[ detailed description ] embodiments

The present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1 to 3, a speaker 100 includes a housing 1 having an accommodating cavity 101 and a sound generating unit 2 accommodated in the accommodating cavity 101, wherein a leakage hole 20 is formed in a side wall of the sound generating unit 2, the speaker 100 further includes an adjusting member 3 attached to the sound generating unit 2 and covering the leakage hole 20, the adjusting member 3 includes a frame body and a mesh installed in the frame body, the mesh is opposite to the leakage hole 20, and the mesh is used for adjusting a leakage amount of the leakage hole 20.

The frame is preferably made of a hard material. Compare in current through buckling and inhale the cotton package of sound and cover the mode of revealing the volume of hole 20 with adjustment sound production monomer 2, in this embodiment, establish the volume of revealing of 3 adjustment sound production monomers 2 of regulating part through setting up the subsides, regulating part 3 include the framework with install in the screen cloth 32 of framework is in the aspect of the volume of revealing of adjusting sound production monomer 2, and the framework is in comparison in inhaling the cotton easier installation of sound, the manual operation of being convenient for moreover.

It should be noted that the leakage amount of the sounding unit 2 can be adjusted by attaching mesh fabrics with different mesh numbers to the frame body.

Preferably, the leakage holes 20 are provided with two and two the leakage holes 20 are respectively arranged at two opposite sides of the sounding single body 2, the adjusting member 3 is provided with two corresponding to the two leakage holes 20, and each of the leakage holes 20 covers one of the adjusting member 3. Thus, the adjusting piece 3 is further convenient to adjust the leakage amount of the sounding unit 2.
