本发明涉及一种音乐装置，特别是涉及一种有线或无线的耳机或音箱共享音乐的装置。The invention relates to a music device, in particular to a device for sharing music with wired or wireless earphones or sound boxes.
背景技术Background technique
目前无线电耳机采用的无线电技术有：Bluetooth，wifi，Zegbee，NFC，FM，GFSK，红外线，磁力线，及其它无线技术。都有发射及接收端。发射端接上音源，经处理及调制段发射到空中，一部或多部接收端各自收到后解调及处理后把该音源还原，经喇叭播出。用家接收发射端模式：①、一发射端对一接收端；或②、广播式接收，即一发射端对多个接收端。The radio technologies currently used in wireless headsets include: Bluetooth, wifi, Zegbee, NFC, FM, GFSK, infrared, magnetic lines, and other wireless technologies. There are transmitters and receivers. The transmitting end is connected to the sound source, and after processing and modulation, it is transmitted into the air. After receiving it, one or more receiving ends demodulate and process the sound source to restore the sound source, and broadcast it through the speaker. The user receives the transmitter mode: ①, one transmitter to one receiver; or ②, broadcast reception, that is, one transmitter to multiple receivers.
问题是：当甲乙两人一起听同一首音乐/歌曲时，一般采用无线广播模式，即一发射端，可配多个接受端，但当两人一起各自听音乐/歌曲时，在当时想同时分享对方的同一音乐/歌曲，需把对方的播放器或耳机和对方对换，或在对方播放器并联多一个插头，对方才能听到该音乐/歌曲。非常不便。研究①发现，在接收端内再加上一组发射端，并新设一档为主动（MASTER）/从动（SLAVE）档供用家设置该共享模式。例：甲方设置为主（MASTER），乙方设置为从（SLAVE）模式，甲方耳机内接收端收到播放器传来的音乐/歌曲，经甲方发射端传送到乙方接收端播放出该音乐/歌曲。研究②发现：播放器传送音乐到主甲方（MASTER），再由甲方把此音源调制后经人体传送该调制信号，通过和乙方身体接触如牵手把信号从甲方通过人体传到乙方耳机内接收端进行解调及处理后从喇叭播出该音源。但由于从人身传送过程中，产生了噪声及噪音，此噪声及噪音不易解决。为解决此问题。从甲方通过人体传到乙方只传递控制音乐开关信号及配对码信号。不传递音乐信号。这解决了传递过程中噪音问题。而音乐传播仍用无线电方式从空中传递。The problem is: when A and B listen to the same music/song together, they generally use the wireless broadcast mode, that is, one transmitter can be equipped with multiple receivers, but when they listen to the music/song together, they want to simultaneously To share the same music/song of the other party, you need to exchange the other party's player or earphone with the other party, or connect an extra plug in parallel with the other party's player, so that the other party can hear the music/song. Very inconvenient. Research ① found that a group of transmitters is added to the receiver, and a new file is set as the master (MASTER)/slave (SLAVE) file for users to set the sharing mode. Example: Party A is set to master (MASTER), and Party B is set to slave (SLAVE) mode. The receiving end of Party A’s earphone receives the music/song from the player, and transmits it to Party B’s receiving end through Party A’s transmitting end to play the music/song. music/song. Research ② found that: the player transmits music to the master Party A (MASTER), and then Party A modulates the sound source and transmits the modulated signal through the human body, and through physical contact with Party B, such as holding hands, the signal is transmitted from Party A through the human body to Party B's earphones After demodulation and processing by the internal receiving end, the audio source is broadcast from the speaker. However, due to the noise and noise generated during the transmission from the human body, the noise and noise are not easy to solve. To solve this problem. From Party A to Party B through the human body, only the control music switch signal and the pairing code signal are transmitted. Music signals are not passed on. This solves the problem of noise during transfer. And music transmission is still transmitted from the air by radio.

