Abstract

A headset for a helmet transmits audio signals using bone conduction, and transmits audio signals even when not using bone conduction. A headset for a helmet for transmitting audio signals to a user wearing a helmet includes: a bone conduction oscillator which receives the audio signals and emits audio oscillations; an arm part which has the bone conduction oscillator on the leading end side thereof; and an attachment part which attaches the base end side of the arm part on the outer side of the crown of the helmet in a rotatable manner. The bone conduction oscillator is brought into contact with either the head portion of the user or the outer side of the crown, depending on the angle of rotation a of the arm part. The audio signals are thus transmitted to the user when bone conduction is not used by using sounds emitted by the crown.

Claims

1. A headset for a helmet which transmits an audio signal to a user wearing a helmet, comprising:

a bone conduction oscillator for generating audio oscillation upon receiving an audio signal;

an arm part with the bone conduction oscillator provided on its tip side; and

an attachment part for rotatably mounting a base end side of the arm part to an outer side of a crown of the helmet;

wherein switching is performed between a state where the bone conduction oscillator is in contact with the head portion of the user and a state where the bone conduction oscillator is in contact with the outer side of the crown according to an angle of rotation of the arm part.

2. The headset for a helmet according to claim 1, wherein:

the attachment part includes a supporting portion for rotatably supporting the base end side of the arm part and a fixing portion to be fixed to the crown; and

the supporting portion is detachably attached to the fixing portion.

3. A helmet, comprising the headset for a helmet according to claim 1.

4. A helmet, comprising the headset for a helmet according to claim 2.
