Description

  The present invention relates to an ear speaker for listening to sound at an ear, and to a speaker provided with a function for preventing displacement of a wearing state.

  As an ordinary headphone, an overhead type that is worn so as to cover the ear via a headband, an ear-fit type that is worn by being hooked on the outer ear, an inner ear type that is directly inserted into the ear hole, etc. are known. Problems such as hearing loss (headphone deafness) due to listening to music for a long time with such headphones and accidents due to difficulty in hearing surrounding sounds occur.

  On the other hand, the present applicant has proposed the ear speaker of Patent Document 1. This ear speaker is composed of a speaker that outputs an audio signal and a headband that is attached to the speaker at a predetermined distance from the ear hole of the listener, and the speaker is directed to the ear hole of the listener in the attached state. It is movably attached to the mounting part. According to this ear speaker, since sound can be output from a position away from the ear hole by a predetermined distance, damage to the eardrum can be greatly reduced and headphone deafness can be prevented, and the ear is not blocked. Ambient sounds are easy to hear, ensuring safety.

  However, this ear speaker is only lightly impacted because the wearing state is only maintained by tightening to the head by the elastic force of the headband and hooking on the upper part of the ear by the ear hooking part formed on the headband. There was a problem that the speaker was displaced and the left and right volume balance was lost, making it impossible to hear the sound.

  Patent Document 2 has been proposed as a device for preventing such displacement of headphones. In this headphone, an ear hooking member that is pressed against the back of the ear is slidable with respect to the headband, and the ear hooking member is slid in close contact with the headband while the headphone is attached, so that the ear is in the headband. It is clamped between the ear hooking part and the ear hooking member to obtain a mounting posture that is difficult to shift.
