Specific embodiment

The present invention will be further described with reference to the accompanying drawing.

As shown in Figure 1 to Figure 3, the utility model provides a kind of loudspeaker mould group, including the shell 1 with accommodation space With the loudspeaker monomer 2 being housed in shell 1.

Wherein shell 1 includes bottom wall 11, roof, the side wall 12 extended from bottom wall 11 and ceiling edge bending.11 He of bottom wall Side wall 12 surrounds accommodation space, and shell 1 further includes that accommodation space is divided into the receiving loudspeaking between the side wall 12 The spaced walls 13 of the filled cavity 20 of 2 monomer accommodating chamber 10 of device monomer and receiving sound-absorbing material.Wherein spaced walls 13 include the bottom of close to The upper surface of the lower surface of wall 11 and separate bottom wall 11, monomer accommodating chamber are arranged between bottom wall and lower surface, filled cavity setting Between spaced walls and roof.

Specifically in the present embodiment, shell 1 include the lower case 101 with bottom wall 11, with lower case 101 match be encircled into The upper housing 102 and lid of accommodation space, which connect, closes the cover board 103 of accommodating space in upper housing 102.The wherein setting of spaced walls 13 exists On upper housing 102, roof of 103 integrated injection molding of cover board on upper housing 102, as shell 1.

Further, the monomer fixing groove 110 for fixing loudspeaker monomer 2, shell 1 are provided in monomer accommodating chamber 10 On be provided with stage portion 15 for surrounding monomer fixing groove 110.Loudspeaker monomer 2 is installed close to the side of vibrating diaphragm into monomer solid Determine in slot 110, and then monomer accommodating chamber 10 is divided into the preceding operatic tunes 1001 and the rear operatic tunes 1002.The following table of vibrating diaphragm and spaced walls 13 Between face formed before the operatic tunes 1001, between loudspeaker monomer and side wall 12 formed after the operatic tunes 1002, the filled cavity 20 with it is described The operatic tunes 1002 is connected to afterwards.
