Abstract

PROBLEM TO BE SOLVED: To permit a subscriber to grasp the largeness of his own voice while making a call and to prevent him from bothering the neighboring people by alarming the subscriber that a detected signal level exceeds a voice signal reference value when it exceeds. SOLUTION: The voice of a speaker or a circumferential sound which is collected is converted into an electric signal level in an electroacoustic converter device 1 and the signal is amplified to a certain level by an amplifier 2. Communication by the amplified signal level is executed by a transmitting and receiving circuit part 3 in a radio wave. During the operation, a sound signal level is taken-out by a voice signal detecting means 4 for detecting an electric level and the voice signal level detected through the use of the voice signal reference value 5 is compared with the voice signal reference value by a comparing means 6. When the detected voice signal level is judged to be the one exceeding the voice signal reference value by comparison, alarm display is executed to the subscriber of a portable radio terminal equipment by a means 7 vibrating the case body.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a portable radio terminal. More specifically, the present invention relates to a warning method for warning a subscriber of a portable wireless terminal of an increase in voice volume.

[0002]

2. Description of the Related Art A conventional portable radio terminal capable of adjusting a voice volume has a configuration in which a volume switch is manually operated to switch a transmission or reception volume to a volume divided into several stages. Further, there is also a configuration in which a received signal and a signal obtained by converting a sound around the handset are judged by a judging means, and the volume of the sound received from the handset is automatically adjusted based on the result.

[0003]

However, the above-mentioned configuration for automatically adjusting the receiving volume from the handset can be adjusted to an appropriate volume, but the volume of the other party on the receiving side is average. The volume is adjusted to an appropriate level, and nothing changes on the sending side. In other words, if the sending person is talking loudly, the person does not notice that he is talking loudly, and the receiving side is adjusted to an appropriate volume and Without being noticed, no one can pay attention and keep talking in a loud voice.

[0004]

Therefore, in order to solve the above-mentioned problems, a portable radio terminal according to the present invention comprises a voice signal for detecting an electric signal level of a speaker's voice or ambient sound taken from a microphone. In a portable wireless terminal having detection means and comparison means for comparing the detected signal level with a preset audio signal reference value, when the detected signal level exceeds the audio signal reference value, Warning means for giving a warning to the user to that effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an operation state of an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an acoustoelectric conversion device (microphone), 2 denotes an amplifier (microphone amplifier), 3 denotes a transmission / reception circuit unit, 4 denotes an audio signal detecting means (usually an A / D converter) for detecting an electric level of sound, 5 is a means for holding the audio signal reference value, 6 is a comparison means for comparing the detected audio signal with the audio signal reference value, and 7 is a means (usually a motor) for vibrating the housing based on the result of the comparison means 6. Show.

Here, a flow of a series of operations of the present invention will be described with reference to FIG. First, the sound of a speaker or surrounding sounds collected by the acoustoelectric conversion device 1 is converted into an electric signal level, and the amplifier 2 amplifies this signal level to a certain level. The amplified signal level is communicated by the transmission / reception circuit unit 3 via radio. In the operation, the audio signal level is extracted by the audio signal detecting means 4 for detecting the electric level, and the audio signal level detected using the held audio signal reference value 5 and the audio signal reference value are compared by the comparing means 6. Compare. If it is determined from the comparison result that the detected audio signal level exceeds the audio signal reference value, a warning is displayed to the subscriber of the portable wireless terminal by means of vibrating the housing.

Next, the situation including the above case will be described with reference to the flowchart of FIG. In addition, 101 to 104 in the figure indicate each step.

This flowchart starts from the point where the acoustoelectric conversion device captures the speaker's voice or surrounding sounds during a call. In this state, it is detected as the signal level of the voice of the speaker or the surrounding sound taken in from the acoustoelectric conversion device (101). The signal level of the fetched sound is compared with a preset audio signal reference value (10
2) If the signal level of the captured sound exceeds the audio signal reference value (103), a warning is displayed to notify the subscriber of the portable wireless terminal (104). However, if the received signal does not exceed the audio signal reference value, the process returns to step 101 of the flowchart and repeats this series of operations until the call ends. Step 104
In step 10 of this flowchart, the subscriber is warned to that effect in step 10 without any operation by the subscriber.
It returns to 1 and performs a series of operations during a call. This warning display is stopped when the subscriber stops the operation by some operation or when it is determined by the further detection comparison that the signal is below the audio signal reference value.

[0010] The audio signal reference value may be set in the portable radio terminal in advance, or may be set as desired by the subscriber.

As described in detail above, the present invention comprises display means for displaying to the subscriber when the detected signal level compared by the comparing means exceeds the audio signal reference value. Therefore, the subscriber of the portable wireless terminal can grasp the loudness of his own voice while talking.

[0012]

As described above, according to the present invention, the subscriber of the portable radio terminal can grasp the loudness of his / her own voice while making a call, and the subscriber can immediately take an appropriate measure. The warning is given in the same way even if the voice becomes loud again, so that it is possible to prevent the trouble of surroundings while always paying attention to the volume of the conversation. In addition, if the audio signal reference value is set to a desired level, a reference value that is comfortable for all subscribers can be selected. Therefore, there is an effect that the basic manner can be notified to the subscriber with a simple configuration.
