Electroacoustic transducer and manufacturing method thereof

摘要

An electroacoustic transducer comprises flexible strips and a shell, wherein the shell is formed of a first sub shell which is fixedly bonded to a second sub shell, the first sub shell is provided with a bonding surface for being bonded to the second sub shell, the flexible strip is bent to form a bent portion at the bonding surface; the second sub shell is provided with a dodging structure for dodging the bent portion. Its manufacturing method comprises: performing injection molding on the first sub shell from the bonding portions of the elastic strips; performing injection molding on the second sub shell; fixedly bonding the first sub shell with the second sub shell, wherein the flexible strip is bent to form the bent portion from the bonding surface at the end part of the first sub shell.

主权项

1. An electroacoustic transducer comprising a flexible strip and a shell, the flexible strip configured for electrically connecting internal circuitry with external circuitry of the electroacoustic transducer, the electroacoustic transducer is characterized in that:
the shell is ring-shaped and comprises a first sub shell and a second sub shell which are fixedly bonded to each other; a part of the flexible strip is bonded to the first sub shell by injection molding, the first sub shell is provided with a bonding surface at its one end close to the second sub shell, the bonding surface being bonded to the second sub shell, the flexible strip projects above the bonding surface and is bent at the bonding surface to form a bent portion; and the second sub shell is provided with a dodging structure at a position corresponding to the bent portion, which is used for dodging the bent portion, and the bent portion is inside an edge of the shell.
