Mutual Speaker Product Function Description
Mutual inductonic audio uses current mutual inductance technology, no Bluetooth, and link audio cable, just put your phone in the sound, you can achieve audio functions!
· Magic amplifies the audio of equipment such as mobile phones.
· There is no need for any pairing settings.
· automatic switch.
· Most IOS devices and Android mobile phone support.
· Strong output: 2W * 2RMS.
· Efficient - 15 hours of broadcast time * aa alkaline battery x3.
• Low electric display.
· Support audio input (3.5mm) and DC input (data cable) socket.
· Products include: speaker * 1
.operate:
1 mobile phone and other playback equipment:
• When in standby or boot mode, put the device such as an external speaker such as an iPhone in the correct direction, and the external speaker or audio is playing, you can start the product function to realize the sound function. The iPhone4 alignment can realize the sound function.
· Different audio devices are set, and they will try to visit the equipment until it is consistent with the speaker sensor (the induction area of the product is two points on the left and right sides of the front end, as long as your external speaker is aligned with a local level).
2 Volume adjustment: To adjust the volume, simply change the volume of the phone, the speaker automatically adjusts the output volume.
3 Audio in the operation: The socket of the diameter of 3.5mm is the wired audio of most mobile phones, input settings, and the use of wiring mode can be better than the bass playback.
4 Power: This mini audio can be powered by 3 AA batteries or external data cable sockets. The speaker will remain in the default standby mode when the battery is placed.
· Each time the power button is pressed, the power status will be further: shutdown --- Standby --- boot --- shutdown ...
5 automatic boot / shutdown:
· When the product is in standby mode, if the music is placed in the correct position, the product will start automatically.
· After 1 minute, the product will return to standby mode. If the alkaline battery is used, the product can remain in standby 6 months.
· When in power-on mode, the product will automatically shut down after 10 minutes of music.
6 Low power display: Blue indicator flashes 3 times a 4 seconds represents insufficient power. Only in standby mode is displayed.
· Please note: When the battery is low, the high volume playback may make the sound distortion.
• When the amount of power is relatively low, the system automatically cut off the power to place the battery damage.
7 External 5V DC input: The data cable jack can be used for 5V DC external power supply. When the external power is inserted, the AA battery will not be used.

Circular principle Description:
Simply, it is a mobile phone and other equipment to play music, the speaker generates a magnetic field, and the transformer converts the magnetic field into current and then enlarges the drive speaker through the power amplifier IC. The circuit mainly has MCU, audio amplification IC composition.
The MCU is mainly used to control the detection of switching, current and audio signals, and amplifier ICs are used to enlarge audio signals.
