摘要： A protective screen for a diaphragm of a loudspeaker comprises a first side and a second side. The screen comprises a perforated region and an imperforated region. The perforated region comprises a first perforation having a first size and a second perforation having a second size, each perforation passing through the first side and the second side of the screen, and each perforation allowing sound waves radiated from a first portion of the diaphragm to pass through the screen. The imperforated region suppresses sound waves radiated from a second portion of the diaphragm. The first perforation is more adjacent to the imperforated region than the second perforation, and wherein the second size of the second perforation is bigger than the first size of the first perforation.

摘要： An acoustic filter includes holes and is configured to receive sound waves generated by an audio driver of a playback device. The sound waves comprise sound waves of a first frequency that radiate according to a first radiation pattern and sound waves of a second frequency that radiate according to a second radiation pattern that is less directed along an axis of the audio driver than the first radiation pattern. The second frequency is lower than the first frequency. The acoustic filter is configured to attenuate the sound waves of the first frequency so that the attenuated sound waves of the first frequency are emitted from the acoustic filter according to an effective radiation pattern that is less directed along the axis of the audio driver than the first radiation pattern and pass the sound waves of the second frequency in substantial accordance with the second radiation pattern.

摘要： This invention discloses a kind of speaker structure with a loading hole. A characteristic is that it includes an active cavity that has a cone hole and a loading hole; a loudspeaker is sealed and secured on the said cone hole; the said active cavity is connected to the outside air through the said loading hole; the cone of the said loudspeaker has one side which is connected to the free space; another characteristic of this invention is that it includes a driven cavity that is connected to the said active cavity through the said loading hole; the cross-sectional area of the said loading hole is smaller than the cross-sectional area of the air passage on its either side; further, it is not larger than ⅔ the effective area of all the vibration units in the said active cavity; also, the volume of the said active cavity does not exceed half the total volume of the said active cavity and driven cavity. The loading hole constitutes a loading component which improves the transient response of the speaker body. To a great extent, it solves the contradiction between frequency response and transient effect at low sound frequencies. It lowers the requirements for the loudspeaker and simultaneously allows the frequency response and transient effect for the entire system at low sound frequencies to be handled relatively independently. This causes the loudspeaker cost to be reduced.
