Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0034] Such as figure 1 As shown, the flow of a method for adjusting audio output loop filter parameters provided by the present invention is described in detail as follows:
[0035] In step S101, the first audio module sends a first audio signal.
[0036] In this article, "first" and "second" do not represent a sequence relationship, but are only used to distinguish different audio modules or audio signals. In the embodiment of the present invention, the first audio module may be composed of an audio processor, an audio transmission channel, a sound-generating electro-acousti...

The invention belongs to the field of mobile communication, and provides a method and device for adjusting filtering parameters of an audio output circuit and a mobile terminal. The method includes the steps that a first audio module sends first audio signals; a second audio module collects the first audio signals to form second audio signals; the first audio signals and the second audio signals are compared to determine the cut-off frequency; according to the cut-off frequency, the filtering parameters of the audio output circuit are set. The cut-off frequency is determined by comparing the first audio signals and the second audio signals, and the filtering parameters of the audio output circuit are set according to the cut-off frequency, so that the audio signals after passing through a filter are automatically processed and matched with a sound production component, and the problems that in the prior art, the audio signals can not be matched with the sound production component, and manual adjusting efficiency is low are solved.
Description
technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method, a device and a mobile terminal for adjusting filtering parameters of an audio output loop. Background technique [0002] In the research and development process of mobile terminals, due to the performance limitations of sound-generating components such as earpieces or speakers, it is necessary to adjust the parameters of the audio output loop filter of the baseband processor according to the characteristics of the sound-generating components to achieve the frequency response of the output audio signal and the sound-generating components. match. In the process of R&D and production, adjusting according to the above-mentioned method brings problems of low efficiency and poor matching effect, including: 1. R&D personnel need to repeatedly debug so that the audio signal can be matched with the sound-generating parts after passing through the above-mentioned f...
