The fraudulent call alarm devices described in Patent Documents 1 and 2 are equipped with a tilt sensor to detect the tilt or operation of the main body. As a result of this detection, a warning sound is output. On the other hand, as the handset to which the fraudulent call alarm device is fixed has diversified functions and designs, the handset waiting to receive a call may be placed horizontally, or it may be placed upright as a handset. A very wide range of things.

When talking using a handset, the degree of inclination when lifting the handset varies depending on the user. For this reason, it may be difficult to reliably output the warning sound using the techniques described in Patent Documents 1 and 2. In view of the above, there is a demand for a configuration that can reliably output a warning sound even in various types of telephone receivers.

An object of the present invention is to provide an audio output device installed in a receiver of an audio communication device that can reliably output a warning sound, and further improve the effectiveness of the audio output device by collaborating with supporters. Our goal is to spread the word and help eradicate this unfortunate damage.

A voice output device according to the present invention is provided in a voice communication device that enables voice communication via a communication line between a first speaker and a second speaker who are separated from each other, and includes at least the voice uttered by the first speaker. is configured to collect the sound by a first microphone and output the speech voice of the second speaker by a first speaker, and the rear surface of the receiver part is on the opposite side to the side where the first microphone and the first speaker are provided. and a pair of side surfaces extending in an axial direction from the first speaker to the first microphone.

(First embodiment)
DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of an audio output device according to the present invention will be described below with reference to the drawings.

<Lineline phone configuration>
As shown in FIG. 1, a voice output device 100 according to a first embodiment of the present invention is applied to a fixed telephone (voice communication device) 200. The fixed telephone 200 includes a main body 210, a receiver (receiver) 220, and a cord 230.

The main body 210 is formed of a flat, substantially rectangular casing. The casing of main body 210 is made of resin. A plurality of buttons 211 are arranged on the right side of the top surface of the main body 210. When the button 211 is pressed by the user, the number of the destination to be called can be input. In the first embodiment, the buttons 211 are arranged in a matrix of 3×4, and each button 211 has a substantially circular shape, but the number, arrangement, shape, etc. are not limited thereto.

The receiver 220 is formed of a substantially rectangular parallelepiped housing. The housing of the handset 220 can be made of resin, for example. The handset 220 is placed on the left side of the top surface of the main body 210 and to the left of the button 211 so that its long axis is substantially parallel to the installation surface. A first end 221 and a second end 222 of the handset 220 each protrude toward the main body 210 (vertically downward) in the placed state. The first end 221 and the second end 222 can be fitted into corresponding recesses formed in the main body 210, respectively. These fittings prevent the handset 220 from slipping off the main body 210 in the placed state. Note that the placement position and posture of the handset 220, the shapes of the first end 221 and the second end 222, and the like are not limited to these. For example, the first end 221 and the second end 222 may not protrude as described above, and the lower surface of the receiver 220 may be flat.

The back surface 223 of the handset 220 becomes the top surface of the handset 220 in the placed state, and faces the user's palm when the handset 220 is held by the user. The back surface 223 has a curvature from the first end 221 to the second end 222 . The receiver 220 forms side surfaces 224 and 225 on the left and right sides. The back surface 223 supports an audio output device 100, which will be described in detail later. The telephone receiver 220 configured in this manner is such that the audio output device 100 can be grasped by the user and easily lifted up integrally with the audio output device 100 from the placed state. Note that the shapes of the back surface 223, the side surfaces 224, 225, etc. are not limited to these. For example, the back surface 223 may have no curvature as described above, and may be formed in a planar shape from the first end 221 to the second end 222.

The first end portion 221 has a built-in first speaker 221a. When the user holds the audio output device 100 and makes a call using the receiver 220, the first speaker 221a is placed at the first end 221 so as to face the user's ear. The first speaker 221a outputs speech from the other party. The second end portion 222 has a built-in first microphone 222a. When the user holds the audio output device 100 and speaks, the first microphone 222a is placed at the second end 222 so as to face the user's mouth. The first microphone 222a collects the user's speech. Note that the arrangement of the first speaker 221a and the first microphone 222a is not limited to this. The first speaker 221a and the first microphone 222a can be arranged arbitrarily as long as they are separated to some extent, and do not necessarily have to be arranged at both ends.

The cord 230 has an elastically deformable helical shape. The cord 230 is provided between the second end 222 of the handset 220 and the left side surface of the main body 210. A first speaker 221a and a first microphone 222a built into the handset 220 are electrically connected to a cord 230. A circuit board built into the main body 210 is electrically connected to the cord 230 and also to an external telephone network via a modular cable. Note that the communication mode is not limited to this. For example, wireless communication that does not require the cord 230 may be established between the main body 210 and the handset 220, or the main body 210 may be connected to an external Internet network via a LAN cable or Wi-Fi (registered trademark). may be connected to.

The landline telephone 200 configured as described above enables voice communication via a communication line between the user of the landline telephone 200 (first speaker) and another person (second speaker) who are separated from each other. shall be. When the handset 220 is held by the user via the audio output device 100 or directly held, the handset 220 collects the user's voice using the first microphone 222a, and also collects the voice uttered by another person. The signal is configured to be output from the first speaker 221a.

As shown in FIG. 2, the audio output device 100 includes a fitting 300 that attaches the housing 10 to the handset 220 by covering a portion of the handset 220. In the first embodiment, the receiver 220 is covered by the mount 300 so that the first end 221 (the first speaker 221a) and the second end 222 (the first microphone 222a) are exposed from the mount 300. Ru. One end of the fixture 300 penetrates into a portion of the housing 10 and is fixed thereto. The other end of the fixture 300 is coupled to a fixture 300a fixed to the housing 10. Thereby, the audio output device 100 is configured to be attached to the receiver 220. Since the housing 10 is not covered by the fixture 300 and is exposed, it can be grasped by the user. As the fixture 300, an elastic material, a fabric with a hook-and-loop fastener, thread, or the like can be used. FIG. 3 shows a state in which the audio output device 100 is attached to the receiver 220 and the sensing section 30 is pressed by the user. Since the sensing section 30 largely protrudes from the housing 10 as shown by the broken line in FIG. 3 when it is not pressed, the user can easily press the sensing section 30. The casing 10 has a substantially L-shaped cross section, and the mount 300 annularly biases the casing 10 to attach it to the receiver 220 . That is, the first covering portion 10a is biased toward the back surface 223 of the receiver, the second covering portion 10b is biased toward the side surface 224 (the end AL of the receiver), and the arrangement of the receiver 220 and the housing 10 is determined. has been done. As a result, the first sensing section 30 is located on the left side end 13L (left side surface 12), so it is located at the farthest left side, and is always able to protrude.

