Problems solved by technology

[0002] A piezoelectric speaker is a device that generates current through the piezoelectric effect of piezoelectric materials and transmits the current to the speaker to energize the speaker to produce sound. When installing a piezoelectric speaker, it is necessary to install the device to Fixed, when using thin piezoelectric sheets to generate power, since the amount of current generated by a single thin piezoelectric sheet is very limited, it is necessary to connect multiple thin piezoelectric sheets in series in the installation device to superimpose the current and increase the current intensity. It can then drive the speaker to produce sound, but when working, if a single thin piezoelectric sheet is damaged due to excessive pressure, it is easy to cause an open circuit at this position, and then the current generated by other piezoelectric sheets cannot Smooth flow to disable piezo speakers

Abstract

The invention discloses thin piezoelectric loudspeaker installation equipment, and the equipment structurally comprises a base, a pressing table, a loudspeaker socket and an installation block; the top face of the base is connected with the bottom face of the pressing table in a welded mode, the loudspeaker socket and the left side of the pressing table are integrally formed, and the installation block is embedded into the front face of the pressing table. The piezoelectric patches are mounted through the mounting block; when power generation is needed, the pressing table is pressed to generate current through pressure and output the current to the capacitor, so the loudspeaker inserted into the loudspeaker jack can generate sound; if one piezoelectric patch is damaged in the use process, the electromagnet can be started through the current generated by the other piezoelectric patches, and the broken piezoelectric material is pushed out by the electromagnet; meanwhile, the contact heads are pushed inwards through the inner push rod, so that the contact heads are in rapid mutual contact without rebounding, the current can continue to circulate, and the situation that the whole equipment cannot continue to operate due to damage of a single piezoelectric patch is avoided.
