Description

  The present invention relates to an ear-mounted electronic device.

  2. Description of the Related Art Conventionally, there are electronic devices that measure biological information related to the blood flow of a human body such as a pulse and a heart rate. Such electronic device products have various shapes and sizes, and some of them are downsized to be portable and are integrated into other products.

  As an example, there is an electronic device in which a pulse sensor is incorporated in a wristwatch. The user abuts the abdominal surface of the finger end on the pulse sensor incorporated in the wristwatch, whereby the pulse is optically detected by the pulse sensor, and the pulse rate is displayed on the display unit of the wristwatch body.

  Such miniaturized electronic devices are often used during exercise such as jogging and walking. However, in a wristwatch-type electronic device, the measurement result is displayed on the display unit of the wristwatch. Therefore, in order to confirm the measurement result, the wristwatch worn on the wrist must be lifted up to the height of the line of sight. It was an obstacle.

Therefore, the following technology has been devised as an ear-mounted electronic device that informs the measurement result by voice. That is, it is composed of a belt and headphones on which an ECG (electrocardiogram) measurement electrode is arranged, and the headphone type that wraps the belt around a trunk such as the chest and abdomen and outputs the heart rate measured via the ECG measurement electrode from the headphones. It is an electronic device (see Patent Document 1).
US Pat. No. 5,314,389

  However, in the electronic device of Patent Document 1, the cable that connects the belt wound around the trunk to the headphones is suspended from the head to the trunk. For this reason, the cable floated during the exercise, which hindered the movement of the arm while running and hindered the exercise.

  In addition, since the headphone holds the posture at the time of wearing only by the elastic force with respect to the bending of the arm portion, it is easily displaced or detached with the movement of the user's body, especially the movement of the head. There was a thing.

  Further, in order to measure the heart rate, the belt has to be wound around the trunk, and the wearing operation and wearing feeling of the belt are troublesome.

The present invention has been made in view of the problems as described above. The object of the present invention is to reduce the troublesomeness of wearing, to obtain a stable wearing feeling, and to always accurately measure biological information. It is to realize an ear-mounted electronic device that can perform the above.

An urging mechanism (e.g., a torsion coil spring 102R in FIG. 4) that urges the arm portions in a direction in which the tip portions are brought close to each other;
A straight line passing through the left and right ear holes is used as an oscillating axis (for example, oscillating axis S1 in FIG. 1A) by the urging force of the urging mechanism transmitted to each speaker unit through the arm part. It is characterized by its attitude.

According to the first aspect of the present invention, the main body including the audio output unit and the measurement unit is held near the lower back of the head when worn. Thereby, since the posture at the time of wearing is stabilized in a state where it is in contact with the lower part of the back of the head due to the weight of the main body, swinging with respect to the movement of the head of the user is suppressed, and a stable wearing feeling can be obtained. Moreover, the detection part for detecting biometric information is latched by one of the left and right earlobe. Thereby, the user can measure biological information by an easy operation such as pinching the earlobe between the detection means. In addition, for example, during movement, the earlobe moves less than the main body of the body, such as the torso and arms, reducing the troublesomeness of wearing and enabling more accurate measurement of biological information at all times.

According to the second aspect of the present invention, it is possible to obtain the same effect as the first aspect of the invention, and the bottom surface of the substantially hemispherical speaker portion is used as the sound emission surface, and the sound emission. The arm portion supports the side portion of the speaker portion so that the surface is directed forward when worn. Therefore, for example, when the speaker unit is formed so as to be insertable into the ear canal, the speaker unit is formed in a substantially hemispherical shape, so that a certain resistance is generated between the speaker unit and the ear hole when the speaker unit is attached or detached. Therefore, a certain feeling of wearing and stability can be obtained simply by inserting the speaker portion into the ear canal.

  Further, since the sound emitting surface has a substantially hemispherical shape facing forward, the ear canal is completely closed from the outside, and the sound of the outside world is not blocked. Therefore, for example, when the user is used during jogging, the user can hear external sounds related to traffic even if sound is output from the speaker unit.

Thereby, since the posture at the time of wearing is stabilized in a state where it is in contact with the lower part of the back of the head due to the weight of the main body, swinging with respect to the movement of the head of the user is suppressed, and a stable wearing feeling can be obtained. Moreover, the detection part for detecting biometric information is latched by one of the left and right earlobe. Thereby, the user can measure biological information by an easy operation such as pinching the earlobe between the detection means. In addition, for example, during movement, the earlobe moves less than the main body of the body, such as the torso and arms, reducing the troublesomeness of wearing and enabling more accurate measurement of biological information at all times. Become.

