  Referring to FIG. 1, an electronic device 100 includes an ear wearing device 1 and a mobile terminal device 3. The ear wearing device 1 and the portable terminal device 3 are connected by a cord 2. The ear wearing device 1 includes an electrooculogram measuring device for right ear 1R and an electrooculogram measuring device for left ear 1L. The ear wearing device 1 may be configured to include either one of the right ear electrooculogram measuring device 1R and the left ear electrooculogram measuring device 1L. The right-eye electrooculogram measuring device 1R includes a measurement electrode 1R4 for measuring an electrooculogram, a speaker unit 1R21, and a reference electrode 1R5. The specific configuration of the right ear electrooculogram measuring device 1R will be described in detail later. Similarly, the left ear electrooculogram measuring device 1L includes a measurement electrode 1L4, a speaker unit 1L21, and a reference electrode 1L5 for measuring electrooculogram. The right ear electrooculogram measuring device 1R and the left ear electrooculogram measuring device 1L each correspond to an electrooculogram measuring device.

  Referring to FIGS. 2A to 2C, the right ear electrooculogram measuring device 1 </ b> R includes a first support 1 </ b> R <b> 1 and a second support 1 </ b> R <b> 2. The first support portion 1R1 and the second support portion 1R2 in this embodiment are both made of silicon, but a conventionally known material such as a plastic resin may be used. The first support portion 1R1 is formed in a thin plate shape. The first support portion 1R1 and the second support portion 1R2 are connected to each other at one end and the other end. The right ear electrooculogram measuring device 1R is worn by the user such that one end and the other end where the first support portion 1R1 and the second support portion 1R2 are connected are the upper end portion and the lower end portion, respectively. Is done. Between the first support part 1R1 and the second support part 1R2, a tragus insertion part 1R3 serving as a clamping part that clamps a part of the user's ear is formed. That is, the right-eye electro-oculography measuring device 1R of the present embodiment selects the tragus 50d as a part of the user's ear to be sandwiched, and the tragus 50d is formed by the first support portion 1R1 and the second support portion 1R2. It is designed to be pinched.

  The name of each part of the user's right ear 50R is as shown in FIG. That is, the right ear 50R includes an auricle 50R1, an auricle 50a, a counter wheel 50b, an external auditory canal hole 50c, a tragus 50d, a tragus 50e, and an earlobe 50f. Here, the tragus 50d is a protruding portion formed immediately before the ear canal hole 50c. Such a protruding portion can be sandwiched between the first support portion 1R1 and the second support portion 1R2. The tragus 50d itself has elasticity, and contributes to stable wearing when the right-eye electro-oculography measuring device 1R is worn on the right ear 50R. In the present embodiment, when mounting the right-eye electro-oculography measuring device 1R to the right ear 50R, the tragus 50d is inserted into the tragus insertion portion 1R3. The width of the tragus insertion part 1R3, that is, the interval between the first support part 1R1 and the second support part 1R2 is set to a width for sandwiching the user's tragus 50d. In the present embodiment, the first support portion 1R1 is provided with a first protrusion 1R11 that protrudes toward the second support portion 1R2. The second support portion 1R2 is provided with a second protrusion 1R23 that protrudes toward the first support portion 1R1. The first protrusion 1R11 and the second protrusion 1R23 contribute to stable wearing of the right ear electrooculogram measuring device 1R by narrowing the width of the tragus insertion part 1R3. In addition, although the 1st support part 1R1 and 2nd support part 1R2 of this embodiment are connected in series at each one end part and the other end part, 1st support part 1R1 and 2nd support part 1R2 are It is only necessary to be connected at at least one of the ends.

  Referring to FIG. 2A, the right-eye electrooculogram measurement device 1R includes a measurement electrode 1R4 that measures the electrooculogram of the user on the front side of the first support 1R1. Here, the front side is the side facing the user's skin when worn. Referring to FIG. 2C, the right ear electrooculogram measuring device 1R includes a speaker unit 1R21 and an ear pad unit 1R22. The ear pad portion 1R22 is provided on the second support portion 1R2 via the speaker portion 1R21. Components for emitting sound are housed inside the speaker unit 1R21. As shown in FIG. 3B, when the right ear electro-oculography measuring device 1R is attached to the right ear 50R, the ear pad portion 1R22 is inserted into the ear canal hole 50c as shown in FIG. At this time, the speaker portion 1R21 located on the proximal end side of the ear pad portion 1R22 pushes the tragus 50d forward of the user's face 40 as shown by an arrow 5a in FIG. The first support portion 1R1 is also pushed toward the front of the face 40 as indicated by the arrow 5b. Thereby, 1st support part 1R1 is pushed to the center side of the face 40, as shown by the arrow 5c. Thereby, measurement electrode 1R4 provided in 1st support part 1R1 is press-contacted to a user's skin.

