Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the utility model will be described in further detail.
As shown in Fig. 1 ~ 4, a kind of sub-woofer, comprise the tubular bamboo shell 1 that inside has cylindrical cavity, open front place of described bamboo shell 1 inner chamber is provided with opening loudspeaker 2 forward, be provided with on rear side of described loudspeaker 2 and cover on loudspeaker 2 back periphery and the case 3 matched with bamboo shell inner chamber perisporium, be matched in clearance between case 3 and bamboo shell 1 inner chamber perisporium, this case 3 is plastic shell, touch mutually on rear side of described case 3 opening perimembranous and described loudspeaker 2 outer edge, the inner chamber of case 3 forms inner sound chamber, and described bamboo shell 1 rear end is provided with end cap 4; Between end cap 4 and case 3 bottom surface, outside sound chamber is formed in the inner chamber of bamboo shell 1, vibration frequency and the interior sound chamber frequency in its peripheral sound chamber have difference, inner sound cavity resonant frequency mainly high pitch, outside sound cavity resonant frequency mainly bass, when loudspeaker are play, sound chamber, inside and outside portion forms audio mixing, so just produces the effect of mega bass.
It is T-shaped and along straight trough 5 from bamboo shell 1 lumen shaft to setting that bamboo shell 1 inner chamber perisporium is provided with cross section, bamboo shell 1 rear end is run through in this straight trough 5 rear end, push rod 6 is provided with in described straight trough 5, push rod 6 is provided through the cannelure of straight trough 5 and stretches into the hook-type compressed part 7 of bamboo shell 1 inner chamber near case one end, this hook-type compressed part 7 is pressed in case 3 rear end face, the spring 8 be sandwiched between end cap 4 and push rod is provided with in straight trough 5, under spring 8 thrust, the compression case of push rod 6 is with fixing case, make case compress loudspeaker simultaneously and realize contiguity, can not leak gas.
