1, mainly 32 computing power is relatively strong, after all, it is a 32-bit low-power chip, convenient data processing operations, and peripherals similar to 51, more, low cost. The 8bit of 51 is more successful, and the general industrial control applications can be dealt with, and it is a little difficult to deal with when the amount of computation is large.
2, the entry commonly used intelligent car, the chip is usually used 8-bit single-chip microcomputer. Foreign countries use Microchip PIC microcontroller more, domestic AtmelThe market is doing better, using AVR more. Further, you can consider using stm32 series microcontroller.
3, the toy electric vehicle control chip is a high-voltage battery-powered step-down DC-DC power management chip, which integrates the reference power supply, oscillator, error amplifier, current limiting protection, short circuit protection and other functions.
4, radio frequency receiver: Radio frequency receiver is the "ear" of smart cars. Radio frequency device is an important part of wireless communication. Radio frequency is an electromagnetic frequency that can radiate into space, and the frequency range is between 300KHz and 300GHz.
2, the voice chip refers to the IC that can store and control the playback of voice, also known as the sound chip, audio ic. According to the output mode of the voice chip can be divided into two categories, one is PWM output mode, the other is DAC output mode.3, speech chip definition: the speech signal is converted into a number by sampling, stored in the IC ROM, and then through the circuit to restore the numbers in the ROM into a speech signal.
4. Add audio to greeting cards, movie posters or advertisements. Emergency plans: OTP voice chips can be used for emergency plans, such as fire alarms and oxygen alarmsWare and wait. In short, the wide application of OTP voice chip lies in its characteristics of high stability, high-quality sound, low power consumption and cost economy, which can be flexibly set according to application needs.
5, low power speech recognition chip has: recognition accuracy is unstable, limited processing capacity and other shortcomings. Unstable recognition accuracy: In the case of low power consumption, the accuracy of the speech recognition chip may be affected and unstable.
6, Ω/ 1w or 8Ω/ 2w horn chips can also be driven.
Gain insight in the game. MP3 chip can be embedded with educational audio content, support infrared remote input and external audio input function; Promote children in the game to learn knowledge, increase insight.
In addition, in the field of smart home, voice recognition technology has also been widely used, smart speakers can control home appliances through voice commands, to achieve the construction of smart home scenes. In addition, voice recognition technology can also be used for voice search, telephone customer service and so onDomain.
Smart home control: control the lights, appliances, curtains and other equipment at home through voice commands to improve the convenience and intelligence of the home. Voice Assistant: such as Siri, Google Assistant, etc., they can understand and execute the user's voice commands, information query, schedule management, set reminders, etc.
AI chips can help speech recognition systems better recognize speech signals and convert them into words or actual actions. Smart home field Smart home has become an indispensable part of people's lives, and AI chipsApplications are also making smart homes smarter.
Intelligent toys are currently showing three advantages: content: intelligent toys implant educational video and audio (music, stories, pictures, etc.), fully develop imagination and creativity. There are also some task-based smart toys that interact with children through speech recognition to enhance children's behavioral and cognitive skills.
Scenarios that voice recognition can be applied to: Compared with traditional control and interaction forms, the use of voice interaction in the field of smart home will be more convenient for users. Amazon, Google, Baidu, XiaomiAlibaba and other enterprises have released their own smart speaker products.
1, the music chip is divided into recordable and unrecordable, and the recordable chip can record the human voice to the chip through the circuit, and then play it out through the circuit. Such as music toy boxes, phonographs, outside often heard vendors Shouting are made of a recortable chip.
2, prepare tools and materials: in addition to the lantern light bulb and chip, you also need a small screwdriver and some cables. playSmall light bulb: Usually the light bulb has a screw or similar connection device.
3, record the pitch, length, two parameters can play the music, if complex, record the volume. Music playback is completed by the music synthesis chip, there are generally two ways, FM synthesis, wave table synthesis.
4, through the import method. The music is imported into the software that controls the robot, and then transferred to the intelligent memory chip inside the robot, and the music is imported into the robot. Intelligent robot is called intelligent robot because it has a rather developed "brain".
Speech chip definition: the speech signal is converted into a number by sampling, stored in the ROM of the IC, and then through the circuit to restore the numbers in the ROM into a speech signal.
The most common words are used to regulate the playing and receiving of sound. For example, your own mp4, here the most important is the audio decoding chip and video decoding chip and memory chip if you want to put the first call memory chip data through the audio decoding coreWe need to process it to get it out.
Drive him around with a toy motor. Intelligent toys are a new generation of high-tech early education toys, and the Zhiduo Bear early education intelligent toys produced by Chuang Wise Company are typical representatives in this respect.
Offline speech recognition chip is an integrated circuit that can recognize speech locally in the device. Unlike traditional speech recognition systems that rely on cloud servers for processing, offline speech recognition chips have the ability to recognize speech inside the device.
Interactivity: Voice recognition chips can allow smart toys to interact more naturally and directly with children, so as to better enhance children's communication and social skills. Educational: Smart toys equipped with speech recognition chips can help children conduct independent learning and language training, thereby improving their language expression and understanding.
The music chip is divided into recordable and unrecordable, and the recordable chip can record the voice of the person to the chip through the circuit, and then play it out through the circuit. Such as music toy box, phonograph, outside often heard hawker Shouting are recordedIt's made of chips.
Adjusting the volume can be solved by adjusting the magnification of the amplifier triode (generally 9013) connected to the back of the chip, and can also be solved by changing the resistance in series, changing the voltage, etc.
