Problems solved by technology

However, the current echo suppression solutions for mobile phones cannot simultaneously adapt to whether the flip cover of the mobile phone is turned up or closed, whether the sliding cover is opened or closed, and whether the rotating screen is rotating or normal, which will cause echo problems, such as: when sliding When the phone is turned on to make a call, there is no echo problem, but when the cover is closed to make a call, there may be an echo problem, resulting in a decrease in call quality

Embodiment Construction

[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0011] In the prior art, there are many echo suppression algorithms. The echo suppression module of each mobile phone has its own echo suppression algorithm. However, the echo suppression parameters in the prior art are fixed and do not change with the shape of the mobile phone.

[0012] Such as figure 1 As shown, if the appearance of the mobile phone changes, the corresponding echo path will also change, so the corresponding echo suppression parameters should...

Abstract

The invention relates to a mobile phone with a variable exterior and an echo suppression method thereof. The echo suppression method comprises the following steps of: detecting whether the mobile phone initiates a call or not; if the call is initiated, detecting the form of the mobile phone; and adopting a corresponding echo suppression parameter according to the form of the mobile phone. The mobile phone and the method have the advantages that: due to the adoption of the method and the mobile phone of the invention, the mobile phone with the variable exterior suppresses echo by adopting different echo suppression parameters under the condition of different exteriors so as to achieve better echo suppression effect.

Description

technical field [0001] The invention belongs to the design of mobile communication terminals, in particular to a mobile phone with variable appearance and an echo suppressing method thereof. Background technique [0002] Existing mobile phones have become the necessities of life. As there are more and more types of mobile phones, there are more and more mobile phones with changeable appearance, such as flip cover, sliding cover, rotating screen, etc. There will be more mobile phones with more shapes in the future. . However, the current echo suppression solutions for mobile phones cannot simultaneously adapt to whether the flip cover of the mobile phone is turned up or closed, whether the sliding cover is opened or closed, and whether the rotating screen is rotating or normal, which will cause echo problems, such as: when sliding When the mobile phone is turned on to make a call, there is no echo problem, but when the cover is closed to make a call, there may be an echo pro...
