Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.

The orientation concept occurring in this utility model embodiment, for example, before, below, below etc., all with mega bass sound Case normal using when placement state determine.

As depicted in figs. 1 and 2, a kind of sub-woofer of the present utility model, including bass casing 1 with located at bass box The speaker 2 of the inside of body 1, the surrounding of speaker 2 is additionally provided with paraphase structure 3, paraphase structure 3 include multi-disc interphase distribution every Soundboard 31；One end of a piece of baffle in adjacent two panels baffle 31 is connected with the front panel 12 of bass casing 1, the other end with Rear board 13 forms the first opening 32；One end of another baffle is connected with the rear board 13 of bass casing 1, the other end with front Panel 12 forms the second opening 33.

Wherein, speaker 2 is super-thin speaker, and paraphase structure 3 is designed using labyrinth type principle, thus realizing Under the conditions of less box sizes, sub-woofer is also capable of the purpose of the bass effect of shock；Speaker 2 and sound insulation Plate 31 is all on the lower panel 11 of bass box body 1.

Preferably, paraphase structure 3 includes the baffle 31 of two panels interphase distribution；Near the baffle 31 of speaker 2 one End is connected with the front panel 12 of bass casing 1, and the other end forms the first opening 32 with rear board 13；Another away from speaker 2 One end of piece baffle 31 is connected with the rear board 13 of bass casing 1, and the other end forms the second opening 33 with front panel 12；Two panels Space between baffle 31 and the first opening 32 are connected with the second opening 33, thus constituting sub-woofer Paraphase sound channel 34；Design baffle 31 in this way thus forming mazy paraphase structure 3, mazy paraphase structure 3 For being strengthened to low-frequency sound and being expanded.

As shown in Fig. 2 the quantity of mazy paraphase structure 3 is 2,2 paraphase structures 3 are symmetrically distributed in speaker 2 The left and right sides, the bass casing 1 being formed has stronger intensity, can carry television set as base, with maximum limit The use space in family is saved on degree ground.As shown in figure 3, paraphase structure 3 also includes paraphase hole 35, paraphase hole 35 is located at bass box On the rear board 13 of body 1, opening paraphase hole 35 backward not only can ensure that sub-woofer faces the attractive in appearance of face, acceptable Avoid airflow noise abnormal sound.

Bass casing 1 carries out Expanding design to casing in the depth direction using equivalent volume method, so that after design Casing not only meets necessary tank-volumes, and makes the casing after design more mate Soundbar bar-shaped acoustic device；This kind of method The bass casing 1 of design forming is flat ultrathin type cuboid, and enclosure size is less, can save family to greatest extent In use space.

The bottom of bass casing 1 is provided with bearing 5.Bearing 5 can for silica gel callosity or other have anti-skidding, anti- Hit, callosity that the environmental and durable material of shockproof, noise reduction and other effects is made, to ensure that speaker 2 will not brush up against table top in vibration.

Ramp 6 for connecting speaker 2 is additionally provided with the rear board 13 of bass casing 1.

To sum up, a kind of sub-woofer provided by the utility model, by using equivalent volume method and in depth side Upwards casing is expanded, make sub-woofer when meeting necessary tank-volumes moreover it is possible to realize less casing chi Very little；Then, extra-thin speaker 2 and mazy paraphase structure 3 are adopted in the casing of this reduced size, thus realizing shaking The purpose of the bass effect shaken；

Simultaneously as paraphase structure 3 is designed according to labyrinth type principle, the structure of bass casing 1 is specifically stronger strong Degree, so that this sub-woofer can carry television set as base, to save the use in family to greatest extent Space.

The above is only preferred implementation of the present utility model it is noted that ordinary skill people for the art Member for, on the premise of without departing from this utility model know-why, can also make some improve and replace, these improve and Replace and also should be regarded as protection domain of the present utility model.
