Description
Technical field
The utility model relates to a kind of wireless speech device of tool MP3 coding and decoding/recording chip, it is fast that the information products of You Zhike and tool wireless transmission carry out the mutual biography of MP3 audio format, and by its MP3 coding and decoding/recording chip message is play after coding and decoding or recorded, and this wireless speech device can be a wireless headset or radio earphone microphone.
Background technology
Because the compress technique of MP3 (MPEG Layer 3) sound heals and becomes ripe in recent years, use this technology general unpressed music information can be compressed to 1: 12, or even it is littler, and remain on the distortion rate that people's ear almost can't distinguish, and possess the quality of CD music, but general MP3 is the mode accessing file with exclusive audio format, usually must use a computer and cooperate corresponding playing program, begin to play the audio files of MP3, and common playing program has WinAMP, so, at present at the popular on the market walkman that can play-over the MP3 format file, it does not need the auxiliary of computing machine, just the mp3 file of compression can be play-overed out, but the user must purchase a MP3 walkman separately.
Yet, on at present popular 3C information products, more and more many people have and have the transmitting information wirelessly product, as information products (walkman CD player, PDA) etc., making things convenient for data transmission to use, and can utilize and connect wireless headset or message is listened to or recorded to wireless microphone.
See also shown in Figure 1, the circuit box synoptic diagram that is connected with the wireless speech device for the existing information product, it mainly utilizes information products (walkman CD player, PDA) in 10 universal serial bus connector (USB Connecter) 110 or flash memory/storage card (Flash/MemoryCard) 120 with the MP3 format file through 140 decodings of USB memory storage Magnetic Disk Controller (USB StorageDisk Controller) 130 control MP3 coding and decoding/recording chips, to decipher back message again and convert simulating signal to by change-over circuit 150, the continuous amplifying circuit 160 of delivering to, and can deliver to the source of sound input socket 210 of wireless launcher through source of sound connecting line 180 by source of sound accessory power outlet 170, launch through wireless module 220 again, then by the wireless transmission interface 230 of wireless headset 20 with the message that receives after amplifying circuit 240 changes volumes, deliver to loudspeaker 250 places and begin sounding, so, as from the foregoing, its information products (walkman CD player, PDA) must dock on 10 the source of sound accessory power outlet 170 and have wireless launcher to begin and wireless headset 20 is done message transmission; But above-mentioned existing product has following several disappearances when using:
One, its information products (walkman CD player, PDA) 10 must be purchased the MP3 player in addition, play MP3 music format file.
When two, listening to the MP3 music, must carry MP3 player or notebook computer, PDA(Personal Digital Assistant), pocket PC information products such as (Packet PC), very inconvenient.
Three, use notebook computer, PDA(Personal Digital Assistant), pocket PC information products such as (Packet PC) to play the MP3 music format, make that must use the MP3 playout software to carry out coding and decoding uses.
So, how to solve above-mentioned disappearance with not enough, just for being engaged in the direction place that the industry has utmost point desire to improve.
Summary of the invention
