Abstract

A microphone (40) of a headset device is provided with a sensor support member (46) for supporting a convex portion (46B) in a state separated from a microphone housing (41) to transmit a vibration to a vibration sensor (47), wherein a plurality of circular members (46D1) with different diameters are formed at a support unit (46D) of the sensor support member (46). The sensor support member (46) is made of an elastic material. Thus, the convex portion (46B) (the vibration sensor) is in a floating state against the microphone housing (41). Even in the case where a sliding vibration between an ear hook and an ear and the like are generated on the ear hook side, the support unit (46D) (each circular groove (46D1)) of the sensor support member (46) absorbs the vibration, so that the transmission of a vibration from the outside to the vibration sensor (47) is restricted.

Is done. When the headset device 10 is worn on the ear, the convex portion 46B of the microphone 40 is positioned on the milky protrusion (C portion in FIG. 6) of the user's temporal region (temporal bone). In addition, since the V-shaped spring 60 is in a state where both ends are contracted compared to the natural state when the headset device 10 is worn on the ear, a restoring force that is elastic toward the outside is generated. However, it occurs in a direction to widen the space between the ear hook 20 and the microphone 40.

<Wearing state of headset device>
Next, a state when the headset device 10 is worn on the ear will be described.
FIG. 5 is a diagram showing a state where the headset device 10 is worn on the ear, and FIG. 6 is a diagram showing a state where the headset device 10 is worn on the ear.
Here, FIG. 6 shows an ear part necessary for the description. An ear ring M1 in which the upper side of the ear forms an outline of the ear, an ear lobe M2 in which the lower side of the ear forms a lower profile, a ring ring M3 between the ear ring M1 and the ear lobe M2, a hole extending to the eardrum is an outer ear canal M4, and The inner side of the ear ring M1 is the opposite ring M5.

When the headset device 10 is worn, the ear hook 20 is spread in a direction (arrow B in FIG. 1) away from the earphone 50 side from the first contact portion 23, the earphone 50 is inserted into the external ear canal M4, and a hooking portion. 22 is hung between the ear ring M1 and the temporal region. The first contact portion 23 is routed from the ear ring M1 so as to be along the back side of the opposite wheel M5, the microphone 40 is directed to the milky projection portion (C portion in FIG. 7) on the temporal region, and further the second contact portion. The part 24 is brought into contact with the back side of the earlobe M2 or the ear ring tail M3.

At this time, since both ends (the main portion 21A and the sub portion 21B) of the ear hook 20 are attached to the ear in an expanded state, a force is generated in the shrinking direction and the first contact portion 23 is pushed to the back side of the ear ring M1. Hit it. Furthermore, since both ends of the V-shaped spring 60 are contracted from the natural state, a restoring force is generated toward the outside (that is, in a direction in which the space between the ear hook 20 and the microphone 40 is widened). It will be. As a result, the other side surface of the ear hook 20 is pressed against the back side of the ear ring M1, and the convex portion 46B of the microphone 40 is pressed onto the milk projecting portion of the user, whereby the headset device 10 (ear hook 20 + V-shaped). The shaped spring 60 + the microphone 40) is sandwiched between the user's ear ring M1 and the temporal region.

<Action and effect>
<Headset device>
In the headset device 10 configured as described above, the hook portion 22 of the ear hook 20 is sandwiched between the ear ring M1 and the temporal region, and the ear hook 20 and the microphone 40 are connected by the V-shaped spring 60.

Positioning in the thickness direction of 10 is reliably performed.

Further, the shape of the ear hook 20 is changed to a latching portion 22 that is hung between the ear ring M1 and the temporal region, a first contact portion 23 that is addressed from the ear ring M1 along the back side of the opposite wheel M5, and the earlobe M2 or Since the second abutment portion 24 that hits the back side of the ear ring tail M3 is provided, it can be securely attached to the user's ear at three contact points.

Further, by forming the inner member 21D that forms the latching portion 22 of the ear hook 20 from an elastic material, both ends (the main portion 21A and the sub portion 21B) of the ear hook 20 with the headset device 10 attached to the ear. ) Force is generated in the direction of contraction. Since the earphone 50 on one end side of the ear hook 20 is inserted into the ear canal M4, the first contact portion 23 which is the free end side is further from the ear ring M1 to the back side of the opposite wheel M5 and further to the second contact portion. 24 is pressed against the back side of the earlobe M2 or the ear ring tail M3 by the force with which the ear hook 20 contracts. Thereby, the headset device 10 is reliably positioned on the surface extending in the X-axis and Y-axis directions with respect to the ear.

As described above, the headset device 10 according to the present embodiment can reliably perform the positioning in the three-axis directions while being worn on the ear, and can improve the fit compared to the conventional one.

Can improve the reliability.

Also, the headset device 10 according to the present embodiment can acquire a whispering sound or the like of the user by the microphone 40 because the microphone 40 is located on the milk projecting portion located on the back side of the ear. Further, compared to the case where the sound uttered from the mouth is detected by air vibration as in the case of the conventional microphone, it is possible to detect only the sound without detecting external noise or the like. This eliminates the need for a circuit configuration such as a noise canceller. As a result, it can be used even in noisy environments such as pachinko halls, etc., and it is not necessary to use a circuit configuration such as a noise canceller. Is possible.

Furthermore, since the headset device 10 is securely attached to the user's ear as described above, it is possible to reduce the feeling of pressure and numbness compared to the conventional device, and to improve the fit that the user feels. It becomes.

The support portion 46D of the sensor support member 46 has a diameter on the support portion 46D. A plurality of annular portions 46D1 having different dimensions are formed. The sensor support member 46 is made of an elastic material. For this reason, the convex portion 46 B is in a floating state with respect to the microphone casing 41.
On the other hand, in the state where the headset device 10 is worn on the user's ear, as described above, the convex portion 46B of the microphone 40 is pressed against the user's milk projection by the restoring force of the V-shaped spring 60. Thus, the headset device 10 (ear hook 20 + V-shaped spring 60 + microphone 40) is sandwiched between the user's ear ring M1 and the temporal region. At this time, the convex portion 46B is pushed into the microphone casing 41. Even in this state, the convex portion 46B (vibration sensor 47) is lifted from the microphone casing 41 by the support portion 46D of the sensor support member 46. It will be supported in the state.
Further, even when the convex portion 46B moves on the XY plane with respect to the microphone casing 41 (that is, when the convex portion 46B moves to the left and right in FIG. 3), the annular groove 46D1 is deformed. The convex portion 46B is supported in a state where it floats from the microphone casing 41.
