Problems solved by technology

[0004] However, people often use mobile phones to make calls in noisy environments, but in noisy environments, ambient noise will be input into the headset microphone and transmitted to the other party, which will affect the quality of the call, or even make the call impossible

Embodiment Construction

[0033] see first figure 1 , figure 1 is a schematic diagram of the circuit structure of the mobile phone according to the first embodiment of the present invention. like figure 1 As shown, in this embodiment, the mobile phone of the present invention includes a main microphone 101 , a pluggable earphone microphone 102 on the mobile phone, a baseband signal processing chip 103 and a noise suppression circuit 104 .

[0034] Wherein, the baseband signal processing chip 103 is used to detect the current call state of the mobile phone to determine whether the mobile phone enters the earphone call state, and uses the main microphone 101 to obtain the first environmental noise signal when the mobile phone enters the earphone call state. The noise suppression circuit 104 is configured to perform noise suppression processing on the call signal acquired by the earphone microphone 102 according to the first ambient noise signal, so as to obtain a noise suppressed call signal.

Abstract

The invention discloses a conversation signal processing method for a cell phone. The method comprises the steps of: detecting a current conversation state of the cell phone so as to judge whether the cell phone enters an earphone conversation state; when the cell phone is in the earphone conversion state, acquiring a first environment noise signal by using a main microphone; and performing noise inhibition processing on a conversation signal obtained through an earphone microphone according to the first environment noise signal, so as to obtain the conversation signal subjected to the noise inhibition processing. The invention further discloses the cell phone. Accordingly, by means of the technical scheme provided by the invention, the environment noise signal in the conversation signal acquired by the earphone microphone can be removed by using the environment noise signal to perform the noise inhibition processing when a user is in the earphone conversation state, and thus, a user is ensured to be free from the influences of environment noises when holding a conversation by using the earphone, and the conversation quality is ensured.

Description

technical field [0001] The invention relates to the field of consumer electronics, in particular to a mobile phone and a call signal processing method thereof. Background technique [0002] With the improvement of living standards, mobile phones are becoming more and more popular in daily life. [0003] As a portable communication tool, mobile phones are used in all environments from quiet nights to busy downtown areas. The mobile phone is generally equipped with earphones, and the user can listen to the sound signal played by the mobile phone through the earphone, and the earphone is generally provided with an earphone microphone, and the user can use the earphone and the earphone microphone to listen to and send the sound signal. Generally speaking, the user is equipped with an earphone The headset of the microphone can ensure that the user can still make a call when the user cannot hold the mobile phone by the ear, which is especially suitable for the user to use when dr...
