Claims

[Scope of utility model registration request]

A handset/receiver structure in which a fixing ring is arranged on the outer periphery of a vibrating body, and a handset or a transmitter is fixed to a housing part of a handset cover, the handset or transmitter comprising a fixing ring and covering at least the front side of the vibrating body with an outer cover. In this case, a receiver part is provided on the peripheral edge of the bottom surface of the accommodating part of the handset cover to directly support the fixing ring part of the handset or transmitter, and this receiver has a recessed part on the inside 5 or outside of the part. A transmitter/receiver structure characterized in that a sealing rubber ring having a thickness greater than the depth of the recess is inserted into the recess.
