    摘要： The present invention provides a speaker module comprising a peripheral frame and speaker units housed in the peripheral frame, and the peripheral frame is provided with sound holes in communication with the outside, a front acoustic cavity in communication with the sound holes is defined between one side of the speaker units and the peripheral frame, and a rear acoustic cavity is defined between the peripheral frame and another side of the speaker units away from the front acoustic cavity; in which the speaker units are provided in plurality, and the rear acoustic cavity is divided into the same number of rear sub-cavities as that of the speaker units, and each of the speaker units corresponds to one of the rear sub-cavities and is in communication with its corresponding rear sub-cavity. The above structure makes it easier to adjust the acoustic performance and improves the stereo effect of the product.

    摘要： A loudspeaker is provided that passively achieves a directional polar response at low frequencies with a high degree of attenuation between the front and the back of the loudspeaker. The loudspeaker 11 has a transducer 13, an enclosure 21 behind the transducer, and port openings 29 in the sidewalls 23 of the enclosure to allow a back-wave produced by the transducer to exit the enclosure and combine with the front wave produced by the transducer. Cancellation behind the loudspeaker at low frequencies is achieved by delaying the back wave with low loss. Low loss delay at low frequencies is achieved by inserting a low-density fibrous fill material 33 in the acoustic chamber 27 formed behind the transducer 13 by the enclosure 21. A fibrous material is selected having a low-pass transfer function and low acoustic loss in its low-frequency pass band.
