Abstract
The utility model relates to a DSP-based sound-control television remote controller, comprising a sound-control identification system, a modulator, an amplifier, and an infrared transmitting tube, which are sequentially connected. A sound-control key switch is arranged between the sound-control identification system and the modulator. An encoder is further connected to the modulator. A keying matrix switch is connected with the encoder. The DSP-based sound-control television remote controller disclosed by the utility model has a speech recognition capability and is capable of conducting dialing through sounds so that a user does not need to remember corresponding tedious channel codes and names, the time used for searching an expected channel is greatly reduced, and the controller has a wide and good market prospect in user groups, such as automobile drivers, patients, senior citizens, and children.
Description
[technical field]
The utility model relates to a kind of TV remote controller, is specifically related to a kind of acoustic controlled telephone remote controller based on DSP (Digital Signal Processing, Digital Signal Processing), belongs to the remote controller technical field.
[background technology]
Usually the emission of colour TV remote signal, be exactly with the corresponding control command of certain button and systematic code (by 0 and 1 sequence that forms), is modulated on the carrier wave in 32～56KHz scope, then through amplifying, drive infrared transmitting tube, signal launched.
On the common TV set remote-controller, the user can only dial by craft and carry out alternately with television set, and eyes cannot see pocket-handkerchief or the handicapped crowd of hand can't use this key type remote controller.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved acoustic controlled telephone remote controller based on DSP that has, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of acoustic controlled telephone remote controller based on DSP simple in structure, easy to use.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of acoustic controlled telephone remote controller based on DSP, and it comprises acoustic control recognition system, modulator, amplifier and the infrared transmitting tube that connects successively; Wherein, be provided with an acoustic control key switch between described acoustic control recognition system and modulator; Further be connected with an encoder on described modulator, be connected with a keying matrix switch on described encoder.
Acoustic controlled telephone remote controller based on DSP of the present utility model further is set to: described acoustic control recognition system comprises microphone, codec chip, DSP process chip, main controller, memory modules and modulation circuit; Wherein, described microphone, codec chip, DSP process chip, main controller are connected with modulation circuit and are connected; Described memory modules is connected on the DSP process chip.
Acoustic controlled telephone remote controller based on DSP of the present utility model also is set to: further be connected with a loud speaker on described codec chip; Be connected with a Flash module on described DSP process chip.
Compared with prior art, the utlity model has following beneficial effect: the acoustic controlled telephone remote controller based on DSP of the present utility model has speech recognition capabilities, can dial by enough sound, make the user not need to remember again the corresponding of those loaded down with trivial details channel identification codes and title, greatly reduced the search anticipation channel time used, the driver, patient, the elderly has good widely market prospects in the user groups such as children.
[description of drawings]
Fig. 1 is the schematic diagram of the acoustic controlled telephone remote controller based on DSP of the present utility model.
Fig. 2 is the schematic diagram of the acoustic control recognition system in Fig. 1.
[embodiment]
See also shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of acoustic controlled telephone remote controller based on DSP, and it is comprised of several parts such as acoustic control recognition system 1, modulator 2, amplifier 3 and infrared transmitting tube 4 that connect successively.
Wherein, be provided with an acoustic control key switch 5 between described acoustic control recognition system 1 and modulator 2.Channel name or rating mode code that this acoustic control recognition system 1 can be said according to the user carry out automatic search and dialing.Described acoustic control key switch 5 is used for starting this acoustic control recognition system 1.Described amplifier 3 is used for dialing signal is amplified, and driving infrared transmitting tube 4 is launched signal.
Further be connected with an encoder 6 on described modulator 2, be connected with a keying matrix switch 7 on described encoder 6, thereby can realize push-button dialing.
Further, described acoustic control recognition system 1 comprises microphone 11, codec chip 12, DSP process chip 13, main controller 14, memory modules 15 and modulation circuit 16.Wherein, described microphone 11, codec chip 12, DSP process chip 13, main controller 14 are connected with modulation circuit successively and are connected.Described memory modules 15 is connected on DSP process chip 13.Further be connected with a loud speaker 17 on described codec chip 12.Be connected with a Flash module 18 on described DSP process chip 13, the parameter after coding leaves in the Flash module 18 of expansion preserves.
The operation principle of described acoustic control recognition system 1 is as follows: the user is by microphone 11 input command informations, complete the A/D of voice signal by codec chip 12, the D/A conversion, explain phonetic order and send it to DSP process chip 13, DSP process chip 13 is communicated by letter with main controller 14 by speech recognition, by main controller 14, voice signal is delivered in modulation circuit 16, and be delivered in modulator 2 by modulation circuit 16.
Above embodiment is only the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., within all should being included in the protection range of this creation.
