Abstract

본 발명은 이동 무선전화기의 사용시 마이크로 입력되는 사용자의 송신음의 레벨에 따라 스피커로 입력되는 수신음의 레벨을 조정하는 마이크 입력레벨에 따른 자동 수신레벨 조정장치 및 방법에 관한 것으로, 일반 이동 무선전화기로 공공장소에서 통화중 상대방의 목소리가 너무 작아서 목소리를 크게 하여 주위 사람들에게 피해를 주게 되거나, 음량 조절키를 조절해가면서 통화를 해야하는 문제점이 발생하게 되는데, 본 발명에서는 상기와 같은 문제점중 수신음이 잘 들리지 않아 사용자의 목소리가 커지는 것을 이용하여 통화시 마이크의 입력레벨을 측정함으로써 스피커의 출력레벨이 자동 조정되도록 하며 볼륨을 조정하면서 통화를 해야 하는 번거러움이 줄어들게 된다.The present invention relates to an automatic reception level adjusting device and method according to the microphone input level for adjusting the level of the reception sound input to the speaker according to the level of the user's transmission sound input to the microphone when using the mobile radio telephone, In a public place, the other party's voice is too small to make the voice louder, causing damage to the surrounding people, or adjusting the volume control key, which causes a problem of having to make a call. By using the loud voice of the user who cannot hear the voice, the input level of the microphone is measured during the call so that the output level of the speaker is automatically adjusted, and the trouble of having to talk while adjusting the volume is reduced.

제2도는 본 발명 마이크 입력레벨에 따른 자동 수신레벨 조정장치의 구성 블럭도.2 is a block diagram of the automatic reception level control apparatus according to the microphone input level of the present invention.

Claims

In a mobile radiotelephone comprising a key for adjusting the volume of a received sound, a level director 20 for detecting an input level of a signal through a microphone 13 for converting a voice signal into an electrical signal; A memory unit 30 for storing a reference level of a reception sound suitable for a user to listen to; And a microprocessor 40 for adjusting the volume of the speaker 12 by comparing the input level detected by the level detector 20 with a reference level stored in the memory unit 30. Automatic reception level control device according to microphone input level.

A method for automatically adjusting a speaker and a volume level according to a microphone input level, comprising: a first step of detecting an input level by an electrical signal of a voice signal input through a microphone when the mobile wireless telephone is in a call mode; A second step of comparing the magnitude of the preset reference level with the input level detected in the first step; A third step of increasing the speaker volume to a reference level if the input level is less than the reference level in the second step, and comparing the magnitude of the current input level with the previous input level if the input level is larger; A fourth step of increasing the speaker volume to the previous level if the current input level is less than the previous input level in the third step, and decreasing the speaker volume to the previous input level if the current input level is larger; And a fifth step of repeatedly checking the call mode state even after the second to fourth steps and repeating the steps.
