Claims

[Scope of utility model registration request]

In an electronic watch in which a clock mechanism and a battery are easily installed in a case and a lower case, a piezoelectric buzzer having a diaphragm with a contact piece integrally formed in a protruding position at a position corresponding to a printed pattern on a circuit board is mounted on the top. An electrode plate fixed to the case and made of a conductive elastic member and having one end in pressure contact with a battery electrode can be elastically deformed toward the other end of the electrode plate at a position corresponding to the piezoelectric element portion of the piezoelectric buzzer or toward the lower case. When the upper case and lower case are connected, the contact piece formed on the diaphragm of the piezoelectric buzzer and the printed pattern on the board are brought into pressure contact, and the piezoelectric element part of the piezoelectric buzzer and the A method for connecting a piezoelectric buzzer for an electronic watch, characterized by bringing the other end of the electrode plate into pressure contact.
