Smart speakers can be used to sell consumer electronics in low prices, in the process of smart home and the Internet will become a general trend, such products are enough to enjoys the fun of artificial intelligence in advance at a lower price. 360 with Internet Corporation has already made a small layout in smart home, launched a variety of smart home products. However, as a smart speaker in the control center, the pace of 360 seems to be slower, before it is only launched a product named 咚咚 speaker A1.
360 The smart speaker launched by his own brand is not only in intelligence, but also brings an immersive experience in terms of sound. Next, I love Xi Internet Network to learn about this product through dismantling.
First, 360 AI speaker unpacking
The packaging is a simple traditional audio package design style, 360 smart speaker's packaging front partial part with speaker pictures, the upper left corner writes the model "M1 360AI Speaker" word
Behind the packaging is the product details.
On the right side of the box, the black background is used, which writes a massive content and skills service, QQ music, cool dog music, cool music can be available at any time; Himalaya, listening to the head, 蜓 FM, lazy people listen to books, etc. If you want to listen, there are children commonly used pocket stories, baby bus, rabbit baby, and June 1 children's network should have.
The package includes product body, power adapter and instructions.
Power adapter close-up, line and charger are integrated.
The power adapter output interface is the DC circle.
360 Power Adapter, Model: TEKA018-1201500CH, input: 100-240V ~ 50 / 60Hz 0.5a max.
The front of the speaker is a dustproof net of the speaker.
The back is a DC power input.
The top of the product is divided into two parts, and the upper half is 360 logo and four microphone pickup holes, the following is the buttons.

The whole speaker is a tough traditional Bluetooth speaker shape, and the four sides are more round than the general rectangle.
There is a long plastic blending pad on both sides of the bottom.
Product Name: 360AI Speaker, Model: 360-M1, Enter: DC12V 1.5A, Shenzhen Qihu Intelligent Technology Co., Ltd., China Manufacturing.
Second, 360 AI speaker dismantling
Open the mask of the speaker, there are two low-frequency vapor films and a full-range speaker.
The front mask of the speaker is a non-woven dustproof net, and there is a sponge to reinforce fixed.
To look at the front of the speaker, there are multiple screws to fix.
Unpacking the front, the internal speaker occupies the main space, and the remaining position will leave the sound to form a sound cavity and enhance the bass effect.

Trumpet impedance 4Ω, model RR MS F3.
The power board is fixed in the fuselage and connects the cable to the top of the top.
Remove the screws of the fixed power board, the front side of the power board has a DC circle input socket, two electrolytic capacitors and two ferrite inductance.
The buttons located on the top of the speaker are fixed with glue. Directly torn, you can see that the following baffles are fixed with screws, and the lower layer has four micro-motion buttons.
Remove the top button module.
The glue is fixed from the wire from the fuselage.
Turning into the back, take a closer look, use so many frames to protect, this piece may be a motherboard.
Unpack metal protection frame, there is a motherboard and a piece of panel.
Back view of the plastic protector of the keyboard.
The microphone plate on the sub-board, four microphones are protected by black silicone sleeves, and the small plate is connected to the motherboard.
There is a sponge pad on the back of the small plate, alleviating the vibration between the housing.
Torn one of the silica gel sleeves, protected is a MEMS silicone, laser engraving is 3003 8C22.
Speaker motherboard positive close-up.
The top floor of the motherboard is designed with 4 tap buttons, with 5 RGB three-color LEDs, a total of 15 LED channels match the LED driver chip AW9523B interface. The white radial area on the PCB board is to increase the reflection brightness of the LED.

Onboard antennas located on the edge of the motherboard.
A LED indicator, a radial coated area enhances the light reflection.
The IC of the silk screen JWA5J 81B1Q.
Silk screen JWK7J 8MB8E IC.
AWINIC AW9523B, this is an I2C interface that supports LED driver chips for 16 breathing lights. The 16-way LED is a common-active low pressure reduction constant current drive, and each path has 256 step-line dimming function.
Realtek Rui Rui RTL8723DS Bluetooth + WiFi two-in-one control IC, supporting 150M 2.4G WiFi, in line with IEEE 802.11b / g / n / i / e standard; Bluetooth, complies with Bluetooth 2.2 + EDR and Bluetooth 4.2 requirements. Backward compatibility BLE4.0.
Gigadevice fp1849 5f1cq4yubyig 1Gbit Nand Flash.
Rockid kamin018. This is an AI voice-specific SOC chip, built-in ARM CPU, DSP, DAC, etc. Intelligent speaker essential components, which brings quite high integration. The four pickup microphones at the top of the high-performance ADC can provide users with an excellent voice awakening experience.
The front of the power board is close-up, with a DC round port input, a Micro USB interface, two electrolytic capacitors, and two ferrite inductance.
Back side of power board.
DC round port input terminal and Micro USB socket.
SS24 Schottky diode.
70μF 25V green capacitance acts as a filtering.
The amplifier chip is Ti Texas Instrument TAS5805MA, which is a high-efficiency stereo closed-loop D amplifier chip, the maximum power support 23 W, supports multi-band advanced DRC and AGL.
Decomposition of the whole family blessing.
Third, I love sound network dismantling summary
1. Use independent small board to place audio amplifier circuit, which can reduce interference, bring better sound quality;
2, using large-size speakers and two passive radiating films, good audio effects;
3, the keyboard uses multiple RGB LED lights to bring a good visual effect.
