Title:
ELECTROACOUSTIC TRANSDUCER UNIT
Document Type and Number:
Japanese Patent JP3444450
Kind Code:
B2
Abstract:
PURPOSE: To connect a terminal of an electroacoustic transducer unit and a terminal of a telephone handset of its housing electrically without soldering by making elastically a chevron bent part of a contact piece connected to a case in contact with a terminal of an opposite terminal board of the housing.
CONSTITUTION: A contact member 5 whose mount seat 51 is fixed to a case of an electroacoustic transducer driver 1 acts like a lead wire. That is, a chevron bent part 53 formed to be a contact of the contact member to be soldered to a solder terminal of the case of the electroacoustic transducing driver 1 is made elastically in contact with a terminal of an opposite terminal board provided in the housing to connect electrically the soldering terminal and the terminal of the opposite terminal board. Since a tip 54 of the contact member 5 is supported in slidable contact with an outer face of the case, a contact pressure between the chevron shaped bent 53 and the terminal of the opposite terminal board is increased to enhance the contact reliability.
