The present invention relates to a method for automatically regulating the volume of a ringtone and a communication device using the same method, and more particularly to a method for automatically regulating the volume of a ringtone and a communication device using the same method that compare the sound value of the environment with a predetermined standard value and automatically adjust the volume of the ringtone according to the compared result.
As science and technologies advance, high-precision electronic products are used extensively to improve the quality of our life, and one of the communication devices such as a mobile phone is developed to make our life more convenient. Besides the functions of keeping in touch with friends or relatives at a remote end, sending or receiving short messages, writing E-mails, and maintaining a schedule, mobile phones also can be used for listening to music, playing games, performing calculations and taking pictures. The mobile phones usually come with a small, light and stylish design, so that users can perform the aforementioned operations conveniently.
If a traditional communication device receives an incoming call from another communication device, the following steps will be processed:
(Step 101) An incoming call processing unit produces an interrupt signal which is sent to a control unit in the communication device, such that after the incoming call processing unit in the communication device receives an incoming call, the communication device will enter an incoming call mode;
(Step 102) The control unit obtains a predetermined ringtone from a ringtone database and sends the ringtone to a sound generating element;
(Step 103) The ringtone set with a predetermined volume is played through a sound generating element until the incoming call is picked up by the user of the communication device or the incoming call processing unit no longer receives the incoming call, the procedure ends when the communication device exits the incoming call mode.
In a traditional communication device, the volume of the ringtone played by the communication device is set by the communication device user, so that if the communication device is carried from a quiet environment to a noisy environment, the volume originally set for the quiet environment will be too low for the noisy environment, and users may miss a call. On the other hand, if the communication device is carried from a noisy environment to a quiet environment, the volume originally set for the noisy environment will be too loud for the quiet environment, and thus the user has to frequently set the volume of the communication device with such inconvenient design, or else it may cause inconvenience to the user and nuisance to others. Therefore, finding a way of designing a communication device capable of automatically regulating the volume of a ringtone demands immediate attentions and feasible solutions.
In view of the foregoing shortcomings of the prior art, the inventor of the present invention based on years of experience to conduct extensive researches and experiments and finally developed a communication device for automatically regulating the volume of a ringtone according to the sound value of the environment.
Therefore, it is a primary objective of the present invention to overcome the foregoing shortcomings by providing a method for automatically regulating a ringtone and a communication device using the same method, and a control unit of the communication device installs a regulating program, such that when the communication device receives an incoming call, the control unit detects an external sound signal through a sound detecting unit, and the regulating program compares a corresponding sound value converted from the external sound signal with a predetermined standard value stored in the communication device and automatically regulates the corresponding sound value to a regulation value until the regulation value is greater than the corresponding sound value and then plays the preset ringtone at the volume of the regulation value through a sound generating unit.
To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.

In Step 201, an incoming call processing unit 30 in the communication device 20 generates an interrupt signal and sends the interrupt signal to a control unit 21 in the communication device 20, such that the communication device 20 will enter an incoming call mode.
In Step 202, the control unit 21 obtains an external sound signal detected by a sound detecting unit 40 of the communication device 20 and converts the external sound signal into a corresponding sound value (or noise value).
In Step 203, a regulating program 22 installed in the control unit 21 determines whether or not the corresponding sound value is greater than a reset standard value provided by the regulating program; if yes, then process Step 204, or else process Step 205.
In Step 204, the regulating program 22 automatically adjusts the magnitude of a regulation value provided by the regulating program 22 until the regulation value is greater than the corresponding sound value, and then process Step 207.
In Step 205, the regulating program 22 determines whether or not the corresponding sound value is smaller than a low threshold value provided by the regulating program 22 ; if yes, process Step 206, or else the regulating program 22 automatically regulates the magnitude of the reset regulation value until the regulation value, is greater than the corresponding sound value, and then process Step 207.
In Step 206, the communication device 20 enters a mute mode and turns on an output unit 23 of the communication device 20, so that an output of the output unit 23 can remind the user of the communication device 20 about the current incoming call status, and then process Step 208.
In Step 207, the control unit 21 plays a predetermined ringtone at the volume of the regulation value through a sound generating unit 50, and then process Step 208.
In Step 208, the procedure is ended after the user of the communication device 20 receives an incoming call or the incoming call processing unit 30 no longer receives the incoming call, so as to exit the incoming call mode, and then process Step 202 again.
