WT32i is an audio-specific Bluetooth 3.0 module with excellent RF performance and enhanced audio capabilities for a first-class Bluetooth audio experience. In addition to the certified Bluetooth radio and software stack, the WT32i includes a DSP, stereo audio codec and battery charger, making it ideal for fixed and portable audio applications. The WT32i includes Bluegiga's iWRAP6 Bluetooth stack software that implements A2DP, AVRCP v.1.5 profiles and supports aptX® and AAC audio codecs for stereo audio applications. For hands-free applications, iWRAP6 software also supports HFP v.1.6, HSP, MAP and PBAP as well as CVC® echo cancellation software. For data communication with Android and iOS applications, iWRAP6 also implements Bluetooth Serial Port Profile (SPP) and Apple iAP profile. The WT32i is an ideal solution for developers who want to quickly integrate the latest Bluetooth audio technology without the time and cost typically involved in Bluetooth audio chipset design.
In recent years, the development of wireless technology has gradually matured into an indispensable trend in daily life, such as WIFI, Bluetooth and 2.4GRF transmission, etc., which have brought many conveniences in life, and wireless speakers are one of them. In addition, the increasing development of wireless transmission technology has also led to the wirelessization of music peripheral products. This is a technological breakthrough, which also allows this type of product to have more imagination in the design, and also makes the fun of enjoying music more seamless. burden.
A microphone is a transducer that converts sound into electronic signals. It can transmit human speech to electronic devices to distant places or amplify the sound signal through speakers. In recent years, the development of wireless technology has gradually matured and become an indispensable trend in daily life, such as WIFI, Bluetooth and 2.4GRF transmission, etc., which have brought many conveniences in life, and wireless microphones are also one of them, allowing microphone users such as teachers to attend class. It is more convenient to go out with a tour guide to introduce attractions, speakers and karaoke singing.
In recent years, with the rapid development of wireless network technology and the improvement of bandwidth, wireless network audio and video streaming application products have become more and more popular, such as wireless network cameras, wireless baby monitors, Internet radios, and wireless speakers.
The smart phone dock speaker system can be connected to commonly used smart phones on the market such as Apple Iphone or Android phone, and can play audio and video files through docking connection. It is widely used in personal entertainment or home audio and video playback. The smart phone base speaker system must include a high-performance microcontroller to control USB signal conversion and transmission, LCD display transmission, power management, mobile phone charging, wireless remote control device reception, sound quality optimization chip control, etc. Since the working requirements of smart phone base speaker systems require high-performance microcontrollers with USB interfaces, Nuvoton's NUC123 series is very suitable for this application.
Today's smartphones/mobile tablets/tablet computers are all designed to play music and audio with high quality and low power consumption.
Today's smartphone/phablet/tablet designs require high-quality music and audio playback with low power consumption.
