Embodiment Construction

[0063] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0064] refer to figure 1 , the embodiment of the present invention provides a control method of a portable speaker, comprising the steps of:

[0065] S1. Obtain the remaining power of the battery of the portable speaker.

[0066] In this step, the above-mentioned battery is generally a rechargeable battery, and the MCU of the portable speaker will always read the remaining power of the battery through the battery management system, such as obtaining the remaining power of the battery through commonly used ADC sampling.

[0067] S2. Search for a gain value corresponding to the remaining power in a preset gain list.

[0068] In this step, the above-mentioned gain list is a list with remaining power and its corresponding gain value, for example, when the remaining power is X, its corresponding gain value is Y and so on...

Abstract

The invention discloses a method and a device for controlling a portable sound box, wherein the method comprises the steps of acquiring a residual electric quantity of a battery of the portable soundbox; searching a gain value which corresponds with the residual electric quantity in a preset gain list; and adjusting the amplifier gain of the portable sound box according to the gain value. According to the method and the device for controlling the portable sound box, the amplifier gain is adjustable according to the residual electric quantity of the battery of the portable sound box, and system voltage ripple is reduced, thereby improving working stability of the chip of the portable sound box. Furthermore the method and the device have advantages of preventing loudspeaker sound distortionon the condition of low electric quantity, saving electric energy which is wasted in sound distortion caused by insufficient power supplying to the amplifier, and prolonging working time of the system.

Description

technical field [0001] The invention relates to the field of writing sound boxes, in particular to a control method and device for a portable sound box. Background technique [0002] Portable speakers are powered by batteries to power amplifiers to play sound signals. In the case of low battery power and high power amplifier output, it will cause insufficient power supply. In this case, the speaker is prone to distortion; at the same time, because the system voltage ripple is too large and the voltage becomes low, the chip often cannot work stably. Contents of the invention [0003] The main purpose of the present invention is to provide a control method and device for a portable sound box which can improve the chip work stability of the portable sound box. [0004] In order to achieve the purpose of the above invention, the present invention proposes a control method for a portable speaker, including: [0005] Obtaining the remaining power of the battery of the portabl...
