As shown in Figures 4 to 6, in 100 1 embodiment of electroacoustic component of the present invention, regulating part 50 is rotationally connected with shell
10, to rotate the size of adjustment leak 13b.
That is, regulating part 50 is installed on the housing 10 by the way of rotation, when regulating part 50 occurs to turn relative to shell 10
It is used to block the part of leak 13b when dynamic, on regulating part 50 and the relative positional relationship of leak 13b changes, thus
Realize the adjustment of leak 13b size.
It should be understood that regulating part 50 is arranged in this manner, regulating part 50 can be fixed on the housing 10 certain
Without moving along 10 surface of shell at one position, leak can be realized by relying solely on itself rotation in original place
The opening and closing of 13b；In this way, not only can the effective area occupied of economization regulating part 50 on the housing 10, can also effectively promote regulating part
50 setting stability and stability in use.
