Have you noticed some handheld microphones have a bump on it? You may have been wondering what this bump is for.
The answer is to prevent the handheld microphone from slipping from a hand, or rolling off a desk or podium. When we visit schools or houses of worship, we find a lot of microphone heads stay dented. When someone drops a microphone to the floor, it damages not only the microphone itself but also the audience's ears if the microphone is on. This small bump helps to avoid such situations.
