IC is short for "integrated circuit", also known as integrated block, audio ic is the integrated circuit for audio.
Audio IC is an integrated circuit used in audio products, such as an integrated circuit used for digital-to-analog conversion, sound processing, and power amplification; The power supply IC is electricitySource voltage regulator, DC/DC converter, etc. used to control the output voltage and current of the integrated circuit.
IC is short for integrated circuit block, subwoofer IC, is the audio integration block used by subwoofer. A subwoofer is a horn that only has a bass, no mid-treble, and cannot be used alone. Two satellite speakers are required. 1 sound, is a subwoofer, with two satellite speakers, can not say that it is a subwoofer, is a sound.
IC is the abbreviation of integrated circuit chip, which refers to the integrated block of power amplifier.
Audio power amplifier IC, referred to as: soundThe formula is correct, and the amount of written data is appropriate.
2, for example, the ISD series of voice chips, some chips with MIC interface, connected to the electret microphone, press the recording key, the sound is recorded in, record a paragraph or all stop. There is also an external voice memory, which can be used to input the sound with the chip, or the sound data can be stored in advance through the external MCU, and then the chip can be played according to the set address information.
3, the language chip, as the name suggests, is the IC that can store and control the playback of speech. It refers to the conversion of speech signals through sampling intoThe numbers are stored in the ROM of the IC, and then the numbers in the ROM are restored to the voice signal through the circuit. From the point of view of use, the main way to use the voice chip is to record it first, and then use it after the recording is completed.
4, this is embedded in the music chip, music chip is a relatively simple voice circuit, it through the internal oscillation circuit, and then a small amount of discrete components, you can produce a variety of music signals, music chip is an important branch of the voice integrated circuit, Widely used in music electronic greeting cards, electronic toys, music candles, electronic clocks, electronic doorbells, household appliancesAnd other occasions.
5, the voice chip and the MCU are two different chips, but they have a close relationship. This paper will deeply discuss the relationship between voice chip and single chip microcomputer to help readers better understand the characteristics and applications of these two chips. Voice chip: The realization of digital magic A voice chip is a chip with a special function that converts our voices into numbers and is stored in a small IC. Through clever circuitry, these numbers are restored to a beautiful sound.
6, speech chip definition: the voice signal is converted into a number through sampling, stored in the RO of the ICM, and then through the circuit to restore the ROM numbers into speech signals. The playback function of the ordinary voice chip is essentially a DAC process, while the ADC process data is completed by the computer, including the sampling, compression, EQ and other processing of the speech signal.
Electronic module is usually composed of a variety of IC with a certain function of the device or integrated circuit board, a wide range, followed by IC, integrated circuit and finally mcu. Difference 2, do it differentlyYes. Large systems usually consist of many modules. The main products are IC driver external devices and other industrial products. The integrated circuit consists of a single chip computer and other electronic chips. Distinguish between different process requirements.
The scope of electrical products do not use electronic modules are usually composed of a variety of ics with a certain function of the device or integrated circuit board, a wide range, followed by IC, integrated circuit and finally mcu. Different large-scale systems are generally composed of many modules, IC mainly finished products to drive external equipment industrial products, etc., IC is composed of mcu and other electronic chips.
[tube power amplifier], "stone machine" [transistor power amplifier], "IC power amplifier" [integrated circuit power amplifier]. In recent years, due to the use of new technologies and new concepts in the bile machine, the vacuum tube, an ancient vacuum device, has shone, and its beautiful sound has made many burn friends bow down. Almost every veteran enthusiast has one. "IC amplifier" Because his timbre is not as good as the two amplifiers, he rarely sees his shadow in the HI-FI amplifier.
Voice IC and voice chip are the same meaning, but the name is different. OTP is a kind of voice chip. The voice chip of OTP uses one-time programmable (OTP) memory as the storage medium of voice information. Once data is stored in OTP memory, it cannot be modified or updated; Has unmodifiable properties.
Voice chip refers to the IC that can store and control the playback of voice, also known as 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. PWM output toneThe amount is not continuous and adjustable, can not be connected to ordinary power amplifier, most of the voice chips on the market are PWM output mode. Generally used in smart home and security fields such as smart doorbell, alarm and other products.
In the current era of advanced science and technology, integrated circuit is an indispensable component to promote the development of science and technology. The voice chip, as the name suggests, is an IC that can store and control the playback of speech.
1, audio decoding chip is different, audio function Jerry coreThe pieces are different. Audio decoding chip: Apple's audio converter ic chip, supporting the new system, decoding ear playback, audio otg and other functions. There is also the audio decoding chip LAM Apple Headset/Apple adapter chip, which is suitable for Apple headphones and has a high re-purchase rate.
2, the Snapdragon 710 adopts the same second-generation 10nmLPP manufacturing process as the Snapdragon 845, and the CPU part adopts the Kryo360CPU architecture. Performance core 6 Efficiency core (2 large core 6 small core design), the maximum main frequency of the large core 2GHz, the maximum main frequency of the small core 7GHz; Snapdragon 710GPU uses Adreno616.
3, the iPhone 5 audio decoding compared to the iPhone 4 uses a new Cirrus chip for Apple 338S1077. The iphone5's sound quality is not the best among Apple devices, Apple's best sound quality is the iphone5s and above. The iPhone 5s has changed the number of the CODEC and ClassD chips, but it still sounds closer to the iPhone 5, with almost no difference.
