Description
Technical field
The utility model relates to a kind of loadspeaker structure; Particularly about a kind of loadspeaker structure with outer rim vibrating diaphragm; Wherein this outer rim vibrating diaphragm ring outer rim of establishing and being engaged in the central vibrating diaphragm of a side on the voice coil tube, wherein preferable Microspeaker and the earphone of being used for of this loadspeaker structure.
Background technology
Loud speaker is a kind of electroacoustic transducer, and it is to see through physical effect to convert electrical energy into acoustic energy.Physical effect according to different electroacoustic conversions can be divided into polytype with speaker area, like electromagnetic loudspeaker, piezo-electric loudspeaker, condenser loudspeaker or dynamic speaker or the like.In various loud speakers, functional and of a great variety because of the dynamic speaker structure is simpler, use and popularize, be the main flow of loud speaker exploitation at present and production.
The basic structure of loud speaker can be divided into vibrational system, magnetic circuit system and auxiliary system three parts by the difference of its each several part effect.Vibrational system mainly contains voice coil tube, voice coil loudspeaker voice coil and high bass vibrating diaphragm or the like; Magnetic circuit system then comprises permanent magnet, pole piece and yoke or the like; Auxiliary system then contain with vibrational system and magnetic circuit system consist of one outside framework, voice coil loudspeaker voice coil draw lead, electricity circle or the like.
The operation principle of loud speaker is the variation that receives force direction because of current strength and voice coil loudspeaker voice coil, makes voice coil loudspeaker voice coil vibration back and forth in magnetic air gap, the cycle of its vibration or frequently rule equal the cycle of input current or rule frequently, the amplitude of vibration then is proportional to the power of each snap electric current.Because high bass vibrating diaphragm is fixed on the voice coil tube, therefore be located at voice coil loudspeaker voice coil on the voice coil tube and can drive high bass vibrating diaphragm and make up-down vibration, vibrate outside radiative acoustic wave through vibrating diaphragm, thereby realize the conversion between the electroacoustic ability.
Wherein, softer like diaphragm materials, can bear bigger amplitude, performance can be arranged during bass preferably, and,, but can make high pitch reach effect preferably though it is little then can to bear amplitude like diaphragm materials rigidity comparatively; If so select for use the material that is fit to the bass performance as vibrating diaphragm then can sacrifice the performance of loud speaker high pitch, otherwise, as select the material that is fit to high pitch for use, then can make bass can't reach effect preferably.
In addition; This high bass vibrating diaphragm engages normally with glue for it with voice coil tube, but since the face of this high bass vibrating diaphragm be vertical angle with this voice coil tube face and engage, so less owing to contact area when it engages; So that both are difficult for glutinous tight; And if the concentration of glue is not good or be not have gluing appropriate, then can causes the characteristic of loud speaker and stability not good, and can cause conduction loss.
In view of above-mentioned shortcoming, this creator is through long-term observation and thinking, and testing experiment repeatedly, proposes the utility model finally.
Summary of the invention
The utility model technical problem to be solved is: to the deficiency of above-mentioned prior art, the loadspeaker structure that provides a kind of Microspeaker and earphone to use.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: the loadspeaker structure that a kind of Microspeaker and earphone are used; Be characterized in: it comprises housing, magnet assembly, voice coil tube, central vibrating diaphragm, reaches the outer rim vibrating diaphragm, and this housing can be used as the support of whole loud speaker; This magnet assembly is made up of pole piece, magnet and yoke; This voice coil tube is positioned at this magnet assembly top, and ring is established voice coil loudspeaker voice coil on this voice coil tube; This central authorities' vibrating diaphragm is located at a side of this voice coil tube; The outer rim that this central authorities' vibrating diaphragm was established and be engaged in to this outer rim vibrating diaphragm ring.
In the loadspeaker structure of the utility model, this central authorities' vibrating diaphragm and this voice coil tube can be identical material, and the structure that is one of the forming.
In the loadspeaker structure of the utility model; Wherein can be equipped with the bullet ripple between this voice coil tube and housing; Play the effect that ripple can support the location to tool in the vibrational system of loud speaker; And can reduce this voice coil loudspeaker voice coil and this voice coil tube when the bass output amplitude is big by the installing of this bullet ripple, be difficult for friction or clash into this magnet assembly and cause different sound to produce.
The loadspeaker structure of the utility model; Wherein this outer rim vibrating diaphragm ring is established and is engaged in the outer rim of central vibrating diaphragm with glue, this glue only need can central authorities' vibrating diaphragm and the certain gluing of outer rim vibrating diaphragm get final product, need not consider its concentration; And more or less freely because of the gluing mode, be difficult for causing the gluing construction not good.
The loadspeaker structure of the utility model, wherein should central authorities' vibrating diaphragm and the material of this voice coil tube be selected from (but being not limited to) PEI (PEI), PEN (PEN), PEEK (polyether-ether-ketone), PI (polyimide), PET (PET), titanium alloy, aluminium alloy or magnesium alloy.
The loadspeaker structure of the utility model, wherein the material of this outer rim vibrating diaphragm is selected from (but being not limited to) PEN (PEN), polyester fiber (PET fiber), silk cloth, cotton or PU (Polyurethane).
In the loadspeaker structure of the utility model, wherein the material of this housing is selected from (but being not limited to) soft iron, plastics or aluminium.
In the loadspeaker structure of the utility model, it can avoid dust to fall into the magnetic gap between this pole piece and this yoke further in being provided with dust cap again.
In the loadspeaker structure of the utility model; On this voice coil tube with voice coil line around and form voice coil loudspeaker voice coil, wherein the material of this voice coil line does not have restriction, known metal such as copper, copper cover aluminum all can be used; The voice coil line cross section is generally circle; But also can adopt difform cross section,, also can adopt the square-section as in order to make full use of the space of magnetic gap in response to different demands.
In the loadspeaker structure of the utility model, wherein the magnet in this magnet assembly can be selected known material for use again, like aluminium nickel cobalt material, Ferrite Material or rare earth element material.
By above-mentioned loadspeaker structure; Because this central authorities' vibrating diaphragm and this outer rim vibrating diaphragm are the different component that makes up each other; So can constitute with unlike material respectively; Can reach preferable high pitch performance by the central vibrating diaphragm that is constituted than the rigidity material during high pitch output; Bass output the time then can provide preferable bass output quality by the outer rim vibrating diaphragm that comparatively soft materials constituted, thereby can overcome in the known technology, and the high bass vibrating diaphragm that uses identical material to process only can present high pitch or bass and the defective that can't make the best of both worlds.In addition; Because in this loadspeaker structure, therefore the structure that this central authorities' vibrating diaphragm and this voice coil tube can be identical material and be one of the forming can overcome in the conventional loudspeakers structure; It is less that high bass vibrating diaphragm and voice coil tube face are the contact area that vertical angle engages, so that both are difficult for glutinous tight defectives.This loadspeaker structure can use in various types of loud speakers, and preferable can be used for uses in Microspeaker and the earphone.
