The world’s largest speaker, the sound can transmit 12 kilometers!

Where is the largest horn in the world? How big is it? Now it is coming.

Friends who are familiar with Chinese history must remember the history of the confrontation between the two sides of the Taiwan Strait on Kinmen Island, right? In the past, Kinmen Island was the first line of defense between the Kuomintang and the Communist Party. It was once the most militarized area in the world, with more than 100,000 soldiers stationed there. Across the shallow strait is the famous Dadeng Island.

Times have changed, and peace and development have become the themes of today’s era. The former war zone has become a battlefield sightseeing park to receive tourists from Taiwan and the mainland. It is understood that the sightseeing park has used the special geographical location and war relic resources to protect and transform the former military frontline broadcasting station and other battlefield facilities, forming a unique military education base.

Built in the 1960s and 1970s, this military radio horn is cast from lead and aluminum, with a maximum diameter of 2.88 meters(9.44ft), a length of nearly 5 meters(16.41ft), and a weight of 1,588 kilograms. Based on the principle of bionics, this speaker is powered by compressed air and controlled by voice and electrical signals to generate and transmit strong sound waves with a maximum power of 20,000 sound watts and an effective sound transmission distance of 12 kilometers. The sound waves generated can clearly cross the sea and reach Kinmen Island. It was the main tool used by the mainland to broadcast and publicize Kinmen Island, which is 6 kilometers away. This super loudspeaker played its role in that area.

It is said that when a loudspeaker is broadcasting, if a person approaches the mouth of the speaker, the eardrum will be damaged by the powerful sound waves. The effective sound transmission distance of this broadcasting tool at that time could reach 12 kilometers. Dadeng Island is only 3 kilometers away from Kinmen! At that time, when the trumpet sounded, it could resound throughout Kinmen Island.