  In the present embodiment, the speaker unit 1R21 is provided, but other components may be incorporated in the speaker unit 1R21 according to the use of the electrooculogram measuring device. In addition, when the purpose is only to measure the electrooculogram, the components in the speaker unit 1R21 can be removed.

  Referring to FIG. 2A, the right-eye electrooculogram measuring device 1R includes a reference electrode 1R5 provided at a position lower than the measurement electrode 1R4 when being put on. The reference electrode 1R5 is provided at a portion where the first support portion 1R1 and the second support portion 1R2 merge at the lower end. The reference electrode 1R5 is a so-called ground electrode. The reference electrode 1R5 is provided on the front side of the right ear electrooculogram measuring device 1R in the same manner as the measurement electrode 1R4. The reference electrode 1R5 may be provided on either the first support portion 1R1 or the second support portion 1R2. The reference electrode 1R5 should be as far as possible from the measurement electrode 1R4, and the reference electrode 1R5 of this embodiment is arranged so as to be in contact with the earlobe 50f. The position of the reference electrode is not necessarily on the lower side of the measurement electrode, and may be arranged at another position. The reference electrode 1R5 is equipped to stably measure the electrooculogram and determines the reference for the potential difference. For this reason, the reference electrode 1R5 is not necessarily required to be in pressure contact with the user's skin when measuring the electrooculogram. That is, the reference electrode 1R5 is less important in the adhesion to the skin than the measurement electrode 1R4, and only needs to be able to contact the skin to some extent. Even when the first support portion 1R1 and the second support portion 1R2 are not joined at the lower end portion, the reference electrode 1R5 may be provided on either the first support portion 1R1 or the second support portion 1R2. That's fine.

  Note that the left ear electrooculogram measuring device 1L is similar to the right ear electrooculogram measuring device 1R. The first support 1L1, the first protrusion 1L11, the second support 1L2, the speaker 1L21, the ear pad 1L22, A second protrusion 1L23 is provided. A tragus insertion part 1L3 is formed between the first support part 1L1 and the second support part 1L2. The left ear electrooculogram measuring device 1L includes a measurement electrode 1L4 and a reference electrode 1L5. The left-eye electrooculogram measuring device 1L is different from the right-ear electrooculogram measuring device 1R only in the direction, and each component is common to the components of the right-ear electrooculogram measuring device 1R. Detailed description thereof will be omitted.

  Here, the electrooculogram measurement principle will be described with reference to FIGS. 5 (A) and 5 (B). As shown in FIG. 5A, it is known that the human eyeballs 45R and 45L are positively (+) charged on the cornea side and negatively (−) on the retina side. Therefore, for example, as shown in FIG. 5B, when the eyeballs 45R and 45L face to the right, on the face side, the right side has a positive potential (+) and the left side has a negative potential (−). Although not shown, when the eyeballs 45R and 45L face to the left, the left side becomes a positive potential (+) and the right side becomes a negative potential (−) on the face side. In this way, the electrooculogram around the eyeball changes as the eyeball moves, so the electrooculogram measuring apparatus captures the change in electrooculogram. The captured change in electrooculogram can be used as a signal. Conventionally, an EOG (Electrooculography) method is known for measuring the electrooculogram, and this can also be used in the present embodiment. The ocular potential is easier to detect as the measurement electrodes 1R4 and 1L5 are placed closer to the eyeball.

  In the present embodiment, this change in electrooculogram is detected using an inverting amplifier circuit 4 as shown in FIG. The inverting amplifier circuit 4 includes an operational amplifier 4a. The operational amplifier 4a includes a minus terminal 4a1 and a plus terminal 4a2. The inverting amplifier circuit 4 includes a first input terminal 4b, a second input terminal 4c, and an output terminal 4d. The first input terminal 4b of the inverting amplifier circuit 4 is connected to a measurement electrode 1L4 provided in the left ear electrooculogram measuring device 1L. A measurement electrode 1R4 provided in the right ear electrooculogram measuring device 1R is connected to the second input terminal 4c of the inverting amplifier circuit 4. A first resistor 4e is provided between the first input terminal 4b of the inverting amplifier circuit 4 and the negative terminal 4a1 of the operational amplifier 4a. One end of the second resistor 4f is connected between the first resistor 4e and the minus terminal 4a1. The other end side of the second resistor 4f is connected to the output terminal 4d side of the operational amplifier 4a. A ground 4g is provided between the second input terminal 4c of the inverting amplifier circuit 4 and the plus terminal 4a2 of the operational amplifier 4a. The ground 4g is connected to the reference electrode 1R5 of the right ear electrooculogram measuring device 1R and the reference electrode 1L5 of the left ear electrooculogram measuring device 1L.

