In some embodiments, through hole 112a can be the U-shaped hole of one end open, it is also possible to be the circular hole or rectangular opening closed.
Being appreciated that in other embodiments, through hole 112a is arranged also dependent on actual requirement, and is not limited to embodiments discussed above.
In some embodiments, groove 108 includes the first end 108a and the second end 108b being positioned at length direction two ends, and the first end 108a connects with through hole 112a, and the second end 108b connects with outward leakage hole 110.
So, reveal pipe 106 and can connect sound chamber 104 and the outside of casing 102.
Being appreciated that in other embodiments, the connected mode revealing the outside that pipe 106 connects sound chamber 104 and casing 102 is arranged also dependent on actual requirement, and is not limited to embodiments discussed above.
In some embodiments, groove 108 includes the second ditch groove 108d of the first groove 108c and casing 102 ft connection connected with sound chamber 104 and is connected the first groove 108c and the 3rd groove 108e of the second groove 108d；
The axis of the first groove 108c and the axis of the 3rd groove 108e are substantially vertical, and the second groove 108d and the 3rd groove 108e is substantially parallel；
Arc groove is all used to connect between first groove 108c and the 3rd groove 108e and the second groove 108d and the 3rd groove 108e.
So, improve the most less noise of sound deadening capacity of medium-high frequency sound wave, and then make the leakage pipe 106 be obtained in that preferable bass effect.
Being appreciated that in other embodiments, the connected mode between shape and groove 108 corner of groove 108 is arranged also dependent on actual requirement, and is not limited to embodiments discussed above.
In some embodiments, groove 108 each shape of cross section along its length and size are essentially identical.
So, prevent cross section sudden change from causing the decay of low-frequency sound wave, it is ensured that to reveal pipe 106 and be obtained in that preferable bass effect.
Being appreciated that in other embodiments, the shape in groove 108 cross section is arranged also dependent on actual requirement, and is not limited to embodiments discussed above.
