Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile phone device that can be carried outdoors.

With the advancement of communication technology, mobile phone devices that use radio waves and can be used outdoors have been developed.

By the way, such mobile phone devices are usually carried and used outdoors, but they are not always in use (although they are turned on to detect incoming calls).
, is not used except when making a call or receiving a call. That is, although it is always carried around, it has the disadvantage that it is rarely used.

In view of the above circumstances, it is an object of the present invention to provide a mobile phone device that naturally has a mobile phone function, but can also be used as a cassette tape recorder or a radio if necessary, and can be used more frequently.

In order to solve the above-mentioned problem, the mobile phone device according to the present invention is characterized in that it integrally includes a cassette tape recorder section and/or a radio section.

According to the above configuration, when a call is received or when making a call, the original functions of the mobile phone device are utilized, and when the phone is not in use, it can be used as a cassette tape recorder or radio if desired. Can be used. In addition, the speaker or microphone required for a cassette tape recorder, or the speaker required for a radio, can be shared with the mobile phone device, so the complexity of the structure and increase in weight of the mobile power supply device can be minimized. That will happen.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram showing a schematic circuit configuration of a mobile phone device according to the present invention, and FIG. 2 is a perspective view showing its appearance. In these figures, 1 is a control unit, 2 is a radio unit, 3 is a microphone, 4 is a speaker, 5 is a radio unit, 6 is a cassette tape recorder unit, 7 is an antenna, 8 is a telephone operation unit, and 9 is a cassette operation unit. part, 10 is a radio operation part, 1
1 is the cassette lid, 12 is the headphone speaker jack,
13 is a microphone jack, and 20 is a headphone jack.

To explain the circuit configuration of such a mobile phone device along with its operation, first of all, in the telephone function of this mobile phone device, when this device becomes the receiving side, a signal radio wave corresponding to the phone number is transmitted from the nearest relay station of NTT. Then, the antenna 7 captures this and outputs it to the radio section 2. Radio section 2
demodulates the captured radio wave signal and provides it to the control section 1. The telephone control unit 3 determines whether the number obtained by demodulation is its own telephone number or not, and if it is its own telephone number, it determines that it has received a call and, for example, uses the speaker 4 to ring the telephone. generate sound. The user learns of the call by the ringing and operates the hook switch 8a to go into the off-hook state. If the radio or cassette tape recorder is operating, it is stopped and the user becomes ready to talk (off-hook state). Thereafter, the audio signal from the other party is demodulated by the wireless unit 2 and sent via the control unit 2 to the speaker 4 or to the headphone speaker 20 if the headphone speaker 20 is connected to the headphone jack 12. is output, and the audio is output. Of course, the user's voice is converted into an audio signal by the microphone 3, modulated by the wireless unit 2 via the control unit 1, and transmitted wirelessly to the NTT relay station by the antenna 7.

In addition, when the user is on the sending side, when the user operates the hook switch 8a and further operates the numeric keypad on the operation section 5 to enter the telephone number of the other party, the telephone control section 3 that receives this input A dial call is made, and this call signal is modulated by the radio unit 6 and sent to the NT via the antenna 7.
It is sent to the relay station of T. NTT's relay station responds to the received phone number and, if it is the phone number of a mobile phone device, sends out a signal radio wave corresponding to the phone number to call the other party, and also if the received phone number is a phone number of a wired phone device. If it is a number, a call is made to the telephone device of the telephone number through the telephone line.

On the other hand, the radio section 5 is similar to a normal radio, and includes a frequency setting section, a detection section, an amplification section, etc., and can be operated by a radio operation section 10.

Furthermore, sound can be emitted from the speaker 4 or the headphone speaker 20. The cassette tape recorder section 6 is also similar to a normal cassette tape recorder, and has a tape drive section, a magnetic head, etc.
It can be operated using a cassette operating section 9.

