[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wearable communication device such as a wearable transmission / reception device, and more particularly to a wearable communication device capable of making a call without being affected by external noise.

[0002] The present invention also relates to a wearable communication device capable of making a call without disturbing the surroundings and without being affected by external noise.

Further, the present invention relates to a wearable command input device, and more particularly, to a wearable command input device which can always input a command by a minute movement of a body while preventing erroneous input when bending or rotating a wrist. The present invention relates to a wearable command input device.

2. Description of the Related Art Most of conventional transmitting and receiving apparatuses such as portable telephones are of a type which is used by holding by hand. In this conventional transmitting and receiving apparatus, when the user wants to use it, he takes it out of his pocket or bag. Because of the necessity, there are problems such as “I cannot use it immediately when I want to use it” and “I cannot respond immediately when receiving a call”. For this reason, a wearable transmission / reception device that is worn on the body and used has attracted attention as a transmission / reception device that does not need to be taken out of a pocket or a bag, and can be used immediately when it is desired to use it.

US Pat. Nos. 5,381,387 and 5,499,292 disclose wrist-mounted handset units as wearable handset units to be worn on the body. In this wrist-mounted transmission / reception device, the boom-shaped speaker is extended to the inside of the palm of the hand when used, and the user talks in a posture in which his / her ears are covered.

As another wrist-worn type transmitting / receiving device, there is an all-in-one wristwatch-type PHS telephone which is worn on the wrist and operated in a style of watching a wristwatch.

[0007]

A wristwatch-type device which operates in the style of watching a wristwatch does not need to be taken out of a pocket or a bag at the time of use, so that it is excellent in immediate usability and responsiveness. However, since microphones and speakers are installed on the wrist, there are problems such as "the other party's voice is difficult to hear" and "this voice does not reach".

[0008] Further, in a conventional transmitting / receiving apparatus such as a portable telephone including a wrist-worn type wearing / receiving apparatus, the operator's voice tends to be loud when used, and together with the sound of the handset leaking to the surroundings, In a crowded street or the like, a problem of "disturbing the surroundings" has been pointed out.

Further, since the alarm sound upon receiving a call is loud,
In a crowded street or the like, a problem of "disturbing the surroundings" has been pointed out.

On the other hand, in a conventional wristwatch-type or earphone-type wearable transmission / reception device, the usage style is different from that of a traditional handset, so that "there is no appearance of a telephone call around, In addition, the operation buttons have become smaller with the miniaturization of the main body,
It has been pointed out that it is difficult to operate.

The aforementioned US Patents 5,381,387 and 549

In this wearable receiver, the shape of the distal end portion of the boom (BM) 58 is formed into a smooth downward convex dome shape as a whole, and a smooth groove is formed in the front-rear direction (fingertip-wrist direction). ing. FIG.

FIG. 22 is a view showing a fifth embodiment of the present invention. As shown in the figure, the actuator 72 is installed on the inner surface of the wrist. The amplifier unit is not shown in FIG. 22 because it is mounted on the back of the wrist in the same manner as in the embodiment shown in FIG.

As shown in FIG. 23, the tip of the vibrator 74 of the actuator 72 has a rod-like shape, and in order to improve the transmission efficiency of the received signal to the fingertip, the rod-like protrusion is used. It is attached so that it fits between flexors (Flexor digitorum, there are several) on the inner surface of the wrist. By adopting such a configuration, it is possible to maintain a good contact state between the vibrator and the flexor when worn, and it is difficult for the vibrator to come off the flexor even when the wrist moves. In addition, since the finger usually used for insertion into the ear is the second finger or the third finger, it is effective to dispose the vibrator in contact with the flexors corresponding to these fingers.

Further, as shown in FIG. 23, the rod-shaped vibrator 74 is adapted to the running direction of the flexor muscle (front and back: fingertip-wrist direction).
The contact state and comfort can be improved by increasing the cross-sectional shape of the front-rear direction. Since the running state of the flexors varies from person to person, in order to increase the transmission efficiency, the running state of the flexors is measured for each operator, and the shape of the tip of the vibrator is adjusted so that the engagement becomes good. It is effective.

The inside of the actuator 72 and the method of using the present embodiment are the same as those described above.

The fifth embodiment may have the configuration shown in FIG. This configuration takes a form in which the actuator 76 is installed on the inner side surface of the wrist, similarly to the form shown in FIG. The amplifier unit is not shown in FIG. 24 because it is mounted on the back of the wrist similarly to the embodiment shown in FIG.

As shown in FIG. 25, the shape of the vibrator 78 in the actuator 76 is a smooth downward convex dome shape as a whole, and its front-back direction (fingertip-
One or more smooth grooves are formed in the wrist direction).

