Embodiment Construction

[0014] Such as figure 1 As shown, a system for controlling volume with a single volume adjustment key in the present invention includes a gravity acceleration sensor opening module 101, an acceleration acquisition module 102, an acceleration acquisition times counting module 103, a volume increase module 104, and a volume decrease module 105.

[0015] The acceleration of gravity sensor opening module 101 is used to open the acceleration of gravity sensor by long pressing the single volume adjustment key.

[0016] The acceleration collection module 102 uses the acceleration of gravity sensor to collect the acceleration value and direction of any axis or any combination of two axes in the X-axis, Y-axis, and Z-axis every time T, as described in this embodiment. The time T is 50ms, and the acceleration in the X-axis direction is mainly collected.

[0017] The acceleration collection times counting module 103 is used to add 1 to the variable sum when the acceleration value is gre...

Abstract

The invention discloses a method for controlling volume via a single volume regulation key. The method is characterized by comprising the following steps of: pressing the single volume regulation key for a long time to start a gravity acceleration sensor; acquiring an acceleration value and the acceleration direction in any one axial direction or combination of any two axial directions of an X axis, a Y axis and a Z axis once at intervals of time T through the gravity acceleration sensor; if the acceleration value is more than a preset acceleration threshold, adding 1 to a variable sum, wherein the variable sum is the acceleration acquisition times; if the variable sum is more than a preset threshold times, turning up or down the volume according to the property of the acceleration direction. The method in the invention, combined with the gravity acceleration sensor, can realize volume control via the single volume regulation key, can save structure space of a mobile phone undoubtedly to meet the modern pursuit of designing light and thin mobile phones, and also can reduce the cost of the mobile phones.

Description

Technical field: [0001] The invention relates to a method and system for controlling volume with a single volume adjustment key. Background technique: [0002] Existing mobile phone, its volume regulation has two kinds usually: a kind of is to utilize two volume keys to realize regulation, and another kind is to utilize software to realize regulation. [0003] The method of using two volume buttons to adjust must use two volume buttons, namely the volume up button and the volume down button, which are used to control the increase and decrease of the volume respectively. It is beneficial to save the structural space of the mobile phone and reduce the cost of the mobile phone. [0004] The realization of software adjustment requires a series of menu operations, and the process is more complicated. Invention content: [0005] The object of the present invention is to provide a method for controlling volume with a single volume adjustment key. [0006] A method for controll...
