The shape of the full sound speaker is based on the ordinary moving coil loudspeakers, as for the internal structure, the dust cover in the middle of the loudspeaker cone is changed to a pronunciation die The technical proposal is: the aluminium high pitch pronunciation die replaces the dust cover in the in the middle of the loudspeaker cone; the innovations: first, the bass and median tone produced by the voice coil stand drives the vibration of the loudspeaker cone, second, high pitch produced by the voice coil stand simultaneously drives the vibration of the aluminium pronunciation die in the middle of the loudspeaker cone, third, the aluminium pronunciation die becomes the dust cover of the loudspeaker. The utility model has the advantages of realizing the function of broadband election-acoustic conversion technically and providing a single voice coil, low cost, broadband (high, median and bass voice) moving coil, coaxial full sound speaker for color television, sound box of sound equipments, sound box in computers, sound box in cars, ballrooms, cinemas and palaestras.
Description
One. technical field:
The utility model belongs to the electroacoustic apparatus class.
The utility model relates to the full sound of a kind of broadband loud speaker, particularly relate to a kind of use metallic aluminum material as high pitch pronunciation modular substitution diffuser middle part dust cover, doing like this and technically can realize loud speaker broadband electroacoustic translation function, is a kind of single-tone circle coaxial full sound loud speaker of broadband (high, medium and low sound) moving-coil type cheaply.
Two. technical background:
At present, the electrodynamic type moving-coil speaker, a loudspeaker unit can not be realized broadband electroacoustic translation function, common way is three loud speakers of high, medium and low sound to be installed realize whole tone electroacoustic translation function frequently in a sound box; It is three loudspeaker units of high, medium and low sound to be installed combine and realize coaxial whole tone electroacoustic translation function frequently in a loud speaker body that some wideband loud speakers are also arranged, and does cost cost height like this; The utility model is intended on the basis of common electrical dynamic formula moving-coil speaker, the dust cover at former diffuser middle part is become the pronunciation mould, just can realize loud speaker broadband electroacoustic translation function through on so simple renovation technique, it can provide a kind of single-tone circle coaxial full sound loud speaker of broadband (high, medium and low sound) moving-coil type cheaply for the audio amplifier in colour TV, the stereo set, computer audio amplifier, automobile audio amplifier, dance hall movie theatre, conference hall, stadiums.
Three. the utility model content:
The utility model selects for use a kind of metallic aluminum material as high pitch pronunciation modular substitution diffuser middle part dust cover, and its shape is on the basis of common coil-moving speaker, and internal structure becomes the pronunciation mould with the dust cover at diffuser middle part.Technical essential is the dust cover with the diffuser middle part, changes into metallic aluminum material as high pitch pronunciation modular substitution diffuser middle part dust cover; Its innovative point: the one, the loudspeaker voice coil frame is driven the middle bass that the diffuser vibration produces audio frequency, the 2nd, the metallic aluminum material pronunciation mould that the loudspeaker voice coil frame is driven simultaneously the diffuser middle part again vibrates the high pitch that produces audio frequency, the 3rd, metallic aluminum material pronunciation mould also becomes the dust cover of loud speaker, and the 4th, do voice coil loudspeaker voice coil of technical needs like this and loud speaker broadband electroacoustic translation function just can be realized in one group of permanent-magnet component unit.After feeding the audio power signal code in the loudspeaker voice coil, the low-and high-frequency vibration that changes, the metallic aluminum material pronunciation mould that goes to drive diffuser and cone middle part produces mechanical oscillation, thereby make the whole tone vibration of radio cone paper basin assembly, tone currents is converted into the wideband sound wave, plays the effect of the full acoustic-electric sound of loud speaker function conversion.
(1). the technical solution of the utility model:
1. technical scheme is: be intended on the external shape approachingly basically with common moving-coil speaker, but on its internal structure the dust cover at diffuser middle part become the pronunciation mould and the dust cover of holding concurrently.
2. technical characterictic is: select for use a kind of metallic aluminum material as high pitch pronunciation modular substitution middle part dust cover.
3. concrete scheme is: removed the dust cover at diffuser middle part, changed into the high light gravity die material of metal (or nonmetal) thin type of metallic aluminum material or other high pitch vibration sensitivity as high pitch pronunciation modular substitution diffuser middle part dust cover.
4. key technology is: its internal structure is that outer the linking to each other with diffuser through the side face of cylinder of loudspeaker voice coil frame bonded together, and the cross section, termination (anchor ring) of loudspeaker voice coil frame is linked to each other with special metallic aluminum material high pitch pronunciation inner die surface to bond together.So just can realize the whole tone frequency vibration of radio cone paper basin assembly, this is the core of technical solutions of the utility model.
5. the technical solution problem is: combine closely because of being designed to loudspeaker voice coil (frame) unit and diffuser and dust cover, its vibration processes is: be subjected to the driving of permanent magnet assembly unit and produce vibration----voice coil unit drives cone and dust cover vibrates the elastic damping ring vibration that-----cone drives the cone outside together when voice coil loudspeaker voice coil feeds tone currents; Doing technical realization loud speaker electroacoustic like this changes wide band principle and is: when the tone currents of loudspeaker voice coil coil input is in high band, have only voice coil loudspeaker voice coil (frame) to drive pronunciation mould (dust cover) vibration, produce high pitch, because the cone material softness, dither is inoperative to it; When the tone currents of loudspeaker voice coil coil input is in Mid Frequency, there is voice coil loudspeaker voice coil (frame) to drive the cone vibration, produce middle pitch, because pronunciation mould (dust cover) material is gently hard, middle frequency vibration is inoperative to it; When the tone currents of loudspeaker voice coil coil input is in low-frequency range, there is voice coil loudspeaker voice coil to drive all vibrations together of dust cover, cone, elastic damping ring, produce bass, because pronunciation mould (dust cover) material is gently hard, low-frequency vibration is more inoperative to it.So the voiced process of full sound loud speaker is: when voice coil loudspeaker voice coil is in dither, have only pronunciation mould (dust cover) pronunciation, in voice coil loudspeaker voice coil is in, have only the cone pronunciation during frequency vibration, when voice coil loudspeaker voice coil is in low-frequency vibration, then have cone and elastic damping ring to vibrate together and send bass; So just can solve the single-tone circle broadband electroacoustic transfer problem of loud speaker.
(2). the utility model mainly is achieved as follows function:
1. can realize the broadband electroacoustic translation function of coaxial loudspeaker.
2. because of loud speaker has only a voice coil loudspeaker voice coil, then the permanent magnet unit assembly also only needs one group and gets final product.
3. loud speaker low cost of manufacture.
4. loud speaker also can be designed as internal magnetization and two kinds of series of external magnetic type.
5. the utility model can the design power size, the type of all size of overall dimensions size.
6. the utility model can design the loud speaker permanent magnet and is made up of common permanent magnet, also can make the full sound of high sensitivity loud speaker by the high ferromagnetism permanent magnet of rare-earth permanent magnet Nd-Fe-B permanent magnetic class.
7. the utility model can directly have common coil-moving speaker to change former dust cover becomes the full sound of coaxial broadband loud speaker for the pronunciation mould.
