and low frequency segmentation sounding occurred.Tweeter generally is responsible for the sounding of 3KHZ～20KHZ, woofer is served as the sounding of 20HZ～3KHZ, the required signal of telecommunication is distributed by frequency divider, make the basic wave and the high order harmonic component of same sound send from diverse location respectively thus, the deviation that distance and phase place have occurred, the definition and the location sense of sound have been influenced, so produced coaxial full frequency speaker, attempt these high and low two pronunciation unit are installed on same the sound wave emission axis, reach the effect of coaxial concurrent sounding.And domestic public coaxial full frequency speaker structure is undesirable at present, and manufacturing process is complicated, can not reach better hearing effect or workmanship and be difficult for reliable and stable.
In view of above reason, the purpose of this utility model is in order to overcome above deficiency, and a kind of rational in infrastructure, manufacturing process is simple, workmanship is reliable and stable, hearing effect is good coaxial full frequency speaker of interior magnet steel double magnetic circuit is provided.
The purpose of this utility model is achieved in that the utility model comprises the basin frame, be loaded on the bass cone in the basin frame, play ripple, it is characterized in that having in the loud speaker magnetic conduction cup that is connected with the basin frame, conducting magnetic column stretches in the magnetic conduction cup and magnetic conduction cup tight fit, the magnet of being made by alkene soil high magnetic force magnet steel that is arranged in the magnetic conduction cup is contained on the conducting magnetic column, magnetic guiding loop is contained on the magnet and forms the required magnetic circuit of high pitch with conducting magnetic column and become the required magnetic circuit of bass with magnetic conduction is cup-shaped, tweeters diaphragms is connected with magnetic guiding loop, the high pitch coil that is connected with tweeters diaphragms is arranged in the gap between conducting magnetic column and magnetic guiding loop, with play bass coil that ripple is connected and be arranged in gap between magnetic conduction cup and magnetic guiding loop (referring to Fig. 1, Fig. 2), alkene soil high magnetic force magnet steel can be selected Nd Fe B alloys for use, and the tweeters diaphragms material can be cortina, also can be metal film or special membrane.
Above-mentioned magnet is shaped as cylindrical alkene soil high magnetic force magnet steel by many pieces to be formed, and evenly distribution is fixing along the conducting magnetic column periphery for many pieces of alkene soil high magnetic force magnet steel, (referring to Fig. 1, Fig. 2).
The height and the equal diameters (referring to Fig. 1, Fig. 2) of above-mentioned alkene soil high magnetic force cylinder magnet steel.
Annulus between above-mentioned tweeters diaphragms and the bass coil has the bugle tube (referring to Fig. 1) that is used for the high pitch diffusion that is contained on the magnetic guiding loop, and the bugle public address is the ideal style that high pitch is propagated, and the bugle tube combines with the taper cone, makes that the radiation of high pitch is even more ideal.
Be connected with the foam (referring to Fig. 1) that is positioned at tweeters diaphragms on the above-mentioned conducting magnetic column.
Above-mentioned tweeters diaphragms be shaped as protruding sphere (referring to Fig. 1).
Above-mentioned tweeters diaphragms is for being shaped as concave ball shape (referring to Fig. 3).
According to the characteristics of alkene soil magnet steel, magnet size ratio and structure are by the minimum magnet steel decision of the strongest magnetic force.It is fixing to adopt many pieces of cylindrical magnet steel evenly to distribute along the conducting magnetic column periphery, is combined to form in one and adorns magnet, and the magnet steel height equals diameter, has reached minimum cost, and the best is used, and has solved the manufacturing difficulty and the expensive problem of circulus alkene soil magnetic.Magnetic guiding loop and center conducting magnetic column, magnetic conduction cup and magnetic guiding loop constitute high pitch coil and two required magnetic circuits of bass coil respectively, reasonable distribution by structure member, make the high pitch coil drive spherical vibrating membrane of high pitch and bass coil promotion bass cone, coaxial full range sounding.
The utility model is rational in infrastructure, and manufacturing process is simple, and workmanship is reliable and stable, and hearing effect is good, favorable expandability.Below the general bore of high pitch part is 1 ", can be designed to 0.75 more than " following or 1.5 " as special requirement, that the bass bore can be decided to be is commonly used 6.5 ", 8 ", but according to audio amplifier design needs, can be as small as 5 ", also can be greater than 10 " more than.The frequency response of this loud speaker can be satisfied the requirement of 20HZ～20KHZ fully, and technical indicators such as sensitivity, the distortion factor are not less than general high-fidelity loudspeaker.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a bugle coaxial full frequency speaker structural representation in magnet steel double magnetic circuit ball top in the utility model.
Fig. 2 is the magnet steel distribution map.