  The inverting amplification circuit 4 is a circuit that amplifies the voltage difference between the measurement electrode 1R4 of the right-eye electro-oculography measuring device 1R and the measurement electrode 1L4 of the left-ear electro-oculogram measurement device 1L. For this reason, the output Vout of the inverting amplifier circuit 4 is inverted with respect to the input.

  The output when such an inverting amplifier circuit 4 is used will be described with reference to FIGS. 7 (A) and 7 (B). As shown in FIG. 7A, when the eyeballs 45R and 45L turn to the left, a positive (+) signal is input to the first input terminal 4b of the inverting amplifier circuit 4, and a negative value is input to the second input terminal 4c. The signal (−) is input. As a result, a minus (-) signal is output from the output terminal 4d. On the other hand, as shown in FIG. 7B, when the eyeballs 45R and 45L turn to the right, a minus (−) signal is input to the first input terminal 4b of the inverting amplifier circuit 4, and the second input terminal 4c. A plus (+) signal is input to. As a result, a positive (+) signal is output from the output terminal 4d. Thus, different signals can be output depending on the type of eye movement. Note that the inverting amplifier circuit 4 is an example of means for detecting changes in the electrooculogram, and other known means may be used to detect changes in the electrooculogram. Further, even when either one of the right ear electrooculogram measuring device 1R and the left ear electrooculogram measuring device 1L is attached, a change in potential can be captured by the measurement electrode 1R4 or the measurement electrode 1L4. Changes in electrooculogram can be measured.

  Here, an example of an output change of the electrooculogram accompanying the movement of the eyeball will be described with reference to FIG. First, when the eyeballs 45R and 45L face the front at the time t = t0, the output Vout of the electrooculogram shows zero. When the eyeballs 45R and 45L are turned to the left at time t = t1, the output Vout of the electrooculogram shows a negative value. Since the electrooculogram is an electrostatic potential, ideally, it should maintain a constant value if the eyeball is left facing, but it is actually affected by the leakage current in the device. Output potential gradually decreases as shown in FIG. Further, the peak value of the electrooculogram depends on how much the eyeball has moved, that is, how much the eyeball has turned to the side. For this reason, the peak value of the electrooculogram increases as the side is viewed.

  When the eyeballs 45R and 45L are turned to the right at time t = t2, the output Vout of the electrooculogram shows a positive value. When the eyeballs 45R and 45L are turned to the left at time t = t3, the output of the electrooculogram is output. Vout again indicates a negative value. When the eyeballs 45R and 45L are turned to the right at time t = t4, the output Vout of the electrooculogram shows a positive value. The mobile terminal device 3 can be controlled by using such an output Vout as a signal and combining these signals in various ways.

  The mobile terminal device 3 is a player that can emit music, voice, and the like. The user can listen to the sound through the speaker unit 1R21 and the speaker unit 1L21. The user can change the electrooculogram by moving the eyeball, and can operate the mobile terminal device 3 by the change of the electrooculogram. The mobile terminal device 3 includes a bus 3a. The bus 3a includes a CPU (Central Processing Unit) 3b, a display interface 3c, a touch panel interface 3d, a wireless communication interface 3e, and a wired communication interface 3f. In the present embodiment, the ear wearing device 1 and the mobile terminal device 3 are connected via the cord 2 connected to the wired communication interface 3f. However, the ear wearing device 1 and the mobile terminal device 3 are connected to each other via a wireless communication interface. You may connect via 3e. A RAM (Random Access Memory) 3g, a built-in storage 3h, and a storage medium 3i are connected to the bus 3a. The storage medium 3i stores an operation system, an application program, and a data file. The data file is, for example, a music file. The operation system and application program are executed by the CPU 3b. The CPU 3b, RAM 3g, and the like connected to the bus 3a function as a control unit by cooperating.

