Document Type and Number:
WIPO Patent Application WO/2012/039491
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a headset for a helmet which transmits audio signals using bone conduction, and which transmits audio signals even when not using bone conduction. A headset for a helmet (2) for transmitting audio signals to a user (U) wearing a helmet (1) comprises: a bone conduction oscillator (4) which receives the audio signals and emits audio oscillations; an arm part (5) which has the bone conduction oscillator (4) on the leading end side thereof; and an attachment part (6) which attaches the base end side of the arm part (5) on the outer side of the crown (11) of the helmet (1) in a rotatable manner. The bone conduction oscillator (4) is brought into contact with either the head portion of the user (U) or the outer side of the crown (11), depending on the angle of rotation α of the arm part (5). The audio signals are thus transmitted to the user (U) when bone conduction is not used by using sounds emitted by the crown (11).
