Problems solved by technology

[0003] However, when the smart hardware device is in a noisy environment, for example, in a crowded department store, the exclusive counter uses the smart hardware device to demonstrate product functions, and there are often two situations that affect the user experience
First, the volume control device has been adjusted to the maximum volume, but in the case of external noise interference, the external sound of the smart hardware device is still difficult to hear clearly; second, when the volume control device is adjusted to the maximum volume, although the external sound can be Resist the influence of external harsh noise so that users can hear clearly, but when the external environmental noise becomes weak or disappears, the external volume will appear too noisy. At this time, it is necessary to manually adjust the volume of the device to match the external environmental noise. Changes to obtain a better user experience, the operation is more troublesome

Abstract

The embodiment of the invention discloses a volume adjustment method and device and equipment. The method comprises the steps of obtaining environment noise through a microphone; triggering volume gain adjustment if the volume of the environment noise reaches a preset volume threshold value; adjusting a volume gain factor of an audio signal of at least one frequency band in to-be-played audio signals according to audio frequency characteristics of the to-be-played audio signals; and carrying out the volume gain adjustment on the audio signal through adoption of the volume gain factor of each frequency band. Through application of the technical scheme, an effect that the loudspeaking volume of a smart hardware device can match an external noisy environment smartly is achieved, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to sound control technologies, and in particular to a volume adjustment method, device and equipment. Background technique [0002] For an intelligent hardware device with a microphone and a speaker, the operation interface is generally provided with a device for controlling the volume of the speaker. Usually, the loudspeaker volume is determined by the hardware design of the device and the system software design, and users can adjust the volume according to their own needs. [0003] However, when the smart hardware device is in a noisy environment, for example, in a crowded department store, the exclusive counter uses the smart hardware device to demonstrate product functions, and there are often two situations that affect the user experience. First, the volume control device has been adjusted to the maximum volume, but in the case of external noise interference, the external sound of the smart hardware dev...