  By operating these, the mobile terminal device 3 performs operations such as selection of music pieces, start, stop, and fast forward of performance. When the user wants to operate the mobile terminal device 3 by eyeball movement, the user sets the mobile terminal device 3 to the electrooculogram input mode. Thereby, when making the portable terminal device 3 perform desired operation | movement, a signal can be emitted by moving an eyeball and the portable terminal device 3 can be operated. For example, in the application program, the eyeball operation of “seeing the right twice continuously” and the operation of the mobile terminal device 3 of “jump to the next song” are associated with each other. In this case, when the user performs the operation of viewing the right twice continuously, the inverting amplifier circuit 4 outputs plus (+) → minus (−) → plus (+) → minus (−). . When the portable terminal device 3 receives such a combination of signals, the portable terminal device 3 performs an operation of “jumping to the next song”. Thus, the user can operate the portable terminal device 3 without using a hand. Such an operation of the mobile terminal device 3 is convenient, for example, in a crowded train.

  According to the electrooculogram measuring device (the electrooculogram measuring device for the right ear 1R, the electrooculogram measuring device for the left ear 1L) and the electronic device 100 according to the present embodiment, the eye is located at a position close to the eyeballs 45R and 45L while downsizing the device. The measurement electrodes 1R4 and 1L4 for measuring the potential can be pressed. That is, the right-eye electrooculogram measuring device 1R is a so-called earphone type, and is therefore very small. The right ear electrooculogram measuring device 1R inserts the ear pad portion 1R22 and the speaker portion 1R21 into the ear canal hole 50c and sandwiches the tragus 50d with the tragus insertion portion 1R3. For this reason, the right-eye electrooculogram measuring device 1R is attached to the right ear 50R in a stable state. At this time, the measurement electrode 1R4 provided on the first support portion 1R1 is pressed against the skin in order to spread the ear pad portion 1R22 and the speaker portion 1R21 tragus 50d forward. In addition, the measurement electrode 1R4 provided in the first support portion 1R1 is located near the eyeball 45R as compared with, for example, a case where the measurement electrode is installed in a portion inserted into the ear canal hole. As a result, the sensitivity of the electrooculogram is high. This effect is common to the left ear electrooculogram measuring apparatus 1L.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS. 9A, 9B, and 10. FIG. FIG. 9A is a front view of the right ear electro-oculogram measuring apparatus of the second embodiment, and FIG. 9B is a rear view of the right ear electro-oculogram measuring apparatus of the second embodiment. FIG. 10 is an explanatory diagram showing a state in which the right-eye electro-oculogram measuring apparatus according to the second embodiment is attached to the right ear.

  The first difference between the right ear electro-oculogram measuring device 11R of the second embodiment and the right ear electro-oculogram measuring device 1R is that the speaker portion 11R11 and the ear pad portion 11R12 are connected to the first support portion 11R1. It is a point provided. In addition, the second difference is that the right ear electrooculogram measurement device 11R of the second embodiment replaces the tragus insertion part 1R3 provided in the right ear electrooculogram measurement device 1R of the first embodiment. It is a point provided with insertion part 11R3. The point that the measurement electrode 11R4 is provided on the first support portion 11R1 is the same as in the first embodiment.

  In the first embodiment, the first support portion 1R1 of the right-eye electro-oculography measuring device 1R in the wearing state passes through the front side of the tragus 50d, and the second support portion 1R2 passes over the ear canal hole 50c. On the other hand, in the second embodiment, the first support portion 11R1 of the right-eye electrooculogram measuring device 11R in the mounted state passes over the ear canal hole 50c, and the second support portion 11R2 passes through the rear side of the auricle 50R1. To do.

  The first support portion 11R1 and the second support portion 11R2 are connected at the upper end. And insertion part 11R21 provided in the lower end part of 2nd support part 11R2 is inserted in penetration hole 11R13 provided in the lower end part of 1st support part 11R1. The dimension of the auricle insertion part 11R3 can be adjusted by adjusting the degree of insertion of the insertion part 11R21 into the insertion hole 11R13. The reference electrode 11R5 is provided above the insertion hole 11R13 of the first support portion 11R1. The reference electrode 11R5 can be in contact with the earlobe 50f as in the first embodiment.

  When the right-eye electrooculogram measuring device 11R of the second embodiment is mounted, it can be mounted on the right ear 50R in a stable state by adjusting the dimensions of the pinna insertion part 11R3. In addition, when the right ear electrooculogram measuring device 11R is attached to the right ear 50R, the elastic auricle 50R1 attempts to return to the original position at the rear. As a result, the first support portion 11R1 is also pulled backward. As a result, the measurement electrode 11R4 provided on the first support portion 11R1 can be brought into close contact with the skin. The measurement electrode 11R4 is in close contact with the base of the tragus 50d. That is, the measurement electrode 11R4 can be in close contact with the front side of the ear canal hole 50c.

  As described above, also in the second embodiment, the same effects as in the first embodiment can be obtained. In addition, you may make it equip 2nd Embodiment with a tragus insertion part like 1st Embodiment.