The coverage area of the receiver 220 and the audio output device 100 by the attachment 300 allows the audio output from the first speaker 221a, the audio collected to the first microphone 222a, and the audio output from the second speaker 20 to Any range is possible as long as it is not shielded. Here, "the sound is not blocked" means that the sound can be audibly propagated.

<Configuration of Audio Output Device>
As shown in Figures 4 and 5, the audio output device 100 includes a housing 10, a second speaker 2, a first sensing unit 30, a second sensing unit 31, a control unit 40, a recording unit 50, a second microphone 60, a third microphone 61, and an audio transmission unit 70.

As shown in FIG. 2, the housing 10 includes a first covering part 10a facing the back surface 223 of the receiving part, and a second covering part 10b facing one of the pair of side surfaces 224 and 225 of the receiving part. A connecting portion 10c that connects the two is defined, and an upper surface 11, a left side surface 12, and a lower surface 13 are defined.
The longitudinal direction of the housing 10 corresponds to the front-rear direction indicated by arrows in each figure.
As shown in FIG. 6(a), a second speaker 20 is provided at the rear end of the upper surface 11 and approximately at the center in the left-right direction. The second speaker 20 is a general-purpose speaker that includes a moving coil, a diaphragm, etc. built into the housing 10. The second speaker 20 is configured to convert an electrical signal from the control unit 40 and output audio upward from the top surface 11.

As shown in FIG. 2, a first sensing section 30 is provided on the left side surface 12 (second surface) of the housing 10. The square columnar first sensing section 30 extends in the front-rear direction along the left side surface 12. The sensing portion is supported so as to be able to reciprocate (or pivot) by a spring biasing member (not shown), and moves between the most protruding protruding position and the most retracted position. A control section 40, which will be described later, receives an activation signal at a position other than the protruding position. When the housing 10 is gripped by the user, the first sensing unit 30 is pressed by a part of the user's body in response to the grip, and senses the pressing. The first sensing unit 30 can be configured with a capacitive touch sensor, a load cell that senses a load, a press-type physical switch (such as a push button), and when pressed by the user, detects an electrical signal. is sent to the control unit 40. The first sensing section 30 is arranged on the left side surface 12 and has a substantially rectangular shape, but the number, arrangement, shape, etc. are not limited thereto.

In addition, in the first sensing part 30, in order to be easily operated by the user, for example, the pressing area occupying the left side surface 12 is made relatively large, and the first sensing part 30 is covered with a fitting 300 as in a third embodiment described later. The configuration may be such that pressure can be sensed even when the pressure is applied. In addition, when the first sensing section 30 is covered with the fixture 300, the color of the fixture 300 is a transparent color so that the first sensing section 30 can be easily recognized, and the first sensing section 30 has a color that can be visually recognized. may be added. Further, the first sensing portion 30 may be formed on the same plane as the left side surface 12 to suppress the sense of discomfort in terms of design.

In the first embodiment, the first sensing section 30 is provided on the left side surface 12; however, the present invention is not limited to this, and when the user lifts up the handset 220 via the housing 10, the housing 10 is gripped. At the same time, it is only necessary that the user's fingers, palm, or the like can press (contact) the outer surface of the first sensing section 30 . Therefore, the first sensing section 30 may be provided on any surface of the housing 10 other than the lower surface 13. As in the modified example shown in FIG. 15, the first sensing section 30 extends from the front side of the housing 10 in the front direction of the housing 10, and is bent to extend outward from the left side surface 12 of the housing in a first direction. It may extend along the

As shown in FIG. 6(b), the housing 10 is attached to the handset 220 so that the lower surface 13 (first surface) is in contact with a part of the back surface 223 of the handset 220. As shown in FIG. 6(b), in the handset 220, an area A, an axis K, and handset ends AL and AR (receiver ends) are defined. Region A is a part of the back surface 223 and is a portion facing the lower surface 13. In other words, the lower surface 13 faces the area A on the back surface 223 (see FIG. 14) of the receiver 220, which is opposite to the surface where the first microphone 222a and the first speaker 221a are provided. The axis K is an axis in the direction from the first speaker 221a to the first microphone 222a, and the direction of the axis K is the same as the front-rear direction. The handset ends AL and AR are ends in the region A in a direction perpendicular to the direction of the axis K and moving away from the axis K (first direction, left-right direction). That is, the handset end AL is the left end of area A, and the handset end AR is the right end of area A.

In the first embodiment, the lower surface 13 and the area A may be in contact with each other when the housing 10 is attached to the receiver 220, but instead of this, as shown in FIG. An intervening member 16 may be arranged between the lower surface 13 and the area A. The intervening member 16 is preferably made of an elastic or viscous material such as sponge, rubber, or alpha gel, but may also be a solid material such as cement or adhesive, or a glue or film such as double-sided tape. These materials have the property of deforming when pressed to match the shape of the contact portion with the other party. By deforming, it suppresses misalignment caused by external forces, and provides vibration-proofing and protection functions through its restoring force.
If the attachment 300 shown in FIGS. 3, 19, and 23 is made of an elastic material such as rubber, the tension of the attachment 300 and the restoring force of the intervening member 16 work together to increase the biasing effect, and the receiver of the housing 10 The attachment support to 220 becomes stronger.

The control section 40 and the recording section 50 are built inside the housing 10. The control section 40 has a microcomputer, an electric circuit, etc., and the recording section 50 has a memory, an electric circuit, etc.

As shown in FIG. 4, the control unit 40 controls the second speaker 20, the first sensing unit 30, the second sensing unit 31, the recording unit 50, the second microphone 60, the third microphone 61, and their driving sources. They are each electrically connected to a battery (not shown). The battery may be replaceable, such as a button battery, or may be a rechargeable battery that does not require replacement. Further, instead of installing a battery, the power supply to the fixed telephone 200 may be branched, and the branched power may be used as a driving power source. The control unit 40 receives the electrical signal sent from the first sensing unit 30 or the second sensing unit 31, and outputs audio through the second speaker 20 and records through the second microphone 60 and third microphone 61. It is configured to control audio recording in the unit 50. That is, when the first sensing unit 30 or the second sensing unit 31 detects a press, the control unit 40 outputs audio to the second speaker 20 and records audio to the recording unit 50 as a control process. instruct.

The memory of the recording unit 50 stores first audio data, programs, etc. corresponding to the audio output from the second speaker 20, and can be read and referenced by the microcomputer of the control unit 40. The first audio data includes data corresponding to the first sensing section and data corresponding to the second sensing section. The recording unit 50 is electrically connected to the second microphone 60 via the control unit 40 and an interface, and records second audio data corresponding to the spoken voice collected by the second microphone 60 in a memory. configured to be possible. The second microphone 60 picks up the other party's voice, while the third microphone 61 picks up the user's voice. Because the second microphone 60 has a configuration that makes it difficult to collect the user's voice, the third microphone 61 is placed near the user's mouth (near the first microphone). Even when the sensing part 30 is pressed to the retreat position, there is a step as shown in FIG. 3, and the third microphone 61 is not blocked by any part of the body. Since it can record the user's real voice, it also functions as a substitute for taking notes.

The first audio data includes first sensing unit corresponding data corresponding to a warning sound for warning another person (second speaker) over the fixed telephone 200. The warning sound is, for example, the sound of a message intended to discourage malicious intent, and specifically includes, but is not limited to, "the call will be recorded." Note that only one type of warning sound or multiple types of warning sounds may be output. When multiple types of warning sounds are used, for example, multiple types of first audio data are stored in advance in the memory of the recording unit 50, and the warning sounds are output depending on the length of time the sensing unit 30 is pressed, the number of times the sensing unit 30 is pressed, etc. It may also be possible to select/switch. Alternatively, the first sensing section 30 is provided with the same number of buttons as the types of audio data, and instructs switching of the output audio by pressing each button corresponding to a plurality of audio data. You can.

The second voice data is the voice uttered by another person (second speaker) over the landline telephone 200, which is output from the first speaker 221a and collected by the second microphone 60, and the third voice. Data that corresponds to the user's (first speaker's) uttered voice collected by the microphone 61 and the voice collected by the second microphone 60 and the voice collected by the third microphone 61. It is. The second audio data recorded in the recording unit 50 can be extracted from the memory, can be reproduced using another audio reproducing device, etc., or can be output from the second speaker 20 by operating an operation unit (not shown). But that's fine.

In the program, the control unit 40 executes the audio output of the first audio data and the audio recording of the second audio data in response to the pressure detection of the first sensing unit 30. There is.

FIG. 5(a) is a longitudinal cross-sectional view of the audio output device 100 taken along the axis K. FIG. FIG. 5(b) is a bottom view of the audio output device 100. The second microphone 60 and the audio transmission section 70 are arranged inside the housing 10. The audio transmission section 70 includes a rim section 70a, a diaphragm section 71, and a pipe section 72. The rim portion 70a is disposed at the edge of the circular through hole 13a on the front side of the substantially central portion of the lower surface 13. The diaphragm portion 71 is exposed through the circular through hole 13a of the lower surface 13 and connected to the area A of the receiver 220 via the rim portion 70a disposed on the lower surface 13 of the housing 10. One end of the pipe section 72 is connected to the diaphragm section 71, and the other end of the pipe section 72 is connected to the second microphone 60. As a result, the sound from the first speaker 221a is amplified by the diaphragm section 71 from the area A of the receiver 220, transmitted through the pipe section 72, and reaches the second microphone 60. That is, the audio transmission unit 70 is connected to the receiver 220 and is configured to transmit the uttered audio output from the first speaker 221a to the second microphone 60. The rim portion 70a exposed from the lower surface 13 is brought into close contact with the surface of the area A of the handset 220 due to the expansion and contraction force of the above-mentioned mount 300, making it possible to collect sound from the handset 220 with high efficiency.

<Operation of audio output device>
FIG. 8 is a flowchart showing the operation of the audio output device 100. As shown in FIG. 8, in a state where the audio output device 100 of the first embodiment is applied to the fixed telephone 200, first, the process starts from step 600. Next, in step 601, the user determines whether there is a call to fixed telephone 200. Unless there is a call to the fixed telephone 200, the determination is "No" and the process remains at step 601. On the other hand, if there is a call to fixed telephone 200, the determination is "Yes" and the process proceeds to step 602.

In step 602, the user lifts the receiver 220 from the main body 210 and positions the first end 221 and the second end 222 near the ear and mouth, respectively. As shown in FIG. 3, in the housing 10 of the audio output device 100, the left end 13L is located to the left of the receiver end AL. Therefore, when the user tries to pick up the handset 220, the user is forced to hold the handset 220 by holding only the casing 10 or while holding the casing 10 together. In other words, the parts other than the casing 10 become the first end 221 or the second end 222, making it impossible to stably grip a narrow area. becomes. When the user grips the housing 10, the user presses the first sensing section 30 with the user's fingers using the gripping force.

Next, in step 603, upon sensing that the first sensing section 30 is pressed, the control section 40 outputs the audio based on the data corresponding to the first sensing section in the first audio data, and outputs the second audio. Start audio recording of data.

Next, in step 604, a conversation is conducted between the user and the other person over landline telephone 200. At this time, the second speaker 20 outputs a warning sound corresponding to the first audio data. The warning sound output from the second speaker 20 echoes on the user's palm, etc., and reaches the first microphone 222a. The arrived warning sound is collected by the first microphone 222a and transmitted to the other person over the landline telephone 200 together with the user's uttered voice. At the same time, the spoken voice output from the first speaker 221a is transmitted by the voice transmitting section 70 and reaches the second microphone 60. The reached uttered voice is collected by the second microphone 60 and recorded in the recording unit 50 as second voice data together with the user's uttered voice collected by the third microphone 61.

Then, in step 605, the conversation between the user and the other person via the fixed telephone 200 is completed, the receiver 220 is placed on the main body 210, and the user's hand is released from the casing 10 that was being held. As a result, the finger moves away from the sensing section 30 and the pressure is no longer detected, and the control section 40 completes the audio output of the first audio data and the audio recording of the second audio data.

FIG. 9 is a partial sectional view showing a state in which the handset 220 is placed on the handset holder (main body 210). When the handset 220 is not used, it is placed in this state. A second sensing section 31 is arranged on the upper surface 11 of the housing 10. The speaker 221a of the handset 220 contacts the speaker receiving part of the handset holder due to its own weight, and the vicinity of the microphone 222a of the handset 220 contacts the microphone receiving part of the handset holder due to its own weight, so that the handset 220 is placed in a stable state. The housing 10 of the audio output device 100 is disposed on the back surface 223 of the handset 220, and is attached to the handset by annularly covering a part of the handset 220 using a fitting 300. An intervening member 16 is disposed that deforms according to the shape of the contact portion.

