The present invention uses the technical scheme, the utility model discloses a basin frame structure is propagated to the both sides of vibrating diaphragm when vibrating diaphragm vibrations sound production back sound wave, and to the sound wave of propagating to basin frame one side, partly sound wave can be put up this bulk absorption by the basin, and outwards propagate in the gap that another part sound wave can pass between the adjacent splice plate, so these sound waves can not impel the vibrating diaphragm formation to cut apart the vibration because taking place to launch.
Description
Technical field
The utility model relates to receiver field, particularly relates to a kind of frame structure of receiver.
Background technology
Receiver is a kind of electronic product conventional in life.The tonequality of receiver is subject to the impact of many factors, such as the diaphagras of Loudspeaker diaphragm.For the vibrations of ripples, after a basin crystal is caused calmness, instill a water in central authorities, can find that the ripples evoked spread to surrounding, when ripples touch basin, can be reflected back, reflected wave can interfere the ripples still continuing diffusion.If with the rhythmical past middle position instillation water droplet that dropper continues, can evoke the ripples of the another ripple of a ripple, then produce the another wave reflection ripple of a ripple, these ripples are interfered mutually, and the whole water surface is active, and ripples are so not clear before.In fact, when electrodynamic loudspeaker works, also can run into such problem, after voice coil loudspeaker voice coil energising, become electromagnet, produce active force with permanent magnet, Continuous Drive vibrating diaphragm sounding.But this process can not be considered as simple piston movement, vibrating diaphragm is not rigid body completely, and during its motion, itself can produce deformation as the water surface.Waveform is propagated along by voice coil loudspeaker voice coil and vibrating diaphragm bonding place to surrounding and front end, and to when running into ring, ripple also can equally be reflected back by ripples, thus mutually interferes with other waveforms.It is more complicated that actual conditions spill ripples than water droplet, because driving frequency is much higher, changes also faster.But when frequency reaches certain value, vibrating diaphragm vibration of forming region because of the mutual interference of ripple.In experiment in middle school, have the experiment of " interference of ripple ", its experimental situations is a bit similar to the phenomenon that we mention, and can use for reference, so more more vivid, because we cannot take appearance when shaking vibration of membrane with camera.Vibrating diaphragm is divided into multiple region by invisible at different frequencies, and some adjacent domain oscillation phase place is also anti-phase each other.The local vibration in this one-tenth region, is just diaphagras.
When receiver works, voice coil loudspeaker voice coil is in vibration, and even receiver itself is all in vibration, and the gas inside and outside casing is to the jacking of vibrating diaphragm, and these all can finally occur generation effect to diaphagras.Existing receiver loudspeaker generally include frame base, iron core, magnet, voice coil loudspeaker voice coil, vibrating diaphragm, dust cap and play ripple.When after voice coil loudspeaker voice coil energising, become electromagnet, along with the change of signal, the magnetic field that electromagnet produces along with changing, can produce active force with magnet, Continuous Drive vibrating diaphragm vibrations sounding.After vibrating diaphragm vibrations sounding, sound wave is propagated to the both sides of vibrating diaphragm, according to sound transmission theory, for the sound wave propagated to frame side, when collision frame rear portion can be absorbed by frame, another part can be reflected by frame, and when sound wave dry penetrating will be occurred the sound wave that produces of the vibrations sounding follow-up with vibrating diaphragm after reflecting, form diaphagras.Segmentation vibrations are current can't be completely eliminated, and can only reduce as much as possible.Split distortion by simple knowledge, we are aware of the communication media of vibrating diaphragm as vibration, and physical characteristic itself also can have influence on the severe degree of diaphagras, and desirable material is exactly good rigidly and the higher diaphragm of internal damping.Good rigidly is deformation not easily, can rapid decay after the higher then vibration of internal damping, but to seem these two characteristics be opposed, actual conditions are materials of good rigidly, and internal damping is low, such as metal vibration diaphragm, the material that rigidity is poor, internal damping is high, such as vibrating diaphragm and paper substrate vibrating diaphragm.Therefore, the improvement that it may be necessary technology reduces diaphagras as far as possible, to avoid earphone tonequality serious distortion.
Utility model content
Therefore, the technical problems to be solved in the utility model provides a kind of structure by changing frame, to reduce frame to sound wave reflection, thus reduces the diaphagras of vibrating diaphragm, and then improves the frame structure of receiver tonequality.
To achieve these goals, the frame structure of a kind of receiver of the present utility model, comprises the frame body of taper, and described frame body comprises the larger top of radius and the less bottom of radius; Described frame body is that Z-shaped splice plate forms by multiple cross section, and each splice plate originates in described top and extends to described bottom, and adjacent splice plate overlaps setting mutually.
Described top is arranged at the inside of one first annular plate.
One second annular plate is arranged with in described bottom.
Adopt technique scheme, frame structure of the present utility model, when after vibrating diaphragm vibrations sounding, sound wave is propagated to the both sides of vibrating diaphragm, for the sound wave propagated to frame side, part sound wave can by frame bulk absorption, another part sound wave outwards can be propagated through the gap contiguous concatenation plate, and therefore these sound waves will impel vibrating diaphragm to form diaphagras because generation is launched; , because the cross section of splice plate is zigzag, and mutually overlap meanwhile, therefore ensureing that between contiguous concatenation plate under the apertured prerequisite of tool, the dust outside frame can also be avoided directly to enter inside frame affects tonequality.

Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, 3, the present embodiment provides a kind of frame structure of receiver, comprises the frame body 1 of taper, and described frame body 1 comprises the larger top of radius 11 and the less bottom 12 of radius; Described frame body 1 is that Z-shaped splice plate 100 forms by multiple cross section, each splice plate 100 originates in described top and extends to described bottom, adjacent splice plate 100 overlaps setting mutually, thus enable adjacent splice plate overlap have gap air is passed, and avoid frame having through hole or groove makes dust easily pass through.
Described top 11 is arranged at the inside of one first annular plate 2.
One second annular plate 3 is arranged with in described bottom 12.
Adopt technique scheme, frame structure of the present utility model, when after vibrating diaphragm vibrations sounding, sound wave is propagated to the both sides of vibrating diaphragm, for the sound wave propagated to frame side, part sound wave can by frame bulk absorption, another part sound wave outwards can be propagated through the gap contiguous concatenation plate, and therefore these sound waves will impel vibrating diaphragm to form diaphagras because generation is launched; , because the cross section of splice plate is zigzag, and mutually overlap meanwhile, therefore ensureing that between contiguous concatenation plate under the apertured prerequisite of tool, the dust outside frame can also be avoided directly to enter inside frame affects tonequality.