In order to improve the transmission efficiency of the reception signal to the fingertip, a flexor (Flexor digitoru) on the inner surface of the wrist is provided in the groove.
m, there are several). By adopting such a configuration, it is possible to maintain a good contact state between the vibrator and the flexor when worn, and it is difficult for the vibrator to come off the flexor even when the wrist moves. In addition, since the finger usually used for insertion into the ear is the second finger or the third finger, it is effective to dispose the vibrator in contact with the flexors corresponding to these fingers.

Since the running state of the flexor muscles varies from person to person, in order to increase the transmission efficiency, the running state of the flexor muscles is measured for each operator, and the shape of the groove of the vibrator is adjusted so that the engagement becomes good. Adjusting is effective.

The inside of the actuator 76 and the method of using the present embodiment are the same as those described above.

In the embodiments shown in FIGS. 22 to 25, it is also possible to provide an operation switch interlocking contact mechanism as shown in FIG. 26 in the actuator portion. FIG.
As shown in FIG. 7, the mechanism is such that an actuator 82 provided with a SW knob 80 is spirally mounted on a cutout outer 86 (outer frame) serving as a guide 84 so that the SW knob 80 projects from the guide 84. Take the mounted configuration. FIG.
Fig. 7 shows the cross section. With such a mechanism, by the action of the guide 84 and the SW knob 80, the actuator (AC) 82 moves along the spirally cut guide,
It moves back and forth while rotating in the outer 86. FIG. 28 shows a state in which the vibrator 88 of the actuator 82 is extended, that is, a state in which the vibrator 88 is worn on a human body and used. FIG. 29 is a sectional view thereof.

By turning the SW knob protruding from the guide, the actuator moves back and forth and also operates as an operation switch of the apparatus.

As shown in FIG. 26, the wrist band 9
Reference numeral 0 is connected to the outer, and when used, the vibrator slides toward the wrist with respect to the outer, so that the vibrator is pressed against the skin surface, and the transmission efficiency of the reception signal is improved. When not in use, the tip of the vibrator is only slightly in contact with the skin surface, the contact pressure is weak, and the wearer of the wearer is less tired even after a long wearing.

FIGS. 27 to 29 show the protruding type vibrator in the fifth embodiment. However, such a mechanism is similarly provided in the uneven type vibrator in the fifth embodiment. Is possible.

Further, in the fifth embodiment,
An electric contact mechanism shown in FIG. 30 can be provided. This mechanism includes a wire 9 connected to an actuator (AC) 94 and a motor 96 along a wrist band 92.
8 is wound. In use, as shown in FIG. 31, the motor 96 winds the wire 98, and the wire 98 tightens the wrist band 92, whereby the actuator 94 is pressed against the skin surface, and the transmission efficiency is improved.

Further, as shown in FIG. 32, a contact mechanism using an air pump can be provided. As shown in the figure, this mechanism installs an air bag (102) on the lower surface of an amplifier unit (AU) 100, and
100 has an air pump 104 and a valve 106. As shown in FIG. 33, when used, the valve 106 is closed, and air is sent to the air bag 102 by the air pump 104, whereby the air bag 102 is inflated and the wrist band 108 is tightened. Pressed. Therefore, the transmission efficiency of the reception signal can be improved.

When not in use, the valve 106 is open and the air bag 102 is deflated, so that the wrist band 108
Is wrapped around the wrist without being tightened, the contact pressure of the actuator tip 112 on the wrist is weak, and fatigue is small even when worn for a long time.

In the fifth embodiment shown in FIGS. 22 and 23, the actuator 72 can be configured as shown in FIG. This actuator 72
Since the vibrator 74 is surrounded by the insulator 114, sound leakage to the surroundings can be prevented.
That is, as shown in FIG. 35, when the actuator 72 is pressed against the skin, the insulator 114 is in close contact with the skin so as to surround the contact portion 116 of the vibrator 74 with the skin, so that sound does not leak to the surroundings. In this configuration, the insulator 114 does not contact the vibrator 74.

As shown in FIG. 36, the insulator 114 may be provided in a donut shape on the lower surface of the actuator 72. FIG. 37 is a diagram showing a case where the skin comes into contact with the skin. With such a configuration, the insulator 114 comes into contact with the skin and the surface 118, so that the degree of adhesion to the skin is increased and the soundproofing effect is increased.

As shown in FIG. 38, from the viewpoint of soundproofing, it is also effective to make the inside of the actuator case 120 vacuum or nearly vacuum. That is, by gradually reducing the vibration component transmitted to the case 120, sound leakage to the surroundings is reduced. This configuration in which the inside of the actuator case 120 is made to be in a vacuum or a state close to a vacuum can take any shape of the vibrator.

According to the actuator having such a configuration, it is possible to clearly hear the reception sound without leakage of surrounding sounds. However, when the actuator moves away from the surface of the body, it is possible that a large amount of sound leakage occurs, or that the received sound changes significantly depending on how the actuator is pressed against the human body.

