Patented DAD Design
The DAD (Dedicated Airflow Distribution) design is a specific feature that aims to optimize the airflow within the earphone housing.
The DAD design provides a dedicated path (TUBE) for airflow between the front and rear acoustic chambers of the earphone, improving dynamic driver performance and sound quality.
Dynamic driver earphones are equipped with two separate bores which serve specific purposes:
Front chamber bore: The bore to the front acoustic chamber of the earphone is designed to balance the internal and external pressure. This helps to maintain the stability and performance of the earphone. By equalizing the pressure, the front chamber bore ensures that the sound produced is accurate and free from distortion caused by pressure imbalances.
Rear chamber bore: The bore in the rear acoustic chamber of the earphone is crucial for the free movement of the driver diaphragm, which is responsible for sound generation and must move freely to ensure faithful sound reproduction. The bore in the rear chamber provides the necessary airflow so that the driver diaphragm can move more easily and accurately, resulting in a better sound experience.
The DAD (Dedicated Airflow Distribution) design is a special feature that aims to optimize the airflow inside the earphone housing. Find a more detailed explanation of the DAD design below:
Enhanced airflow: The DAD design incorporates a tube that connects the front and rear acoustic chambers. This tube serves as a dedicated pathway for airflow, allowing for more efficient and controlled distribution of air within the earphone housing
Improved driver diaphragm movement: The increased airflow created by the DAD design facilitates the movement of the driver diaphragm, which is responsible for sound production. As a larger volume of air flows through the rear chamber bore, the driver diaphragm can move more freely and precisely, resulting in improved sound reproduction and fidelity.
Reduced distortion: By optimizing the airflow through the DAD design in the earphone, distortion caused by pressure imbalance is minimized. The balanced airflow helps maintain a stable internal and external pressure that ensures the sound produced is accurate and free from unwanted artifacts.
Enhanced sound quality: The DAD design's focus on optimizing airflow contributes to an overall improvement in sound quality. The increased airflow allows for better control and precision in sound reproduction, resulting in a more intense and enjoyable sound experience.
Design considerations: The DAD design is based on the principles of aerodynamics and airflow. Engineers carefully consider factors such as the diameter and length of the tube (accurate to 0.01 mm) and the placement of the front and rear acoustic chamber bores to achieve optimal airflow distribution and performance.
