Description
Technical field
The utility model relates to earphone field, particularly relates to a kind of paper substrate vibrating diaphragm of earphone horn.
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.
As shown in Figure 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.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.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 tiffany 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 is to provide a kind of rigidity, and internal damping is also higher simultaneously preferably, thus can reduce the paper substrate vibrating diaphragm of the earphone horn of diaphagras.
To achieve these goals, the paper substrate vibrating diaphragm of a kind of earphone horn of the present utility model, comprises the paper substrate vibrating diaphragm body of taper, and described vibrating diaphragm body comprises the larger top of radius and the less bottom of radius; Described vibrating diaphragm body is provided with multiple indent, in multiple described indent, is respectively equipped with aluminium base Rhizoma Sparganii strip reinforcement; Be coated with thermosetting glue-line in the side of described vibrating diaphragm body, described reinforcement is between described thermosetting glue-line and described vibrating diaphragm body, and described reinforcement is encapsulated in described indent by described thermosetting glue-line.
Described reinforcement comprises initial the first reinforcement extended to described bottom from described top, and from described bottom initial the second reinforcement extended to described top, described first reinforcement and described second reinforcement interval in the circumference of described vibrating diaphragm body is arranged.
The extension path of described reinforcement is helical form.
The thickness on the top of described vibrating diaphragm body is less than the thickness of bottom.
Described first reinforcement is three, and the circumference of described vibrating diaphragm body is evenly arranged; Described second reinforcement is three, and the circumference of described vibrating diaphragm body is evenly arranged; Described first reinforcement is identical with the hand of spiral of described second reinforcement.
Adopt technique scheme, the paper substrate vibrating diaphragm of earphone horn of the present utility model, because paper substrate has higher internal damping, therefore, it is possible to reduce the diaphagras of vibrating diaphragm as far as possible, on vibrating diaphragm body, be coated with thermosetting glue-line simultaneously, can film strength of shaking be improved, and to the vibrating diaphragm body of paper substrate, there is moisture-proof role; Aluminium base Rhizoma Sparganii strip reinforcement is set between thermosetting glue-line and vibrating diaphragm body, effectively can improves the rigidity of vibrating diaphragm; Reinforcement is that aluminium base material sole mass is lighter, be set to Rhizoma Sparganii strip simultaneously, there is anti-twist and bending resistance preferably, can directly prevent from when producing can being fixed by coating thermosetting glue-line in indent, technique is simple, and the setting of indent structure simultaneously also has the effect of gaining in strength to the vibrating diaphragm body of paper substrate.
