In the spring of 2019, a small family of a small family-small is available at home, 329 yuan, and higher cost performance. For users who pay more attention to cost-effective, I am a nice new choice at home. Because it makes it possible to maximize cost performance in the case where the core function is basically unchanged.
What kind of secrets have been hidden in the end of the performance of the performance? I love Xi Fang immediately announced by dismantling.
First, small at home 1s out of the box
The push is a fresh light background and wallpaper in the product. Above the product name: Small home 1s smart home assistant at home.
Product Name Small at Home 1S Smart Family Assistant, Product Model: NV6001, Enter: 12V 2A, Producer: Beijing Baidu Net News Technology Co., Ltd., Manufacturer: Beijing Little Fish Network Technology Co., Ltd.
On the other side, more than ten items it supported (official data update: more than 1,000 skills have been supported).
The packaging is designed with a heaven and earth cover, and you can see the product body. There is a film on the screen, "" I said that 'Xiao Dao' open smart life ", users can know his voice command.
After taking out the product, the following is a layer of PET, the next layer is some accessories.
The package contains product body, power adapter and instructions.
The power adapter uses the DC circle output.
Power adapter model: CYZS24-120200C, input 100-240V ~ 50 / 60Hz 0.6A, output: 12V 2A.
After torn open the film, you can see the black screen, the above front camera and the lower half of the speaker, the design is simple and generous.
Side speaker holes for low frequency output.
The upper half of the back is relatively simple, is a small logo, and the lower half is a low frequency output hole, a power line hole of the bottom of the data interface of the cover protection.
You can see a Micro USB interface with fine clearance.
There are some round holes on the top, used to make the sound to the microphone, the middle is a power button, arranged neat, which is conducive to sound conveying.
The bottom has anti-slip strips and information nameplates and power input ports, and the slider can effectively bring stable support for the product.
Small at home 1s smart family assistant China Manufacturing Production: Beijing Baidu Network News Technology Co., Ltd., Manufacturer: Beijing Xiaoyi Network Technology Co., Ltd., Model: NV6001, Enter: 12V 2A.
The effect diagram after booting, it looks from the side. This is unique at home 1s, and the front and back is designed with neat circular holes, ensuring music, and sound effects.
Second, small at home 1s dismantle
Next, a disassembly is started, torn down the bottom of the non-slip strip, you can see four screw holes.
Start to remove the cross screw.
The cover of the speaker is disassembled, see the main board and speaker cavity of the product to be fixed, such design, effectively utilized the space.
The motherboard is fixed to the back of the face, and there is a black metal shield cover above.
The speaker module is fixed by four screws, and each screw bit has added a damping rubber ring, and the process is fine.
The Bluetooth antenna is welded to the main wire of the motherboard.
The cover is below the acoustic hole of the speaker, and there is dustproof net protection in the inside to prevent dust.
Remove the black shield on the motherboard, which is silver.
The motherboard is close-up, there are three metal masks above.
Metal heat sink on the back of the motherboard.
In addition, there is no other component on the back of the motherboard, only a few heat dissipation regions.
Some solid capacitors and inductors on the motherboard.
There are two wire printing T12 003 IC under the row socket.
Ti Texas Instrument TPA3110D2 15W No filter D Class DC Amplifier.
SGM Holy SGM6132 DC-DC, the input limit voltage is 31V, the output current is 3A, with high pressure, high current, and cost performance.
Silk print B219G IC.
Silk screen SS34
Next, the second layer of metal cover is removed.
With the following frame, you can see the frontside of the motherboard.
Sec S Samsung Electronics KLM8G1GETF-B041 8GB EMMC memory chip for storing products and other data.
MTK Liaotai MT6357V Power Management IC, designed for smart device, including 5 converters and 29 LDOs, using SPI interfaces and two SRCLken control pins to control BUCK converters, LDOs, and various drivers, it provides enhancements Safety control and agreement with BB handshake.
BIWIN BW52L256M32D1PF Cache IC.
MTK Liaotai MT8765V processor, built-in 4X ARM Cortex-A53 MPCORE quad-core processor.
MTK Lianfa MT6625L connection chip, including 2.4GHz Wi-Fi / Bluetooth transceiver front end, 5 GHz Wi-Fi transceiver front end, GPS receiver front end and complete FM receiver.
The camera module is connected to the motherboard with a soft ribbon, and there is a QR Code sticker on the cable.
To see the speaker, it is a speaker with paper pot as a diaphragm. It can be seen that the size of this speaker is larger in the smart speaker.
The Tron is printed on the back of the Tie, and the terminal block is distributed on both sides.
You can see the bomb in the horn.
After removing the speaker cavity, there are two small plates connected to the back cover.
DC power input, using a cable connection.
A piece of heart-shaped PCB is fixed on the back of the top cover for functions such as button operation and microphone radio.
Remove this PCB and there is an IC, microphone, and micro-motion button.
X-Power Core III AC108 ADC. It is a high-performance four-channel data converter ADC, mainly used in smart voice far field microphone array pickup, up to 100-channel microphone, SNR is 108dB.
Microphone close-up in the top of the product, is used to pick up the voice of the user's voice instructions and video calls.
The micro-click close-up, the following is printed with the Power word, indicating that this is the power button.
The power input is a Micro USB interface on the back of the board. It is speculated that the manufacturer performs data update interfaces.
Circle DC DC power socket.
The IC of the silk screen T12 003.
The speaker's wire is wrapped in a sponge, which can reduce the noise generated within the cavity.
Passive low-frequency vapor film on the side of the speaker chamber.
On the other side, there is also a passive low-frequency vapor film, which can be seen that the 1s smart speaker at home is a combination of large-sized full-range speakers and passive low-frequency vapor films. It belongs to a relatively rich configuration in the smart speaker. It can bring more nice. Listening experience.
Wire socket close-up, this wire is used to output the motherboard to the speaker.
Decomposition of the whole family blessing.
Third, I love sound network dismantling summary
1, small at home 1s with screen smart speakers, unique design, with large screens and large-sized speakers, while both independent sound cavity;
2, built-in MTK Union MT8765 processor, this is a high-performance quad-core processor with powerful video performance and speech processing performance;
3. The 3 microphone is used to form a pickup array, which can clearly receive the voice command;
4, this smart speaker uses a combination of 1 full-frequency speaker and 2 passive low-frequency vapori, which uses this speaker combination in the smart speaker industry, and the product material has exceeded product pricing, so this small degree At home 1s has a higher cost performance.
