Abstract
The utility model relates to a super-low voice sound box. A treble loudspeaker and a middle-frequency loudspeaker are arranged on the front panel of the sound box, and a low voice loudspeaker is arranged at a middle position in the body of the sound box. When the sound box works, normal and reversed phase waves generated by the low voice loudspeaker are superposed to circle in the sound box via a reversed phase sound hole in the sound box, the range of voice is broadened, super-low voice frequency is generated, and the superposed normal and reversed phase waves release super-low voice out of the sound box through the reversed phase sound hole in the front panel of the sound box.
Description
The utility model subwoofer audio amplifier relates to change the audio amplifier that is widely used in broadcast stereo equipment loudspeaker box structure.
At present, existing audio amplifier is a casing with wooden or plastic material, be by height on the front panel of audio amplifier, in low or high, the woofer size punches on the plate in front and is fixed on different each audio tweeter on the front panel and opens the paraphase sound hole on the suitable position on the plate in front, the audio amplifier of said structure, when being used, people can't obtain lower subwoofer frequency, because it is installed in woofer on the front panel, make woofer cone back side when work change the backward-wave of penetrating, the reflection of plate after in casing, discharge to the front by the paraphase sound hole, the backward-wave phase place is discharged towards a direction by 180 ° of forward waves with the cone front of paraphase, with the sound that helps that obtains the audio amplifier paraphase when the speaker operation, but the subwoofer to audio amplifier helps the sound wave effect not abundant, and its backward-wave has only 180 °
The utility model, overcome above-mentioned shortcoming, be on the fixed mount in being fixed in the casing by audio amplifier woofer, fixedly change on the optional position change when audio amplifier provides a kind of woofer to work in case with loud speaker installation and design structure penetrate instead, forward wave overlaps around the subwoofer audio amplifier that discharges forward through the paraphase sound hole.
The utility model subwoofer audio amplifier, its feature: by wooden or plastic material is the sound box bodies of making of matter, on the audio amplifier front panel, open if a hole, size according to different holes is fixed on one or more groups height, middle pitch or high pitch loudspeaker on the front panel, hole remaining on the front panel is as the paraphase sound hole, and on the optional position in being fixed in the casing by fixed mount, one or several paraphase sound holes are also arranged on the fixed mount to woofer.The low frequency characteristic of subwoofer audio amplifier is mainly determined by woofer, when work, produce and frequently shake, during woofer is installed in the audio amplifier, air violent oscillatory motion in the audio amplifier with bass, the diffuser back side and front just produce anti-, forward two ripples, the backward-wave of penetrating is changeed at the diffuser back side, through 180 ° of the reflections of cabinet wall, discharge forward by the paraphase sound hole on the case inner fixed stand, the backward-wave phase place by paraphase overlap with the forward wave of cone front in sound box bodies, carry out around, range is broadened, produce the subwoofer frequency response and woofer is played the effect that helps applicator good, anyway to coincidence ripple discharges the rich powerful subwoofer of generation at the paraphase sound hole on the audio amplifier front panel and brings up of tremendous momentum acoustics in case outside casing.
Below in conjunction with accompanying drawing the utility model is described.
Fig. 1 is the outside drawing of audio amplifier, and 1,2 is high, Squawker among Fig. 1, and 3 is the paraphase sound hole of audio amplifier, and 4 is sound box.Fig. 2 is the simple sectional side view of audio amplifier, in Fig. 2,1,2,3,4 with Fig. 1 in 1,2,3,4 identical, 5 is woofer.
Claims (1)
1, subwoofer audio amplifier, be combined into high, medium and low loud speaker, sound box bodies, paraphase sound hole, its feature: by wooden or plastic material is that matter is made sound box bodies, on the audio amplifier front panel, open if a hole, according to the size in different holes one or more groups height, middle pitch or high pitch being raised one's voice is fixed on the front panel, and the hole on the front panel on surplus is as the paraphase sound hole, and woofer is passed through fixed mount, on the optional position in being fixed in the casing, one or several paraphase sound holes are arranged also on the fixed mount.