According to the first aspect of the present invention, the urging force of the urging mechanism of the main body that urges the tip of each arm in the direction of approaching is transmitted to each speaker through the arm, and the speaker Is pressed toward the inside of the head when worn.

According to the third aspect of the present invention, an ear-mounted electronic device that measures walking or running pitch is realized.

  Hereinafter, an embodiment in which the ear-mounted electronic device of the present invention is applied to an ear-mounted pulse measuring device (hereinafter abbreviated as “ear-mounted device”) 1 will be described in detail with reference to FIGS. Explained. The direction in the description is the direction for the user wearing the ear-worn device 1. Specifically, the face side (left side of FIG. 1 (b)) when the ear-mounted device 1 is worn is the front, the occipital side (right side of FIG. 1 (b)) is the rear, the left ear side is the left, The right ear is right, the top is up, and the bottom is down. In addition, the direction in which the left and right arm portions 3R and 3L are close to each other, that is, the direction toward the center of the head is defined as the inner direction, and the opposite is defined as the outer direction.

First, an outline of the ear-mounted device 1 will be described.
The ear-worn device 1 includes a main body unit 10, a right arm unit 3R, a left arm unit 3L, a right driver unit 34R and a left driver unit 34L that are speaker units, and a pulse sensor unit 5. . The right arm portion 3R is supported at the upper right end portion of the main body portion 10 so as to be urged in the direction of the inner arrow V1. The left arm portion 3L is supported at the upper left end portion of the main body portion 10 so as to be urged in the direction of the inner arrow V3.

  A right driver unit support portion 32R that supports the right driver unit 34R is provided at the tip of the right arm portion 3R. A left driver unit support portion 32L that supports the left driver unit 34L is provided at the tip of the left arm portion 3L.

  On the right side surface of the right driver unit support portion 32R, a pulse switch 36R for outputting a sound for reading out the pulse rate immediately after measurement is disposed. On the left side surface of the left driver unit support portion 32L, a radio is selected. A tuner switch 36L for performing the station is provided.

  The pulse sensor unit 5 is a detection means for detecting a blood flow state called a pulse, has a clip that can be clamped on the earlobe, which is a part of the auricle, and a sensor for optically detecting the pulse is sandwiched between the pulse sensor unit 5 and the sensor. It is arranged on the landing surface. The pulse sensor unit 5 is electrically connected through a cable 50 from the left side surface of the main body unit 10. Since the mechanism and configuration of the sensor for optically detecting the pulse are known techniques, detailed description thereof is omitted.

  In order to wear the ear-mounted device 1, the user grasps and spreads the right arm portion 3R and the left arm portion 3L in a direction in which the right driver unit 34R and the left driver unit 34L are separated from each other. Then, the ear-mounted device 1 is moved so as to wrap around the head from the back head H side, the right driver unit 34R is inserted into the right ear ear hole 7R, and the left driver unit 34L is inserted into the left ear ear hole 7L. The ear-mounted device 1 is worn.

  At this time, due to the urging force transmitted to the right driver unit 34R and the left driver unit 34L via the right arm portion 3R and the left arm portion 3L, the right driver unit 34R and the left driver unit 34L are directed in the ear canal. It is pressed (inward direction). Further, as shown in FIG. 1B, the back surface of the main body portion 10 (the back surface of the operation panel 16) is brought into contact with the lower portion of the occipital head H to maintain the posture of the main body portion 10.

With such an ear-mounted device 1, the following effects can be obtained.
First, the right driver unit 34R is inserted into the ear hole 7R (not shown) and the left driver unit 34L is inserted into the ear hole 7L, and the urging force transmitted through the right arm portion 3R and the left arm portion 3L is moved inwardly of the head. By being pressed, the right driver unit 34R and the left driver unit 34L are surely inserted into the ear canal. For this reason, it becomes difficult for each driver unit to come off with respect to the movement of the head, and a stable wearing feeling can be obtained.

  Further, a straight line connecting the right driver unit 34R inserted into the ear hole 7R and the left driver unit 34L inserted into the ear hole 7L can be the swing axis S1 on which the main body 10 swings in the vertical direction. The shift of the swing axis S1 of the device 1 in the axial direction is suppressed.

  Further, since the power source unit such as a battery and various control circuits are built in the main body unit 10, the main body unit 10 occupies most of the weight of the ear-worn device 1 and becomes a heavy object to some extent. For this reason, the main-body part 10 is contact | abutted by the lower vicinity of the back head H from the relationship between the dead weight and the rocking | fluctuation axis | shaft S1. Therefore, the ear-mounted device 1 is held in a stable posture in which the main body 10 is in contact with the vicinity of the lower part of the back of the head H, and even if the user is exercising, the swinging shaft S1 is swung in the rotational direction. The movement is suppressed.

