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...

Abstract

The invention provides a mobile phone receiver and a designing method thereof. The designing method is mainly characterized by comprising the following steps of: carrying out equivalence on each sound emitting hole to form a point sound source, wherein all receiver sound emitting holes are distributed on a straight line to form a sound column model with the length of L; synthesizing sound pressure by enabling sound waves radiated from the receiver sound emitting holes to reach a position p point through the receiver sound emitting holes, and obtaining an optimal number of the receiver sound emitting holes, two, according to a sound voltage superposition and directive mathematic formula, wherein the interval between two sound emitting holes is larger than 10mm; and in a dead room, carrying out sound leakage test by utilizing an audio tester to test sound leakage amount receiving frequency response curve and receiving loudness to obtain the result that the distance between the central of each sound emitting hole and the top of a mobile phone is larger than 2mm so as to control sound leakage amount. According to the invention, the problem of sound leakage of the receiver sound emitting holes of the mobile phone is remarkably improved so as to protect the privacy of persons.

Description

technical field [0001] The invention belongs to the technical field of mobile terminal equipment, and in particular relates to a sound outlet of a mobile phone receiver with a small amount of voice leakage. The invention also relates to the design method of the mobile phone receiver. Background technique [0002] At present, the mobile phones on the market have different degrees of voice leakage during a call. Especially when the external environment is relatively quiet, the phenomenon of voice leakage from the sound hole of the receiver is particularly obvious, and the people next to it can clearly hear the content of the conversation. From the perspective of protecting call privacy, this kind of leakage is not allowed. In the prior art, the problem of voice leakage through the sound hole of the mobile phone receiver has not been effectively solved. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings i...
