How to Design the Dimensions of the Port Tube of a Bluetooth Speaker?
First, Caliber: The inner diameter is generally 1/3 to 1/2 of the speaker driver diameter. If the caliber is too small, the airflow noise will be loud; if the caliber is too large, the bass extension will be poor.
Second, Length: It must match the cabinet volume and the speaker’s Fs (free-air resonant frequency), which determines the tuning frequency fg. The length of the inner opening is included in the total effective length.
Third, Inner Opening Shape: Prioritize a circular shape with smooth chamfers to reduce airflow resistance and noise, avoiding right angles and acute angles.