  In addition, since there are three locations of the left and right ear holes 7R and 7L and the occipital head H, the abutment feeling that surrounds the head like conventional headphones is reduced, and a comfortable wearing feeling is achieved. Is obtained.

  The right arm 3R is pressed against the head from the outside of the auricle 11R (not shown), and the left arm 3L is pressed from the outside of the auricle 11L. Therefore, the right arm 3R does not hang on the base of the auricle 11R and the left arm 3L does not hang on the base of the auricle 11L, so that the glasses can be easily worn when the ear-mounted device 1 is worn.

  In addition, the pulse sensor unit 5 connected to the left side surface of the main body unit 10 is locked by sandwiching an earlobe 9L of the left auricle. Accordingly, since the ear-worn device 1 is completely worn by being worn on the user's head, the cable 50 is unlikely to obstruct the user's movement.

  Further, the pulse sensor 36R is disposed on the right driver unit support portion 32R (right side) while the pulse sensor portion 5 is sandwiched and locked on the left ear (left side). Thereby, the influence with respect to the pulse detection of the pulse sensor part 5 of the left side by operation with respect to the right side of the ear wearing type apparatus 1 called operation of the pulse switch 36R for hearing the measurement result of a pulse rate can be reduced.

Next, the structure of the ear-mounted device 1 will be described in detail.
The main body 10 incorporates various control circuits such as a radio reception circuit unit 114 and a pulse measurement unit 108, a power supply unit, and the like, and an operation panel 16 is disposed on the front surface. Further, a lid 14 that can be attached to and detached from the back surface, a right arm support portion 10R at the right end, and a left arm support portion 10L at the left end are formed.

  The operation panel 16 is provided with a display unit 12 and various switch groups 18 constituted by, for example, an LCD (Liquid Crystal Display). The various switch groups 18 include a mode switch 18 a for setting the operation mode of the ear-worn device 1, a radio switch 18 b for starting radio reception, the operation of the stopwatch, and the pulse of the pulse sensor unit 5. There are a start / stop switch 18c for starting or stopping the detection operation at the same time, a power switch 18d for turning on / off the power, and a volume switch 18e for changing the volume.

  The lid 14 is detachably attached to the main body 10 by a screw 14a. The lid 14 is removed, and the battery of the power supply unit is replaced.

  The right arm support portion 10R is a mechanism for supporting the right arm portion 3R, and the left arm support portion 10L is a mechanism for supporting the left arm portion 3L. Hereinafter, since the right arm support portion 10R and the left arm support portion 10L are symmetric mechanisms, the description of the left arm support portion 10L is omitted.

  The right arm support portion 10R includes an urging mechanism such as a torsion coil spring 102R for urging the right arm portion 3R in the arrow V1 direction (inward direction). As shown in FIG. 4, a torsion coil spring 102R is twisted at one end of the right arm 30R inserted from the upper end portion 104R of the right arm support portion 10R (this end portion is more preferably cylindrical in order to transmit the elastic force of the spring). Is wound, and the urging mechanism is configured to urge the right arm portion 3R in the direction of the arrow V3. By such an urging mechanism, the right arm portion 3R is urged in the direction of the arrow V3 and rotated about the rotation axis S5.

  The right arm portion 3R is configured by integrally forming a right arm 30R, a right connection portion 38R, and a right driver unit support portion 32R. As shown in FIG. 2A, the right arm 30R extends upward from the upper end of the right arm support portion 10R, and is then bent outward in a substantially semicircular shape diagonally upward to the right. Further, as shown in FIG. 3A, it is formed to be curved outward and rearward.

  The right connection portion 38R is formed in a cylindrical shape and mediates between the right arm 30R and the right driver unit support portion 32R. Specifically, the end portion of the right arm 30R is inserted and fixed in the cylinder of the right connection portion 38R, and the other end of the right connection portion 38R mediates by supporting the right driver unit support portion 32R downward. In addition, it is good also as a mechanism which adjusts the full length of the right arm part 3R by comprising so that expansion / contraction is possible, without fixing the right connection part 38R and the right arm 30R.

  The right driver unit support portion 32R is formed in a plate shape and supports the right driver unit 34R. Further, as shown in FIG. 3A, the right driver unit support portion 32R is formed in a substantially L shape so as to extend obliquely backward and downward.

