2. Description of the Related Art In recent years, there has been provided a display device called a head mounted display in which a display device using a liquid crystal display or the like is incorporated in an eyeglass-type frame. Since a display device of this kind can only view an image by an individual, it is desirable to listen to sound individually. Therefore, it has been considered to configure a glasses-type earphone device by attaching the earphone body to a glasses-type frame.

[0003] By the way, since a cable is connected to the earphone body, the cable hangs down when the earphone body is not used, and it is unsightly. Also, the cable may be entangled with other members. It is desirable to keep it fixed.

Therefore, for example, as shown in FIG. 9, a locking projection 11 protruding from the outer surface of the temple 3 provided on the frame 1 and a clip piece 12 extending to the rear end of the temple 3 and protruding rearward are provided. Have been proposed. In this configuration, the earphone main body is detachably held on the frame 1 by sandwiching the earphone main body between the locking projection 11 and the clip piece 12.

[0005]

However, in the above-described configuration, the clip piece 12 is projected rearward to hold the earphone body to the frame 1, so that the backrest 21a is like a so-called high-back chair.
When wearing an eyeglass-type earphone device when sitting on a chair such as a chair on which the head H is placed on the upper part or a reclining chair having a head rest on the upper part of the backrest, the clip piece 12 hits the chair and the frame 1 is moved. The frame 1 is pushed forward and the position of the frame 1 is shifted. In particular, when applied to a head-mounted display for the purpose of displaying a stereoscopic image, if the position of the frame 1 shifts, the distance between the built-in display device and the eyes changes.
In some cases, stereoscopic vision may not be possible.

Recently, in a massage machine, this kind of glasses-type earphone device is sometimes used in order to enhance the effect of relaxation or the effect of refreshing from a relaxed state to an awake state. When used for the purpose, it is necessary to know the physiological condition of the user. Therefore, in order to extract physiological information, a clip-shaped pulse sensor (a transmission-type sensor in which a light-emitting element and a light-receiving element are arranged facing each other) is attached to the earlobe, or a pulse sensor (a light-emitting element and a light-receiving element is attached to the forehead). (Reflection type sensors arranged side by side in the same direction).
No. 127677).

However, a sensor worn on the ear lobe often gives the user a sense of incongruity, and a sensor worn on the forehead requires a wearing band, so that the work of wearing on the head is troublesome. Have.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the invention according to claim 1 is to provide a spectacles type in which the position of a frame is not shifted even when the back of the head is placed on a back of a chair or the like.

The feature of the present invention lies in a structure in which the earphone body 4 is held on the frame 1 when not in use. Specifically, as shown in FIG. And a hook holding body 7b is protrudingly provided on the outer surface of the temple 3 behind the sheath holding body 7a to form a rest portion 7. The rest portion 7 is further pulled out from the earphone main body 4 as shown in FIG. A part of the cable 8 is formed with a curl cord portion 8 a to urge the earphone body 4 in a direction approaching the front 2 of the frame 1. The earphone body 4 has a conventionally well-known shape, is provided with an ear speaker part 4a formed in a round shape, and a part of the ear speaker part is inserted into the ear. The sheath portion 4b for accommodating a part of the cable 8 is extended along the shape. The sheath holder 7a includes a pair of protrusions 7c, and the sheath 4b is held between the two protrusions 7c. The sheath holding member 7a holds the sheath portion 4b along the temple 3. The hook holding member 7b is formed so as to project obliquely rearward with respect to the temple 3, and the distal end of the hook holding member 7b has a sheath portion 4b.
Is formed to have a recess 7d in which a part of the recess is fitted. A coupling portion between the ear speaker unit 4a and the sheath unit 4b in the earphone body 4 is engaged between the tip of the hook holder 7b and the temple 3, thereby urging the earphone body 4 toward the frame 1. Thus, the earphone body 4 can be held by the temple 3 against the tension acting on the cable 8.

