What is the benefit of using permanent magnets in head telephones?

• A. Place the diaphragms under tension to increase sensitivity
• B. Improve the frequency response
• C. Prevent production of second harmonics in the telephones
• D. All of the above

Answer: (D)

Using permanent magnets in head telephones provides several key benefits that contribute to the overall performance and quality of sound reproduction. One of the primary advantages is the way these magnets enhance the design of the headphones, allowing diaphragms to be positioned effectively for improved sensitivity. When diaphragms are under the right amount of tension, they can vibrate more efficiently in response to electrical signals, leading to better sound quality with increased perceived volume. Additionally, the presence of permanent magnets contributes to the frequency response of the headphones. A well-designed magnet system allows the driver to reproduce a wider range of frequencies accurately, which is crucial for achieving a balanced sound that many listeners desire. Furthermore, the use of permanent magnets helps in minimizing distortion, particularly unwanted harmonics, such as second harmonics. This aspect is vital for maintaining sound clarity, especially when playing complex audio signals. Thus, the benefits of using permanent magnets in head telephones encompass improvements in sensitivity, frequency response, and reduced distortion, making the option that encompasses all these factors the most comprehensive and accurate choice.