FIG. 10 is a partial cross-sectional view of the vicinity of the audio output device 100 in FIG. A sensor 32 is disposed inside the second sensing section 31 in the housing 10, and a probe 33 is provided on the side of the second sensing section 31 from the sensor 32. Before operation, a gap δ is ensured between the second sensing section 31 and the probe 33, as shown on the left side of FIG. When the second sensing part 31 is pressed, the probe 33 and the second sensing part 31 are pressed, and under the control of the control part 40 electrically connected to the sensor 32, the second sensing part in the recording part 50 is transmitted from the second speaker 20 to the second sensing part in the recording part 50. An alarm sound based on the X.31 compatible data is output. The alarm sound here is not a verbal output to warn the second speaker when the first sensing unit 30 senses it, but a loud warning siren that alerts the surroundings to the emergency situation. As shown in FIG. 12(a), it may be a verbal voice such as "Police officer will be soon" that discourages the target's malicious intentions. This not only makes the target person flinch in the residence, but also sends a message to the surrounding area, helping to ensure safety. FIG. 12(b) is a flowchart showing the operation when the user operates the second sensing section. As shown in FIG. 12(b), the alarm sound may be output until the battery is removed, but the invention is not limited to this, and the output may be stopped when the user performs a predetermined operation.

The left side of FIG. 10 shows a state in which the second sensing section 31 is not sensing. The second sensing portion 31 is provided on the upper surface 11 of the housing 10 and is integrally provided with the upper surface 11 via a low-strength portion 31a buried within the housing 10. The second sensing portion 31 protrudes upward from the upper surface 11, thereby increasing visibility. If the second sensing part 31 is hit from top to bottom with a fist or the like, the low strength part 31a will be damaged as shown in the right diagram of FIG. As a result, the second sensing section 31 moves and interferes with the probe 33, and as a result, under the control of the control section 40, an alarm siren is emitted based on the data corresponding to the second sensing section 31 in the recording section 50. Since the low-strength part 31a (damaged part) is buried and arranged, the broken part and the fist do not come into contact. In addition, as shown in the right figure, the amount by which the probe 33 is pressed is ensured by setting the height of the second sensing section 31. In addition, as described above, the handset 220 is placed on the handset holder (main body 210) in a stable state, and the audio output device 100 is attached to the handset 220 in a stable state, so that the handset 220 can be held in a stable state. Even if the second sensing part 31 is hit with a fist or the like while the handset is placed in the handset holder, it is stable enough to prevent failures in the operation of the second sensing part 31 such as misalignment or falling off of the handset or this device.

FIG. 11 shows a state in which the audio output device 100 is attached to a handset 240, which is a wireless receiver of a fixed telephone 200. Since the handset 240 is placed upright, its support with the holder is unstable, and it is difficult to press the second sensing portion 31 instantly while it is placed. As an example of use for solving this problem, after grasping the handset 240, the second sensing part 31 is collided with a desk or the like in order to press the second sensing part 31, and the state shown on the right side of FIG. 10 is created. As a result, a warning siren is instantaneously issued based on the data corresponding to the second sensing section 31.

The second sensing unit 31 is effective not only when the user encounters danger at home as described above, but also when, for example, an emergency is felt in the body. Issuing a warning siren is a means of calling for help from the surrounding area. In addition to residences, it is also effective in customer service situations such as stores. If this device is installed and painted in a way that makes it stand out, it will act as a deterrent to the target person and provide a crime prevention effect.

(Modified example)
FIG. 16 is a perspective view showing a modification of the audio output device 100 according to the first embodiment. As shown in FIG. 16, the audio output device 100 can also be configured without the second sensing section 31. Note that, on the contrary, the audio output device 100 may have a configuration in which the first sensing section 30 is not provided, but the second sensing section 31 is provided. FIG. 17 is a side view of the audio output device 100 shown in FIG. 16. FIG. 18 is a perspective view showing an example in which the audio output device 100 shown in FIG. 16 is applied to an intercom. In this way, the audio output device 100 of the present application can also be applied to an intercom. FIG. 19 is a side view showing a state in which the audio output device 100 shown in FIG. 16 is attached to a receiver 220 of a different shape. As shown in FIG. 19, the audio output device 100 can be applied to receivers 220 of various shapes.

20 and 21, the audio output device 100 shown in FIG. 16 includes a housing 10, a second speaker 20, a sensing section (first sensing section) 30, a control section 40, a recording section 50, a second microphone 60 and a voice transmission section 70. In FIGS. 20 and 21, front/back directions, left/right directions, and up/down directions respectively correspond to front/back directions, left/right directions, and up/down directions indicated by arrows.

The housing 10 has a substantially rectangular parallelepiped shape, and has an upper surface 11, a left side surface 12, and a lower surface 13, respectively. The longitudinal direction of the housing 10 corresponds to the front-rear direction. A second speaker 20 is provided at the rear end of the upper surface 11 and approximately at the center in the left-right direction. The second speaker 20 is a general-purpose speaker that includes a moving coil, a diaphragm, etc. built into the housing 10. The second speaker 20 converts the electrical signal from the control unit 40 and outputs audio upward from the top surface 11.

A sensing section 30 is provided on the left side surface 12 (second surface), which is a surface of the housing 10 that is different from the lower surface 13 (first surface). The rectangular sensing section 30 extends in the front-rear direction along the left side surface 12. The sensing unit 30 is configured to be pressed by a part of the user's body in response to the gripping when the housing 10 is gripped by the user, and to sense the pressing. The sensing unit 30 is a capacitive touch sensor, a load cell that senses a load, a press-type physical switch (such as a push button), and when pressed by the user, sends a detected electrical signal to the control unit 40. It is supposed to be done. In this modification, the sensing section 30 is arranged on the left side surface 12 and has a substantially rectangular shape, but the number, arrangement, shape, etc. are not limited thereto.

Further, in order to be easily operated by the user, the sensing section 30 has, for example, a relatively large pressing area on the left side surface 12, so that it can detect pressing even when covered with the fixture 300. may be configured. Further, when the sensing part 30 is covered with the fixture 300, the color of the fixture 300 may be a transparent color and the sensing part 30 may be colored in a visible manner so that the sensing part 30 can be easily recognized. good. Further, a through hole may be provided in the fixture 300 corresponding to the location where the sensing unit 30 is arranged so that the sensing unit 30 is exposed from the fixture 300. Furthermore, the sensing portion 30 may be configured to protrude from the left side surface 12 to some extent so that the feeling of pressure can be easily confirmed, or the sensing portion 30 may be configured to be flush with the left side surface 12 to suppress the sense of discomfort in terms of design. It may be formed into

In this modification, the sensing unit 30 is provided on the left side surface 12, but the present invention is not limited to this. When the user lifts up the handset 220 via the housing 10, the housing 10 is grasped and It is only necessary that the user's fingers, palm, or the like can press (contact) the outer surface of the sensing section 30 . Therefore, the sensing section 30 may be provided on any surface of the housing 10 that is different from the lower surface 13.

