After pending unit 301 received the digital command signal C1 that is transmitted by digital signal input unit 20, processing unit 301 was that converting digital command signal C1 is corresponding frequency-shift keying command signal C2, and transmitted frequency-shift keying command signal C2 and give FM module 302.
Thus, FM module 302 can be according to the frequency-shift keying command signal C2 that receives from processing unit 301, carries out the frequency modulation action obtaining a channel position, and produces numeric results signal R1 and be back to processing unit 301 carrying out the action back.
Processing unit 301 can reach the coder-decoder 40 that electrically connects with processing unit 301 with numeric results signal R1 after receiving numeric results signal R1.Coder-decoder 40 is after receiving numeric results signal R1; Coder-decoder 40 can carry out voice analog signal/digital signal bi-directional conversion according to ISN; Converting numeric results signal R1 into analog result signal R5, and analog result signal R5 is sent to voice-output unit 60.
Because voice-output unit 60 electrically connects with coder-decoder 40, and is therefore promptly exportable after voice-output unit 60 receives analog result signal R5, with the channel position after informing the instruction executed of user's frequency modulation and carrying out the frequency modulation action.Wherein, voice-output unit 60 for example can be dialled and put the loud speaker that receives analog result signal R5.
In addition, digital radio receiver frequency modulation device 10 of the present invention more can store the present channel position after frequency modulation moves according to user's actual need.When reality was used, user system imported save command by the button 201 or the induction pulley 202 of digital signal input unit 20 with the mode of mechanical type input.After the save command input, digital signal input unit 20 can convert these save commands to another digital signal earlier, and gives processing unit 301 with this another digital signal transfers.After pending unit 301 received another digital signal that is transmitted by digital signal input unit 20, processing unit 301 was that conversion digital signal is corresponding digital command signal C3 in the database, and transmitted digital command signal C3 and give storage element 303.Thus, storage element 303 can store the data of present channel position according to digital command signal C3, and after carrying out the storage action, produces the numeric results signal R2 of " channel storage " and be back to processing unit 301.Processing unit 301 can reach the coder-decoder 40 that electrically connects with processing unit 301 with numeric results signal R2 after receiving numeric results signal R2.Coder-decoder 40 is after receiving numeric results signal R2; Coder-decoder 40 can carry out voice analog signal/digital signal bi-directional conversion according to ISN; Converting numeric results signal R2 into analog result signal R6, and analog result signal R6 is sent to voice-output unit 60 with output.
Wherein, the frequency modulation instruction that the user is imported by button 201 or induction pulley 202 for example comprises: among a small circle frequency modulation, search for frequency modulation, frequency modulation, channel storage position or frequency modulation to stored channel position on a large scale automatically, but not as limit.
Fig. 2 is the present invention's embodiment sketch map of frequency modulation among a small circle, illustrates like the 2nd figure institute, when the user desires to carry out among a small circle frequency modulation, can carry out frequency modulation among a small circle by first button 2011 on the digital radio receiver frequency modulation device 10.For example; Digital radio receiver frequency modulation device 10 place channel position at present is FM89.3; When the user presses first button 2011, digital radio receiver frequency modulation device 10 will be carried out frequency modulation increasing progressively a minimum frequency modulation unit (+0.1), and after carrying out frequency modulation and accomplishing; With voice output FM89.4, is FM89.4 with the channel position after informing the instruction executed of user's frequency modulation and carrying out the frequency modulation action by earphone (not illustrating).
In addition, digital radio receiver frequency modulation device 10 of the present invention also can be carried out the frequency modulation among a small circle of the direction of successively decreasing, precisely because function mode is as the aforesaid function mode of frequency modulation among a small circle that increases progressively direction, so repeat no more.
Fig. 3 is the embodiment sketch map that the present invention searches for frequency modulation automatically, and is as shown in Figure 3, when the user desires to search for frequency modulation automatically, can search for frequency modulation automatically by second button 2013 on the digital radio receiver frequency modulation device 10.For example; If digital radio receiver frequency modulation device 10 place channel position at present is FM89.1; Then when the user presses second button 2013, digital radio receiver frequency modulation device 10 will carry out frequency modulation with increase progressively a plurality of minimum frequency modulation units near the station channel position FM89.5 of place channel position FM89.1 at present, and after carrying out frequency modulation and accomplishing; With earphone (not illustrating) voice output FM89.5, be FM89.5 with the channel position after informing the instruction executed of user's frequency modulation and carrying out the frequency modulation action.
In addition, digital radio receiver frequency modulation device 10 of the present invention also can be carried out the automatic search frequency modulation of the direction of successively decreasing, precisely because function mode is as the aforesaid automatic search frequency modulation function mode that increases progressively direction, so repeat no more.
Fig. 4 is for the present invention's embodiment sketch map of frequency modulation on a large scale, and is as shown in Figure 4, when the user desires to carry out on a large scale frequency modulation, can carry out frequency modulation on a large scale by the induction pulley on the digital radio receiver frequency modulation device 10 202.For example; If digital radio receiver frequency modulation device 10 place channel position at present is FM89.1; Then when the user presses induction pulley 202 and past clockwise direction slip; Digital radio receiver frequency modulation device 10 increases progressively a plurality of automatic search frequency modulation with execution, and the user stops to slide when responding to pulley 202, and digital radio receiver frequency modulation device 10 will stop to carry out the action that increases progressively a plurality of automatic search frequency modulation; And frequency modulation belongs to the immediate station channel of channel position position FM107.7 when the user stops to slide induction pulley 202; And after carrying out the frequency modulation completion,, be FM107.7 with the channel position after informing the instruction executed of user's frequency modulation and carrying out the frequency modulation action with earphone (not illustrating) voice output FM107.7.
In addition, digital radio receiver frequency modulation device 10 of the present invention also can be carried out the frequency modulation on a large scale of the direction of successively decreasing, precisely because function mode is as the aforesaid function mode of frequency modulation on a large scale that increases progressively direction, so repeat no more.
Moreover, seeing also Fig. 5, a technical characterstic of digital radio receiver frequency modulation device 10 of the present invention is that the user can import the frequency modulation instruction by voice mode, wherein Fig. 5 is the system block diagram of second embodiment of digital radio receiver frequency modulation device of the present invention.In second embodiment of digital radio receiver frequency modulation device of the present invention, digital radio receiver frequency modulation device 10 more increases and is provided with voice-input unit 50.Wherein, voice-input unit 50 electrically connects with coder-decoder 40.
