[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless device equipped with a device for automatically setting a ringing volume and a listening volume.

[0002]

2. Description of the Related Art FIG. 4 is a block diagram showing a configuration of an example of a conventional radio device. In FIG. 4, 1 is an antenna, 2 is a receiving unit, 3 is a demodulation unit, 4 is a control unit, 5 is a display unit, 7 is a volume setting unit, for example, a switch, 10A is a volume changing unit for changing the volume, and 11 is a resonator. , A speaker, and 12 is a memory for storing the set volume, for example, a ROM. The ringing volume of a conventional portable wireless device with a ringing function, for example, a ringing receiver is set by the user or the operator by operating the switch 7 each time depending on the place to be called and the surrounding conditions. For example, set the volume to a high level in a noisy town so that you can hear the ringing tone, or set it to a low level in quiet places such as during a meeting or at a movie theater to avoid disturbing others. ing.

[0003]

However, in the prior art, since the ringing volume and the listening volume are set by operating the switch 7 or the like, it may be forgotten to set the ringing volume according to the noise level. , In that case, you may make a mistake in setting, and in a quiet place such as a conference room, you accidentally make a loud call to surprise the surroundings, and the voice of the other party in the conversation leaks, causing annoyance and noise. There is a problem that when the user makes a low volume call in a noisy place, the ring tone and the voice of the other party may not be heard. Therefore, it is necessary to reset the volume by yourself each time.

[0004]

The wireless device of the present invention solves the above-mentioned problems of the prior art, and automatically adjusts the ringing volume and the listening volume according to the ambient noise level and the volume set by the user. As shown in FIG. 1, noise in the surrounding environment is detected by the external noise detection unit 8, the volume is set by the volume setting unit 7, and the set volume and the level of the detected external noise are calculated by the volume control unit 6. , Based on the calculation result,
The feature is that the volume is automatically adjusted.

Is an antenna of a radio device with a calling function, 2 is a receiving unit for receiving a radio wave of an information signal including a calling signal, 3 is a demodulating unit for demodulating the signal, 4 is a volume control unit 6 and D / A for the calling signal.
It is a control unit that outputs an information signal to the display device 5 via the converter 10 to the resonator (speaker) 11. 6 is the ringer volume,
A volume control unit for controlling the reception volume, 7 is a volume setting unit, for example, a switch, 8 is an external noise detection unit such as a pickup microphone for detecting external noise, and 9 is A for A / D converting the output of the external noise detection unit 8. A / D converter, 10 is a D / A converter that D / A converts the output of the volume control unit 6 and outputs it to the resonator 11, 11 is a resonator (speaker) for controlling the ringing volume and the listening volume, 12 Is a memory that stores the set volume,
For example, ROM.

In the first embodiment, the external noise is detected by the external noise detector 8 and the detected analog voltage is digitally converted by the A / D converter 9. The detected value and the user set value set by the switch 7 are compared and calculated by the volume control unit 6. Table 1 shows an example of this comparison operation.

[0007]

[Table 1]

The digital value resulting from the operation of the volume control section 6 is converted into an analog value by the D / A converter 10, and the volume of the resonator 11 is controlled by the level of the converted voltage.

FIG. 2 is a block diagram showing the configuration of the second example of the embodiment of the wireless device of the present invention. In the second mode, the output of the external noise detection unit 8 is input to the volume control unit 6 as an analog value as it is, and is compared and calculated with the set value set by the switch 7.
The resulting analog value is used as a volume variable unit 10A such as a variable resistor.
1 to control the volume of the resonator 11 by changing
It has the same configuration as.

Next, the volume adjustment of the radio device of the present invention will be described. FIG. 3 is a flowchart for digitally controlling the volume in the present invention. The radio wave of the information signal including the calling signal is received by the receiving unit 2 via the antenna 1, and the external noise in the surroundings is detected by the external noise detecting unit 8. Substituting the sampling number n of ambient noise (external noise) into N, substituting into A (n), subtracting one from N, and the result being 0, the ambient noise n times The average value of the sampling values is calculated and used as the current noise. The loudness of the ringing tone is determined according to the table in Table 1.

[0011]

As is apparent from the above description, according to the present invention, the ringing volume and the receiving sound can be automatically adjusted according to the external noise level and the volume set by the user. for that reason, . Depending on the volume settings of the ringing tone and the receiving tone, the user may find that the ringing tone and the receiving tone become loud in noisy places.
Since the ringing volume and the receiving volume are low in a quiet place, there is no fear that the ringing tone or the receiving volume will not be heard, or that the ringing volume or the receiving volume will be too loud to bother others. . No more forgetting to set ringing tone and receiving tone. . It is not necessary to set the ringing volume and the listening volume according to the noise environment each time. . Once the user (user) makes the setting once at first, there is no need to perform various operations thereafter.
