Problems solved by technology

[0003] However, when an electronic device using dual MIC anti-noise technology, such as a mobile phone, is placed on a flat surface (such as a table) during a call, especially when the hands-free is turned on, it is easy to generate howling, which greatly reduces the user experience; this is When the mobile phone turns on the Adaptive Noise Canceling (ANC, Adaptive Noise Canceling) device, the sound from the earpiece / speaker is reflected from the desktop and enters the secondary MIC, which destroys the user's listening experience

Abstract

The invention discloses a control method for an electronic device. The control method for the electronic device is applied to the electronic device with a self-adaptation silencer and a state information collector. The control method for the electronic device comprises the steps of detecting whether the electronic device is in a preset work state; obtaining a first state parameter collected through the state information collector when the electronic device is in the preset work state; judging whether the first state parameter meets a preset condition, wherein the preset condition is used for indicating that a rear shell of the electronic device is shielded; and if yes, controlling the self-adaptation silencer of the electronic device to be in a closed state. The invention further discloses the electronic device. By means of the technical scheme, the electronic device and the control method for the electronic device can eliminate the howling of the electronic device and improve the experience of users.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an electronic device and a control method. Background technique [0002] Currently, a dual-microphone (MIC, Microphone) anti-noise technology is widely used in electronic equipment. Among them, the main MIC is used to collect the voice of the user's call, and maintain a clear call stably; the secondary MIC is used to physically and actively eliminate noise. After collecting the external sound, after processing, it emits a sound wave opposite to the noise, and uses the principle of cancellation to eliminate the noise. [0003] However, when an electronic device using dual MIC anti-noise technology, such as a mobile phone, is placed on a flat surface (such as a table) during a call, especially when the hands-free is turned on, it is easy to generate howling, which greatly reduces the user experience; this is When the mobile phone turns on the Adaptive Noise Cancelin...