According to the above-described configuration, the earphone main body 4 is fitted only by fitting the sheath portion 4b between the pair of projections 7c as the sheath holding member 7a and locking the ear speaker portion 4a to the hook holding member 7b. Since the earphone body 4 can be held by the temple 3, the work of fixing the earphone body 4 to the temple 3 is easy. Further, if the earphone body 4 is pulled backward along the temple 3, the earphone body 4 can be removed from the temple 3, so that it is easy to remove the earphone body 4 from the temple 3 and use it as shown in FIG.

The earphone body 4 is urged forward by the cable 8 and the forward movement of the earphone body 4 is locked by the hook holding member 7b instead of holding the ear speaker portion 4a of the earphone portion 4a from the front and back by the temple 3. Because of the structure, it is not necessary to provide the temple 3 with a portion projecting to the rear side of the earphone body 4. That is, as shown in FIG.
Since the temple 3 does not have a portion protruding rearward from the back of the head when it is attached to the backrest 21a,
In addition, the temple 3 does not contact the backrest 21a or the headrest 21c when the head H is in contact with the headrest 21c, and the frame 1 is not displaced with respect to the head H.

As described above, the massage machine requires the detecting unit 24 for detecting physiological information. In the present embodiment, a device for detecting the body temperature of the user is used as the detecting unit 24. I have. That is, it is known that the body temperature can be used to determine whether or not the user is in the sleep state. For example, the following relationship exists between the body temperature and the sleep state. High core body temperature results in increased arousal and reduced sleep quality. Decreased core body temperature during sleep is important in maintaining sleep quality. A decrease in body temperature during sleep and an increase during awakening ensure efficient activity and adequate rest.

However, if the detection unit 24 is separately mounted, the mounting is troublesome and a sense of incongruity may occur during the mounting. Therefore, the detection unit 24 is incorporated in the ear speaker unit 4a. Here, the ear speaker section 4a of the earphone body 4 generally has a structure as shown in FIG. The ear speaker unit 4a includes a columnar permanent magnet 31 fixed in a housing 30 partially inserted into the ear.

This ear speaker section 4a has basically the same configuration as the ear speaker section 4a having the configuration shown in FIG. 6, except that the housing 30 further includes a thermopile 34 and a thermistor 35.
And built-in. The thermopile 34 and the thermistor 35 are arranged on the opposite side of the permanent magnet 31 from the diaphragm 33. A guide hole 36 is formed in the housing 30 so that infrared rays radiated from the eardrum can be guided to the thermopile 34. That is,
Openings are formed in the permanent magnet 31 and the diaphragm 33 at positions corresponding to the guide holes 36. Further, the portion of the housing 30 to be inserted into the ear is formed such that the central portion protrudes more toward the inside of the ear than the peripheral portion, so that infrared rays from the eardrum can be easily introduced into the guide holes 36. The thermistor 35 is provided for measuring the temperature of the thermopile 34.

Thermopile 34 and thermistor 35
Is provided to measure the body temperature of the user by measuring the amount of infrared radiation radiated from the eardrum. Now, assuming that energy radiated from the eardrum having a temperature of T (K) enters the thermopile 34 having a temperature of TE (K) through the guide hole 36, σ (T ⁴ −TE ⁴ ) is obtained from the thermopile 34. It is known to output a voltage proportional to. Here, σ is the Stefan-Boltzmann constant.

When the temperature TE of the thermopile 34 is detected by the thermistor 35 and used together with the output voltage of the thermopile 34, the temperature of the eardrum can be detected. That is, as shown in FIG. 8, the output voltage of the thermopile 34 and the voltage detected using the thermistor 35 are amplified by the amplifiers 37a and 37b, respectively.
Further, they are converted into digital values by A / D converters 38a and 38b, respectively. The output of the thermopile 34 and the output of the thermistor 35 obtained as described above are given to the arithmetic unit 39 composed of a microcomputer, and the arithmetic operation based on the above equation is performed to detect the temperature of the eardrum. That is, the body temperature of the user can be detected in a non-contact manner by the temperature detecting element built in the ear speaker unit 4a.
