Choose from the shape of the speaker's sound outlet: round-diameter speakers have the best performance, followed by racetrack-shaped and oval-shaped speakers. Try to avoid using long and ultra-narrow speakers.
The size of the loudspeaker is selected according to the size of the box and the net volume of the box. It is necessary to select the appropriate T/S parameters and electroacoustic parameters of the loudspeaker according to the design principles of the loudspeaker.
Speaker magnet selection: external magnet (ferrite magnet) is cost-effective, but takes up a large volume, which will reduce the effective volume of the speaker box; internal magnet (rare-earth magnet) has a higher cost, but it occupies a small volume and the available volume inside the cabinet Larger, higher magnet performance.
XDEC speaker is a professional speaker manufacturer which have rich experience on design and produce speaker products,
The choice of paper cone: the shape of the paper cone often adopts linear paper cone and exponential paper cone. The linear paper cone has simple process and relatively poor high frequency performance; the exponential paper cone has better high frequency performance. In special circumstances, a double-cone design can be used. The materials of the paper cone mainly include natural fiber (plant fiber, animal fiber), man-made fiber (chemical fiber, synthetic fiber) and inorganic fiber, plastic (such as PP cone), metal (such as aluminum), etc., according to the tone and cost Ask to choose.
Speaker cabinet design
The size of the cabinet needs to combine the parameters of the speaker and the net volume of the cabinet, and the two can achieve the best match to achieve the best low-frequency sound.
The material of the cabinet is generally wood and plastic, and the thickness of the material is determined according to the vibration of the cabinet and the internal resonance. When conditions permit, try to thicken the wall thickness of the box, and appropriately increase ribs on the inner wall of the box to reduce the vibration of the box and suppress the acoustic resonance inside the box.
The sealed box of the box body should be good, and there should be no air leakage, so as to avoid wind drying and impact on low-frequency performance.
The design of the inverter tube in the inverter box plays a decisive role in the low-frequency cut-off frequency of the speaker. The design position and shape of the inverter tube need to ensure the smoothness of the air flow inside the box to reduce low-frequency distortion and wind noise. The length and cross-sectional area of the inverter tube are designed and adjusted according to the volume of the cabinet and the relevant parameters of the speaker, and ensure that the speaker impedance curve is as close to the bimodal characteristic as possible,