In this modification, when the housing 10 is supported by the receiver 220, the lower surface 13 and the area A are in contact with each other. A member may be interposed. For example, from the viewpoint of promoting vibration propagation between the lower surface 13 and the region A, it is effective to set the acoustic impedance of the predetermined member close to that of the material of the housing 10 and the receiver 220. On the other hand, from the viewpoint of suppressing the vibration propagation, it is effective to make the acoustic impedance of the predetermined member different from that of the material of the housing 10 and the receiver 220.

The control section 40 and the recording section 50 are built inside the housing 10. The control section 40 has a microcomputer, an electric circuit, etc., and the recording section 50 has a memory, an electric circuit, etc.

As shown in FIG. 20, the control unit 40 electrically connects the second speaker 20, the sensing unit 30, the recording unit 50, the second microphone 60, and a battery (not shown) that serves as a driving source for these. It is connected. The battery may be replaceable, such as a button battery, or may be a rechargeable battery that does not require replacement. Further, instead of installing a battery, the power supply to the fixed telephone 200 may be branched, and the branched power may be used as a driving power source. The control unit 40 receives the electric signal sent from the sensing unit 30 and controls audio output via the second speaker 20 and audio recording at the recording unit 50 via the second microphone 60. It has become. That is, when the sensing unit 30 detects a press, the control unit 40 instructs the second speaker 20 to output audio and record the audio to the recording unit 50 as control processing.

The memory of the recording unit 50 stores first audio data, programs, etc. corresponding to the audio output from the second speaker 20, and can be read and referenced by the microcomputer of the control unit 40. The recording unit 50 is electrically connected to the second microphone 60 via the control unit 40 and the interface, and stores second audio data corresponding to the spoken voice collected by the second microphone 60 in the memory. It is configured so that it can be recorded.

The first audio data is data corresponding to a warning sound for warning another person (second speaker) over the fixed telephone 200. The warning sound is, for example, the sound of a message intended to discourage malicious intent, and is not limited to, specifically, "the call will be recorded." Note that only one type of warning sound or multiple types of warning sounds may be output. When multiple types of warning sounds are used, for example, multiple types of first audio data are stored in advance in the memory of the recording unit 50, and the warning sounds are output depending on the length of time the sensing unit 30 is pressed, the number of times the sensing unit 30 is pressed, etc. It may also be possible to select/switch. Alternatively, the sensing section 30 may be provided with the same number of buttons as the types of audio data, and instruct the switching of the output audio by pressing each button corresponding to a plurality of audio data. good.

The second voice data is voice uttered by another person (second speaker) over the landline telephone 200, and includes the voice output from the first speaker 221a and collected by the second microphone 60, and the user ( This data corresponds to the voice uttered by the first speaker (first speaker) and the voice collected by the second microphone 60. The second audio data recorded in the recording unit 50 can be extracted from the memory and can be reproduced using another audio reproducing device or the like.

In the program, the controller 40 executes the audio output of the first audio data and the audio recording of the second audio data in response to the pressure sensing by the sensor 30.

FIG. 21(a) is a longitudinal cross-sectional view of the audio output device 100 cut in the front-rear direction. FIG. 21(b) is a bottom view of the audio output device 100. The second microphone 60 and the audio transmission section 70 are arranged inside the housing 10. The audio transmission section 70 includes a rim section 70a, a diaphragm section 71, and a pipe section 72. The rim portion 70a is disposed at the edge of the circular through hole 13a on the front side of the substantially central portion of the lower surface 13. The diaphragm portion 71 is exposed through the circular through hole 13a of the lower surface 13 and connected to the area A of the receiver 220 via the rim portion 70a disposed on the lower surface 13 of the housing 10. One end of the pipe section 72 is connected to the diaphragm section 71, and the other end of the pipe section 72 is connected to the second microphone 60. As a result, the sound from the first speaker 221a is amplified by the diaphragm section 71 from the area A of the receiver 220, transmitted through the pipe section 72, and reaches the second microphone 60. That is, the audio transmission unit 70 is connected to the receiver 220 and is configured to transmit the uttered audio output from the first speaker 221a to the second microphone 60. The rim portion 70a exposed from the lower surface 13 is brought into close contact with the surface of the area A of the handset 220 due to the expansion and contraction force of the above-mentioned mount 300, making it possible to collect sound from the handset 220 with high efficiency.

FIG. 22 is a flowchart showing the operation of the audio output device 100 according to this modification. As shown in FIG. 22, in a state where the audio output device 100 is applied to the fixed telephone 200, the process starts from step 600. Next, in step 601, the user determines whether there is a call to fixed telephone 200. Unless there is a call to the fixed telephone 200, the determination is "No" and the process remains at step 601. On the other hand, if there is a call to fixed telephone 200, the determination is "Yes" and the process proceeds to step 602.

In step 602, the user lifts the receiver 220 from the main body 210 and positions the first end 221 and the second end 222 near the ear and mouth, respectively. In the housing 10 of the audio output device 100, the left end portion 13L is located to the left of the receiver end AL. Therefore, when the user tries to pick up the handset 220, the user is forced to hold the handset 220 by holding only the casing 10 or while holding the casing 10 together. In other words, the parts other than the casing 10 become the first end 221 or the second end 222, making it impossible to stably grip a narrow area. becomes. When the user grips the housing 10, the user presses the sensing section 30 with the user's fingers using the gripping force.

Next, in step 603, upon sensing that the sensing unit 30 is pressed, the control unit 40 starts audio output of the first audio data and audio recording of the second audio data.

Next, in step 604, a conversation is conducted between the user and the other person over landline telephone 200. At this time, the second speaker 20 outputs a warning sound corresponding to the first audio data. The warning sound output from the second speaker 20 echoes on the user's palm, etc., and reaches the first microphone 222a. The arrived warning sound is collected by the first microphone 222a and transmitted to the other person over the landline telephone 200 together with the user's uttered voice. At the same time, the spoken voice output from the first speaker 221a is transmitted by the voice transmitting section 70 and reaches the second microphone 60. The reached speech sound is collected by the second microphone 60 and recorded in the recording unit 50 as second sound data together with the user's speech sound.

Then, in step 605, the conversation between the user and the other person via the fixed telephone 200 is completed, the receiver 220 is placed on the main body 210, and the user's hand is released from the casing 10 that was being held. As a result, the finger moves away from the sensing section 30 and the pressure is no longer detected, and the control section 40 completes the audio output of the first audio data and the audio recording of the second audio data.