Therefore, as a sixth embodiment of the present invention, the receiving sound is stopped when the actuator is separated from the body surface, and the receiving sound is transmitted at a constant volume or sound quality regardless of how the actuator is pressed. FIG. 1 shows an actuator capable of preventing sound leakage to the surroundings.

FIG. 39 is a functional block diagram showing the configuration. Actuator (AC) 122 described so far
In addition, a pressure sensor (PS) for detecting the pressing force of the actuator, a receiving filter (FR) 126 for correcting a change in frequency characteristics, and a receiving filter table (conversion table) (FT) 128 are added. The function of the receiving filter table (conversion table) (FT) 128 will be described later. The pressure sensor (PS) 124 is provided in the actuator. Receive filter (FR) 1
26, the receiving filter table (FT) 128 is provided in the amplifier unit. Also, the receiving filter (FR)
The insertion position of 126 may be any position between the receiver (RX) and the actuator amplifier (AP) 132. Further, although this configuration diagram shows an example in which the actuator is brought into contact with the back of the palm, the present actuator can be applied to the other configurations described above. Next, the operation will be described.

The received voice signal R output from the receiver (RX) 130 is converted by a received filter (FR) 126
After correcting the change in frequency characteristics at the time of transmission by the back of the palm and the finger, the actuator amplifier (132) A
It is amplified by P and causes the actuator (AC) 122 to vibrate. The vibration of the actuator (AC) 122 is transmitted to the ear through the back of the palm and the fingers.

The pressing pressure from the pressure sensor (PS) 124 is input to the receiving filter (FR) 126. The receiving filter (FR) 126 has a pressure sensor (P
S) Based on the relationship between the received voice R and the input received voice R, the volume and sound quality (frequency characteristics) of the received voice R are changed with reference to the received filter table (conversion table) (FT) 128. A setting example of the reception filter table (FT) 128 will be described with reference to FIGS.

FIG. 40A shows the correction of the volume with respect to the pressing pressure. In the present embodiment, the more the actuator (AC) is pressed, the higher the transmission efficiency is, and thus the higher the volume heard by the operator. Conversely, when the pressing pressure is low, the sound volume is low. Therefore, when the pressing pressure is small, the volume heard by the operator can be maintained at a constant level by amplifying the volume. In FIG. 40A, when the pressing pressure is equal to or less than the threshold value THD, the amplification factor is set to zero. This is to prevent sound leakage to the surroundings. That is, almost no sound leakage to the surroundings occurs when the actuator (AC) is pressed against the skin, but a large sound leakage occurs as soon as the actuator (AC) moves away from the skin surface, Since such a property is annoying to the surroundings, by giving such characteristics, sound leakage to the surroundings is prevented.

Therefore, the fact that the actuator AC has separated from the skin surface is detected by using the pressure sensor (PS),
By suppressing the receiving sound volume, sound leakage can be reduced.

If only sound leakage is to be stopped, the signal to the actuator (AC) may be simply cut without using the receiving filter table (conversion table) (FT). In this case, further simplification is possible by using a simple switch mechanism instead of the pressure sensor (PS).

FIG. 40B shows the correction of the sound quality (frequency characteristic) with respect to the pressing pressure. In the present embodiment, as the actuator (AC) is pressed strongly, the transmission efficiency in the high frequency range increases. Conversely, if the pressing pressure is small, the transmission efficiency in the high frequency range is reduced, resulting in a muffled sound. Therefore, when the pressing force is small, by amplifying the treble range,
The sound quality heard by the operator can be kept constant.

The characteristics of the receiving filter table (FT) are set in advance, but can be adapted to each operator by performing calibration.

Although the receiving filter table (FT) is a separate block in FIG. 39, it can be provided in the receiving filter FR by software or hardware. In addition, Sho sensor (PS)
The installation position does not matter as long as the pressing pressure of the actuator (AC) can be measured, such as in the middle of the boom or at the base described in FIG. In any case, the pressure sensor (PS) only needs to be installed so as to measure the pressing pressure of the actuator (AC).

As described above, according to the present invention, the reception sound is stopped when the actuator is separated from the body surface, so that sound leakage to the surroundings can be prevented. Pressing force (pressure) of the actuator against the body surface
By changing the volume or sound quality of the received sound, the received sound is transmitted at a constant volume or sound quality regardless of how the actuator is pressed, so that sound leakage to the surroundings can be prevented.

Next, a seventh embodiment of the present invention will be described. The present embodiment is a wearable transmission / reception device that enables a user to make a call without disturbing the surroundings and without being affected by external noise.

FIG. 41 is a diagram showing a schematic configuration of a wearable transmission / reception device 134 according to the seventh embodiment. As shown in the drawing, the wearable transmission / reception device 134 includes a ring-shaped actuator 136 and an amplifier unit (AU) 138. The ring-shaped actuator 136 is mounted on the base of the finger, and the amplifier unit (AU) 138 is Attached to the back of the wrist by a wrist band.

