Product overview

Using the latest array wave beam directional sound technology, let the sound uniform coverage to the classroom every orientation, realize the balance of sound transmission, the system by the array wave speakers through professional simulation sound field design and audio processing technology, realize the spread of sound equilibrium, clear nature, let sound accurate coverage to the classroom environment, not only can protect students? hearing health, protect the teacher throat health, let the teacher easily, power teaching to improve the quality of classroom teaching, improve and enhance classroom teaching order, widely applicable to the large schools across the country.

major function

Directional sound expansion: directional sound will not interfere with each other, the designated area can be listened to, to avoid environmental noise

Voice without roar: voice without howling, improve students? attention, and then improve learning efficiency

Full coverage of sound: full coverage of sound, will not change significantly with the distance

Technical parameter table

With advanced DSP algorithm, it can ensure the sound field balance of the classroom and the venue. The maximum sound pressure level is 1 m 95 db in the front and 1 m 80 db in the rear.

Sound field equilibrium: using DSP phased array algorithm to adjust the beam deflection angle;

Frequency shift anti-noise: spectrum analysis of the digital signal after AD, remove the noise frequency;

Echosuppression: echo cancellation algorithm with high performance DSP;

Convenient installation: wall hanging design.

Power: 50W

Connection mode: microphone, lotus flower

application scenarios

Ordinary classroom, lecture theatre.
