how to make mini Bluetooth speaker from pvc pipe at home

Wireless speakers are loudspeakers that receive audio signals using radio frequency (RF) waves rather than over audio cables. The two most popular RF frequencies that support audio transmission to wireless loudspeakers include a variation of WiFi , while others depend on Bluetooth to transmit audio data to the receiving speaker.
Apart from the employed RF standard, such speakers can basically be distinguished by their dedicated field of use. Portable wireless speakers for outdoor use are typically designed for ruggedness, portability and battery life, whereas stationary wireless speakers with a focus on good sound quality are meant to be used in home audio systems or surround sound systems for TV or video. Further, types for special applications like waterproof speakers for use in the shower or speakers for a voice assistant may intermix between the properties of the two former.
Most wireless speakers have a built-in microphone, which allows to receive and make calls using a mobile phone in hands-free mode. When a call comes in, the music automatically shuts off and resumes as soon as the call ends.
