Embodiment
Mobile phone with the outer connection function of microphone provided by the utility model, clearer, clear and definite for making the purpose of this utility model, technical scheme and advantage, below the utility model is further described with reference to the accompanying drawing embodiment that develops simultaneously.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
A kind of mobile phone that the utility model embodiment provides with the outer connection function of microphone, as shown in Figure 1, comprise a mobile phone body 100 and be arranged on the interior circuit board 110 of mobile phone body, and on described mobile phone body 100, also be provided with microphone 120, and audio interface 130.
As shown in Figure 2, and described circuit board 110 is provided with baseband chip 111, and described baseband chip 111 is connected with audio interface 130 with described microphone 120 respectively.
Described microphone 120 is used for transferring the voice signal of outside to audio signal, and described audio signal is sent to described baseband chip 111;
Described baseband chip 111 is used to receive described audio signal, and described audio signal is carried out processing and amplifying; And with the audio signal of institute's processing and amplifying by described audio interface 130 outputs.Be that baseband chip 111 is mainly finished the audio signal that microphone 120 is brought and gathered, then via 3.5 inches AUDIO JACK(audio interface) 130 outputs.
Preferably, as shown in Figure 2, described audio interface 130 is 3.5 inches a earphone interface, because 3.5 inches earphone interface is as a standard, present mobile phone all is furnished with this interface.And the input of general loudspeaker 200 also is 3.5 inches a earphone interface, as shown in Figure 2, therefore can very easily loudspeaker 200 be received on the mobile phone.External loudspeaker 200 as shown in Figure 2 also is the AUDIO JACK(audio interface by 3.5 inches) carry out wired connection.
Further, in described baseband chip 111, be provided with amplifying unit 112, be used for the audio signal that described microphone 120 sends is amplified, as shown in Figure 2, described microphone 120 is connected with the amplifying unit 112 of described baseband chip 111 with 12 by two jamproof holding wires 11, and wherein a holding wire 12 also connects with reference to ground by first resistance R 1, and another root holding wire 11 is connected with described baseband chip 111 by second resistance R 2.Described first resistance and described second resistance are preferably 2K ohm.
Further, as shown in Figure 2, described baseband chip 111 also is used for, and will switch on Audio_R and the Audio_L again by described audio interface output through the internal audio frequency path through the audio signal of processing and amplifying.
