Embodiment
Voice and music are synthesized two kinds of possible practices.A kind of is that music is used as speech processes.Just, the voice of two channel formulas (two-channel speech), the voice of entering for record are background song first first.Another kind then produces music rhythm with melody generation device (melody generator), and again with voice mixing, its method is simple than the former, but can't show the effect of song.How emphasis of the present invention utilizes the process of switching voice and music, and the voice that card is recorded have background music or audio.In order to allow ard issuers can arbitrarily add the voice of oneself, the present invention at voice and the synthetic part of music, proposes three kinds of possible embodiment especially.
Fig. 1 is two channel processing modes, is background music or audio are regarded general speech processes.Fig. 1 shows that one is installed in the functional block diagram of IC on the card.One background signal memory storage 102 is arranged, in order to store background signal such as music or song on the IC.Because background signal is generally and records in advance, so background signal memory storage 102 can be Mask ROM, EPROM, EEPROM, or Flash Memory.The voice signal that ard issuers is imported then is stored in voice signal memory storage 101.Because voice signal is that the usefulness of sending out Queensland card people recording will be provided, so voice signal memory storage 101 can be RAM, EPROM, EEPROM, or Flash Memory.Except that memory storage, most importantly a signal processing apparatus 103 in order to read voice signal, is exported it and the synthetic back of background signal again.Signal processing apparatus 103 mainly comprises an analog/digital signal conversion device 106, one compression sets 107, one device sound mixings 108, one decompressing devices 109, and a digital/analog signal converter 110.
When the recording simulation, voice signal is through loudspeaker 104, input analog/digital signal conversion device 106, so that voice signal is converted to digital signal, voice signal input compression set 107, with voice signal with PCM, ADPCM, or u | modes such as LAW are encoded, and are stored in voice signal memory storage 101 then.When playback is simulated, behind card receiver's starting switch, voice signal and background signal export device sound mixing 108 to synthesize audio signal output by voice signal memory storage 101 and background signal memory storage 102 respectively, earlier through the u of decompressing device 109 | behind the gunzip of LAW or ADPCM etc., input digit/analog signal converter 110 again, to convert it to simulating signal, by loudspeaker 105 outputs.When audio mixing, the present invention utilizes the skill of switching, and the volume that makes background signal is changed from small to big from large to small earlier again, and when the volume of background signal diminished, the volume of voice signal just occurred therebetween.
For reducing cost, if background signal is general music rhythm, a then available melody generator (melodygenerator) replaces, and presses the processing of voice signal and background signal is come respectively.Fig. 2 shows a background signal generation device 202, can or be contained in functional block diagram on the different IC respectively with signal processing apparatus 202 shared same IC.Because the processing of voice signal and background signal separates, therefore, signal processing apparatus 202 is handled mainly to be voice signal.Signal processing apparatus 202 comprises an analog/digital signal conversion device 204, one compression sets 205, one decompressing devices 206, and a digital/analog signal converter 207.Background signal generation device 208 is a melody generator, as electronics audio generator, can produce required background music or audio, and by signal processing apparatus 202 its volumes of control, at reasonable time background signal is imported device sound mixing 203.Device sound mixing 203 switches voice signal and background signal in good time, and for example, in the front and back that voice signal is play, the volume of background signal is bigger, and when voice signal was play, the volume of background signal was less.Different with Fig. 1 is, the device of Fig. 2 is an audio mixing when playing, and the device of Fig. 1 then is an audio mixing when reading.
When recording mode, voice signal is by microphone 210 input signal treating apparatus 202.Voice signal passes through compression set 205 again with PCM after being converted to digital signal through analog/digital signal conversion device 204, ADPCM, u | the mode of LAW etc. is encoded, and is stored in voice signal memory storage 211 then.When playback is simulated, signal processing apparatus 202 reads the voice signal in the voice signal memory storage 206, passes through decompressing device 206 with PCM, ADPCM, u | the mode of LAW etc. is encoded, and is converted to simulating signal through digital/analog signal converter 205 then.Device sound mixing 203 is responsible for mixing voice signal and background signal, and the volume of control background signal and voice signal output.When audio mixing, device sound mixing 203 is turned the volume of background signal down automatically gradually, with outstanding voice signal.When voice signal finishes, automatically the volume of background signal is transferred greatly gradually again, to finish the effect of audio mixing.At last, by loudspeaker 209 outputs.
The processing mode of Fig. 3 is handled for make audio mixing earlier before recording, just earlier with behind voice signal and the background signal audio mixing, again in the input store.During broadcast, as long as the program through decompressing just can make the card receiver hear the voice with background signal.Background signal generation device 301 can produce required background music or audio.When recording mode, when voice signal was imported device sound mixings 303 via loudspeaker 302, background signal generation device 301 was also imported background signal device sound mixing 303 simultaneously, to carry out audio mixing.The function of device sound mixing 303 is identical with Fig. 1, Fig. 2 with effect.Audio signal after the audio mixing is passed through compression set 306 again with PCM after converting digital signal to through the analog-digital converter 305 in the signal processing apparatus 304, ADPCM, u | the mode of LAW etc. is encoded, and is stored in audio signal memory storage 309 then.When the playback pattern, signal storage device 309 output audio signal, process decompressing device 307 is with PCM, ADPCM, u | the mode of LAW etc. is encoded, be converted to simulating signal through digital/analog signal converter 308 then after, play back by loudspeaker 310.
The above only is preferred embodiment of the present invention, and has reached extensive practical effect, and all various variations and modifications of being done according to the present patent application claim scope all still belong in the scope that patent of the present invention contains.
