Classroom Sound System

SPON Classroom Sound System

Current Situation Analysis


As the demands for classroom sound systems keep increasing, the drawbacks of traditional classroom audio systems are becoming more obvious:

1. Traditional sound systems may not cover the entire classroom evenly, causing some students to not hear clearly.

2. The teacher's voice may have different volumes in different areas, affecting students' listening experience.

3. Outside noise (like hallway sounds, traffic noise) can be amplified by traditional sound systems, disrupting classroom teaching.

4. Because traditional systems cannot effectively amplify sound, teachers may need to speak loudly for long periods, leading to voice fatigue and health problems.

Needs Analysis


1. Teacher Needs

The sound equipment is easy to use, and the wireless microphone is comfortable to wear, making speaking easy.

The sound equipment needs to be used stably, and the wireless microphone should work with any speaker.

1. Student Needs

The sound equipment can cover the whole classroom, ensuring students can hear clearly.

The sound equipment should be within safe sound levels for human ears to protect hearing health.

Product Introduction


Network Equisound Speaker

SPON network equisound speaker is an intelligent product that combines audio, wireless communication, and smart control. It uses embedded system architecture and has a built-in 6-channel independent speaker system, forming a curved array balanced amplification. With sound intelligent equalization and audio intelligent analysis detection algorithms, it ensures balanced coverage at healthy sound pressure levels, addressing issues of unfair distribution of teaching resources and healthy sound environments in schools.

Product Application


Full Coverage Multimedia Teaching

It supports multiple inputs and outputs, allowing connection to various audio input terminals such as mobile phones, tablets, computers, and whiteboards.

Uniform Sound Filed

Just one speaker installation is enough for classroom use, with the entire space having a sound field non-uniformity of ≤2dB. Teachers can speak easily, and students can hear clearly.

Comfortable Ear Protection

Using a mobile app, adjust the speaker configuration based on the actual classroom size, ensuring that the volume in every corner of the classroom stays within a safe and healthy sound pressure range, reducing the risk of hearing health damage.

One teacher, one mic

The equisound speaker supports multiple wireless microphones for simultaneous use. Teachers can bring their own microphone and use it wirelessly in any classroom, promoting the "one teacher, one mic" approach.

Multimedia Amplification

The equisound speaker supports both Bluetooth and wired audio source inputs, meeting the multimedia amplification needs of whiteboards. Bluetooth audio source input eliminates the need for wiring construction and is compatible with various devices such as whiteboards, phones, and computers, making it more convenient to use.

High-fidelity Vocal Reproduction

Using a 24kHz sampling rate ensures the quality of voice. The audio undergoes audio algorithm processing before and after transmission, ensuring high-fidelity audio effects.

Mobile  APP Management

The equisound speaker supports phone app management. The device can communicate with phones via Bluetooth at close range. When used for the first time, users can set up, configure the speaker, and perform network settings through the smartphone app. This reduces the learning curve for users and makes construction operations more convenient.