Further, sound is emitted through the speaker 4 or the headphone speaker 20, external sound is input through the microphone 3, and the voice of the other party during a telephone call or the voice from the radio is input through the microphone. 3.It is designed to be recorded directly without going through 3.

FIG. 3(a) is a flowchart showing the operation of the mobile phone device when receiving a call. First, it is determined whether or not there is an incoming call (S1). If there is no incoming call, proceed to step 1 and continue to determine the incoming call. If there is an incoming call, it is determined whether the cassette tape recorder or radio is operating. (S2).

If the cassette tape recorder or radio is not operating, a ringing operation is started (S3), and then it is determined whether the hook switch 8a has been pressed (S4). If the hook switch 8a is not pressed (on-hook state),
Proceeding to step 4, the off-footer determination is continued, while if the hook switch 8a is pressed and the off-footer has occurred, the ringing operation is stopped (S5) and the process moves to call processing (S6).

On the other hand, if the cassette tape recorder or radio is operating, processing is performed to reduce the volume (S7).
Thereafter, a ringing operation is performed (S8), and then it is determined whether the hook switch 8a has been pressed (S9).

If the hook switch 8a is not pressed (on-footer state), it is necessary to determine whether the other party has stopped calling 514.
), if the call has not stopped, it is determined to be off-hook (
While continuing S9), if the call has been stopped, the ringing operation is stopped (515), and the volume restoration process is performed (S13).
), return.

On the other hand, if the hook switch 8a is pressed and goes off-hook, the ringing operation should be stopped (5lO), and the cassette tape recorder or radio should also be stopped (5lO).
ll), and then moves to call processing (S12). Then, when the call ends, perform volume recovery processing (313).
, return.

FIG. 4B is a flowchart showing the processing at the time of making a call. First, it is determined whether the hook switch 8a is pressed (321), and if it is not pressed, step 2
1 to continue off-hook determination, and if pressed, it is determined whether the cassette tape recorder or radio is operating (S22).

If the cassette tape recorder or radio is operating, it is automatically stopped (S23), and then step 2
Move to 4.

On the other hand, if the cassette tape recorder or radio is not operating, the process immediately moves to step 24.

In step 24, reception of input of a telephone number using the numeric keypad is started, and a dial call is made using the telephone number input by the operator. Next, a call process is performed (S25), and then the process returns.

According to the above configuration, when receiving or making a call, the original functions of the mobile phone device are utilized, and furthermore, when the phone is not in use, it can be used as a cassette tape recorder or radio, so when the phone is not in use, it can be used as a cassette tape recorder or radio. The mobile phone device can also be used in In addition, the speaker or microphone required for a cassette tape recorder, or the speaker required for a radio, can be shared with the mobile phone device, so that the structural complexity and weight increase of the mobile phone device can be reduced as much as possible. I can do it.

Also, when making a call, your voice is transmitted through the microphone 3.
It is configured so that the voice of the other party can be recorded directly onto the cassette tape without going through the microphone 3, and since it is possible to take notes by voice, the user does not have to take notes with a writing instrument, and it is possible to make phone calls while walking. It becomes possible to reliably retain important contents.

Furthermore, in this embodiment, when a call arrives while the cassette tape recorder or radio is in operation, the sound of the radio, etc. emitted from the speaker 4 is reduced and the bell is rung, so that the user can be sure that the call will not be received. You can know. Note that when using the phone speaker 20,
This headphone speaker 20 emits a bell sound. When emitting a bell sound using the headphone speaker 20,
Since this bell sound does not easily leak to the surroundings, it is a countermeasure against noise in the surroundings.

Furthermore, since the cassette tape recorder or radio is configured to automatically stop operating when the device goes off-hook, the telephone switching operation is extremely simple.

According to the above-described invention, it can be used not only as a telephone, but also as a cassette tape recorder and/or radio, which eliminates the drawbacks of the conventional method, such as carrying a mobile phone at all times (though it is rarely used). It has the effect of being able to do it.
