Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile phone device that transmits a detected sound to a caller.
[0002]
[Prior art]
There are times when the owner of the mobile phone device wants to know what state (location, environment, etc.) the user is in. Normally, the user dials a call to the portable telephone device, or sends a mail and waits for a reply. However, when there is no response, it is impossible to know the state of the other party. Therefore, regarding the position, it has been considered that the current position of the portable telephone device is transmitted to the telephone device of the called party by dialing the portable telephone device having a GPS (Global Positioning System) receiving unit (for example, see Patent Reference 1). Thereby, the searcher can know the position of the mobile phone device carried by the searched person.

[0004]
[Problems to be solved by the invention]
However, the mobile phone device having a GPS (Global Positioning System) receiving unit is not widely used because of a smaller storage capacity and a smaller display area as compared with a vehicle navigation device. Even with the added value of the search function, there was a problem that a large increase in the penetration rate could not be expected.
[0005]
In some cases, the environment of the other party's mobile phone device may not be positional information. For example, there may be a case where the user wants to know whether the room is a construction site, a car or not, a train or not, a meeting or not, and a walking or stationary state.
[0006]
[Means for Solving the Problems]
In view of the above, the portable telephone device of the present invention has a call key and communication means for transmitting and receiving to and from the caller, and operates when the caller receives a call request from the caller. In the mobile phone device which shifts to a call state by being performed,
Registration means for registering a signal, a microphone for detecting a sound, and the microphone, upon receiving a call request from a caller, receiving a signal corresponding to the registered signal before operating the call key. And control means for transmitting the detected sound to the caller.
[0007]
The apparatus further includes a battery remaining amount detecting unit for detecting a battery remaining amount, and transmits the battery remaining amount when transmitting the sound.
[0008]
Further, the apparatus further includes a battery remaining amount detecting unit for detecting a battery remaining amount, and when the battery remaining amount becomes equal to or less than a predetermined value, the control unit transmits to the caller that the battery remaining amount is low.
[0009]

[0010]
In addition, the apparatus further includes a battery remaining amount detecting unit for detecting a battery remaining amount, and the control unit stops the intermittent transmission when the battery remaining amount falls below a predetermined value.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. The mobile telephone devices of the calling party and the called party in the present embodiment are CDMA mobile phones that use a plurality of carriers of the same frequency in the same cell. FIG. 1 is a block diagram showing a configuration of a main part of the embodiment.
[0012]
A communication circuit (1) transmits a signal from a baseband unit (3) described later to a base station via an antenna (2) or receives a radio wave from the base station via an antenna (2). Or
[0013]
(3) is a baseband unit, which has a CDMA processing circuit (31) and an audio codec (32). The CDMA processing circuit (31) performs code division multiple access, scrambling, error control, and timing detection. The audio codec (32) compresses (encodes) and decompresses (decodes) the audio, performs analog-to-digital conversion, and changes the reception volume and microphone sensitivity by an internal amplifier circuit (not shown). .
[0014]
Reference numeral (4) denotes a speaker that is used for a telephone call to the ear, and converts an electric signal of the baseband unit (3) amplified by the amplifier circuit (5) into a voice. (6) is a microphone used for telephone conversation, which converts voice into an electric signal. (7) is an amplifier circuit, which amplifies the output of the microphone (6) and outputs the amplified output to the baseband unit (3).
[0015]
(8) is a loudspeaker for loudspeakers for making the received sound heard by surrounding people. The speaker (8) converts the electric signal of the baseband unit (3) amplified by the amplifier circuit (9) into sound. The speaker (8) also sounds an incoming call notification.
[0016]
A switching circuit (10) turns ON / OFF the connection between each of the three amplifier circuits (5), (7), (9) and the baseband unit (3) under the control of a control circuit (11) described later. Note that these three amplifier circuits (5), (7), and (9) have fixed gains, and cannot change the receiving sound volume and microphone sensitivity. The voice codec (32) of the baseband unit (3) changes the reception volume and microphone sensitivity under the control of the control circuit (11).
[0017]
(11) is a control circuit composed of a microprocessor, which controls each unit based on a ROM (12) storing an operation program. (13) is a RAM for storing information necessary for the operation of the control circuit (11).
[0018]
(14) is a liquid crystal display unit having a backlight (not shown), and displays a telephone number, an image captured by a camera (16) described later, and the like. Numeral (15) is an input means, which is a numeric keypad (151) for inputting a telephone number, a call key (152) for starting a call, an end key (153) for operating a call end, and a signal input / output terminal. It has a registration key (154) for performing a registration operation. (16) is a vibrator, which notifies an incoming call by vibration. (17) is a battery capacity detection circuit for detecting the remaining battery level of a rechargeable dry battery (not shown) for supplying power to the apparatus.
[0019]
A signal for transmitting an image is registered in advance by a user of the present apparatus. When the registration key (154) is pressed, the control circuit (11) causes the RAM (13) to store the characters (eg, "NOISE") input until the registration key (154) is pressed again.
[0020]
FIG. 2 is a flowchart showing the operation of the control circuit (11). The variable A is stored in a register (not shown) of the control circuit (11). When the variable A is 0, it indicates a mode in which sound is not transmitted, and when the variable A is 1, it indicates a mode in which sound is transmitted. The initial variable A is 0 (S1).
