Audio Electronics deals with the circuits that are designed for converting sound/pressure wave signals to electrical signals, or vise versa. These circuits are used to processes and manipulate audio signals to design different types of audio amplifiers, audio mixers, frequency controllers etc..
This section consists of a huge collection of audio circuits with schematics and detailed explanation, to help you build Audio projects and use them for your Audio designs.
To help Bluetooth speaker and headphone manufacturers maintain product differentiation in the competitive wireless audio market, Microchip Technology released the next generation of its Bluetooth 5.0-qualified dual-mode audio IC and fully certified module.
Measuring just 5.5 x 5.5 mm, the low-power…
Chirp, a pioneer of data-over-sound technology and Linkplay Technology, a leader in Wi-Fi audio solutions have today announced a technical partnership, delivering a turnkey solution for the frictionless, audio-based provisioning of smart-enabled consumer applications. Leveraging Chirp’s ultrasonic audio protocol, smart-enabled devices integrated with Linkplay’s comprehensive…
Power Integrations announced that its 200 V Qspeed™ diodes – LQ10N200CQ and LQ20N200CQ – are now available with AEC-Q101 automotive qualification. Qspeed silicon diodes use merged-PIN technology to offer a unique balance of soft switching and low reverse recovery charge (Qrr). This results in low EMI and reduced output noise, which is especially important for in-…
Certification is usually one of the most expensive and tedious stages during the development of a new hardware product. It helps the authorities to know that the product adheres to all the laid down laws and guidelines around the functions. This way, the performance of that particular product can be assured to prevent hazards, and harm to its users. As tedious as this stage…
Text-to-speech or TTS system converts normal text into Speech. This tech enables the system to speak out the text in a human voice. There are many examples of Text to Speech conversions like the announcements at public transport, the customer care calls, voice assistants in your smartphones, or the navigation menu of any machine. You can even find the TTS in Microsoft Word…
Raspberry Pi is a palm sized computer having in-built Bluetooth, Wi-Fi, Ethernet port, Camera port etc. which makes it most suitable microcontroller for IoT based embedded applications. It is also used to make many kind of servers like Print server, Media Server, Web Server etc. Today we will learn how a Raspberry Pi can convert a normal speaker having 3.5mm jack into a…
As devices continue to shrink and customers demand ever sleeker products, Maxim Integrated introduces the MAX98390 smart amplifier with integrated Dynamic Speaker Management (DSM) algorithm to efficiently deliver louder, clearer, richer sound at the lowest quiescent power in the market. The boosted, digital Class D DSM smart amplifier unleashes a system’s full audio…
When an RC phase shift oscillator employs an op-amp in its circuit, it becomes an electronic oscillator with a stable sine wave output. It functions by developing two groups of 180-degree phase shifts, one via the RC network and the other via an op-amp in an inverting circuit. Due to this phase shift arrangement, it produces nearly pure sinusoidal signals with extreme frequency stability and…

In electronics, Amplifier is the most commonly used circuit device with huge application possibilities. In Audio related electronics pre-amplifier and power amplifiers are two different types of amplifier systems which are used for sound amplification related purposes. But, other than this application-specific purpose, there are huge differences in various types of…
Audio Mixer is an essential device in Audio Electronics. The mixer mixes two or more audio signals into a one (Mono) or two output (Stereo). The audio mixer uses audio mixing process where multiple sounds are combined to form a single or multi-sound. It is a widely used process in Live concerts, televisions, films, music industries etc.
In this…
