The audible device 300 has a control unit 3, a display unit η, an audio processing unit 32 > 5 - , χ, ss - 兀 兀 and 丨 兀 , 33, and the control unit 3 协调 is used to coordinate the components and identify The transmission signal 102 from the (10) playback device, and the audio processing unit 32 plays and outputs to the sound reinforcement device_playing; the interface unit 70 33 can obtain the transmission signal 102 from the connector 331 for the control unit 30 to use or self-connect. 331 output control unit 3 传输 transmission signal ^. The peripheral device 100 has a 'first interface 11, an i-input', a first; an I-side 12 and a conversion circuit 13 in addition to the aforementioned body and connectors (1), (2); The second interface 12 is electrically connected to the audio device; the conversion circuit 13 is electrically connected between the first interface u and the second terminal 2 to receive the iP〇d playback device. The transmission signal 101 of 1295647 is converted into a transmission signal 102 that can be recognized and used by the audio device 300, or the transmission signal 1〇2 of the audio device 300 is received and converted into a transmission signal 1 that can be recognized and used by the iPod playback device 200. 〇1. Referring to FIG. 2 and FIG. 3, the conversion circuit 13 includes a power supply unit 131, a conversion unit 132, an amplification unit 133, and a connection line 134 bridged between the first interface 11 and the second interface 12, and the first interface. The definitions of the pins of η and second interface 12 are shown in Table 1 and Table 2, respectively. Table 1 Pin No. Definition 1 F/W Ground (F/W GND) 2 F/W Ground (F/W GND) 11 —--- F/W Positive power supply (F/W PWR+) —12 F/W Positive power supply (F/W PWR+) One 13 power supply (PWR; 3.3 V) 18 Transmission (TX) 19 Receive (RX) _ 27 Left Channel (Audio line L) _ 28 Right channel (Audio line R) 29 Ground (Audio GND) s 30 Event notification (EVENT) Table 2 1 pin number definition _ 1 Digital ground (D GND) ^^2_ Power supply (ACC 5 V) _ 3 Event Notification (EVENT) _ Remote Control/Transmission (REMO/TX) __ 6 Analog Ground (A GND) 7 Data/Receive (DATA/RX) s10 Left Channel (L CH) 13 Right Sound Road (R CH) 8 1295647 Referring to Figs. 2 and 3, when the connectors ill, 121 of the peripheral device 1 are connected to the connector 241 of the iPod playback device 200 and the connection state 331 of the audio device 3, respectively, 丨! > 〇 (1 playback device 2, ie, a notification signal 401 is sent through the connection line 134 for the audio device 3 to detect that the ip 〇 playback device 200 is connected.