  The right arm 30R constituting the right arm portion 3R, the right connection portion 38R, and the right driver unit support portion 32R follow the shape of the temporal region of the general human body from the ear canal 7R (not shown) to the back of the head H. A curved arm is formed. In addition, although each arm part demonstrated as having been formed in a curve, it is not restricted to this, It is good also as forming it by making it bend | curve linearly in upper surface substantially L shape.

  The right driver unit 34R is a speaker unit, is formed in a substantially hemispherical shape that can be inserted into the ear hole 7R, and a speaker 118 is disposed therein. A sound emitting surface 72 having a plurality of holes 70 for emitting sound is formed on the bottom surface forming the substantially hemispherical body. The right driver unit 34R is supported by the right driver unit support portion 32R on the substantially hemispherical side so that the sound emitting surface 72 is directed in the direction of the arrow V5 when mounted. A signal line from the main body unit 10 to the speaker 118 is disposed in the main body unit 10 from the right driver unit support unit 32R through the right connection unit 38R and the right arm 30R, and is electrically connected to the audio output unit 116. ing.

  Since the right driver unit 34R is formed in a substantially hemispherical shape as described above, a constant resistance is generated between the right driver unit 34R and the ear canal during attachment and detachment, and a constant feeling of wearing and stability can be obtained only by insertion into the ear hole. It has a shape. In addition, since the sound emitting surface 72 (bottom surface) has a substantially hemispherical shape facing forward, the ear canal is completely closed from the outside, and the external sound is not blocked. Therefore, for example, even when a sound is output from the speaker 118 while jogging, it is possible to hear the external sound related to traffic.

Next, the difference between the right arm portion 3R and the left arm portion 3L will be described.
A pulse switch 36R, which is an operation instruction button, is disposed on the right side surface of the right driver unit support portion 32R. Further, a tuner switch 36L is disposed on the left side surface of the left driver unit support portion 32L.

  A flange 34 formed in a plate shape is connected to the rear side end portion of the left connection portion 38L. The scissors 34 are for pinching and locking the pulse sensor unit 5 when the user does not use the pulse sensor unit 5.

  The pulse sensor unit 5 is electrically connected to the main body unit 10 from the left side surface of the main body unit 10 via the cable 50 and is configured to be communicable with the pulse measurement unit 108. The pulse sensor unit 5 includes a light-emitting element such as a light-emitting diode and a light-receiving element such as a photodiode inside, and includes a clip portion by a biasing mechanism such as a torsion coil spring so that the pulse sensor unit 5 can be clamped to the earlobe. Has been.

FIG. 5 is a block diagram showing the functional configuration of the ear-mounted device 1.
According to the figure, the ear-worn device 1 includes a CPU (Central Processing Unit) 100, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 104, a vibration measuring unit 106, and a pulse sensor unit 5. The pulse measurement unit 108 that measures the pulse rate from the pulse detected in Step 1, the input unit 110, the display unit 112, the radio reception circuit unit 114, the audio output unit 116 that outputs sound to the speaker 118, and the pulse switch 36R The tuner switch 36L is connected to the bus 120.

  The CPU 100 executes processing based on a predetermined program in response to a pressing signal input from the input unit 110, inputs instructions to each functional unit, inputs / outputs data, and causes the display unit 112 to display processing results. Or

  The ROM 102 stores an initial program for performing various initial settings, hardware inspections, loading of necessary programs, and the like, and a program for realizing the basic functions of the ear-worn device 1. The RAM 104 includes a memory area that temporarily stores various programs executed by the CPU 100 and data related to the execution of these programs.

  The vibration measuring unit 106 includes vibration detecting means such as an accelerometer, detects vibration of the ear-mounted device 1, measures a user's walking or running pitch from the detected vibration, and uses a speaker as a pitch sound. 118 to output. The pulse measuring unit 108 measures the pulse rate per unit time from the pulse detected by the pulse sensor unit 5 and outputs the measurement result to the speaker 118 with a predetermined sound.

  The input unit 110 corresponds to the above-described various switch group 18 and outputs a pressed signal of a pressed switch to the CPU 100. The display unit 112 displays various screens based on display control signals input from the CPU 100.

  The radio reception circuit unit 114 is a circuit unit that includes a reception antenna, receives a radio broadcast via the reception antenna, and causes the speaker 118 to output the received radio broadcast. The audio output unit 116 is a circuit unit that controls audio output to the speaker 118, and outputs audio from the speaker 118 by outputting an audio signal to the speaker 118. In the present embodiment, the pulse rate, pitch sound, and radio broadcast are selected and output from the speaker 118 by the user's operation.

