Embodiment
Outer bass strengthening loudspeaker circuit to mobile communication terminal among the present invention with above-mentioned feature is elaborated with reference to the accompanying drawings.
Fig. 1 is the structured flowchart of outer bass strengthening loudspeaker circuit one embodiment of the mobile communication terminal among the present invention.As shown in the figure, it includes following several sections: outer bass strengthening loudspeaker 10, and it is connected in mobile switch (M/S) 20, is used for the received audio signal line output of going forward side by side; Bass strengthening enlarging section 40 receives driving power and audio signal, after activating by above-mentioned driving power, the bass of the audio signal of above-mentioned input is strengthened (boost) operation, and it is outputed to above-mentioned mobile switch (M/S) 20; Portable terminal modulator-demodulator (MSM) 30, when above-mentioned outer bass strengthening loudspeaker 10 is connected in mobile switch (M/S) 20, receive the set control signal of above-mentioned connection correspondence, and to above-mentioned bass strengthening enlarging section 40 output driving powers, and the audio signal that outputs to internal loudspeaker (SPK).
Though it is not shown, above-mentioned outer bass strengthening loudspeaker 10 is by the plug-in unit (plug) and extension cable and the bass strengthening loudspeaker formation that are used to be connected to mobile switch (M/S) 20, and above-mentioned plug-in unit is made of ground connection (GND) terminal, control terminal, audio signal terminal.
Fig. 2 is the illustration figure of the M/S structure b among M/S structure a of the prior art and the present invention.As shown in the figure, mobile switch of the prior art (M/S) just is made of ground connection (GND) terminal and RF signal terminal, but the mobile switch (M/S) that uses in the present invention is to be made of GND terminal, control terminal, RF signal terminal, audio signal terminal.Above-mentioned RF signal terminal is the terminal that the terminal manufacturer uses when improving termination function according to designing requirement, will not be used when using outer bass strengthening loudspeaker 10 in the present invention.That is, during outer bass strengthening loudspeaker 10 in using the present invention, only using ground connection is GND terminal, control terminal, audio signal terminal, and is not connected with above-mentioned RF signal terminal.
The effect of above-mentioned audio signal terminal is that the audio signal output that the bass of exporting in the bass strengthening enlarging section 40 is strengthened arrives above-mentioned outer bass strengthening loudspeaker 10.
The effect of the control terminal of above-mentioned mobile switch (M/S) 20 is, to output to portable terminal modulator-demodulator (MSM) 30 at the input whether control signal of outer bass strengthening loudspeaker 10, one side joint ground or the voltage of receiving both sizings are (for example, Vcc) under the state, when being connected with above-mentioned outer bass strengthening loudspeaker 10, whether GPI0 stitch output earthed voltage or Vcc voltage to portable terminal modulator-demodulator (MSM) 30 confirm the connection of 30 pairs of outer bass strengthening loudspeakers 10 of above-mentioned portable terminal modulator-demodulator (MSM).Perhaps, whether the connection of the above-mentioned outer bass strengthening loudspeaker 10 of the automatic affirmation of obstructed overvoltage, but set menu is set in mobile communication terminal, and control according to user's selection.For example, constitute outer bass strengthening loudspeaker 10 and use schema entries, and when stating schema entry in the choice, activate (enable) above-mentioned bass strengthening enlarging section 40, thereby improve acoustical quality at bass.Below with reference to the connection of confirming outer bass strengthening loudspeaker 10 by control terminal whether, action of the present invention is described.
The action of the present invention of structure describes to having as above below.
When the user is connected to the mobile switch (M/S) 20 of mobile communication terminal with outer bass strengthening loudspeaker 10, connection between the plug-in unit by outer bass strengthening loudspeaker 10 and the control terminal of mobile switch (M/S) 20, Vcc voltage will be input in the GPIO stitch of mobile switch (MSM) 30.
Mobile switch (M/S) 30 identifies the connection status of outer bass strengthening loudspeaker 10 according to the Vcc voltage of importing in the above-mentioned GPIO stitch, and makes its activation to bass strengthening enlarging section 40 supply driving powers.
The bass strengthening enlarging section 40 that is activated receives the audio signal that above-mentioned portable terminal modulator-demodulator (MSM) 30 outputs to internal loudspeaker SPK, the bass of the audio signal of above-mentioned input is strengthened, and with the audio signal terminal of above-mentioned audio signal output through intensive treatment to mobile switch (M/S) 20.
Be input to the audio signal that the bass of mobile switch (M/S) 20 audio signal terminals is strengthened, will output in the interconnective outer bass strengthening loudspeaker 10.At this moment, the audio signal of output will output to internal loudspeaker (SPK) simultaneously in the above-mentioned portable terminal modulator-demodulator (MSM) 30.
In aforesaid the present invention,, thereby can improve the acoustical quality of mobile communication terminal because it utilizes outer bass strengthening loudspeaker to improve the bass ability to play of the tinkle of bells, music etc. of output.
