Apparatus and method for automatically switching volume control mode

Abstract

The present invention relates to a method of automatically switching volume control mode, which can be used for automatically switching the volume into the fine-tuning mode when the volume is regulated to have a high value through rough adjustment. The method comprises the following steps: a first preset value and a second preset value are stored in the system; wherein, the first preset value is larger than the second preset value; the control mode is first judged when the volume control signals occur; the rough adjustment is adopted in the mode of rough adjustment; when the volume is higher than or equal to the first preset value in the process of rough adjustment, the volume is automatically switched into the fine-tuning mode. The method also comprises the following steps: the volume is processed by fine tuning in the fine-tuning mode; when the volume is lower than or equal to the second preset value in the fine-tuning process, the volume is automatically switched into the mode of rough adjustment. Therefore, the volume adjustment is automatically switched into the fine-tuning mode after the volume is regulated to have a higher volume value through rough adjustment, which prevents the damage to ears caused by the sudden increase of the volume; simultaneously, the volume can be finely tuned within a certain range; thus the method reflects the humanity.

Description

technical field [0001] The invention relates to a volume adjustment device and method, in particular to a device and method capable of automatically switching volume adjustment modes. Background technique [0002] At present, handheld devices with MP3 or FM radio functions are becoming more and more common, and people's requirements for the performance of these handheld devices are also increasing. Among them, there is a higher requirement for volume adjustment, and now the volume adjustment of handheld devices generally only There are 5 to 6 gears, so that the user cannot make finer adjustments, and it is difficult to adjust the volume to the user's satisfaction. [0003] In a patent document published by the China Intellectual Property Office on February 13, 2002, the publication number is "CN 1335693A", and the title is "Input Device, Reproduction Device, and Volume Adjustment Method", which discloses a device that can roughly adjust the volume. In addition, the device a...

[0004] However, no matter the general handheld device or the aforementioned prior art, there is no effective protection for the user's ears. When the user adjusts to a larger volume value, if the user still chooses to adjust the volume in a coarse manner, the volume will increase. If the volume is increased by a large amount, the user's ears will be damaged due to the sudden increase of the volume, and it is easy to cause misoperation by switching the adjustment mode through the length of the key press or the speed of the knob rotation. If the user selects the fine-tuning mode when adjusting , and due to careless operation, the key time is short or the knob is rotated quickly and the adjustment mode is switched to the coarse adjustment mode, so that the volume deviates from the ideal volume