<Effects of the first embodiment>
As explained above, according to the audio output device 100 according to the first embodiment of the present invention and its modification, the housing 10 of the audio output device 100 supported by the receiver 220 is connected to the user (first speaker). It is designed to be held by When the housing 10 is gripped by the user's hand, the first sensing unit 30 is pressed by a part of the user's body in response to the grip, and the pressing is sensed. Then, based on the pressure sensing by the first sensing section 30, a warning sound is output from the second speaker 20. Therefore, the warning sound can be output more reliably than when the motion of the handset itself is detected using a motion sensor such as a tilt sensor disclosed in Patent Document 1 or Patent Document 2, for example.

In particular, even if the user is inexperienced with the machine (for example, an elderly person), the warning sound can be output from the second speaker 20 without any special operation. Therefore, it is possible to more reliably prompt a warning to a malicious person using the fixed telephone 200.

Furthermore, the housing 10 has a lower surface 13 (first surface) that faces the area A of the handset 220, and the sensing section 30 has a lower surface 13 (first surface) that faces the region A of the receiver 220, and the sensing section 30 has a lower surface 13 (second surface) that is different from the lower surface 13 (first surface). ). When the user grips the housing 10, the second surface may be a part of the user's body such as a finger or a palm that is likely to be pressed or a part that cannot be forced to be pressed due to its structure. According to this, the first sensing section 30 can be installed in a region that is easily pressed or a region that cannot be forced to be pressed due to its structure. Therefore, when the housing 10 is gripped, the first sensing section 30 can be pressed more reliably. By setting the load that the first sensing section 30 senses to be lower than the load required to grip the earpiece, in order to grip the earpiece, the user will naturally have to grip the earpiece with a load greater than the set load. 1 sensing section 30 can always sense when gripping.

Furthermore, the housing 10 has a lower surface 13 (first surface) that faces the area A of the handset 220, and in the handset 220, an axis K and handset ends AL and AR are defined, respectively. As shown in FIG. 3, the first surface has a left end 13L (first end) and a right end 13R (first end), and the left end 13L is the end of the receiver in the left direction. It is located further away from the axis K (to the left) than the section AL. That is, the first covering part 10a is biased toward the back surface 223 of the handset, the second covering part 10b is biased toward the side surface 224 (handset end AL), and the arrangement of the handset 220 and the housing 10 is determined. However, since the first sensing section 30 is disposed above the left end section 13L, it is located at the farthest left side. According to this, when the receiver 220 is picked up by the user, the casing 10 can be configured to be easily grasped or to be forced to be grasped due to the structure. Therefore, when the handset 220 is lifted, the housing 10 can be gripped more reliably, and the first sensing section 30 can sense it.

The audio output device 100 also includes a mounting fixture 300 that attaches the housing 10 to the handset 220 by covering a part of the handset 220 and a part of the housing 10. According to this, the housing 10 can be supported on the telephone receiver 220 easily and reliably by the mounting tool 300. In Patent Documents 1 and 2, there is a risk of it coming off because it is attached, but this risk of coming off can be suppressed.

In addition, the other configurations of the fixture 300 and the audio output device 100 can utilize inexpensive parts and materials, have a simple configuration, and suppress manufacturing costs, so they can be made very inexpensive as a whole. Can be done.

The fixture 300 may be made of a stretchable material. In this case, the elastic restoring force of the stretchable material can be utilized, making it possible to easily attach and detach the attachment 300 to and from the handset 220 and the housing 10. and can be securely held in the housing 10. Furthermore, when attaching the fixture 300 to the handset 220 and the housing 10, the relative arrangement of the housing 10 to the handset 220 can be easily adjusted and changed any number of times.

Furthermore, in the first embodiment, the audio output device 100 includes a second microphone 60 that collects the spoken voice output from the first speaker 221a, a third microphone 61 that collects the user's real voice, and a second microphone 61 that collects the user's real voice. 60 and a recording unit 50 that records the speech sounds collected by the third microphone 61. In addition to controlling the output of the second speaker 20 , the control unit 40 performs recording control to record the speech voice collected by the second microphone 60 based on the sensing by the first sensing unit 30 . According to this, based on the pressure sensing by the first sensing section 30, the uttered voice can be recorded more reliably. Therefore, it is possible to record the voice uttered by another person over the malicious landline telephone 200 and securely preserve evidence. On the other hand, the alarm devices described in Patent Documents 1 and 2 are equipped with an inclination sensor to detect the inclination or operation of the main body, but the recording control for recording the spoken voice is stopped. The means is a timer. In the case of a timer, regardless of whether the call continues or ends, it is forcibly stopped when the set time is reached, resulting in excessive or insufficient recording of utterances and wasted power consumption, making it impossible to secure evidence. On the other hand, in the first embodiment, since it is possible to record only the period of the user's grasping of the housing 10 during a call, the evidence can be preserved in just the right amount, and there is no problem with the prior art described above. This point is a major advantage.

Furthermore, in the first embodiment and its modifications, the audio output device 100 includes the audio transmitting section 70 that is connected to the receiver 220 and transmits the uttered audio output from the first speaker 221a to the second microphone 60. According to this, the speech sound output from the first speaker 221a can be efficiently transmitted to the second microphone 60. Therefore, since the second microphone 60 can collect sound with high sensitivity, noise can be suppressed even if the output gain of the first speaker 221a is small. Furthermore, in Patent Document 1 and Patent Document 2, the sound collection section extends separately from the housing and is attached near the speaker of the receiver, so the sound collection section obstructs the use of the receiver, and it is difficult to remove the receiver. It had the disadvantage of being easy to use. In the first embodiment of the present invention, since the sound collection section is built into the housing 10, the above-mentioned drawbacks of the prior art can be overcome. Further, in Patent Documents 1 and 2, miniaturization of the device is required so as not to impair the operability of the telephone, but in the first embodiment, the need for miniaturization is limited due to the characteristics of gripping the casing 10. It is. Since the device can be made larger to a certain extent, the choice of parts is expanded and there is more leeway in layout design, which results in lower manufacturing costs and a more reliable design. In addition, by making the device larger to a certain extent, it is possible to install cheaper and easier-to-handle AAA or AA batteries instead of button batteries that are too small and difficult for elderly people to handle, making it easier to leave the device in a state where it cannot operate due to a dead battery. It is possible to suppress the risk of being exposed.

In addition, the audio output device 100 has a first covering portion 10a and a second covering portion 10b, and is attached to the receiver 220 by being biased in an annular shape using a flexible material, so anyone can easily attach it. - The first covering part 10a and the second covering part 10b are reliably urged toward the receiver 210, and stable support is established. Furthermore, as shown in FIG. 19, the handset 220 is stably supported regardless of its size and shape (elongated, curved, thick). Moreover, since the second covering part 10b is biased by the receiver 220, even if the first sensing part 30 is strongly pressed, the second covering part 10b serves as a load receiving part and does not shift. Further, it is possible to suppress the enlargement of the portion on the opposite side (right side) from the first covering portion 10a side.

