Outdoor speakers

Client country: China

Services: industrial design｜machine design｜functional prototyping

Project Background

Against the backdrop of the booming outdoor events like large-scale parties and music festivals, there has been a surging demand for high-power, highly adaptable outdoor audio devices. Existing portable speakers generally suffer from insufficient sound pressure and limited sound field coverage, failing to meet the amplification needs of large gatherings. Developed to address this pain point, this outdoor speaker fills the gap in audio equipment for large-scale outdoor entertainment scenarios with its powerful sound and stable performance.

Solution

Core Objectives

Address the four core pain points of insufficient sound pressure, uneven sound field coverage, short battery life, and poor environmental adaptability in large-scale outdoor parties and entertainment events, and create a professional-grade mobile audio device tailored for multi-person gathering scenarios.

Specific Solutions

1.High-Power Acoustic SolutionEquipped with dual 10-inch subwoofers and high-frequency horn units, it delivers a peak power of 300W, supports stereo/mono dual-mode switching, and achieves a sound field coverage radius of up to 50 meters, meeting the amplification needs of large parties with 50–200 people. Built-in DSP sound chip comes with preset scene modes including party, rock and folk, automatically optimizing sound quality to avoid distortion.

2.Long-Lasting Battery & Fast Charging SolutionFitted with a large-capacity 12000mAh lithium battery, it supports continuous playback for ≥12 hours. It features 20W fast-charging technology—2 hours of charging provides 8 hours of usage. An additional solar panel enables emergency charging, making it suitable for outdoor scenarios without power supply.

3.Portability & Stability SolutionAdopts a lightweight alloy frame paired with wear-resistant rubber wheels, with the cabinet weight controlled within 15kg for easy single-person towing and movement. The bottom is equipped with retractable fixed brackets and wind rope interfaces, capable of withstanding level 5 outdoor winds and preventing equipment tipping.

4.Smart Connectivity & Triple Protection SolutionSupports Bluetooth 5.3, NFC quick pairing and wired microphone connection, compatible with multi-device series connection for stereo expansion. The body adopts IPX5 waterproof and dustproof design, which can cope with complex outdoor environments such as rainy days and sandy dust.

Design Process Outline For Outdoor Large-Scale Party Speak

Core Orientation: Focus on “high power, strong adaptability, stable performance, and easy portability” to meet the needs of large-scale outdoor partyscenarios

I. Preparatory Stage (1-2 Weeks)
