Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] refer to figure 1 , figure 1 It is a flowchart of an embodiment of the method for adaptively adjusting the frequency response of the present invention, including:

[0028] Step S101: When the terminal detects that the amplitude of the user's voice is smaller than the first threshold, the terminal's sound pickup picks up the ambient sound to obtain the frequency response curve and loudness of the ambient sound.

[0029] A sound pickup is an acoustic-electric converter that can pick up sounds, including but not limited to various types of microphones.

[0030] Frequency response is the frequency response, which refers to the phenomenon that when an audio signal output with a constant voltage is connected to the system, the sound pressure generated by the speaker increases or attenuates with the frequency, and the phase changes with the frequenc...

Abstract

Disclosed are a method and a terminal for adaptively adjusting a frequency response. The method comprises: a sound pickup of a terminal picking up environmental sound, to obtain a frequency response curve and loudness of the environmental sound; comparing the frequency response curve and loudness of the environmental sound with a preset frequency response curve and loudness of an internal circuit of the terminal; and adjusting a frequency response curve and loudness of the internal circuit of the terminal according to a comparison result, so that differences between the frequency response curve and loudness of the internal circuit of the terminal and the frequency response curve and loudness of the environmental sound are larger than preset conditions in a preset frequency range. By means of the method, the present invention can be applied to a call scenario of a terminal and can adjust both a frequency response and a loudness.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a method and a terminal for adaptively adjusting frequency response. Background technique [0002] With the development of audio technology, there are more and more audio tests for mobile phones. Among them, the test items of call frequency response originated from the 3rd Generation Partnership Project (3GPP), 3rd Generation Partnership Project 2 (3GPP2) and International Telecom The specific requirements in the agreement of the Union (ITU), in which there are complete requirements for the frequency response test items. Frequency response refers to the phenomenon that when an audio signal output with a constant voltage is connected to the system, the sound pressure generated by the system increases or attenuates with the frequency, and the phase changes with the frequency. Usually, after the frequency response adjustment is completed in the development and design process, it is ...
