Embodiment
The 3D that describes the mobile communication terminal among the present invention with reference to the accompanying drawings in detail embodies the effect and the effect of device.
The skeleton diagram that Fig. 3 points out out the 3D sound of the mobile communication terminal among the present invention to embody apparatus structure, Fig. 4 point out out the 3D sound of the mobile communication terminal among the present invention to embody the block diagram of device example structure.
As shown in Figure 4, it includes following several sections: MIDI generator 100, carry out set processing to midi signal, and export left ring signal (Left_Ring_Signal) and right ring signal (Right_Ring_Signal); The 1st amplifier 200, left ring signal (Left_Ring_Signal) to output in the above-mentioned MIDI generator 100 amplifies, and the negative ring signal (Ring_Left_N) of a positive ring signal (Ring_Left_P) in the left side of correspondence and a left side is exported by the 1st loud speaker 400; The 2nd amplifier 300, the right ring signal of exporting in the above-mentioned MIDI generator (Right_Ring_Signal) is amplified, and the right positive ring signal (Ring_Right_P) and the right negative ring signal (Ring_Right_N) of correspondence are exported by the 2nd loud speaker 500; Analog switch 700, according to the control signal that receives, (Voice_P Voice_N) or select positive ring signal in an above-mentioned left side (Ring_Left_P) and right positive ring signal (Ring_Right_P), and exports with receiver 800 by voice call to select voice signal; MSM600 receives above-mentioned voice signal, and above-mentioned voice signal is encoded, and exports with set rank, and according to the pattern of mobile communication terminal, output is used to switch the control signal of above-mentioned analog switch 700 simultaneously.
At first, when the pattern of mobile communication terminal is call mode, the MSM600 received speech signal, and above-mentioned voice signal encoded, export with set rank, control above-mentioned analog switch simultaneously and switch on the voice call path.
Thus, voice switch switches to the voice call path, and with the voice signal of exporting among the above-mentioned MSM, exports to the outside with receiver by voice call.
When the pattern of above-mentioned mobile communication terminal is the MIDI play mode, MIDI generator 100 is according to the control signal of above-mentioned MSM600, midi signal is carried out set processing, export left ring signal (Left_Ring_Signal) and right ring signal (Right_Ring_Signal) simultaneously.
Meanwhile, the left ring signal (Left_Ring_Signal) of output amplifies in 200 pairs of above-mentioned MIDI generators 100 of the 1st amplifier, and the negative ring signal (Ring_Left_N) of a positive ring signal (Ring_Left_P) in the left side of correspondence and a left side is exported by the 1st loud speaker 400; 300 right ring signals (Right_Ring_Signal) to output in the above-mentioned MIDI generator 100 of the 2nd amplifier amplify, and the right positive ring signal (Ring_Right_P) and the right negative ring signal (Ring_Right_N) of correspondence are exported by the 2nd loud speaker 500.
At this moment, analog switch 700 is according to the control signal (Sel) of MSM600, to switch on the MIDI broadcast path, thereby select positive ring signal in an above-mentioned left side (Ring_Left_P) and right positive ring signal (Ring_Right_P), and export with receiver 800 by voice call.
That is, above-mentioned voice call differs big or small signal with producing in the receiver 800 between positive ring signal in an above-mentioned left side (Ring_Left_P) and the right positive ring signal (Ring_Right_P), thereby on the whole than the additional sound that produces 1/2 size in the prior art.
That is to say, in the present invention, when mobile communication terminal is in the MIDI play mode, except a left side/right loud speaker, use in the receiver in voice call, the left positive signal of the left speaker of input 3D sound and the right positive signal of right speaker, thus the MIDI sound increase that plays out has 1/2 times sound, while is owing to 3 direction output sounds, the also corresponding lifting of its tonequality.
As above detailed described embodiments of the invention, just in order to offer some clarification on technology contents of the present invention, the present invention is not confined to aforesaid embodiment, in the scope of stipulating in not exceeding basic fundamental thought of the present invention and claims, the operator of relevant industries can carry out various deformation to it.
As above described in detail, effect of the present invention is, when mobile communication terminal is in the MIDI play mode, except a left side/right loud speaker, use in the receiver in voice call, the left positive signal of the left speaker of input 3D sound and the right positive signal of right speaker, thus reach best 3D effect when playing MIDI.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
