Problems solved by technology

[0010] However, in the latter earphones, the earphones are arranged at both ends of the hanger part of the earphone headband made of elastic members, and the earphone headband is worn on the head for use, so the number of parts is large, the assembly is complicated, and the cost is also high. Amplitude increase
Since the wearing device is large and heavy, physical strength is required, and the head is oppressed when wearing it, causing a heavy feeling, and it is easy to get tired if worn for a long time
When it is not in use, it needs a storage place, etc. There are many problems

Embodiment 1

[0061] figure 1 (a) is a longitudinal sectional view of the perforated bone conduction earphone according to the first embodiment of the present invention.

[0062] 1 in the figure is, for example, a housing made of elastic members such as silicone rubber and synthetic rubber. The outer periphery of the outer end portion is constituted by a substantially disc-shaped flange portion 1b having a constant thickness. In use, the cylindrical portion 1a is inserted into the external auditory canal, and the flange portion 1b is similarly inserted into the external auditory canal. As the material of the casing, a material and a hardness with good vibration transmission efficiency are selected.

[0063] Covering the outer circumference of the cylindrical part 1a figure 1 The substantially cylindrical spacer 2 shown in (b). The cushion 2 is made of a soft elastic member. Since the shape of the external auditory canal varies from person to person, when the bone conduction earphone is ...

Embodiment 2

[0084] Figure 10 It is a sectional view of the second embodiment of the present invention. The present embodiment is characterized in that the overall outer shape is made into a substantially cylindrical shape slightly elongated in the axial direction. Figure 11 (a) is an appearance explanatory drawing, (b) is a front view.

[0085] In this embodiment, the shape of the movable member 6 is simple. That is, it is characterized in that the movable member 6 is made into an elongated cylindrical shape, and a ring-shaped magnet 5 is installed on the outer periphery of one end portion (corresponding to the outer side of the external auditory canal after being inserted into the external auditory canal), forming a perforated bone conduction transmission. piece 3. In this example, one end portion of the movable member 6 functions as a support portion for the magnet 5 .

Embodiment 3

[0087] Figure 12 Another example of the bone conduction device 3 is shown. In this 3rd embodiment, magnet 5 is housed at the end portion of movable member 6, and buffer 7 and groove 6a are made one, and the axial dimension of movable member 6 and bobbin 4 is relatively short, besides, basically The structure is substantially the same as that of the bone conduction device 3 described above, so the description is omitted.

[0088] Figure 13 is a sectional view showing an assembled state.

[0089] Figure 14 (a) is an explanatory diagram of a completed state, and (b) is a front view.

Abstract

The present invention relates to a boring type bone conduction earphone, provided with a magnetic body with the axial portion provided with a through hole (6') communicated with the outside when wore on ears, at least more than one buffer object (7) arranged at the periphery of the magnetic body, a coil frame (4) arranged at the periphery of the magnetic body, used for containing the buffer object in a main body and wound by a coil (8) outside the main body, and the boring type bone conduction member formed through the magnetic body with the through hole (6'). The earphone in the present invention does not need an earphone head ring, is provided with an external auditory canal inserted miniaturized simple structure, can be communicated with the outside, is provided with a vent ability and has no pressing feel when wore on ears. The earphone can be used underwater or on land.

Description

technical field [0001] The invention relates to a small open hole bone conduction earphone which is comfortable to wear and easy to use. Background technique [0002] Earphones are generally roughly divided into conventional earphones that are inserted into the external auditory canal to plug the ears, bone conduction earphones that also plug the ears, and bone conduction earphones that can be used without being inserted into the external auditory canal. [0003] The former earphones include, for example, Document 1 (magnetic earphone) and Document 2 (piezoelectric). [0004] The latter's earphones then have such as document 3 (so-called outer bowl type). [0005] The former traditional earphones are inserted into the external auditory canal during use. Therefore, due to the blockage of the external auditory canal, the external auditory canal will be oppressed, and it will cause discomfort when used for a long time. burden, and when danger occurs, the siren cannot be hear...
