Abstract
The invention discloses a method for manufacturing a multilayer piezoelectric loudspeaker vibrator, and relates to the technical field of loudspeakers. The method comprises the following steps: 1, performing wet grinding on piezoelectric ceramic powder, adding an adhesive into the ground piezoelectric ceramic powder, then manufacturing a tape-casted blank by adopting a tape casting process, and spraying the outer surface of the tape-casted blank with a sintering paint; 2, processing the tape-casted blank in step 1 into single ceramic sheets by adopting a laminated sintering process, and forming piezoelectric sheets from the single ceramic sheets; 3, gluing the piezoelectric sheets layer by layer by adopting a gluing process according to a method of connecting external electrodes to obtain N layers of piezoelectric sheets, heating and curing the N layers of piezoelectric sheets to obtain an integrated piezoelectric sheet, setting with a setting agent, and performing high-temperature sintering after setting; and 4, gluing the sintered piezoelectric sheet with a metal sheet, and pressing with a press, thus obtaining the N-layer piezoelectric loudspeaker vibrator. The method can improve the quality of a product, and is convenient to use, simple and convenient in operation and high in efficiency.
Description
Technical field
The present invention relates to loudspeaker techniques field, be specifically related to the manufacture method of a kind of multilayer piezoelectric speaker oscillator.
Background technology
Speaker is the energy transducer that a kind of the signal of telecommunication is changed into acoustical signal, the good and bad shadow to tonequality of the performance of speaker
Ring the biggest.Speaker is a device the weakest in stereo set, and for acoustics, it be again one the heaviest
The parts wanted.Speaker of a great variety, and price differs greatly.Audio frequency electric energy passes through electromagnetism, piezoelectricity or electrostatic effect, makes
Its cone or diaphragm vibration the air with surrounding produce resonance (sympathetic response) and send sound.
Low-grade plastic loudspeaker box, because its casing is thin, cannot overcome resonance, can say (also have the plastics that part designs without tonequality
Audio amplifier will be far better than wooden acoustic box inferior)；Wood cabinet reduces the sound dye that casing resonance is caused, and tonequality is generally better than
Plastic loudspeaker box.
Generally multimedia loudspeaker box is all double unit two divided-frequency designs, and a less speaker is responsible for alt output,
And another bigger speaker is responsible for the output of middle bass.
Select audio amplifier and be considered as the material of the two loudspeaker: the voice unit of active multimedia loudspeaker boxes is existing based on soft top dome
(the titanium film top dome etc. in addition with for simulating source of sound), it matches with digital tone source and can reduce the stiff sense of high-frequency signal,
Give gentle, smooth, fine and smooth sensation.Multimedia loudspeaker box is existing with soft balls such as the preferable cortina of quality and lower-cost PV films
That pushes up is in the majority.
Existing multilayer piezoelectric speaker oscillator easily delamination, its poor product quality during fabrication.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of multilayer piezoelectric speaker oscillator
Manufacture method.
In order to solve the problem existing for background technology, the manufacturer of a kind of multilayer piezoelectric speaker oscillator of the present invention
Method, it comprises following method:
Step one: piezoelectric ceramic powder carries out wet grinding, adopts after adding binding agent in piezoelectric ceramic powder after grinding
Curtain coating blank is prepared, at the outer surface spray sintering paint of curtain coating blank by casting molding processes；
Step 2: the curtain coating blank in step one uses lamination sintering process be processed preparing single ceramic to prolonging blank
Sheet；And by its piezoelectric patches；
Step 3: use adhesion process, the method that connected by outer electrode by piezoelectric patches is the most bonding obtains N shell piezoelectric patches, by N
Layer piezoelectric patches forms integration after being heating and curing；And shaped by setting agent, carry out high temperature sintering after sizing；
Step 4: by piezoelectric patches and the metal bonding film of sintering, uses press to suppress simultaneously, prepares N shell piezoelectricity and raise one's voice
Device oscillator.
Present invention have the beneficial effect that the quality being easy to improve product, easy to use, easy and simple to handle, efficiency is high.
Detailed description of the invention
This detailed description of the invention adopts the following technical scheme that it comprises following method:
Step one: piezoelectric ceramic powder carries out wet grinding, adopts after adding binding agent in piezoelectric ceramic powder after grinding
Curtain coating blank is prepared, at the outer surface spray sintering paint of curtain coating blank by casting molding processes；
Step 2: the curtain coating blank in step one uses lamination sintering process be processed preparing single ceramic to prolonging blank
Sheet；And by its piezoelectric patches；
Step 3: use adhesion process, the method that connected by outer electrode by piezoelectric patches is the most bonding obtains N shell piezoelectric patches, by N
Layer piezoelectric patches forms integration after being heating and curing；And shaped by setting agent, carry out high temperature sintering after sizing；
Step 4: by piezoelectric patches and the metal bonding film of sintering, uses press to suppress simultaneously, prepares N shell piezoelectricity and raise one's voice
Device oscillator.
The above, only in order to technical scheme to be described and unrestricted, those of ordinary skill in the art are to this
Other amendment or equivalent that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
All should contain in the middle of scope of the presently claimed invention.
