AI Technical Summary
Existing passive speakers face challenges in low-frequency processing and tuning, making it difficult to achieve higher levels of low-frequency effects through speaker units and cabinet volume. Furthermore, due to cost and the limitations of pure power amplifiers, improving low-frequency sound effects is difficult.
Adding sound-absorbing cotton to the speaker enclosure, especially by fixing it with rivets on the back panel, using sound-absorbing cotton filled with polyester fiber material, and placing sound-absorbing cotton between the woofer and the bass reflex port to improve low-frequency sound effects.
By adding sound-absorbing cotton, the speaker system's sensitivity below 100Hz is improved, and the low-frequency sound becomes fuller.

TECHNICAL FIELD
[0001] The utility model relates to sound technology field especially a sound box low frequency supplementary enhancement device. BACKGROUND
[0002] The existing passive sound box does not have active power amplifier to process and debug bass, and only relies on the volume of loudspeaker unit and box to process and debug low frequency, which is difficult to make the low frequency of the system to another level. SUMMARY
[0003] The utility model solves the technical problem to provide a kind of sound box low frequency supplementary enhancement device, simple structure, low frequency audio effect is enhanced.
[0004] To solve the above technical problems, the technical scheme of the utility model is: a kind of sound box low frequency supplementary enhancement device, the sound box includes box and bass loudspeaker, the box includes panel and backboard, the bass loudspeaker is installed on panel, and the box is in the rear of bass loudspeaker and is equipped with sound-absorbing cotton.The principle of the utility model is: after increasing sound-absorbing cotton, the sensitivity of sound box system curve below 100HZ is improved, and in the sense of hearing, low frequency is more full than the sense of hearing when not adding more sound-absorbing cotton.
[0005] As an improvement, the sound-absorbing cotton is arranged on the backboard.
[0006] As an improvement, the sound-absorbing cotton is fixed on the backboard by rivets.
[0007] As an improvement, the sound-absorbing cotton is filled with polyester fiber material.
[0008] As an improvement, the box is equipped with an inverter pipe on the backboard, and the sound-absorbing cotton is arranged below the bass loudspeaker and the inverter pipe.
[0009] The utility model compared with prior art brings beneficial effect is:
[0010] After increasing sound-absorbing cotton, the sensitivity of sound box system curve below 100HZ is improved, and in the sense of hearing, low frequency is more full than the sense of hearing when not adding more sound-absorbing cotton. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 It is internal schematic diagram for sound box. DETAILED DESCRIPTION
[0012] The utility model is further described below in conjunction with the drawings of specification.
[0013] As Figure 1The utility model discloses a kind of sound box low frequency supplementary enhancement devices, the sound box includes box 1, bass speaker 3, tweeter 2 and inverter tube 4.The box 1 includes panel, back plate, bottom plate, top plate and side plate.The bass speaker 3 and tweeter 2 are arranged in box 1, the bass speaker 3 and tweeter 2 are installed on panel, the tweeter 2 is located above bass speaker 3 and is separated by baffle between the two.The box 1 is in the rear of bass speaker 3 and is provided with sound-absorbing cotton 5, and the sound-absorbing cotton 5 is fixed on back plate by rivet.The inverter tube 4 is arranged on back plate in box 1, and sound-absorbing cotton 5 is arranged between bass speaker 3 and inverter tube 4, and the sound-absorbing cotton 5 is fixed on bottom plate.The sound-absorbing cotton is filled with polyester fiber material, and the thickness of sound-absorbing cotton can be changed according to different types of sound-absorbing cotton.
[0014] The utility model principle: after increasing sound-absorbing cotton 5, the sensitivity of sound box system curve below 100HZ will be improved, and in the sense of hearing, low frequency will be more full than that without adding more sound-absorbing cotton 5.
