Claims
- 1. A bass reproduction speaker apparatus, comprising:
a cabinet with two openings; a speaker unit disposed at the first opening of the cabinet, having a diaphragm for emitting sound waves; an amplifying means for driving the speaker unit; a bass enhancing member that enhances bass range sound waves, said bass enhancing member is disposed at the second opening of the cabinet; a vibration detecting means, included in the bass enhancing member, for detecting vibration of the bass enhancing member and for releasing detecting signals; and a feedback means for negatively feeding back the detecting signals to the amplifying means.
- 2. The bass reproduction speaker apparatus according to claim 2, further comprising a second vibration detecting means, included in the said speaker unit, for detecting vibration of the speaker unit and for releasing second detecting signals; and a second feedback means for negatively feeding back the second detecting signals to the amplifying means.
- 3. The bass reproduction speaker apparatus according to claim 3, further comprising a current measurement means electrically coupled with the speaker unit and having an output, said output is indicative of the current through the speaker unit; and a third feedback means to negatively feeding back the output from the current measurement means to the amplifying means.
- 4. A bass reproduction speaker apparatus, comprising:
a cabinet having an opening and a division member inside thereof, the division member forming a closed space inside the cabinet; a speaker unit having a diaphragm, said speaker unit disposed at the division member of the cabinet; an amplifying means for driving the speaker unit; a bass enhancing member that enhances bass range sound waves, said bass enhancing member is disposed at the opening of the cabinet; a vibration detection means, included in the bass enhancing member, for detecting vibration of the bass enhancing member and for releasing detecting signals; a feedback means for negatively feeding back the detecting signals to the amplifying means; an equalization means receives system input and has an output coupled to the input of said amplifer means, said equalization means exhibiting a high-pass characteristic; and when the system input bypasses the equalization means and couple to the said amplifier input, said speaker apparatus exhibits a negative slope characteristic between the two resonance frequencies in the low frequency range.
- 5. The bass reproduction speaker apparatus according to claim 4, further comprising a second vibration detecting means, included in the said speaker unit, for detecting vibration of the speaker unit and for releasing second detecting signals; and a second feedback means for negatively feeding back the second detecting signals to the amplifying means.
- 6. The bass reproduction speaker apparatus according to claim 5, further comprising a current measurement means electrically coupled with the speaker unit and having an output, said output is indicative of the current through the speaker unit; and a third feedback means to negatively feeding back the output from the current measurement means to the amplifying means.
- 7. A bass reproduction speaker apparatus, comprising:
a cabinet having a division member inside thereof, the dividing member forming two closed spaces, the cabinet having one opening in each of the said closed space; a speaker unit having a diaphragm, a first voice coil mechanically coupled with the diaphragm, said speaker unit disposed in the dividing member of the cabinet; an amplifying means for driving the speaker unit; a first bass enhancing member that enhances bass range sound waves, said bass enhancing member is disposed at the first opening of the cabinet; a second bass enhancing member that enhances bass range sound waves, said bass enhancing member is disposed at the second opening of the cabinet; a first vibration detection means, included in the first bass enhancing member, for detecting vibration of the first bass enhancing member and for releasing first detecting signals; a second vibration detection means, included in the second bass enhancing member, for detecting vibration of the second bass enhancing member and for releasing second detecting signals; a first feedback means for negatively feeding back the first detecting signals to the amplifying means; and a second feedback means for negatively feeding back the second detecting signals to the amplifying means.
- 8. The bass reproduction speaker apparatus according to claim 7, further comprising a third vibration detecting means, included in the said speaker unit, for detecting vibration of the speaker unit and for releasing third detecting signals; and a third feedback means for negatively feeding back the third detecting signals to the amplifying means.
- 9. The bass reproduction speaker apparatus according to claim 8, further comprising a current measurement means electrically coupled with the speaker unit and having an output, said output is indicative of the current through the speaker unit; and a forth feedback means to negatively feeding back the output from the current measurement means to the amplifying means.
