Loudspeaker Enclosure System With Signal Processor For Enhanced Perception Of Low Frequency Output
ActiveUS20140341394A1Minimize overload distortionEnhanced low frequency outputSignal processingGain controlResonant cavityHarmonic
A loudspeaker system with a transducer and an enclosure with at least one resonant chamber, including a resonant-chamber resonance frequency, at which a displacement characteristic of a vibratile diaphragm of the transducer has a minimum. The loudspeaker system further includes a multi-mode signal processor with a set of signal processes wherein in one example, a variable gain, frequency selective dynamic filter reduces the gain in a high displacement frequency range upon an output in the frequency range exceeding an overload amplitude threshold. The gain reduction is compensated for by complimentary frequency generating signal processes, including at least one of a harmonics generator and a transpositional gain controller, with the signal processor adapted to match the resonant chamber enclosure by substantially maintaining or increasing acoustic output at the resonant chamber resonance and generating harmonics associated with fundamental frequencies in the gain reduced frequency range to maintain a perception of tonal quality and physical bass impact, increasing low frequency capability while minimizing audible overload distortion.

Firstly, deep ploughing and land preparation are carried out, 1600-2400kg / mu of decomposed fertilizer is applied; then, ridging is carried out according to the line spacing of 100-120cm with the ridge height of 20-30cm and the ridge bottom width of 75-95cm; the double-line application of 16-24kg / mu of compound fertilizer, 35-45kg / mu of phosphate fertilizer, 12-20kg / mu of potassium sulphate, 1-2kg / mu of zinc sulfate and 15-25kg / mu of cake fertilizer is carried out during ridging; the tobacco seedling transplantation period is from later January to the medium May, punching is carried out according to the row spacing of 45-55cm with the hole width of 10-15cm and the depth of 15-20cm; before transplantation, 4-6kg / mu of compound fertilizer and 3-5kg / mu of potassium sulphate are subjected to hole application; after transplantation, 2-3kg of Dinggen water is poured, a mulching film is covered, and the distance between the top of the tobacco seedling to the mulching film is 10-15cm; when the top of the tobacco seedling supports the film after transplantation is carried out for 15-25 days, the seedling is led to cover soil and seal a dibble; and when the tobacco seedling enters the bloom growing period after transplantation is carried out for 30-40 days, earthing, weeding and watering are carried out. According to the method, the growth and the development of the tobacco seedling can be accelerated, the biomass accumulation is increased, the tobacco yield and quality can be improved, the faint scent flavor of the tobacco is reinforced, and the tobacco seedling illness catching rate is lowered.
