Abstract
The utility model discloses a kind of frame of earphone horn of high-fidelity, comprise the foamed ceramics body of taper, described foamed ceramics body offers cellular hole.Adopt technique scheme, the earphone horn of high-fidelity 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, because foam ceramic material has good acoustically effective, major part sound wave can absorb by foamed ceramics body, therefore this part sound wave can not because generation launch and impel vibrating diaphragm formed diaphagras.
Description
Technical field
The utility model relates to earphone field, particularly relates to a kind of frame of earphone horn of high-fidelity.
Background technology
Earphone is a kind of electronic product conventional in life.The tonequality of earphone is subject to the impact of many factors, such as the diaphagras of earphone 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 speaker operation, especially during high power work, the parts of loud speaker self, comprise the parts that should not vibrate, such as voice coil loudspeaker voice coil, etc. reality also vibration, even loud speaker, itself all vibration, the gas inside and outside casing is to the jacking of vibrating diaphragm, and these all can finally occur generation effect to diaphagras.Such as shown in Fig. 1, the loudspeaker of earphone generally include frame 101, base 102, iron core 103, magnet 104, voice coil loudspeaker voice coil 105, vibrating diaphragm 106, dust cap 107 and play ripple 108.After voice coil loudspeaker voice coil 105 is energized, become electromagnet, along with the change of signal, the magnetic field that electromagnet produces along with changing, can produce active force with magnet 104, and Continuous Drive vibrating diaphragm 106 shakes sounding.After vibrating diaphragm 106 shakes sounding, sound wave is propagated to the both sides of vibrating diaphragm 106, according to sound transmission theory, for the sound wave propagated to frame 101 side, when collision frame 101 rear portion can be absorbed by frame 101, another part can be reflected by frame 101, as in Fig. 1 pointed by arrow, and when sound wave by will be follow-up with vibrating diaphragm 106 after reflecting the sound wave that produces of vibrations sounding there is dry penetrating, 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 by changing the structure of frame, to reduce frame to sound wave reflection, thus reduces the diaphagras of vibrating diaphragm, and then improves the frame of high-fidelity headphone loudspeaker of earphone tonequality.
To achieve these goals, the frame of a kind of high-fidelity headphone loudspeaker of the present utility model, comprises the foamed ceramics body of taper, and described foamed ceramics body offers cellular hole.
At described foamed ceramics body, the side of vibrating diaphragm is provided with layer of silica gel.
Described layer of silica gel and described foamed ceramics body gapless close contact.
At described foamed ceramics body, the side of vibrating diaphragm is provided with rubber layer.
Described rubber layer and described foamed ceramics body gapless close contact.
Adopt technique scheme, the frame of high-fidelity headphone loudspeaker 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, because foam ceramic material has good acoustically effective, major part sound wave can absorb by foamed ceramics body, therefore this part sound wave can not because generation launch and impel vibrating diaphragm formed diaphagras.

Embodiment
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 2, the present embodiment provides a kind of frame structure of high-fidelity headphone loudspeaker, comprises the foamed ceramics body 101a of taper, and described foamed ceramics body 101a offers cellular hole.
At described foamed ceramics body 101a, the side of vibrating diaphragm is provided with layer of silica gel or rubber layer 101b.
Described layer of silica gel or rubber layer 101b and described foamed ceramics body 101a gapless close contact.By described layer of silica gel or rubber layer 101b, the protection that ceramic material is certain can be given, make it not easily broken when unexpected generation is clashed into.
As shown in Figure 3, the utility model also provides a kind of loudspeaker of earphone, comprises frame 101, base 102, iron core 103, magnet 104, voice coil loudspeaker voice coil 105, vibrating diaphragm 106, dust cap 107 and plays ripple 108.Wherein iron core 103 and magnet 104 are fixed on base 102 and form magnetic circuit system, and described voice coil loudspeaker voice coil 105 upper end is fixed on vibrating diaphragm 106, and the other end is through the magnetic gap of magnetic circuit system.
Described frame 101 comprises the foamed ceramics body 101a of taper, and described foamed ceramics body 101a offers cellular hole.