[0021]
In a standby state (N of S2 → N of S9 → N of S2), the control circuit (11) receives the caller number when a call request is received from the caller (Y of S2). Then, this is stored in the RAM (13) (S3). Then, when the call key (152) is pressed (Y in S4), a process of talking with the caller is performed (S5).
[0022]
If the call key of the caller's mobile phone device is depressed while the call key (152) of the called party's mobile phone device is not pressed and a call is received, the character input mode is entered, and the character (eg, " NOISE "or" OFF ") is input, and if the call key is pressed again, the input character is transmitted to the called party's mobile phone device.
[0023]
In a state in which the call key (152) of the called party's mobile phone device is not pressed and a call is being received, the control circuit (11) causes the control circuit (11) to match a registered character stored in the RAM (13) (eg, "NOISE") Is received (Y in S6), the variable A is set to 1 and a mode for transmitting sound is set (S7). Then, the sound at that time is detected by the microphone (6), and the detected sound and the remaining battery level detected by the battery capacity detection circuit (19) are transmitted to the portable telephone device of the caller (S8), and step S2 is performed. Return to standby state. The tone continues to be transmitted until the caller stops calling. When transmitting the sound and the remaining battery level, the transmission goes off-hook once, and the transmission goes on-hook when the transmission ends.
[0024]
Further, the registration data may be any data as long as it is to be collated, and is not limited to characters. For example, a signal corresponding to a special key may be used. The registration data may be the telephone number of the caller. At this time, if the caller performs only the calling operation, the portable telephone device of the callee automatically receives the telephone number of the caller and transmits the surrounding sound. That is, the sound is automatically transmitted to the permitted caller number.
[0025]
If the variable A is 1 during standby (Y in S9), it is checked whether a predetermined time has elapsed from the time transmitted in step S8. After moving a predetermined distance, the caller is automatically dialed (S11), the sound is detected by the microphone (6), and the detected sound and the remaining battery level detected by the battery capacity detection circuit (19) are emitted. The call is transmitted to the caller (S12), and the process returns to step S2 to enter a standby state.
[0026]
Although the sound is transmitted every time a predetermined time elapses, the sound may be transmitted intermittently. For example, the sound may be transmitted every time a user travels a predetermined distance with a GPS receiver. Further, the intermittent interval (predetermined time or predetermined distance) may be set by the caller.
[0027]
If the variable A is 1 during standby (Y in S9), it is checked whether the remaining battery level is equal to or less than a predetermined value (for example, 1/5) (S13). When the remaining battery level falls below a predetermined level (Y in S13), the caller is automatically dialed (S14) and a voice message indicating that the remaining battery level is low (for example, "The remaining battery level is less than 1/5" .)) (S15), return the variable A to 0 (S16), return to step S2, and enter the standby state.
[0028]
The method of notifying that the remaining battery level is low is not limited to voice, and display data or data for controlling lighting of the LED may be transmitted.
[0029]
When the control circuit (11) receives “OFF” (Y in S17) in a state of receiving a call while the call key (152) of the called party's mobile phone device is not pressed, the sound is returned by returning the variable A to 0. The mode is set not to transmit (S18).
[0030]
【The invention's effect】
As described above, according to the present invention, the portable telephone device of the called party (searchee) transmits the surrounding sound when the call is received to the portable telephone device of the calling party (searcher). As a result, the calling party can know the environment of the mobile phone of the called party. For example, if you hear the sound of a vehicle or train, you are more likely to be on the vehicle or train, if you hear the sound of walking, you are more likely to be walking, and if you hear the clock sound near the charger, you will be at home. There is a high possibility that you will be in the meeting, if you speak during the meeting, you are likely to be in the seat of the meeting, and if the noise of the downtown area is high, you are likely to be in the downtown area. Further, since the present invention does not use dedicated hardware (for example, a GPS detection circuit for detecting the current position), it can be easily applied to a conventional mobile phone device.
[0031]
As described above, the present invention automatically receives a caller's mobile phone device when a signal corresponding to a character registered in the called party's mobile phone device is received during an incoming call. Transmits the sound around the device.
[0032]
As described above, since the operation of the called party's mobile phone device is the detection of a character being received, the calling party first dials the called party, and when there is no response, the caller continues to be registered. You just need to send the characters you have. As described above, since the calling operation of the caller is continued, the operability is good.
[0033]
In addition, since the sound is transmitted on condition that the registered character matches, the called party can protect his / her private.
[0034]
Further, the present invention automatically dials and transmits a sound every time a predetermined time elapses. For this reason, when the called party is moving, the calling party does not have to repeatedly perform the operation for requesting a sound. In particular, there is a great effect when the calling party is driving to the vehicle and heading for the called party. When the battery level is low, the transmission of the sound is automatically stopped, so that the battery can be prevented from running out.
[0035]
The present invention also transmits the remaining battery level to the caller's mobile phone device together with the sound of the called party's mobile phone device. In addition, when the remaining battery level becomes low, a notification to that effect is made automatically. As a result, the calling party can consider that the battery of the mobile telephone device of the called party has run out.
