摘要：A cylindrical contact-type microphone, which relates to the technical field ofaudio devices, and solves the technical problem of inconvenient assembly of an existingcontact-type microphone. The microphone comprises a shell, and a circuit board (4), apiezoelectric ceramic sheet (2), a lower-stage connection plate (3) and a conductive polarring (5) which are mounted within the shell, wherein the shell is a two-section cylindricalconductive cylinder body, and a negative signal lower connection sheet of the lower-stage connection plate (3) is electrically connected to a step (13) at a joint portion of anupper cylinder section (11) and a lower cylinder section (12) of the shell; a bottom edgeof the conductive polar ring (5) is electrically connected to a positive signal lowerconnection sheet of the lower-stage connection plate (3); the piezoelectric ceramic sheet(2) is inserted into the shell, and positive and negative electrodes of the piezoelectricceramic sheet (2) are respectively connected to the positive signal lower connectionsheet and the negative signal lower connection sheet of the lower-stage connectionplate (3); a positive signal upper connection sheet of the circuit board (4) is electricallyconnected to an upper edge of the conductive polar ring (5); and an upper edge of theshell is bent inward and is electrically connected to a negative signal upper connection
sheet of the circuit board (4).