The effect of installing the warning siren issuing function by the second sensing section 31 in this device is obtained by taking advantage of the characteristics of a telephone that is used on a daily basis. In other words, since normal emergency sirens are not used during normal times, there are few opportunities to check the condition of the device, and there is a risk of it being left in a malfunctioning state. On the other hand, with this device attached to the handset, each time the phone is used, it is inspected for any malfunctions, and if there is an abnormality such as a dead battery, it is easily repaired and maintained in good condition. Furthermore, since the handset is installed close to the user, immediate response is possible. In this device, the second sensing portion 31 is arranged on the top surface 11 of the device exposed to the outside on the side of the back surface 223 of the handset, so visibility is high and prompt operation is easy.

In addition, since the two surfaces (the first covering part 10a and the second covering part 10b) of the audio output device 100 are biased toward the receiver 220, the audio output device 100 is firmly supported by the receiver 220 and can be easily lifted up. It can withstand the accompanying inertial force and does not easily shift. Moreover, since the audio output device 100 of the first embodiment is arranged approximately in the center between the first speaker 221a and the first microphone 222a of the handset 220, the second sensing unit 31 is tapped while the handset 220 is placed in the handset holder. Even if the handset 220 is not removed from the holder. Further, the upper surface 11 on which the second sensing section 31 is disposed is an area that the user does not touch during use, and does not get in the way.

(Second embodiment)
FIG. 23 is a side view of the receiver 220 and the audio output device 100 according to the second embodiment of the present application, viewed from the front side. The second embodiment differs from the first embodiment in that the first sensing section 30 is provided on the right side surface of the first covering section 10a. The first sensing portion 30 protrudes further away from the axis K than the side surface of the handset 220 in the first direction. The configuration of the second embodiment also provides the same effects as the first embodiment. Also in the second embodiment, both the first sensing section 30 and the second sensing section 31 may be provided, but only one of them may be provided.

(Third embodiment)
FIG. 24(a) is a perspective view of a receiver 220 and an audio output device 100 according to a third embodiment of the present application. In the third embodiment, the fixture 300 has a cylindrical shape that communicates from the upper end 310 of the opening to the lower end 320 of the opening. The fixture 300 is made of a stretchable material, and the length of its long axis in the vertical direction is shorter than the length of the handset 220 in the long axis direction, and is approximately the same as the length of the audio output device 100 in the long axis direction. It has become. Note that the length of the fixture 300 in the major axis direction can be adjusted depending on the range of the above-mentioned covered area. The first sensing portion 30 is exposed through a long hole formed in the fixture 300 and protrudes outward. In the fixture 300, a gap or a hole that communicates between the inside and the outside is formed at a position corresponding to the third microphone 61 so as not to impede sound collection by the third microphone 61.

When covering the receiver 220 and the audio output device 100 with the fixture 300, first, the upper opening end 310 and the lower opening end 320 are expanded in the radial direction, and the first end 221 is inserted into the interior of the fixture 300 from the lower opening end 320. Infiltrate. Next, the first end 221 is exposed from the opening upper end 310, and the audio output device 100 is entered into the radially expanded state of the fixture 300 from either the opening upper end 310 or the opening lower end 320. . After placing the audio output device 100 at a predetermined location inside the fixture 300 so as to be in contact with the receiver 220, the restoring force of the fixture 300 is used to move the inner wall of the fixture 300 between the receiver 220 and the audio output device 100. to fit the outer surface of the The audio output device 100 is placed on the back surface 223 of the handset 220, and the audio output device 100 and the handset 220 are held by frictional force with the inner surface of the fixture 300. In this way, support of the audio output device 100 to the receiver 220 is achieved by covering it with the fixture 300.

The fixture 300 may have a through hole 330 near the opening lower end 320. It is preferable that the through hole 330 is located such that the second speaker 20 of the audio output device 100 is exposed outward through the through hole 330 in a state where the audio output device 100 is covered with the fixture 300. . Note that the through hole 330 may be a notch provided at the edge corresponding to the lower end 320 of the opening.

Examples of the elastic material constituting the fixture 300 include synthetic polymer materials such as silicone rubber, urethane rubber, NBR, synthetic latex, and elastomer (TPE, TPR), and natural polymers such as natural rubber and natural latex. It may be made of a type material, a net material, a cloth material, etc., but is not limited thereto. Further, the color of the fixture 300 is arbitrary, but for example, the material may be provided with a color that harmonizes with the appearance of the telephone receiver 220, visibility transparency, or the like. The functionality of the fixture 300 is also optional, but for example, it has high friction properties that prevent it from slipping when gripped, low thermal conductivity that makes you feel warm when you grip it, and impact resistance that easily absorbs and disperses shocks caused by external forces. The material may also have sterilizing and antibacterial properties.

In the third embodiment, the audio output device 100 is attached to the receiver 220 by covering both of them with the mounting tool 300, but instead of this, only the receiver 220 is covered with the cover. The audio output device 100 may be supported by being covered and connecting the audio output device 100 to the outer surface of the cover. Furthermore, the fixture 300 may not be used. Specifically, the audio output device 100 may be supported on the handset 220 using a connector that connects the handset 220 and the audio output device 100, an adhesive member, or the like.

The audio output device 100 according to the third embodiment can also be attached to a telephone receiver 220 that can be placed on the main body 210. For example, as shown in FIGS. A handset (receiver) 240 may be provided, and the audio output device 100 may be supported by the handset 240.

As shown in FIGS. 24(a) and 24(b), the handset 240 is formed of a substantially rectangular parallelepiped-shaped housing that extends uniaxially. The housing of slave device 240 is made of resin. In addition, in the handset 240, the same or equivalent components as those included in the main body 210 and the handset 220 are designated by the same reference numerals, and a description thereof will be omitted.

FIGS. 24(a) and 24(b) show a perspective view and a side view of the slave device 240. The handset 240 is configured so that it can be placed upright on a horizontal surface. When the handset 240 is placed on a horizontal surface, it is placed on the horizontal surface with the first end 221 on the first speaker 221a side facing upward and the second end 222 on the first microphone 222a side facing the bottom. Further, the handset 240 is separated from the main body 210 and is capable of wireless communication with the main body 210.

<Effects of the third embodiment>
As explained above, according to the audio output device 100 according to the third embodiment of the present invention, the housing 10 of the audio output device 100 supported by the receiver 220 is held by the user (first speaker). It looks like this. When the housing 10 is gripped by the user's hand, the sensing unit 30 is pressed by a part of the user's body in response to the grip, and the pressing is sensed. Then, based on the pressure sensing by the sensing unit 30, a warning sound is output from the second speaker 20. Therefore, the warning sound can be output more reliably than when the movement of the handset itself is detected using a motion sensor such as a tilt sensor.

