Typically, the body 102 may include a display module, a keyboard module, a sound receiver module or a sound-broadcasting module, for example. The mobile phone 100 has a lengthwise axis 118, wherein the lengthwise axis 118 vertically extends in a lengthwise direction of the body 102 of the mobile phone 100.
In one embodiment, the control unit 102 may include a incoming call alert control module 108. The incoming call alert control module 108 is usually preset with a plurality of incoming call alert modes, including an outdoor ringing alert mode, an indoor ringing alert mode, a vibration alert mode, a silent alert mode, a flashing alert mode, an indoor ringing and vibration alert mode and an outdoor ringing and vibration alert mode, for example. The mobile phone 100 can enter one of the incoming call alert modes by operating the incoming call alert control module 108. Typically, the main difference between the outdoor ringing alert mode and the indoor ringing alert mode is that the telephone ring of the outdoor ringing alert mode is much louder than that of the indoor ringing alert mode. In addition, both the indoor ringing and vibration alert mode and the outdoor ringing and vibration alert mode in these incoming call alert modes represent the fact that when a incoming call signal is transmitted to the mobile phone 100, the mobile phone sends out the incoming call alert including ringing and vibrating, wherein the ring of the outdoor ringing and vibration alert mode is much louder than that of the indoor ringing and vibration alert mode similarly. In one exemplary embodiment, the control unit 104 may be a central processing unit (CPU), for example.
The receiver 106 may be disposed in the body 102 of the mobile phone 100, or a portion of the receiver 106 may be disposed in the body 102 and the other portion of the receiver 106 may protrude on the outer side of the body 102. In one embodiment, the receiver 106 may be an antenna, for example. The receiver 106 is electrically connected to the control unit 104 in the body 102 via a wire 112. The receiver 106 can receive an incoming call signal and can transmit the received incoming call signal to the control unit 104 through the wire 112.
The sensor 110 is similarly disposed in the body 102 of the mobile phone 100, wherein the sensor 110 may be electrically connected to the control unit 104 through at least one wire, such as wires 114 and 116. In one embodiment, the sensor 110 may be, for example, a gravity sensor or a motion sensor. Simultaneously refer to FIG. 2A. FIG. 2A is a schematic diagram showing a mobile phone oriented in one direction in accordance with a preferred embodiment of the present invention. The sensor 110 can sense an included angle θ between the lengthwise axis 118 of the mobile phone 100 and a level 122. In the embodiment illustrated in FIG. 2A, the mobile phone 100 is put on a desk 120 in a vertical position state while the desk 120 is put on the level 122, so that the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 is substantially 90 degrees, and the orientation of the mobile phone 100 is oriented in a vertical direction. Refer to FIG. 2B. FIG. 2B is a schematic diagram showing a mobile phone oriented in another direction in accordance with a preferred embodiment of the present invention. In the embodiment illustrated in FIG. 2B, the mobile phone 100 is put on the desk 120 in a horizontal position state while the desk 120 is put on the level 122, so that the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 is substantially 0 degree, and the orientation of the mobile phone 100 is oriented in a horizontal direction.
Refer to FIG. 1 again. In the present exemplary embodiment, the sensor 110 is typically in a disable state. When the control unit 104 receives the incoming call signal transmitted by the receiver 106 through the wire 112, the control unit 104 can activate the sensor 110 through the wire 114. Then, the sensor 110 is in an enable state and transmits a sensed signal comprising the data of the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 to the control unit 104 through the wire 116.
In the present exemplary embodiment, the user can set the incoming call alert mode corresponding to the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 sensed by the sensor 110 according to the personal need. In one exemplary embodiment, when the detected included angle θ between the lengthwise axis 118 and the level 122 is substantially 0 degrees, the mobile phone 100 is oriented in a horizontal direction. Now, if the mobile phone 100 oriented in the horizontal direction is located indoors, and the incoming call alert cannot be conspicuous. Therefore, the incoming call alert mode of the mobile phone 100 in this orientation may be preset as the quieter alert mode, such as the vibration alert mode, the flashing alert mode, the indoor ringing alert mode and the indoor ringing and vibration alert mode by operating the incoming call alert control module 108 in the control unit 104. When the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 is substantially 90 degrees, the mobile phone 100 is oriented in a vertical direction. Now, if the mobile phone 100 oriented in the vertical direction is disposed in a pocket or a bag of the user, and the user is in motion and may be in the outdoors, the incoming call alert needs to attract the user's attention. Therefore, the incoming call alert mode of the mobile phone 100 in this orientation may be correspondingly preset as the alert mode, which is easier to attract the user's attention, such as the outdoor ringing alert mode and the outdoor, ringing and vibration alert mode by operating the incoming call alert control module 108 in the control unit 104.
Simultaneously refer to FIG. 3 and FIG. 1.

Next, referring to FIGS. 2A and 2B simultaneously, such as illustrated in step 206, the activated sensor 110 in the mobile phone 100 senses the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122. Further, step 206 further includes transmitting the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 sensed by the sensor 110 to the control unit 104 through the wire 116.
Then, such as illustrated in step 208, the control unit 104 can determine the orientation of the mobile phone 100 according to the included angle θ. The orientation of the mobile phone 100 includes various orientations, which are preset in the product or which are set by the user in the control unit 104, such as oriented in the vertical direction as shown in FIG. 2A or oriented in the horizontal direction as shown in FIG. 2B.
Presently, the incoming call alert modes corresponding to the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 are preset in the production of the mobile phone 100 or are set by the user according to the personal need. Therefore, such as illustrated in step 210, the incoming call alert control module 108 in the control unit 104 of the mobile phone 100 enters one of the incoming call alert modes according to the a determination of the orientation of the mobile phone 100 obtained in the determination step 208.
For example, such as shown in FIG. 2A, when the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 is substantially 90 degrees, the determination is that the mobile phone 100 is oriented in a vertical direction, and the mobile phone 100 enters one alert mode of the incoming call alert modes, which can attract the user's attention, such as the outdoor ringing alert mode or the outdoor ringing and vibration alert mode. In another embodiment, referring to FIG. 2B, when the included angle θ between the lengthwise axis 118 of the mobile phone 100 and the level 122 is substantially 0 degree, the determination is that the mobile phone is oriented in a horizontal direction, and the mobile phone 100 enters one inconspicuous alert mode of the incoming call alert modes, such as the vibration alert mode, the indoor ringing alert mode, the flashing alert mode and the indoor ringing and vibration alert mode.
According to the aforementioned embodiments, one advantage of the present invention is that a mobile phone is equipped with a sensor The sensor can sense an included angle between a lengthwise axis of the mobile phone and a level, so that a control unit of the mobile phone can automatically enter one of the incoming call alert modes according to the detected included angle.
