The connector includes: a support for supporting the sound emitter so that the sound emitter is rotatable in a predetermined rotation range including a reference position; a restoring portion for applying a restoring force on the sound emitter for urging the sound emitter to return to the reference position; and a switcher for switching a state in which the restoring force acts on the sound emitter and a state in which the restoring force does not act on the sound emitter.