FIG. 42 is a block diagram showing a schematic internal configuration of the wearable transmission / reception device 134. As shown in FIG. As shown in the figure,
The ring-shaped actuator 136 is an actuator (AC)
140 and a bone conduction microphone (hereinafter referred to as a bone conduction microphone) (TM) 142, and an amplifier unit (A).
U) 138 includes a microphone amplifier (MP) 144, an actuator amplifier (AP) 146, and an echo canceller (E).
C) 148, receiving filter (FR) 150, uttering filter (FS) 152, transmitter (TX) 154, receiver (R
X) 156, battery (BT) 158 for power supply
Is provided. A vibrator (VB) 160 is attached to the wrist band 162, and the ring-shaped actuator 136 and the amplifier unit 138 are connected to the cord 16
4. Although not shown in FIG. 42, a hook switch SW is provided in the amplifier unit.

When the wearable transmission / reception device 134 is used, a hook switch (SW) is operated and a line is connected. The hook switch (SW) can have various configurations, for example, the switch configuration shown in the third embodiment in FIG.

FIG. 43 is a functional block diagram showing the above configuration. The operation will be described with reference to FIG.

When the wearable transmission / reception device 134 is used, the fingertip of the finger on which the ring-shaped actuator (AC) 136 is mounted is inserted into the ear canal. In addition to the insertion of the finger into the ear hole, the entrance of the ear hole may be closed by a finger or a fingertip. Alternatively, the finger may be placed near the ear. The utterance voice S of the operator travels through the head and fingers,
The signal is input to a bone conduction microphone (TM) 142 and amplified by a microphone amplifier (MP) 144.

The received voice signal RE output from the receiver (RX) 156 is amplified by an actuator amplifier (AP) 146 after correcting a change in frequency characteristics at the time of transmission by a finger by a received filter (FR) 150. And
The actuator (AC) 140 is vibrated. The vibration (received voice R) of the actuator (AC) 140 is transmitted to the ear through the finger.

The bone conduction microphone (TM) 142 receives the received voice R at the same time as the voice S, but receives the received voice signal RE as a reference input.
C) 148 separates the uttered voice signal SE and the received voice signal RE.

The speech sound signal SE separated by the echo canceller (EC) 148 is converted into a speech filter (FS) 152
Thus, the transmission (TX) 154 transmits the signal after correcting the change in the frequency characteristic at the time of transmission by the finger.

The characteristics of the utterance filter (FS) 152 and the reception filter (FR) 150 are set in advance, but it is also possible to perform calibration and adapt to each operator.

The insertion position of the receiving filter (FR) 150 is determined by the receiver (RX) 156 and the actuator (A).
C) may be anywhere between 140 and
The insertion position of the utterance filter (FS) 152 is determined by the transmitter (T
X) Any position between the 154 and the bone conduction microphone (TM) 142.

When an incoming call is received, a vibrator (VB)
Although the operator is notified of this by vibrating 160, instead of providing vibrator (VB) 160,
By applying a large-amplitude signal to the actuator (AC) 140, it can be used instead of the vibrator (VB) 160.

In the seventh embodiment, the bone conduction microphone (TM) 142 is connected to the ring-shaped actuator 13.
6, the bone conduction microphone (TM) 142 may be placed on the operator's wrist, hand, finger, or toe.

Since the telephone call is made, it is possible to receive the sound without almost leaking the sound to the outside and without losing the clarity even under the noise.

Further, by inserting a finger, on which the ring-shaped actuator 136 is attached, into the ear canal, the uttered voice of the user is naturally fed back. As a result, even when the ambient noise is loud, the volume of human speech can be kept low, so that the influence of the speech on the surroundings can be suppressed.

Further, since the finger on which the ring-shaped actuator 136 is mounted is inserted into the ear hole of the ear to catch the utterance of the operator transmitted from the fingertip inserted into the ear hole, it is affected by external noise. Utterances can be captured stably without any need.

Further, since the vibrator is vibrated to notify the operator of the incoming call, only the operator can be notified of the incoming call without disturbing the surroundings.

FIG. 44 is a perspective view showing a schematic configuration of a wearable transmission / reception device according to the eighth embodiment of the present invention.

As shown in the figure, in the present embodiment, instead of the bone conduction microphone in the seventh embodiment,

Next, a call is made by inserting the fingertip of the finger on which the ring-shaped actuator 168 is mounted into the ear hole of the ear or the like.

The uttered voice S of the operator is the microphone (MC) 1
64 and amplified by a microphone amplifier (MP) 172. In addition, if you take a posture to insert the fingertip of the finger into the ear hole,
Since the mouth naturally approaches the microphone 164 installed on the inner surface of the wrist, the voice S of the operator can be recorded well.

The received voice signal RE output from the receiver (RX) 174 is amplified by an actuator amplifier (AP) 178 after correcting a change in frequency characteristics at the time of transmission by a finger by a received filter (FR) 176. And
The actuator (AC) 180 is vibrated. The vibration (received voice R) of the actuator (AC) 180 is transmitted to the ear through the finger.

