Abstract
The utility model discloses a heat dissipation stable state piezoceramics drive piece, including substrate and piezoceramics wafer, the piezoceramics wafer attached in the substrate both sides, the substrate both ends are equipped with a plurality of arrow point connected in stars, the arrow point connected in star transversely set up arrange in on the substrate terminal surface, embedding fin in the arrow point connected in star, still be equipped with fixed lagging on the substrate terminal surface in the arrow point connected in star outside. In this way, the utility model discloses can improve piezoceramics drive piece stability and thermal diffusivity, increase of service life.
Description
Technical field
The utility model relates to piezoelectric ceramics driving piece field, particularly relates to a kind of heat radiation stable state piezoelectric ceramics driving piece.
Background technology
Piezoelectric ceramic piece is a kind of electrophonic musical element, piezoelectric ceramic dielectric material is put in the middle of two panels copper circular electrode, when connecting AC audio signal on two plate electrodes, can there are vibrations according to the large small frequency of signal and produce corresponding sound in piezoelectric patches, piezoelectric ceramic piece is made up of substrate and piezoelectric ceramic wafer.
But because substrate can generate heat in the process of conduction, and traditional piezoelectric ceramics driving piece poor radiation, thus cause piezoelectric ceramics driving piece temperature to raise, the situations such as deformation easily occur, and then impact uses, shorten useful life.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of heat radiation stable state piezoelectric ceramics driving piece, can improve piezoelectric ceramics driving piece stability and thermal diffusivity, increase the service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of heat radiation stable state piezoelectric ceramics driving piece, comprise substrate and piezoelectric ceramic wafer, described piezoelectric ceramic wafer is attached at described substrate both sides, described substrate two ends are provided with multiple arrowhead-shaped recess, described arrowhead-shaped recess is laterally offered and is arranged on described substrate end face, and described arrowhead-shaped recess is embedded in fin, and the substrate end face outside described arrowhead-shaped recess is also provided with fixing cage plate.
In the utility model preferred embodiment, described fixing cage plate compacting is wrapped in described substrate two ends, and the fixing cage plate of described substrate one end is in " [" type, the fixing cage plate of the described substrate other end is in "] " type.
In the utility model preferred embodiment, described fixing cage plate is copper sheet plate.
In the utility model preferred embodiment, described arrowhead-shaped recess is mutual spaced set side by side.
In the utility model preferred embodiment, described fin is aluminium chip.
The beneficial effects of the utility model are: the utility model embeds the arrowhead-shaped recess of aluminium chip by offering at piezoelectric ceramics driving piece two ends, arrowhead-shaped recess can prevent piezoelectric ceramics driving piece deformation, and aluminium chip has good heat sinking function, improve piezoelectric ceramics driving piece stability and thermal diffusivity simultaneously, increase the service life.
