摘要：
A cantilever for use in supporting a stylus tip of a phonograph pickup is disclosed, which consists of a pipe of a ceramic material composed mainly of aluminum oxide. This cantilever is light weight and has a high Young's modulus. When this cantilever is attached to a phonograph pickup, reproduction loss can be remarkably reduced over all the reproduction frequency range and sounds can be reproduced having good response characteristics.