The microphone (MC) 164 receives the received voice R at the same time as the voice S, but the echo canceller (EC) 1 receives the accepted voice signal RE as a reference input.
At 82, the uttered voice signal SE and the received voice signal RE are separated.

The speech sound signal SE separated by the echo canceller (EC) 182 is transmitted by the transmitter (TX) 186 via the speech filter (FS). Speech filter (FS) 184 and receive filter (FR) 176

The microphone (M) installed on the inner surface of the wrist
If the C) 164 can record only the voice S of the operator, the echo canceller (EC) 182 can be omitted.

When an incoming call is received, a vibrator (VB)
When the operator 188 vibrates to notify the operator of this, instead of providing a vibrator (VB) 188,
By applying a large-amplitude signal to the actuator (AC) 180, it is possible to substitute the vibrator (VB) 188.

According to the present embodiment, a call is performed by inserting an arbitrary finger of the arm on which the ring-shaped actuator is mounted into the ear hole of the ear or the like, so that almost no sound is leaked to the outside. It is possible to receive a call without losing clarity even under noise.

In the posture where the fingertip of the finger is inserted into the ear hole, the inner surface of the wrist approaches the mouth, so that the utterance voice S of the operator can be recorded favorably. This is close to the conventional posture of "calling a telephone", so that the user can make a telephone call in a natural form when viewed from the surroundings.

Furthermore, since the vibrator is vibrated to notify the operator of the incoming call, only the operator can be notified of the incoming call without disturbing the surroundings. The above-mentioned wearable transmission / reception device can also have the configuration shown in FIG.

[0120] As shown in FIG.
There is a knob 192 on the surface of the main body of the unit 0, and by sliding this knob back and forth, the boom 196 extending from the main body 194 of the wearable transmission / reception device 190 expands and contracts. An actuator 198 is installed at the tip of the boom 196.
The main body 194 of the wearable transmission / reception device 190 is attached to a wrist by a wrist band 200, and a microphone 202 is installed on the inner surface of the wrist of the wrist band 200. The functional configuration is the same as the configuration shown in FIG. The boom 196 and the actuator 198 can of course have the forms shown in FIG.

When using the wearable transmission / reception device 190, the knob 192 is slid forward and the foom 196 is pulled out. The hook switch SW is operated in conjunction with the sliding of the knob 192, and a line is connected.

18 and amplified by a microphone amplifier (MP2) 216.

At the same time, the uttered voice S of the operator is
The finger is transmitted to the bone conduction microphone (TM) 210 and amplified by the bone conduction microphone amplifier (MP1) 214. Further, the speech sound signal SE1 collected by the bone conduction microphone (TM) 210
And the uttered voice signal S collected by the microphone (MC) 218
E2 is synthesized by the mixer (AD) 220. The mixing by the mixer (AD) 220 may be appropriately controlled according to the ambient noise in addition to the method using the fixed mixing ratio.

The received voice signal RE output from the receiver (RX) 222 is amplified by an actuator amplifier (AP) 226 after correcting a change in frequency characteristics at the time of transmission by a finger by a received filter (FR) 224. And
The actuator (AC) 208 is vibrated. The vibration (received voice R) of the actuator (AC) 208 is transmitted to the ear through the finger.

[0130] The bone conduction microphone (TM) 210 receives the received voice R at the same time as the voice S, but receives the received voice signal RE as a reference input.
C) By 226, the uttered voice signal SE and the received voice signal RE are separated.

The uttered voice signal SE separated by the echo canceller (EC) 226 is converted to an utterance filter (FS) 228.
Thus, a change in frequency characteristics during transmission by a finger is corrected, and then transmitted by the transmitter (TX) 230.

Although the characteristics of the utterance filter (FS) 228 and the reception filter (FR) 224 are set in advance,
It is also possible to calibrate and adapt to each operator. The insertion position of the reception filter (FR) 224 is determined by the receiver (RX) 222 and the actuator (A).
C) Any position between 208 and, similarly,
The insertion position of the utterance filter (FS) 228 is determined by the transmitter (T
X) 230 and any position between bone conduction microphone (TM) 210.

According to the present embodiment, in addition to the effects of the seventh and eighth embodiments, it is possible to more clearly capture the voice of the speaker.

The above configuration using a bone conduction microphone and a normal microphone can be the configuration shown in FIG. As shown in the figure, a telescopic boom 234 extends from the main body of the wearable transmission / reception device 232, and a pad 236 is provided at the tip of the boom 234. The main body 238 of the wearable transmission / reception device 232 is attached to a wrist by a wrist band 240, and a microphone 242 is installed on the inner surface of the wrist of the wrist band 240. In this example, the main body 2
38 includes a bone conduction microphone and an actuator. Further, a motor for sliding the boom 234 is built in the main body 238.

