Method and System for Adjusting Volume

The invention relates to a volume adjustment method and system, in particular to a volume adjustment method and system of a handheld electronic device.

When users use handheld electronic devices, such as mobile phones, MP3s, and PDAs, to make calls or play video and audio, they often encounter situations where the volume needs to be adjusted. Generally, the user adjusts the volume by using the built-in volume adjustment function of the operating system of the handheld electronic device, and the operation process of this adjustment method is relatively complicated. In addition, some handheld electronic devices are provided with a physical key for adjusting the volume, but the provision of such a physical key will make the hardware structure of the handheld electronic device more complicated and higher production costs.

In view of the above, it is necessary to provide a volume adjustment method and system, which can adjust the volume of a handheld electronic device through simple operations, and does not require a special physical key to adjust the volume.

A volume adjustment method includes the following steps: a detection step: when an application program that needs to output sound in a handheld electronic device is activated, continuously detect the angular velocity of the handheld electronic device's rotation through an angular velocity sensor in the handheld electronic device. Including the speed and direction of rotation of the handheld electronic device; and an adjustment step: adjusting the volume of the handheld electronic device according to the speed and direction of rotation of the handheld electronic device.

A volume adjustment system includes a detection module, which is used to continuously detect the angular velocity of the rotation of the handheld electronic device through an angular velocity sensor in the handheld electronic device when the application program that needs to output sound in the handheld electronic device is started. The angular velocity includes the rotation rate and direction of the handheld electronic device; and an adjustment module for adjusting the volume of the handheld electronic device according to the rotation rate and direction of the handheld electronic device.

Compared with the prior art, the volume adjustment method and system of the present invention can adjust the volume of the handheld electronic device through simple operations, and there is no need to specifically set a physical key to adjust the volume.

Refer to FIG. 1, which is a diagram of the operating environment of the preferred embodiment of the volume adjustment system of the present invention. In this embodiment, the volume adjustment system 10 runs in a handheld electronic device 1, and the handheld electronic device 1 further includes an angular velocity sensor 11. The angular velocity sensor 11 is used to detect the angular velocity of the rotation of the handheld electronic device 1, and the angular velocity of rotation includes the speed (speed) and direction of the rotation. The handheld electronic device 1 may be a portable electronic device such as a mobile phone, MP3, PDA, etc.

In addition, a number of application programs are installed in the handheld electronic device 1, and the application programs will output sound after being activated. For example, the application can be a video player, game, etc. If the handheld electronic device 1 is a mobile phone, the application program can also be a call program. The volume adjustment system 10 is used to adjust the volume of the handheld electronic device 1 according to the angular velocity of the handheld electronic device 1 detected by the angular velocity sensor 11 after the application is started.

The volume adjustment system 10 includes an execution module 101, a detection module 102 and an adjustment module 103. The module referred to in the present invention is a computer program segment that completes a specific function, and is more suitable for describing the execution process of software in the handheld electronic device 1 than a program. Therefore, in the present invention, all software descriptions below are described as modules.

The execution module 101 is used for turning on the angular velocity sensor 11 when the application program that needs to output sound in the handheld electronic device 1 is started. After the angular velocity sensor 11 is activated, it will continue to detect the angular velocity of the rotation of the handheld electronic device 1.

The detection module 102 is used to continuously detect the angular velocity of the rotation of the handheld electronic device 1 through the angular velocity sensor 11.

The adjustment module 103 is used to adjust the volume of the handheld electronic device 1 according to the detected angular velocity of the handheld electronic device 1 rotation, that is, the speed and direction of the handheld electronic device 1 rotation.

In this embodiment, when the rate at which the handheld electronic device 1 rotates in a preset direction reaches a preset rate threshold, the adjustment module 103 will amplify the volume of the handheld electronic device 1 in a preset adjustment unit. When the rate of rotation of the handheld electronic device 1 in the opposite direction to the preset direction reaches the preset rate threshold, the adjustment module 103 will reduce the volume of the handheld electronic device 1 in the preset adjustment unit.

