YINGMI BK5 New Release: A Versatile Manual-Trigger Audio Explanation System

We are excited to introduce the BK5, our latest innovation in the field of visitor guidance. The standout feature of the BK5 is its intuitive manual-keypad trigger system. When a visitor approaches a specific exhibit and wishes to learn more, they simply press the corresponding number on the device to play the pre-recorded commentary. This straightforward operation requires virtually no training, making it an ideal museum audio device for visitors of all ages.

Why Manual Triggering?

While many venues look for complex setups, a manual automatic audio guide system often provides much-needed flexibility. Visitors are not forced to follow a rigid path; they can explore exhibits that pique their interest and control the narration at their own pace. This is particularly effective in complex layouts or high-traffic venues where a traditional guide system tour might be disrupted by overlapping signals. Additionally, in noisy environments, manual control allows users to replay segments easily, ensuring they never miss a detail.

Multilingual Support for International Visitors

The BK5 is a powerful museum audio tour solution that can store up to 8 different languages. For instance, in a single tour group consisting of English, French, and Japanese speakers, staff can simply switch each device to the visitor's native tongue. There is no need for multiple sets of equipment, making it a highly practical tool for international museums, scenic spots, and corporate showrooms.

Massive Capacity and Exceptional Battery Life

Designed to handle even the largest collections, the BK5 can store up to 9,999 audio tracks. Whether you are managing a massive national museum or a specialized mini art museum guide service, the storage options (512MB, 2GB, or 16GB) provide ample space for high-quality audio.

Reliability is at the core of the BK5. A single charge (approx. 6-7 hours via standard 5V charger) provides 30 to 50 hours of continuous operation. With a standby current of just 25mA, site managers can rest assured that the devices will last through multiple days of heavy use without mid-day recharging.

Crystal Clear Audio in a Compact Frame

As a dedicated museum audio device, sound quality is paramount. The BK5 features a frequency response of 100Hz–20kHz and a signal-to-noise ratio of >60dB, ensuring clear, crisp narration without distortion. All this technology is packed into a sleek, lightweight body—measuring just 100×48×18mm and weighing only 100g. It is comfortable to hold or wear around the neck for extended periods.

Versatile Application Scenarios

The BK5 excels in diverse environments, serving as a reliable:

• Natural History & Science Centers: Where large, diverse exhibits benefit from a flexible guide system tour.

• Art Galleries & Special Exhibitions: Perfect for a mini art museum guide setup where visitors decide which masterpiece to study.

• Heritage Sites: Provides a quiet, immersive museum audio tour experience without the noise of loudspeakers.

• Automotive Showrooms: Adds a layer of professional service during VIP receptions or new car launches.