When the wearable transmission / reception device 232 is used, the switch (PSW) 244 provided on the surface of the main body 238 of the wearable transmission / reception device 232 is pressed, whereby the boom 234 is pulled out by the power of the motor. , The line is connected. The boom 234 is connected to the actuator and the bone conduction microphone inside the main body 238 of the wearable transmission / reception device 232 so that the vibration is transmitted to each other. The other internal configuration is the same as that shown in FIG.

In this example, the uttered voice S of the operator is transmitted to the bone conduction microphone through the head, fingers, palm back, pad 236, and boom 234. In addition, the vibration of the actuator (acceptance voice R) due to the received voice is transmitted to the boom 23

In an embodiment using a ring-shaped actuator such as the seventh embodiment, as shown in FIG. 52, it is possible to install a microphone 246 for collecting the uttered voice in the case 248 of the actuator. . FIG.
In the case shown in FIG. 2 and when the microphone is installed on the wrist belt, by surrounding the microphone with the insulator 250, it is possible to suppress the vibration due to the received voice transmitted from the case or the belt. Therefore, the uttered voice can be captured clearly. It is more effective to use an echo canceller together.

FIG. 53 is a diagram showing an embodiment of a bone conduction microphone integrated with an actuator. As shown in the figure, in the present actuator, an electrode (EP1) 254 is provided on a vibration plate 252, and an electrode 256 is provided on a case portion of the actuator at a small interval from the electrode 254.

With such a configuration, the bone conduction microphone can be integrated with the bone conduction actuator, which facilitates installation. Also, by using such a bone conduction microphone, it is possible to clearly capture the uttered voice even under noise.

FIG. 54 is a functional block diagram of the present actuator. In this embodiment, the amplifier (AP) 2
Reference numeral 62 is not included in the actuator but is installed in an amplifier unit or the like. The operation will be described with reference to FIG.

The vibrator 2 of the actuator (AC) 264
When 66 is brought into contact with the human body such as a wrist or a finger, and the fingertip is inserted into the ear hole and uttered, the vibration caused by the utterance causes the vibrator to vibrate, so that the capacitance between the electrodes (EP1) 254 and 2 slightly changes. I do. This capacitance change is detected by a capacitance detection unit (CD) 258.
And amplified by the microphone amplifier (MP) 260, it is possible to capture the uttered voice. The gap between the electrodes greatly changes due to the vibration of the bone conduction actuator 264 due to the received voice, and the level is much larger than the amount of change due to the voice. Therefore, in order to extract only the uttered voice from the capacitance change between the electrodes, an echo canceller (EC) 268 for removing the influence of the received voice signal is provided as shown in the figure.

In this embodiment, the condenser microphone system using electrodes is used, but a dynamic microphone system using a coil can be used.

FIG. 55 is a perspective view showing a schematic configuration of a wearable transmission / reception device according to the tenth embodiment of the present invention.

As shown in FIG.
The main body of the wrist is attached to the wrist by a wrist band 272, and a microphone 274 is installed on the inner side surface of the wrist of the wrist band.

294, and a voice synthesis unit (VG) 295. Also, a battery for power supply is built in. Next, the operation will be described.

When using the wearable transmission / reception device 270, a user talks by inserting a fingertip of an arbitrary finger of the arm on which the main body of the wearable transmission / reception device 270 is mounted into the ear hole of the ear.

The uttered voice S of the operator is the microphone (MC) 2
The signal is input to a microphone 74 and amplified by a microphone amplifier (MP) 276. In addition, if you take a posture to insert the fingertip of the finger into the ear hole,
Since the mouth naturally approaches the microphone installed on the inner surface of the wrist, the utterance voice S of the operator can be recorded favorably.

The reception voice signal RE output from the receiver (RX) 290 is corrected by the reception filter (FR) 284 for the change in frequency characteristics at the time of transmission by the back of the palm and the finger, and then the actuator amplifier (AP) ) 28
It is amplified by 0 and causes the actuator (AC) 278 to vibrate. The vibration (received voice R) of the actuator (AC) 278 is transmitted to the ear through the back of the palm and the finger.

The microphone (MC) 274 receives the received voice R at the same time as the voice S, but the echo canceller (EC) 2 receives the received voice signal RE as a reference input.
At 82, the uttered voice signal SE and the received voice signal RE are separated. The uttered voice signal SE separated by the echo canceller (EC) 282 is converted into an utterance filter (FS) 28

According to the present embodiment, it is possible to issue a command by voice recognition described below. At that time, the voice command collected by microphone (MC) 274 is transmitted to voice recognition as in the case of transmission. It is interpreted as a command by the unit (VR) 294. Examples of voice commands include off-hook, on-hook, speed dial, dial, volume control, and the like.

When there is an incoming call from outside, vibrator (V
B) The 292 vibrates to notify the incoming call. When an incoming command is issued by voice, the line is connected. Next, a fingertip of an arbitrary finger of the arm on which the main body of the wearable transmission / reception device 270 is mounted is inserted into an ear hole of the ear, and a conversation is performed.

At the time of issuing a voice command, the voice synthesizing unit (VG) 295 causes the wearable receiving / packing device 270 to operate.
Is fed back to the operator by voice or musical sound. In the present embodiment, in addition to the effects of the above-described embodiments, a voice command is performed in a state where an arbitrary finger of the arm on which the main body of the wearable transmission / reception device is mounted is inserted into the ear canal. In addition, since off-hook, on-hook, or telephone number input can be performed using voice feedback, the wearable transmission / reception device can be operated without pressing a button in any scene of daily life including walking. Therefore, deterioration in operability due to downsizing of the apparatus can be suppressed.

In the embodiment shown in FIG. 55, a command can be input by a slight movement of the finger. FIG. 57 shows a functional block diagram of the internal configuration in that case.

[0155] An arbitrary supporting object such as a desk or a knee is hit with a fingertip of an arbitrary finger of the arm to which the main body of the wearable transmission / reception device 270 is attached, or the fingertips are brought into contact with each other to respond to the keying operation. The impact is transmitted to the acceleration sensor (SN) 296 inside the wearable handset through the finger and the hand. This shock
After being amplified by the sensor amplifier (SA) 298, the sensor filter (SF) 300 separates and extracts only a characteristic frequency component (for example, a frequency of 80 to 100 Hz) generated when a finger is hit.

The output of the sensor filter (SF) 300 is
The threshold value is processed by the comparator (CP) 302, and a pulse train PS is output in response to a fingertip by a fingertip. This pulse train PS is transmitted to the command execution unit (CM) 304, which compares the generation timing with the command table (CT) 306 to determine the execution command CMD.

Examples of the execution command include off-hook / on-hook / short dial / dial / volume adjustment.

[0158] Finger tapping with a fingertip can be performed not only on the supporting object but also between fingertips.

The input method using the fingertip in the present embodiment is described in, for example, Japanese Patent Application Laid-Open No. H10-200610.
A system as described in the issue “Permanent type telephone device” is used. The details of the command generation will be described later.

When there is an incoming call from outside, vibrator (VB) 292 vibrates to notify the incoming call. And
When an incoming command is issued by fingering, the line is connected. Next, a fingertip of an arbitrary finger of the arm on which the main body of the wearable transmission / reception device 270 is mounted is inserted into an ear hole of the ear, and a conversation is performed. The uttered voice S of the operator is a microphone (M

The received voice signal RE output from the receiver (RX) 290 is corrected by a reception filter (FR) 284 for a change in frequency characteristics at the time of transmission by the back of the palm and the finger, and then the actuator amplifier (AP) 280
And vibrates the actuator (AC) 278. The vibration (received voice R) of the actuator (AC) 278 is transmitted to the ear through the back of the palm and the finger.

In the present embodiment, off-hook, on-hook, telephone number input, and the like can be performed by tapping a fingertip on an arbitrary supporting object or tapping between fingertips. Since the wearable transmission / reception device 270 can be operated without pressing a button in any scene including daily life, deterioration of operability due to downsizing of the device can be suppressed.

However, although there is such an effect, in the above-described configuration, when the wrist is bent or turned, the vibration generated from the wrist joint causes
Incorrect input may occur. In order to prevent erroneous input that occurs when bending or turning the wrist, it is sufficient to raise the detection threshold value when detecting finger input,
In that case, there is a possibility that the fingertip at the fingertip cannot be detected with a weak fingertip input. A wearable command input device that solves such a problem will be described below.

It is converted into a command CCM based on the information of 334 and output. The vibration generator (NM) 338 in FIG.

In this case, since the key can be pressed by using all the fingers of the arm on which the main body is mounted, the input can be performed more quickly than by a single finger.

In the configuration described so far with reference to FIGS. 59 and 60, the use of the finger-passing motion detection band-pass filter (BPF1) 322 avoids interference due to finger motion other than key-stroke by the fingertip. It is possible to capture only a keystroke by the fingertip of the arm on which the main unit (MU) is mounted.

However, in the case of only the configuration described above, the wrist W of the arm to which the main unit MU is attached is attached.
When R is bent or turned, an erroneous input may rarely occur. This is because the vibration generated from the joint when the wrist joint is bent or rotated is the pass band of the fingering motion detection bandpass filter (BPF1) 322.
This is because it contains frequency components of 0 to 100H. By increasing the threshold value of the comparator (CMP) 326, it is possible to suppress a malfunction caused by vibration generated from a joint of the wrist when the wrist is bent or rotated. You will not be able to catch the right finger.

