Sound of Love exhibition car audio system丨Sound of Love confirms application for 2024 Golden Album Award

Application Technology丨Love Sound Exhibition Car Sound System

Application field: Intelligent cockpit

Unique advantages:

The audio system of this exhibition car is a full-stack audio system solution created by Sound of Love based on the development trend of car audio and the technical research of "digital amplifier + high-performance speaker + sound algorithm + tuning". It has multiple sound effect modes (stereo/virtual surround sound/panoramic sound, etc.) to choose from, active noise reduction, simulated sound waves in the car, dynamic speed compensation and other functions, aiming to bring users a purer, quieter, more personalized and more immersive listening experience.

1. High-performance DSP amplifier: It adopts the self-developed 20CH luxury platform amplifier, which can support up to 27 speakers, supports adaptive power tracking technology, and the boost power supply voltage can be adjusted according to the output power, reducing losses and improving audio characteristics, focusing on creating differentiated functions such as headrest speakers, 4D seat rhythm, and panoramic sound. 2. High-performance speakers: It adopts self-developed luxury platform speaker products, including 25mm silk film tweeters, 100mm dual magnetic circuit design paper cone midrange, 165mm high-efficiency PP cone bass, 200mm subwoofer, 65mm composite paper cone surround, 55mm mica cone ceiling speaker, and a new 50mm seat vibrator. This series of bass has a sensitivity of 87dB, and the mid-high frequency speaker has a sensitivity of 90dB, and has low distortion and low compression characteristics. The full range of luxury platform speakers uses neodymium iron boron rare earth magnets, which brings higher transducer efficiency and lower quality. Combined with the ultra-high sensitivity design of the speaker, it highlights the efficient and green design concept of this platform. In addition, the rear surround and ceiling speakers maintain small size layout flexibility. This platform speaker is designed to bring users surging bass, sweet mids and clear highs, bringing users a high-efficiency, dynamic green audio experience. 3. Sound effect algorithm: Guided by customer needs, we independently developed various sound effects, active NVH, simulated sound wave and other algorithms, and provide customers with cost-effective full-stack solutions based on common DSP and SoC platforms. 4. Professional tuning: Using precision microphones and sound cards to build a tuning measurement matrix, through multi-position online real-time monitoring, global optimization tuning is performed on all positions of the vehicle, combined with self-developed algorithms, to bring users a variety of real and virtual sound effects experience.

Application scenarios:

Stereo mode: Based on the arrangement of multiple speakers throughout the car, the stereo sound field is restored to provide HiFi enthusiasts with an authentic music feast. 2D virtual surround mode: The 2D virtual surround algorithm efficiently adjusts the width and depth of the sound field, optimizes the sound field positioning and spatial atmosphere, and provides users with cost-effective virtual surround effects. 3D virtual surround mode: Based on the arrangement of corresponding speakers on the roof, the 3D virtual surround algorithm comprehensively expands the width, depth and height of the sound field, further expands the sound field space, creates a stereo three-dimensional listening experience, and strengthens the on-site atmosphere. 4D dynamic mode: 3D + seat vibration, by analyzing the rhythm information of the music, optimizes the seat vibration experience, allowing hearing and touch to deeply perceive bass and shock waves together. 7.1.4 panoramic sound mode: 100% restores panoramic sound to provide customers with the ultimate surround effect. Simulated sound waves: High-fidelity sound wave synthesis uses the latest particle synthesis technology to create rich building blocks, and designs high-quality sound wave signal streams that combine traditional engine sounds with modern science fiction sounds on demand, providing customers with realistic or magical engine roars.

Future prospects:

With the continuous development of intelligent automobile technology, automobiles will gradually become the third mobile space. Improving the intelligence of the automobile listening environment, immersive experience and cabin quietness has become a new topic. We will also further develop new functions based on this exhibition car to achieve intelligent listening scenarios from 3D listening to 4D/5D listening effects and cross-domain integration to meet the new trend of future automobile audio development.

Golden Album Award Introduction:
