Advantageous Effects of the present utility model is:
1, the utility model pastes thin film loudspeaker on other electronic display units such as existing computer, televisor or mobile phone, the function of sound equipment can be replaced, the thickness of wafer speaker is even thinner in millimeter rank, can bend, curling or folding, therefore be easy to be attached to body surface, or be hidden in interior of articles, it is integrated that realization unites two into one.So in the utility model, wafer speaker can be attached to display surface, because wafer speaker is transparent, do not affect the content shown by display, then make display when display video or image, can play sound simultaneously, add the practicality of display, make it more intelligent.And a traditional sound equipment compares with a film, the weight of wafer speaker alleviates greatly, further can reduce the volume and weight of display, increases the portability of electronic equipment.
2, wafer speaker described in the utility model uses nano metal wire material as conductive film, and make to form Ohmic contact between conductive film and vibration film, contact resistance reduces greatly.Relative to use macromolecule conducting material as conductive film, macromolecule conducting material resistance is large, and audio frequency field decay is strong, and electric field suffered by the core of vibration film can be caused weak, then whole loudspeaker sounding is uneven.And nano metal wire material can be coated on whole vibration film, and nano metal wire material conductive effect is good, can make the electric fields uniform suffered by whole vibration film, then vibrate also even, sound effect is better.
Known by experiment, conventional macromolecule conducting material, as pedot material, after contacting with vibration film, the square resistance of its surface of contact is 1000 Ω/mouth; Common metal material, the square resistance of its surface of contact is 10 Ω/mouth; And nano metal wire material, the square resistance of its surface of contact, no less than metal material, substantially reduces resistance, can improve the homogeneity of whole electric field, namely adds the homogeneity of wafer speaker sounding.Further, if directly smear metal material on vibration film, because the audio frequency characteristics of metal material self, release and the propagation of vibration film sound can be affected greatly, have influence on middle bass effect and become poorer, and metal nano silver wire material coating described in the utility model is on the one hand because good surface contact effect and electric conductivity, guarantee that vibration film is in energising situation, surface forms homogeneous electric field, realize good sounding effect, then obstacle is not caused to the release of sound on the other hand, obtain good sound transmission effect, it is best selection.
3, wafer speaker described in the utility model uses nano metal wire material as conductive film, nano metal wire material is better than other conductive metal film parts and is also, on microcosmic, nano metal wire material is that multiple nano level metal wire overlap joint forms, and Fig. 1 is the micromechanism schematic diagram of nano metal line.As shown in Figure 1, under the prerequisite not affecting its electric conductivity, have between nano metal line and have Micro porosity, so macroscopically, the transparent shape of nano metal line, this characteristic of nano metal line has the following advantages:
First, transparent conductive film is attached on the vibration film of transparent material, whole loudspeaker can be made to be transparence, be suitable for loudspeaker to be attached to the surface of any object and do not affect the form of object itself, preferablyly loudspeaker to be directly attached on image or video display apparatus, increase the scope of application of the present utility model, make the utility model have stronger practicality;
Secondly, after vibration film vibration is sounded, relative to traditional conductive material, the obstruction of nano metal wire material to sound that vibration film attaches reduces greatly, and better can discharge sound, the sound effect that loudspeaker film is sent is more excellent;
Again, bending effect and the pliable and tough effect of nano metal wire material are also better than traditional metal material, so the wafer speaker produced, are suitable for being attached to showing of any object, can bend as required, add practicality of the present utility model.
The character of the vibration material 4, in wafer speaker itself determines that it is better in medium-high frequency sounding effect.The utility model on the basis of existing technology, by increasing the method for microfabrication structure on insulation course or sound-emitting membrane, greatly strengthen the voice effect of wafer speaker.Tone quality improving layer is that the material all different with the material of vibration film and conductive film is made, after vibration film produces sound, its energy of vibration can be propagated to different directions, on its route of transmission, when existence can vibrate sonorific material, this material vibrates will be caused, because material is different, then the optimum frequency of vibration sounding is different, and microfabrication structure can produce resonance to bass, different microfabrication structures can increase the bass concussion effect of different frequency, enhance the frequency response range of wafer speaker, the sounding effect of wafer speaker at full frequency band can be improved.
5, the wafer speaker in the utility model also add insulation course, to prevent from, in use procedure, electric shock accidents occurs, and insulation course can arrange microfabrication structure, the resonance in acoustic transmission path can be increased, and filtering out high-frequency noise in the process, effectively improve tonequality, make sound softer.Simultaneously insulation course can available protecting conductive film material, prevents coming off of conductive material
6, wafer speaker described in the utility model also proposed a more excellent technical scheme, and namely sound-emitting membrane is thin film structure, and tone quality improving layer becomes with vibration film that checkerboard grid shape is spaced apart to link together.Such technical scheme, the technical scheme being attached to vibration film with tone quality improving laminating can reach the technique effect that close sound improves.But owing to being that tone quality improving layer and vibration film form sound-emitting membrane jointly, in a wafer speaker, the use amount of vibration film reduces greatly, and the prime cost of wafer speaker is just on vibration film, can reduce the manufacturing cost of whole wafer speaker like this.
