AI Technical Summary
The effective sound-producing area of conventional loudspeakers is limited by the product's size, and the diaphragm vibrates without pistons, making it difficult to increase the effective sound-producing area of the vibration system and adapt to the demand for thinner and lighter smart products.
It adopts a dual voice coil driven dual diaphragm structure. The space between the diaphragms is divided into a front cavity and a rear cavity by a partition plate, and the cavity is isolated by a slit to increase the effective vibration area. At the same time, the viscosity of air flow is used to form high impedance to isolate the cavity. The shell is set with multiple sound holes to enhance the sound wave output.
Without increasing product size, the effective vibration area and sound loudness of the vibration system are increased, the internal space is fully utilized, and the driving force and acoustic performance of the voice coil are enhanced.
