Wireless headphone with a spring-biased activating power switch
First Claim
1. A headphone comprising:
- a headphone unit including a switch for switching an operation state of said headphone;
a supporting member to which said headphone unit is attached;
a substantially U-shaped headband, said headband having said supporting member slidably attached to one end thereof, and said headband being flexibly deformable for pressing said headphone unit against a listener'"'"'s ear when the listener wears said headband on the head, wherein said switch is switched by said headband when said headband slides toward and away from said supporting member; and
a spring-biasing member connected between said supporting member and said one end of said headband, said spring-biasing member for spring-biasing said supporting member in a direction of drawing said supporting member towards said headband, wherein a frictional force generated between said supporting member and said headband when the listener wears said headband on the head is substantially equal to a spring-biasing force of said spring-biasing member.

Abstract
A headphone like a cordless headphone including a pair of headphone units, a pair of supporting members, a headband and a pair of spring-biasing members. The headphone units are attached to one end of said supporting members. The headband is shaped in a substantially U-letter in cross section. When the listener wears the headband on the head, the headband is flexibly deformed to press the headphone units against the listener'"'"'s ears. A pair of spring-biasing members are disposed between the supporting members and the headband. The spring-biasing members spring-bias the supporting members in the direction in which the supporting members are contracted relative to the headband. Frictional forces generated between the supporting members and the headband under the condition that the listener wears the headband on the head are substantially equal to the spring-biasing forces of the spring-biasing members.