In particular, even if the user is inexperienced with the machine (for example, an elderly person), the warning sound can be output from the second speaker 20 without any special operation. Therefore, it is possible to more reliably prompt a warning to a malicious person using the fixed telephone 200.

Further, in the third embodiment, the housing 10 has a lower surface 13 (first surface) that faces the area A of the handset 220, and the sensing section 30 has a lower surface 13 (first surface) that is different from the lower surface 13 (first surface). It is provided on the 10th surface (second surface). When the user grips the housing 10, the second surface may be a part of the user's body such as a finger or a palm that is likely to be pressed or a part that cannot be forced to be pressed due to its structure. According to this, the sensing section 30 can be installed in a region that is easily pressed or a region that cannot be forced to be pressed due to its structure. Therefore, when the housing 10 is gripped, the sensing portion 30 can be pressed more reliably. By setting the load that the sensing unit 30 senses to be lower than the load required to grip the earpiece, in order to grip the earpiece, the user must naturally grip the earpiece with a load greater than the set load, and therefore the sensing unit It can always be sensed when gripping.

Further, in the third embodiment, the housing 10 has a lower surface 13 (first surface) facing the area A of the handset 220, and in the handset 220, the axis K and the ends AL, AR of the handset are , respectively. The first surface has a left end 13L (first end) and a right end 13R (first end). Position yourself away from (to the left). According to this, when the receiver 220 is picked up by the user, the casing 10 can be configured to be easily grasped or so that it is forced to be grasped due to the structure. Therefore, when the receiver 220 is lifted, the housing 10 can be held more reliably.

Furthermore, in the third embodiment, the audio output device 100 includes a fitting 300 that supports the housing 10 on the handset 220 by covering a part of the handset 220 and a part of the housing 10. . According to this, the housing 10 can be supported on the telephone receiver 220 easily and reliably by the mounting tool 300. In Patent Documents 1 and 2, there is a risk of it coming off because it is attached, but this risk of coming off can be suppressed.

In addition, the mount 300 makes it easier to hold the handset 220 and the housing 10, protects the handset 220 and the housing 10, and improves the design. It is possible to have a structure that supports the The structure of the fixture 300 that supports the housing 10 is arbitrary, but for example, the fixture 300 may cover the housing 10 along with the receiver 220, or the housing 10 may be fastened to the fixture 300 that covers the receiver 220. Can be done. While having such a structure of the fixture 300, a through hole 330 may be provided at a portion corresponding to the second speaker 20, for example.

Therefore, as an effect of the third embodiment, it is possible to realize a mounting fixture 300 in which the housing 10 can be reliably supported by the telephone receiver 220, and the warning sound is not easily blocked by the through hole 330. Furthermore, the other configurations of the fixture 300 and the audio output device 100 can utilize inexpensive parts and materials, have a simple configuration, and suppress manufacturing costs, so they can be made very inexpensive overall. Can be done.

Furthermore, the fixture 300 may be made of a stretchable material. In this case, the elastic restoring force of the stretchable material can be utilized, making it possible to easily attach and detach the attachment 300 to and from the handset 220 and the housing 10. and can be securely held in the housing 10. Furthermore, when attaching the fixture 300 to the handset 220 and the housing 10, the relative position of the housing 10 to the handset 220 can be easily adjusted and changed.

Furthermore, in the third embodiment, the audio output device 100 includes a second microphone 60 that collects the speech sound output from the first speaker 221a, and a recorder that records the speech sound collected by the second microphone 60. 50. In addition to controlling the output of the second speaker 20 , the control unit 40 performs recording control to record the speech voice collected by the second microphone 60 based on the sensing by the first sensing unit 30 . According to this, based on the pressure sensing by the first sensing section 30, the uttered voice can be recorded more reliably. Therefore, it is possible to record the voice uttered by another person over the malicious landline telephone 200 and securely preserve evidence. In contrast, the alarm devices described in Patent Documents 1 and 2 are equipped with an inclination sensor to detect the inclination or operation of the main body, but the recording control for recording the spoken voice is stopped. The means is a timer. In the case of a timer, regardless of whether the call continues or ends, it is forcibly stopped when the set time is reached, resulting in excessive or insufficient recording of utterances and wasted power consumption, making it impossible to secure evidence. On the other hand, in the third embodiment, since it is possible to record only the period of the user's grasping of the casing 10 during a call, the evidence is preserved in just the right amount, and there is no problem with the prior art described above. This point is a major advantage.

(Background of the invention)
The inventors have recognized that there is room for improvement (issues) in the prior art in the ambiguity of motion sensing by tilt sensors and in recording relying on timers.
The receiver is held close to the user's ear and mouth. The inventor wondered whether this action of grasping could be utilized, and realized that if the grasping force was used as the cause of the output and input of the device, it would be possible to reliably generate a warning sound and record the voice of a call. First, the part of the handset 220 to be held was considered. Gripping the front and rear (axis K) direction ends is difficult compared to the size of the fingers. In addition, when holding the phone in the vertical direction, it is a meaningless and troublesome act to put the hands between the holder (main body 210) and the handset 220 from the placed state, and there is also a feeling of discomfort when the hands touch the face. On the other hand, gripping in the left-right direction (first direction) is a very natural gripping direction based on common sense. Therefore, we attempted to solve the problem by focusing on "grasping in the left and right direction."
As can be seen from the prior art (Patent Document 1, Patent Document 2), there is a common sense (hindering factor) that the device should be miniaturized so that it cannot be touched when being held. Going against this common sense, we attempted to make the phone larger so that one of the left and right sides extends from the receiver so that it can be touched when held.
As a result, the casing of the device gains grip strength, making it possible to reliably emit a warning sound based on the grip and to record calls without excess or deficiency, thus solving the two problems of the prior art at once.
Furthermore, the inventor provided the device's casing with a portion that covers one side of the receiver. As a result, it was possible to determine the arrangement in which the first sensing part could be easily pressed, and it was also possible to suppress the increase in size of the opposite side of the covering part. In addition, it has achieved multiple benefits such as being able to easily attach to a variety of handset shapes.
Furthermore, the inventor focused on the fact that the handset is always close to the user and that the device can be attached stably and firmly to the handset, and added an emergency siren function with a second sensing part that can respond immediately by tapping. did. The emergency siren function can be expected to minimize damage and prevent harm not only in residential accidents but also in customer service situations such as stores.
Unlike replacing a phone with a security feature or installing additional devices, this device can be easily retrofitted to a handheld handset and does not require any special settings or operations, making it easy for elderly people to accept.
