Bone-conduction speaker device

Abstract

A bone conduction loudspeaker is formed of a transmitter(5) for receiving a sound signal, converting the signal into an infrared ray output and transmitting the resulting signal, a sound receiver for receiving the infrared ray signal from the transmitter, whose character is forming a pad with a built-in bone conduction loudspeaker consisting a receiver(7), a bone conduction loudspeaker(2) and an elastic buffer member(3). The receiver demodulates the received signal into a sound signal, the bone conduction loudspeaker outputs the received and amplified sound signal as sound vibration, and the elastic buffer member supports the bone conduction loudspeaker on its surface to form the pad, wherein a plurality of light receiving sections(9) of the receiver are placed at end edges of the pad elastic buffer member at intervals. The invention makes no leakage of sound and does not restrict posture of the user, which makes highly reliable and excellent receiving of sound signal.

Description

technical field [0001] The present invention relates to a cushion device that can be used together with a pillow for listening to music through bone conduction, and more particularly, to a bone conduction speaker device that is improved for infrared sound signal input. Background technique [0002] In the past, as a way to listen to music and radio while sleeping, there was a method of putting speakers in the pillow, so that the listener could listen to the sound from the speaker installed under the surface covering material through the mesh of the pillow (see Japan Patent Document 1). There is also a headphone utilizing bone conduction (see Japanese Patent Document 2). [0003] Recently, a product such as Figure 10 As shown, the bone conduction speaker 72 is packed into the cushioning material 73 pillowed on the head, which can be used as a pillow 71 to listen to music while sleeping. Its composition is that a skin layer is integrally provided on the surface of polyureth...

Problems solved by technology

However, the anti-vibration body 75 is a bag in which a colloidal solution is sealed, so not only does the cost increase, but also the colloidal solution leaks out when the bag is broken due to impact or the like, polluting the covering body 4 and its surroundings.
