What is the diameter of a 6.5-inch speaker in centimeters?
1 Answers
6.5-inch speakers generally have a diameter of approximately 16.5 centimeters. Working principle of speakers: The working principle of an air horn is to use the airflow of compressed air to vibrate a metal diaphragm and produce sound. Therefore, it can only be used on vehicles equipped with an air compressor. Air horns are generally installed on large buses and heavy-duty trucks, especially for long-distance transport vehicles driving in mountainous areas or curves. Using an air horn can effectively alert pedestrians and oncoming drivers. This is because air horns have high volume, good sustain, pleasant sound, and can be heard over long distances. Air horns are typically cylindrical and use a combination of high-pitch and low-pitch horns. The working principle of an electric horn is to use electromagnetic force to vibrate a metal diaphragm and produce sound. It is a widely used type of horn in automobiles, classified into three structural forms: cylindrical, spiral, and cone-shaped, with spiral and cone-shaped being the most common. Classification of horns: Automobile horns are divided into air horns and electric horns based on their sound power; into cylindrical, spiral, and cone-shaped based on their appearance; and into high-pitch and low-pitch horns based on their frequency.
