Abstract
The invention provides a piezoelectric ceramic flat loudspeaker vibrator and an installation structure thereof. According to the piezoelectric ceramic flat loudspeaker vibrator and the installation structure thereof, a piezoelectric ceramic transduction way is utilized, the piezoelectric ceramic vibrator is used for converting audio electrical signals into mechanical vibration signals, then a flat object such as a notebook computer, a tablet computer, and a panel, a rear cover plate, a screen and a support plate of a mobile phone is used for converting the vibration signals into sound signals, and therefore the functions of a flat loudspeaker are achieved, and good sound playing effect is achieved.
Description
Technical field
The invention belongs to the electro-acoustic transducer device technical field, be specifically related to a kind of piezoelectric ceramic panel speaker oscillator.
Background technology
Piezoelectric ceramic plate vibration loud speaker oscillator is a kind of by piezoelectric ceramic transducing mode, by flat board, realizes the electro-acoustic transducer device of panel speaker result of broadcast.
Conventional loud speaker, as cone loudspeaker, wafer speaker etc. generally need be packed it in the audio amplifier, could obtain sound result of broadcast preferably, its complex structure, volume is big, Heavy Weight.
Summary of the invention
The purpose of this invention is to provide a kind of piezoelectric ceramic panel speaker oscillator and mounting structure thereof, piezoelectric ceramic panel speaker oscillator, volume is little, and is in light weight, simple in structure, easy for installation.
Technical scheme of the present invention is: a kind of piezoelectric ceramic panel speaker oscillator, it is characterized in that by the multilayer piezoelectric ceramic twin lamella and draw lead and form, with lead the both positive and negative polarity of multilayer piezoelectric ceramic twin lamella is drawn, be oscillator, it is installed on the surface plate, can realizes the panel speaker function.
Wherein drawing lead can substitute with FPCB.
Multilayer piezoelectric ceramic twin lamella size range wherein: long 20～60mm, wide 2～10mm, thick 0.3～1.2mm.
The mounting structure of oscillator on flat board has a significant impact the loud speaker sounding effect, and the technical program has been stipulated cantilever type, intermediate supports, two end supports, direct smooth four kinds of oscillator mounting structure forms.
One end, 1/3～1/2 length of oscillator is fixed on the surface plate, and the other end is unsettled, and flying height 0.5～1.0mm forms the cantilever type mounting structure.
Each 1/5～1/4 length of oscillator two ends is fixed on the surface plate, and mid portion is unsettled, and flying height 0.3～1.0mm forms the two end supports mounting structure.
Oscillator directly is attached on the surface plate with double faced adhesive tape or glue, forms direct smooth mounting structure.
The present invention utilizes piezoelectric ceramic transducing mode, pass through piezoelectric ceramic vibrator, audio electrical signal is directly changed into mechanical oscillation signal, relend and help dull and stereotyped object, as the panel of notebook computer, panel computer, mobile phone, back shroud, screen, supporting plate etc., convert vibration signal to voice signal, realize the panel speaker function, obtain good sound result of broadcast.
