I: Prior Art 3 BACKGROUND OF THE INVENTION As a headphone, it is generally divided into a conventional earphone that is inserted into an external auditory canal to plug the ear, a bone conduction earphone that also plugs the ear, and a bone that can be used without being inserted into the external auditory canal. Conductive headphones. The earphones of the former are as described in the literature 1 (magnetic earphones) and the literature 2 (piezoelectric type). The latter's headphones are similar to those in the literature 3 (so-called cover type). It is customary to insert the earphone into the external auditory canal when using it. Therefore, because the external auditory canal is blocked, the external auditory canal is compressed, and the use of the ear can cause discomfort for a long time, and because it is not ventilated, it may cause sweating and feel uncomfortable, and it may cause loneliness due to isolation from the outside world, resulting in mental and physical body. The burden, and when the danger occurs, no alarm sounds, lack of security. When the latter earphone is used, it is not necessary to insert the external auditory canal, but it is in contact with the head or against the ear. Therefore, the external auditory canal is not pressed like the earphone of the former.

The outer peripheral portion of the cushion 7 is housed inside, and it is preferable to weld the joint portion of the bobbin half 4' integrally by ultrasonic welding, and the bobbin 4 is formed as shown in the uppermost portion of the drawing. As described above, the bobbin 4 has a two-divided structure in which the coil frame 4 is divided into a lateral direction, whereby the cushion member 7 and the like are easily accommodated therein, and the assembling property is excellent. Further, the bobbin 4 shown in the drawing has a structure in which the right and left sides are divided, but may be a vertical divided structure in which the upper and lower sides are divided into two. Further, the magnet 5 may be loaded in the final process or may be loaded at any stage. Further, the magnet supporting portion 6 may not be in the above-described cylindrical shape, and may be formed in a disk shape or another shape. As shown in Fig. 3, the coil 8 is wound around the outer circumference of the main body portion of the bobbin 4, that is, the open-hole bone conduction device 3 as shown in Fig. 1(a) is completed. In Fig. 3, 8a and 8b are lead wires of the coil 8 for energizing the sound signal. As shown in Fig. 1(a), the bone conduction device 3 is placed in the hollow portion of the casing 1 by an insertion method or a filling method. At this time, the magnet 5 is located outside (in the flange portion 1b of the casing 1). The insertion method, as it is shown in the figure, is a method of fixing by inserting an adhesive with a central portion of the casing 1. The filling method is also shown in Fig. 4 as an illustration of the assembled open-hole bone conduction earphone 3A from the side. There is an extremely small difference in height between the outer peripheral surface of the flange portion 1b and the outer peripheral portion of the spacer 2, or there is no height difference.

As shown, it alternates along the direction of the currents ia, ib. The so-called right-spiral law of ampere is the law that indicates the relationship between the current and the magnetic field generated around it, which means that when the current flows, the direction of the current is taken as the right spiral. In the direction, a magnetic field is generated along the spiral direction of the right helix. In the figure, 4 is a bobbin, 6 is a device, and 7 is a buffer. The moving member 6 of this example is a structure in which a magnet 5 is provided at one end. Magnetic body.

The vibration transmission, the coil bobbin 4 it is transmitted to the bone from the (four) member by covering the vibrating body and transmitted to the auditory nerve. At this time, it is important to cover the vibrating body. The member should have a hardness with the external auditory canal, and can be used to fill the periphery (4). As for the holding buffer 7, if the balance of the movable member 6 is recorded, it may be used. In addition, in order to make the moving member vibrate quickly, the cushioning material 7 is preferably lower in hardness. It consists of a magnet 5 moving member 6, a buffer 7, a bobbin 4, and a coil 8. The bone conduction device 3 functioning as a vibrating body is disposed in the casing i, and the vibration is transmitted to the casing 1. The air sound is a sound that propagates as vibration in the air and vibrates the tympanic membrane and transmits it to the quilt. The hearing device called the cochlear Ί*. In contrast, the vibration of the bone conduction device 3 of the present invention is directly transmitted from the auricle G to the cochlea F in Fig. 5, and then the auditory nerve is recognized as a sound by the brain.
