Abstract

A public address system for teaching based on a cellphone Bluetooth function. The system comprises a smart cellphone (1) with a Bluetooth function, a microphone (5) matching with the smart cellphone, a multimedia teaching computer (2), and a Bluetooth receiver (3). The microphone (5) passes voice information to the smart cellphone (1), the smart cellphone (1) passes the voice information to the Bluetooth receiver (3) via Bluetooth, and the multimedia teaching computer (2) receives the voice information from the smart cellphone (1) via the Bluetooth receiver (3) and plays the voice information via a speaker box (4). The public address system for teaching uses a smart cellphone as a Bluetooth transmitting point to send voice information to a multimedia teaching computer via Bluetooth. Therefore, as long as a teacher carries the smart cellphone, the teacher can play high-quality voice information via the multimedia teaching computer even if the teacher walks around a classroom, thereby making the teaching by the teacher more convenient.