  As described above, according to the present embodiment, the urging mechanism of the right arm support portion 10R causes the right arm portion 3R to face in the direction of the arrow V1, and the urging mechanism of the left arm support portion 10L causes the left arm portion 3L to face in the direction of the arrow V3. Is energized. The urging force by the urging mechanism is transmitted to the right driver unit 34R through the right arm portion 3R, and is transmitted to the left driver unit 34L through the left arm portion 3L. Then, each driver unit 34R, 34L is urged toward the center of the head, that is, in the direction in which each driver unit approaches, and is pressed into the ear canal. In addition to each driver unit 34R, 34L having a hemispherical shape, this inward pressing makes it difficult for the driver unit to come out of the ear canal and less likely to deviate from the movement of the user's head. Therefore, a stable wearing feeling can be obtained even during exercise.

  Further, the swing shaft S1 connecting the right driver unit 34R and the left driver unit 34L serves as the rotation shaft of the ear-worn device 1, but the main body 10 having a certain weight due to the incorporation of a battery or the like is Since it stabilizes in the state which contact | abutted under the back of the head H with dead weight, the attitude | position of the ear mounting | wearing type apparatus 1 is hold | maintained. Therefore, due to the weight of the main body 10, the swinging in the rotation direction around the swinging axis S <b> 1 due to the movement of the head is suppressed, and a stable wearing feeling can be obtained.

  In addition, since there are three contact surfaces on the head, that is, the right driver unit 34R, the left driver unit 34L, and the back surface of the main body unit 10, the auricle-sealed headphone and the headphone described in Patent Document 1 are used. Compared to this, the feeling of occlusion is reduced and a more comfortable wearing feeling is obtained.

  The right arm 3R is pressed against the head from the right side of the auricle 11R (not shown) and the left arm 3L is pressed from the outside of the auricle 11L. Accordingly, the right arm 3R does not hang on the base of the auricle 11R and the left arm 3L does not hang on the base of the auricle 11L, so that the glasses can be worn when the ear-mounted device 1 is mounted.

  Further, since the pulse sensor unit 5 is clamped and locked to the earlobe 9L of the left ear, only the head is involved in the mounting of the ear-mounted device 1. As a result, for example, the cable 50 does not get in the way when the user's arm is raised. Therefore, the troublesomeness of the cable being attached is reduced.

  In addition, since the pulse sensor unit 5 is connected to the left side surface of the main body unit 10, the user sandwiches the pulse sensor unit 5 on the left earlobe 9L. The pulse switch 36R for listening to the pulse rate of the pulse detected by the pulse sensor unit 5 is disposed on the right driver unit support 32R opposite to the earlobe 9L that sandwiches the pulse sensor unit 5. . Therefore, when the pulse switch 36R is pressed to hear the pulse rate, the pulse sensor unit 5 is not touched excessively, and adverse effects on pulse detection are reduced.

  In the present embodiment, the pulse switch 36R is provided on the right side of the ear-worn device 1 and the pulse sensor unit 5 is connected on the left side. However, the pulse switch 36R is provided on the left side and the pulse switch 36R is provided on the right side. It goes without saying that the same effect can be obtained even if the pulse sensor unit 5 is connected.

  Moreover, although it demonstrated as what forms what is called a vertical type driver unit in which the sound-emitting surface 72 faced the front surface, you may form as a sealed-type driver unit in which the sound-emitting surface faces the head inner side, or obstruction | occlusion It is good also as forming as an open air type driver unit of the grade which does not impair a feeling.

  In addition, the pulse rate is measured and output as sound. However, for example, the blood oxygen saturation concentration may be optically detected by a pulse sensor, and sound may be output. A typical thermometer may be built in, and the body temperature in the ear canal may be measured and output as audio.

  Moreover, although it demonstrated as supporting each arm part so that it might be urged | biased inside by the right arm support part 10R and the left arm support part 10L, it is not restricted to this, You may change a design suitably.

  For example, as shown in FIG. 6A, a substantially U-shaped headband is formed from a flexible and elastic material such as polypropylene, and the right driver unit 34R and the left driver unit 34L are provided at both ends thereof. It may be supported. When the headband 200 is bent and attached, an urging force (elastic force) toward the inner side of the headband 200 acts. For this reason, each driver unit can be pressed into the ear canal as in the present embodiment.

  Further, for example, as shown in FIG. 6B, hinge portions may be provided on both side surfaces of the main body portion 10, and an urging mechanism such as a torsion coil spring may be formed on the hinge portion. The right band 300 </ b> R and the left band 300 </ b> L may be configured to extend from the main body 10.