To solve this problem, the vibration generator (NM) 338 described above is provided.
It is located on the inner surface of wrist band 310 and is in contact with the skin surface. When the joint of the wrist is bent or turned, wrinkles are generated on the surface of the skin, and the vibration generator rubs against the vibration generator, so that the vibration generator (or wrist) at a specific frequency (hereinafter referred to as a wrist) (Referred to as vibration).

FIGS. 61A and 61B show examples of the structure of the vibration generator. The example shown in (a) is a sensor unit (S
S) Thin plastic plate (PF) on the lower surface of 312
The plastic plate 340 is affixed. When the plastic plate 340 rubs against the skin surface, a vibration having a frequency different from that of the finger tapping is generated, thereby facilitating the detection of the wrist movement.

In the example shown in (b), a small piece 34 of sponge, felt, or the like is placed on the inner surface (the side in contact with the arm) of the wrist band 310.
2, 344, or the entire inner surface of the wrist band 310 is made of these materials. Vibration occurs when these small pieces 342 and 344 rub against the skin surface.

As described above, the frequency of the vibration generated by the rubbing is in a region different from the frequency band generated by keying at the fingertip (hereinafter referred to as finger vibration). In the present embodiment, the vibration generator 100
A vibration generator that generates a frequency of 0 to 2000H is used.

FIG. 62 shows a band-pass filter (BPF1) 322 for detecting a fingering motion and a band-pass filter (BPF2) 324 for detecting a wrist motion used in the present embodiment.
3 shows an example of a pass frequency band.

In this embodiment, the vibration generator generates wrist vibration by rubbing against the skin. However, the present invention is not limited to this, and a plurality of vibration generators vibrate due to the movement of the wrist. Thus, it is possible to generate wrist vibration.

As described above, the wrist vibration generated from the vibration generator (NM) 338 is detected by the impact sensor (SN) 316 and the sensor amplifier (SA) 320 as shown in FIG. , And separated by a wrist motion detection bandpass filter (BPF2) 324. In the comparator setting mechanism (CPL) 328, the comparator (CPL) is set according to the magnitude of the input wrist vibration.
MP) 326 is controlled.

Specifically, when the wrist vibration is large, the threshold value of the comparator (CMP) 326 is set to be large, and when there is no or small wrist vibration,
The threshold value of the comparator (CMP) 326 is set small. Thereby, when wrist vibration is large, unnecessary 80 to 100 Hz generated due to wrist bending or rotating operation
Erroneous operation due to the above signal component can be avoided.

Further, when there is no or small wrist vibration, even a minute finger operation can be stably captured.

In the present embodiment, the threshold value of the comparator (CMP) 326 is raised or lowered to
Although the erroneous input is suppressed by the wrist motion, similar results can be obtained by other methods such as using a delay and a dead time.

As described above, according to the present embodiment, it is possible to easily detect wrist movement without installing a new wrist movement sensor. By using the configuration shown in the eleventh embodiment, the problem in the configuration shown in FIG. 57 in the tenth embodiment can be solved.

Here, as the details of the command generation by the fingering, the keying command FC is obtained from the keying timing information TYP.
A method of assembling the M will be described.

FIG. 63 shows a command assembling apparatus (CA
FIG. 8 is a diagram for explaining an example of a method of converting a keying timing signal TYP into a keying command FCM in M).

In the figure, the keying timing signal TYP is generated once for one keying, and its pulse width M is constant. Here, T1 and T2 are time constants for identification.

When a key is pressed with one of the fingertips and a pulse is generated, the pulse is generated with reference to the pulse rising time.
If the next pulse occurs within the time T1, it is regarded as "0", the reference time is returned to 0, and the next pulse is held.
If the next pulse occurs within 2 hours, it will be regarded as "1",
Return the reference time to 0 and wait for the next pulse. And T2
If the next pulse does not occur within the time, stop the pulse train analysis.

Therefore, FIGS. 63 (A) to 63 (D)
The time series keying timing signals TYP shown in FIG. 1 are “1”, “0, 1”, “1, 1”, “0, 1, 0, 1,.
It is converted into a keying command FCM of “1”.

As described above, according to the conversion method shown in FIG. 63, a sequence of "0" and "1" is created like a Morse code using the pulse generation time intervals. Note that, unlike the Morse code, in the conversion method shown in FIG. 63, the final code is always “1”.

In the method shown in FIG. 63, the pulse width M
Is constant, but using a part of the detection signal amplified by the sensor amplifier SA to detect the keying strength at the time of keying with a fingertip, and giving different pulse widths, Complex commands can be generated.

FIG. 64 shows a time-series keying command FCM and a corresponding command CC in this embodiment.
FIG. 6 is a diagram illustrating an example of M.

The keying command FCM needs to have a certain length in order to avoid erroneous operations due to ambient noise and normal operations such as mastication and conversation. However, operability can be improved by using a short keying command FCM for a dial or the like whose usage situation is clear, such as a numeral.

The generated keying command FCM is a command (CCM) based on the information in the code table (CTB).
Is converted and output.
