Detailed Description

The utility model is described in detail below with reference to the figures and the specific embodiments.

Referring to fig. 1 to fig. 3, in the present embodiment, the present invention provides a sound box, including: face guard 2, back lid 1, first silica gel packing ring 4, second silica gel packing ring 5, first loudspeaker group 6, second loudspeaker group 7, steel mesh 3, face guard 2 wholly is the frame form, the preceding middle part of back lid 1 forms first recess 11 and second recess 12 respectively, first recess 11 and second recess 12 are separated by the certain distance and set up, correspond respectively in first recess 11 and the second recess 12 and be equipped with the first silica gel packing ring 4 and the second silica gel packing ring 5 that the shape is imitative, the inboard of the antetheca of face guard 2 corresponds respectively first recess 11 and second recess 12 are formed with first enclosure and second enclosure, first enclosure and second enclosure correspond the embedding respectively in first recess 11 and the second recess 12 to correspond respectively and form first cavity and second cavity. The effect of first silica gel pad and second silica gel pad is realized shock attenuation and sealing effect between the recess of face guard 2 and the enclosure of back lid 1 help getting better audio. First loudspeaker group 6 includes first high pitch horn 71 and first woofer 61, second loudspeaker group 7 includes second high pitch horn 72 and second woofer 71, the antetheca punishment corresponds respectively the regional correspondence of first cavity, second cavity is equipped with the installation first loudspeaker group 6, the mounting structure of second loudspeaker group 7, the inner wall of antetheca still corresponds respectively the regional extension of first cavity, second cavity is formed with first air flue and second air flue, is used for realizing the gas exchange between first cavity, second cavity and outside air respectively. 2 departments of face guard still are equipped with plug 8, and external control line can pass through plug 8 inserts realizes the drive to loudspeaker, can the tip of first enclosure and second enclosure sets up little through-wire hole, when reducing the influence to tone quality, also realizes the electricity of circuit and loudspeaker to be connected. The steel mesh 3 is provided at the front wall.

In this embodiment, the mounted position of first woofer 61 and second woofer 71 is kept away from the middle part of audio amplifier, the mounted position of first tweeter 71 and second tweeter 72 is close to the middle part of audio amplifier reduces the influence between the woofer, helps obtaining better bass audio.
