Embodiment Construction
[0046] Such as figure 1 As shown, a mobile phone receiver with a small amount of voice leakage, the number of sound holes in the receiver is n=2, the distance between the sound holes is l>10mm, and the distance between the center of the sound holes and the top of the mobile phone is d>2mm.
[0047] The method for designing the sound hole of the receiver of the mobile phone with little voice leakage includes the following steps:
[0048] Step 1, the sound column model with the number n of the sound holes of the mobile phone receiver and the length L is obtained:
[0049] Each sound hole is equivalent to a point sound source, and all the sound holes of the mobile phone receiver are distributed on a straight line to form a sound column model with a length of L, and the distance between two adjacent sound holes is l;
[0050] Such as figure 2 As shown, the sound waves radiated from the sound outlet of the receiver pass through n sound outlets to reach the composite sound pressu...
