L Wu Ke technology has been used in the past, but because of the wide range of designers that carry equipment; the more features that are lacking, the most common is the same sound playback system, so there is a high 'and thus damage the startup size, if the sound will be set it is possible To listeners to communication skills. Therefore, the media is also a sound device and may hurt the hearing. The sound broadcast is played by high-pitched sound, which is caused by the high performance of the mobile phone. The physical function will be derived from the playback device. The requirements are only for the good and rapid development of call quality. The mobile phone has become a requirement of modern people for its convenience and diversification, so it has been added to the mobile phone equipment. In contrast, many components have compatibility problems. Which is related to the volume adjustment of the talker, one of the audio control functions are controlled by the same IC, the volume is suddenly raised due to the wrong touch of the button, the system volume setting will record its volume set at high volume, and subsequent calls If the user fails to adjust the volume in real time, Muyu has a mobile phone (Nokia 76 50) using a sensor to measure the distance between the human ear and the mobile phone, and then adjust the volume to avoid hearing damage. The in-depth study of this case is obviously different from the technical methods used in Nokia 750a, as the Nokia 76 50 also measures the distance through a sensor.
Nokia7650内建有兩個speaker，因此其針對音量的調整部 分僅是作speaker間的切換（將播放音樂轉換成The Nokia 7650 has two speakers built in, so its volume adjustment part is only for switching between speakers (converting the playback music to

Description of the invention (2) s p a a k e r) of the call, but it is not possible to adjust the detailed volume according to the change of distance. Therefore, this case is not only different in technical means than Nokia 7 650, but also more effective. In addition, this case provides multiple implementation types, which are more diversified and practical in operation. [Summary of the Invention] The main purpose of the present invention is to detect the distance between the surface of an object and the speaker by a sensor, so as to limit the volume of the volume increase / decrease to a safe range acceptable for hearing. In addition, the distance between the surface of the object and the speaker can be measured by the sensor, so as to increase the ringtone of the incoming call / text message. It does not need to perform additional switching / setting of the volume to achieve the purpose of controlling the volume. To achieve the above and other objectives, the present invention provides a distance sensing system for a mobile communication device, including: a sensor that senses a distance from the surface of an object and outputs a value after processing; a comparator The system is electrically connected to the sensor and has a first reference value and a second reference value, which are respectively compared with the value according to the use status of the device, and output a first warning signal when in a call, and when in standby Output a second warning signal; a volume controller electrically connected to the comparator to change the call volume in response to the first warning signal; and a music player electrically connected to the comparator to respond to the second The alert signal changes the volume of the message. Another main object of the present invention is to provide a distance sensing method for a mobile communication device, including the following steps: sensing the distance from a surface of an object

Description of the invention (7) Range (such as step 3 1 6). For example, if the distance is 1 cm, set the volume range to 0 ~ 3 (when the maximum volume is 10). Therefore, the volume controller (3) maximum volume Can only be adjusted to 3. This will prevent you from raising the volume due to careless operation. In addition, the timer (5) will periodically send a trigger signal (such as step 3 1 7) to cause the sensor (1) to perform a sensing action. When the sensor (1) detects again with the surface and After the distance (such as step 3 1 8), a second value will be obtained through the operation (such as step 3 1 9), and the second value will be compared with the reference value (such as step 20). If the second value> reference value , The volume range will be limited to the first volume range (such as step 314); conversely, if the second value <reference value, the volume range will be limited to the second volume range (such as step 3 1 5), where the first One volume range > = second volume range. In summary, the distance sensing system and application method of the mobile communication device provided in the above preferred embodiments in this case can improve that the mobile communication device cannot automatically determine the distance between the user and the communicator in the conventional technology. By controlling the volume, the problem that the user misadjusts the volume up / down can be caused, so that the mobile communication device can be more user-friendly and more in line with safety requirements. Therefore, the invention has the value of industrial development. This case can be modified by anyone who is familiar with the art, but it is not as good as the protection of the scope of the application.
