Abstract

PURPOSE: To adjust a tone volume automatically without giving trouble onto surrounding persons by converting external noise into a DC by a tone volume setting control section and varying a tone volume variable section of a resonator based on the DC level thereby controlling a call tone volume. CONSTITUTION: This device is provided with an antenna 5 for calling receiver, a reception section 6 receiving a radio wave of an information signal including a call signal, a demodulation section 7 demodulating the signal and a control section 8 outputting a call signal to a resonator 4 and an information to a display device 9, and also with an external noise detection section 1 such as a pickup microphone detecting external noise, a tone volume setting control section 2 amplifying the detected external noise, rectifying it into a DC signal, a sound volume variable section 3 such as an attenuator varying the DC level, the resonator 4 and a switch 10. When the detection section 1 detects external noise for a boundary of the use of the receiver, the tone volume setting section 2 converts the noise into a DC signal and the tone volume variable section 3 of the resonator 4 is varied by the DC level and the call tone volume is automatically controlled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically setting a ringing volume of a portable device having a calling function.

[0002]

2. Description of the Related Art The ringing volume of a conventional portable device with a calling function, for example, a calling receiver is set by a user or an operator each time according to a place to be called or a surrounding condition. 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 is set by operating the switch, forgetting to set the ringing volume according to the noise level or making a setting error. In that case, there is a problem that the ringer cannot hear the ringing sound, and the loud ringing in a quiet place is surprising and annoying.

[0004]

In order to solve the above-mentioned problems, the apparatus of the present invention detects external noise by the external noise detecting section 1 and converts this detected external noise into direct current by the volume setting control section 2. The ringing volume is controlled by varying the volume varying unit 3 of the resonator 4 according to the DC level.

[0005]

[Operation] With such a configuration, external noise is detected by the external noise detection unit 1, the detected external noise is converted into direct current by the volume setting control unit 2, and the direct current level of the resonator 4 The volume varying unit 3 is varied to control the ringing volume.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the configuration of an embodiment of the device of the present invention. First, the configuration of this embodiment will be described. In FIG. 1, 5 is an antenna of the receiver for calling, 6 is a receiving unit for receiving the radio wave of the information signal including the calling signal, 7 is a demodulating unit for demodulating the signal, 8 is a resonator (speaker) 4 for the calling signal, The control unit outputs an information signal to the display 9. Reference numeral 1 is an external noise detection section such as a pickup microphone that detects external noise, 2 is a volume setting control section that amplifies the detected external noise, rectifies it and converts it into direct current, and 3 is an attenuator that is variable according to the direct current level Volume control part, 4
Is a resonator (speaker) whose ringing volume is controlled by the volume varying unit 3, and 10 is a switch for canceling the volume setting.

Next, the operation of this embodiment will be described. External noise of the environment in which the receiver for calling is used is detected by the external noise detection unit 1, and the detected external noise is converted into direct current by the volume setting control unit 2, and the volume of the resonator 4 is changed by the direct current level. The variable unit 3 is changed to control the ringing volume. That is, the ringing volume can be automatically set according to the external noise level.

[0008]

As described above, according to the present invention, the ringing volume can be automatically set according to the external noise level. Therefore, the user does not have to set the volume of the ringing tone, and the ringing tone becomes loud in a noisy place,
Since the ringing tone becomes small in a quiet place, there is no fear that the ringing tone cannot be heard or the ringing tone is too loud to bother others. Never forget to set the ring volume. It is not necessary to set the ringing volume according to the environmental noise each time. There is no need for the user (user) to perform various operations.
