The specific embodiment:

Be embodiment of the present utility model with accompanying

drawing

1,2,3,4 below, be further detailed this use is novel:

The utility model includes receiver and the controller 3 that can realize that voice receive, export and have communication function that 1, one of a Digiplex is used to accept the signal of described Digiplex emission.Digiplex 1 is the single-chip that collection key scanning, remote control coding and an infrared emission are modulated to one, can select the integrated circuit of existing HT6221.Controller 3 is made up of a microprocessor, a sound circuit, is connected with a wireless receiving module on the microprocessor, and microprocessor is connected with ride with an input, output pin.Described microprocessor is one to be numbered the integrated circuit of W78E54; Described sound circuit is one to be numbered the integrated circuit of ISD2560.Described wireless receiver is the infrared ray receiver module, for making things convenient for user's use in practice, has adopted three to receive head mode in parallel, to improve the sensitivity that remote control receives.

As shown in Figure 1: its middle controller 3 is connected with ride 6, to finish communication and to obtain working power; Controller 3 is connected with wireless receiver 2, obtains the key of remote controller emission, and loudspeaker can be located at wireless receiver 2 inside.Controller 3 is connected with telephone receiver 5 and phonetic entry MIC4 simultaneously, to answer and phonetic dialing.

Wherein all component structure adapts to the environment inside car condition, and is small and exquisite, firm, is easy to install.The specification of connection lead meets the vehicle condition of all kinds of manned minibuses.Controller is installed in concealed location in the car, and phonetic entry MIC and infrared remote receiver are installed in the dead ahead of main steering position.

The circuit diagram of Digiplex, as shown in Figure 2, it comprises an encode circuit, a matrix keyboard and infrared module, wherein: encode circuit is made of the integrated circuit of numbering HT6221, its oscillator signal input pin X1, X2 are connected with an oscillating circuit of being made up of two electric capacity and quartz crystal, and the sequential oscillator signal that 455KHz is provided is to encode circuit.Pin C0～C4, the R0～R4 of encode circuit is connected with the matrix keyboard group.The matrix keyboard group includes 10 numerical keys 0～9, two function key * and #, key SET, an acknowledgement key OK, a talking mode shift key Ω, a cancel key C, two volume adjusting keys is set, repeating key VOL+ and subtract key VOL-and three consulting keys: medical help key+, the fault help key? with information service key i.The coding integrated circuit is connected with infrared transmitter with output pin DOUT, and it is made of a transistor driving one infrared diode.Coding integrated circuit HT6221 has low in energy consumption, the advantage of not launching during button not, and No. seven batteries of general two joints can use half a year.Itself support 32 key scanning functions, can be automatically with key and address code modulation bunchiness sign indicating number, the string sign indicating number is made up of 16 bit address sign indicating numbers, 8 keys and 8 key radix-minus-one complements, makes things convenient for receiving terminal identification and verification.

Sound circuit is made of the integrated circuit that is numbered ISD2560, and the voice that will record leave among the ISD2560 by corresponding address earlier, the voice segments that microprocessor will be play by address bus and control bus control, thus realize sound prompt function.Output pin SP+ and the SP-of voice IC send into driving circuit through volume control circuit.Voice driven is made of the integrated circuit that is numbered LM386, and circuit is simple and price is low, satisfies operating needs.Realize electric tuning amount by the integrated circuit that is numbered X9313, X9313 is that scalable is loud little by microprocessor control.

Mode of operation of the present utility model:

When phone was squeezed into, under the situation of engine starting, on-vehicle host inserted automotive acoustic speaker automatically, play phone ringing sound, after the ring 6 seconds two, and connecting incoming call automatically; Under the situation of engine off, incoming call is answered need be by the OK key, hears the prompt tone of " ticking ", the success of expression closing of the circuit.During end of conversation, on-vehicle host can be hung up the telephone automatically after the other side's on-hook, recovers the work of auto audio equipment, also can initiatively hang up the telephone by OK key or C key, and sound circuit can be pointed out phone on-hook.

When driving when dialling with the dialer button, whenever numerical key of input, promptly sending one transmits to main cartridge, microprocessor in the controller receives that promptly to give decoding behind this signal temporary, and the driving sound circuit is quoted corresponding voice, wait for then receiving next number, if dialing time interval long (as greater than 10 seconds) can be pointed out and be abandoned this group dialing and get back on hook automatically.After having imported number, steerman is pressed the OK key, and sound circuit can show that number has been transferred to or number is transferred to failure by different voice suggestions.

Steerman can be finished the telephone number that removing is imported because of maloperation by different buttons and corresponding voice suggestion equally, regulate the volume of talking state or other states, between handle talking mode and sound equipment talking mode, change, use medical treatment to seek help, fault is sought help and operation such as information service.

When steerman uses voice dial-up function, can be by next phonetic dialing start key, then under voice suggestion, utilize the MIC input by the name of called person, after microprocessor in the main cartridge receives and identifies this name, drive sound circuit and quote the corresponding phone number, and transfer to this number automatically.

Dialer is discerned the input name by setting up phone directory.After pressing the study Macintosh, voice suggestion enters the phone directory input state, can inform behind the dialer typing for the first time name that the user repeats voice for the first time, after more identical, reresents the input telephone number, and the prompting storage finished after operation was finished.The utility model has phone directory change, deletion and search-read function simultaneously.
