Product Introduction - Automotive Active Sound Control System

1. System Overview

The Automotive Active Sound Control System utilizes advanced acoustic technologies to provide customized sound experiences for vehicles. Comprising two core functional modules - Active Sound Enhancement (ASE) and Active Sound Synthesis (ASS) - the system is suitable for both traditional fuel vehicles and electric vehicles, enhancing driving pleasure and brand recognition.

2. Core Technologies

(1) Active Sound Enhancement (ASE)

Technical Principle:

Analyzes engine order sounds to identify key frequency bands

Uses Digital Signal Processing (DSP) technology to dynamically compensate and enhance target order sounds, making engine acoustics fuller and more sporty

Application Effects:

Enhances low-RPM torque sound in fuel vehicles, improving acceleration feedback

Optimizes in-cabin acoustic environment by reducing unwanted noise and elevating luxury feel

(2) Active Sound Synthesis (ASS)

Technical Principle:

Collects real-time vehicle data including RPM, speed, and throttle position

Synthesizes matching engine sounds through algorithms and plays them via interior/exterior speakers to simulate combustion engine acoustics

Application Scenarios:

Ideal for electric vehicles to provide combustion-engine-like acceleration sounds, enhancing driving immersion

Supports customization of various sound styles (e.g., V8/V10 engine sounds, futuristic sound effects)

3. Core Hardware Components

(1) Sound Generator
