Abstract
This invention discloses one blue tooth cell phone as wireless audio output earphone, which is characterized by the following: audio input wire fixed on the cell phone with audio output interface and audio mode conversion to convert audio frequency analogue signal into digital signals. This invention can be used as wireless audio output earphone blue tooth cell phone suitable for any situations.
Description
Technical field
The present invention relates to the mobile phone technical field, particularly relate to the bluetooth cellular phone that can serve as wireless audio output earphone.
Background technology
Mobile phone (mobile phone) is the important tool that people exchange, link up, get in touch, and mobile phone is light with it, thin, little characteristics and be subjected to people's favor, has spread in the middle of the daily life as important communication tool.The mobile phone products of Bluetooth stereo function has appearred having in a large number in the market, Bluetooth technology itself has the wireless communication distance of 10m, and the ANTENN AUDIO earphone can adopt radio frequency chip to realize that the audio output port of equipment such as television set, sound equipment is to the wireless connections that receive between earphone.
Along with emerging in a large number of the mobile phone with Bluetooth stereo function, also more and more widely for the application of bluetooth cellular phone wireless technology.With reference to CN200410081205.3, this patent is used to realize the mobile phone of bluetooth communication function and the wireless telecommunications between the bluetooth earphone, realize the wireless transmission of the audio signal between audio frequency apparatus and the bluetooth earphone, it has adopted independently system, be not integrated in the mobile phone, can only adopt bluetooth synchronous link (SCO link) transmission PCM (pulse code modulation) code signal, therefore limit to its transmittability.On the other hand, in this patent, scheme provides support if audio output apparatus such as the other side's mobile phone or TV do not have specially for this reason, then can't realize control interface function and effectively mutual communication mechanism, because itself only be the bluetooth module that has the PCM codec chip, and control problem such as how to open, how to close, how to power and how to switch all can't solve.
Summary of the invention
The objective of the invention is to change, realize the function of ordinary audio earphone by the part of bluetooth cellular phone being carried out on circuit and the software.Particularly, install the audio frequency incoming line on bluetooth cellular phone additional, then all have the equipment of audio output interface, for example television set, sound equipment or host computer, all can send wireless audio signal to the bluetooth earphone end, thereby realize the ANTENN AUDIO ear-phone function by the blue-tooth device of mobile phone.
For achieving the above object, the invention provides the bluetooth cellular phone that can serve as wireless audio output earphone, its characteristics are, this mobile phone comprises and is installed on the audio frequency incoming line that is used to connect the equipment that has audio output interface on the mobile phone, is installed on the analog to digital converter that is used for audio analog signals is converted to digital signal on the mobile phone.
Above-mentioned mobile phone, its characteristics are, also comprise Bluetooth chip, and pulse code modulation interface or packet data interface by Bluetooth chip send described digital audio and video signals to bluetooth earphone.
Above-mentioned mobile phone, its characteristics are that the digital audio and video signals that is sent by mobile phone comprises voice signal and note signal.
Above-mentioned mobile phone, its characteristics are that described voice signal is by the transmission of coded modulation interface, and described note signal is transmitted by packet data interface.
Above-mentioned mobile phone, its characteristics are that mobile phone can in time switch to call mode when incoming call.
Technique effect of the present invention is: applicable to any occasion that needs to use the ANTENN AUDIO earphone, substitute the ANTENN AUDIO earphone comprehensively, and easy to carry quick, need not other redundant equipments.The present invention mainly transforms and a little is mobile phone, main purpose is the expansion of cell-phone function, because based on mobile phone is the basis research and development, therefore the inner strong multimedia coding/decoding capability (multimedia chip) of mobile phone and make by the higher-quality audio signal of ACL link (async link) transmission for the control ability of baseband communication (baseband chip) and to become possibility, promptly, can be by ACL link transmission bandwidth up to the audio signal more than the 44.1Khz (mp3 tonequality), simultaneously, the present invention can finish how opening of prior art existence smoothly by revising cell phone software, how to close, how to power and control problem such as how to switch.
Further describe specific embodiments of the invention below in conjunction with accompanying drawing.
Description of drawings
Figure 1 shows that system schematic of the present invention;
Figure 2 shows that entire system block diagram of the present invention;
Figure 3 shows that amended bluetooth cellular phone outside drawing according to the present invention.
Embodiment
Describe preferred implementation of the present invention now in detail, embodiment is shown in the drawings.As much as possible, in whole accompanying drawing, use same Reference numeral to represent identical or similar parts.
Figure 1 shows that system schematic of the present invention.As shown in Figure 1, this system schematic comprises television set 10, mobile phone 11, bluetooth earphone 12 and tone frequency channel wire 13.Certainly the electric type product that has the analogue audio frequency delivery outlet here is not limited to television set, can also be all equipment that has audio output interface, for example sound equipment or main frames etc.With reference to Fig. 1, by tone frequency channel wire 13 audio output interface of television set 10 is connected to AD translation interface (analog-to-digital conversion interface) on the mobile phone, this AD converter is converted to digital audio and video signals with simulated audio signal, and sends this audio signal by the pcm interface or the packet data interface of Bluetooth chip to bluetooth earphone 12.
Figure 2 shows that entire system block diagram of the present invention.According to Fig. 2, this entire system block diagram is made up of three parts as can be seen, and first is an electrical equipment audio output interface 20, and second portion is the mobile phone part, this part is made of audio A 21, mobile phone MPU (microprocessing unit) 22 and bluetooth module 23, and third part is a bluetooth earphone 12.This system block diagram has reflected the transmission of audio signals process more intuitively, promptly, electrical equipment audio output interface 20 output simulated audio signals, receive this simulated audio signal by bluetooth cellular phone by carrying standard audio data wire 13, and this simulated audio signal is converted to digital audio and video signals by being arranged at bluetooth cellular phone sound intermediate frequency AD21, after handling, mobile phone MPU22 is sent to Bluetooth transmission module 23, and realize the digital audios transmission with bluetooth earphone 12 several meters away, revert to normal sound by I tech clip S 12 again and play, thereby realize the process that whole digital audio transmits.
Figure 3 shows that amended bluetooth cellular phone outside drawing according to the present invention.As shown in Figure 3, this carries standard audio line 13 and includes but not limited to be arranged at this position.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all contained by claim of the present invention.