具体实施方式detailed description
为能进一步了解本发明的特征、技术手段以及所达到的具体目的、功能，下面结合附图与具体实施方式对本发明作进一步详细描述。In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
首先，附图5为一个具体实施例的原理图，分为甲、乙两人的第一播音装置A1（耳机或音箱）、第二播音装置A2（耳机或音箱），第一播音装置A1和第二播音装置A2原理图一样，音乐播放器用蓝牙无线传送或有线连接到第一播音装置A1（耳机或音箱），甲配带的第一播音装置A1（耳机或音箱）带第一无线电收发线路模块100（Wireless Transceiver Module），第一无线电收发线路模块100发出调制无线电波，发射到乙配带第二播音装置A2（耳机或音箱）内的第二无线电收发线路模块200（Wireless Transceiver Module）接收，第二无线电收发线路模块并同时进行解调，还原出音乐讯号，由于在第二播音装置A2设置了第二静音控制电路201，此时音乐被静音，直至由第一播音装置A1的第一微电脑控制单元110（MCU）产生静音控制讯号，进入第一发射调制器112（Modulator）的“TXDATA”端，本案例经调制及高频振动器Q4、X2、Q2、产生2.3MHZ载波频率信号，经Q5、Q6放大后经U5SPDT SWITCH再由第一耦合天线111（Coupling antenna）发射出去，该2.3MHZ载波信号直接发射到人体上，而且信号比较弱，信号到人体后，人体为导体天线，该2.3MHZ载波信号沿着甲人体表面向四周爬行，通过乙人体表面的任何位置有效接收信号，信号耦合进入乙第二播音装置A2接收端的第二耦合天线211而接收信号，同样地，近距离靠近或接触可做到直接由A1进入A2耦合天线效果。该讯号经U5SPDT SWITCH进入第二接收解调器214（Demodulator）的Q1混频放大器，经IC1解调后返原输出控制信号RX_DATA进入第二微电脑控制单元210（MCU）单片机U3，U3核对讯号码正确后输出控制电平经BT_RXD通知第二无线电收发线路模块200，由第二无线电收发线路模块200输出一电平把第二静音控制电路201（静音控制系统）SHDN引脚打开，此时第二音频功放203（Power AMP）推动第二播音单元204（喇叭）播出。At first, accompanying drawing 5 is the schematic diagram of a specific embodiment, is divided into the first broadcasting device A1 (earphone or sound box) of two people of A and B, the second broadcasting device A2 (earphone or sound box), the first broadcasting device A1 and The principle diagram of the second broadcasting device A2 is the same, the music player is connected to the first broadcasting device A1 (headphone or speaker) through Bluetooth wireless transmission or wired connection, and the first broadcasting device A1 (headphone or speaker) equipped with A has the first radio transceiver line Module 100 (Wireless Transceiver Module), the first wireless transceiver circuit module 100 sends out modulated radio waves, which are transmitted to the second wireless transceiver circuit module 200 (Wireless Transceiver Module) in the second broadcasting device A2 (headphone or speaker) of B for receiving , the second radio transceiver circuit module demodulates at the same time, restores the music signal, because the second mute control circuit 201 is set at the second broadcasting device A2, the music is muted until the first broadcasting device A1 The microcomputer control unit 110 (MCU) generates a mute control signal, which enters the "TXDATA" terminal of the first transmitting modulator 112 (Modulator). In this case, the modulated and high-frequency oscillators Q4, X2, and Q2 generate a 2.3MHZ carrier frequency signal. After being amplified by Q5 and Q6, it is transmitted by the first coupling antenna 111 (Coupling antenna) through U5SPDT SWITCH. The 2.3MHZ carrier signal is directly transmitted to the human body, and the signal is relatively weak. After the signal reaches the human body, the human body is a conductor antenna. The 2.3MHZ carrier signal crawls around along the surface of A's human body, effectively receives the signal through any position on the surface of B's human body, and the signal is coupled into the second coupling antenna 211 at the receiving end of B's second broadcasting device A2 to receive the signal. Similarly, close proximity Or contact can achieve the effect of coupling antenna directly from A1 to A2. The signal enters the Q1 mixing amplifier of the second receiving demodulator 214 (Demodulator) through U5SPDT SWITCH, and returns to the original output control signal RX_DATA after being demodulated by IC1, and enters the second microcomputer control unit 210 (MCU) MCU U3, and U3 checks the signal number After being correct, the output control level is notified to the second radio transceiver circuit module 200 via BT_RXD, and a level is output by the second radio transceiver circuit module 200 to open the SHDN pin of the second mute control circuit 201 (silence control system). The audio power amplifier 203 (Power AMP) drives the second broadcast unit 204 (speaker) to broadcast.