For example, the preset direction is a clockwise direction on the plane where the screen of the handheld electronic device 1 is located, the preset rate threshold is 150 degrees per second, and the preset adjustment unit is 10% of the highest volume of the handheld electronic device 1. %. When the hand-held electronic device 1 rotates clockwise on the plane where the screen is located at a rate of 150 degrees/second, the adjustment module 103 amplifies the volume of the hand-held electronic device 1 by 10% of the highest volume. When the hand-held electronic device 1 rotates counterclockwise on the plane of the screen at a rate of 150 degrees/second, the adjustment module 103 reduces the volume of the hand-held electronic device 1 by 10% of the highest volume.

In addition, in other embodiments, the preset rate threshold may also be multiple, and each rate threshold corresponds to a preset adjustment unit. When the rate at which the handheld electronic device 1 rotates in the preset direction reaches one of the rate thresholds, the adjustment module 103 will amplify the volume of the handheld electronic device 1 in an adjustment unit corresponding to the rate threshold. When the rate at which the handheld electronic device 1 rotates in the opposite direction to the preset direction reaches one of the rate thresholds, the adjustment module 103 will reduce the volume of the handheld electronic device 1 in an adjustment unit corresponding to the rate threshold.

For example, the preset direction is a clockwise direction on the plane where the screen of the handheld electronic device 1 is located, there are two preset rate thresholds, the first rate threshold is 100 degrees/sec, and the second rate threshold is 150 degrees/sec. The adjustment unit corresponding to the first rate threshold is 5% of the highest volume of the handheld electronic device 1, and the adjustment unit corresponding to the second rate threshold is 10% of the highest volume. When the hand-held electronic device 1 rotates clockwise on the plane where the screen is located at a rate of 100 degrees/second, the adjustment module 103 amplifies the volume of the hand-held electronic device 1 by 5% of the highest volume. When the hand-held electronic device 1 rotates clockwise on the plane where the screen is located at a rate of 150 degrees/second, the adjustment module 103 amplifies the volume of the hand-held electronic device 1 by 10% of the highest volume.

The execution module 101 is also used to turn off the angular velocity sensor 11 when the application program that needs to output sound is closed.

Refer to FIG. 2, which is a flowchart of a preferred embodiment of the volume adjustment method of the present invention.

In step S1, when the application program that needs to output sound in the handheld electronic device 1 is started, the execution module 101 turns on the angular velocity sensor 11. After the angular velocity sensor 11 is activated, it will continue to detect the angular velocity of the rotation of the handheld electronic device 1.

In step S2, the detection module 102 continuously detects the angular velocity of the rotation of the handheld electronic device 1 through the angular velocity sensor 11, and the angular velocity of the rotation includes the rate and direction of the rotation.

In step S3, the adjustment module 103 adjusts the volume of the handheld electronic device 1 according to the detected angular velocity of the handheld electronic device 1 rotation, that is, the rotation rate and direction of the handheld electronic device 1.

When the speed at which the handheld electronic device 1 rotates in a preset direction reaches a preset speed threshold, the adjustment module 103 will amplify the volume of the handheld electronic device 1 in a preset adjustment unit. When the rate of rotation of the handheld electronic device 1 in the opposite direction to the preset direction reaches the preset rate threshold, the adjustment module 103 will reduce the volume of the handheld electronic device 1 in the preset adjustment unit.

Or the preset rate threshold may be multiple, and each rate threshold corresponds to a preset adjustment unit. When the rate at which the handheld electronic device 1 rotates in the preset direction reaches one of the rate thresholds, the adjustment module 103 will amplify the volume of the handheld electronic device 1 in an adjustment unit corresponding to the rate threshold. When the rate at which the handheld electronic device 1 rotates in the opposite direction to the preset direction reaches one of the rate thresholds, the adjustment module 103 will reduce the volume of the handheld electronic device 1 in an adjustment unit corresponding to the rate threshold.

Step S4, when the application program that needs to output sound is closed, the execution module 101 turns off the angular velocity sensor 11.
