The features of the following examples and embodiments can be supplemented or combined with each other without conflict.

Referring to fig. 1, a terminal handset 100 according to an embodiment of the present disclosure may be applied to a terminal 200 and disposed inside the terminal 200, for details. The terminal earpiece 100 includes a speaker assembly 10 and a dust assembly 20.

The speaker assembly 10 includes a housing 11 and a speaker unit 12 accommodated in the housing 11, and a sound outlet 13 is provided on a side surface of the housing 11. In the example shown in the figure, the housing 11 includes a first housing 111 and a second housing 112 that are spliced together, a receiving space having an opening 113 is formed inside the first housing 111, and the horn unit 12 is received and fixed in the first housing 111 from the position of the opening 113, thereby enclosing the horn rear cavity 30 with the first housing 111. The second casing 112 surrounds the outer side of the side wall of the first casing 111 on which the opening 113 is provided, and encloses the horn front cavity 40 with the horn unit 12 and a part of the first casing 111 (i.e. the side wall of the first casing 111 on which the opening 113 is provided), and the side surface of the second casing 112 is provided with the sound outlet 13. The side of the front horn cavity 40 close to the sound outlet 13 is horn-shaped.

In an alternative embodiment, the horn assembly 10 further includes a horn magnetic steel 14 and a heat conducting glue 15, the horn magnetic steel 14 is disposed on a side surface of the horn unit 12 away from the second casing 112, and the heat conducting glue 15 is disposed on the horn magnetic steel 14 and connected to a side surface of the first casing 111. The heat conducting glue 15 can lead out heat in time, and the loudspeaker assembly 10 is prevented from being damaged due to overhigh temperature.

The dust-proof assembly 20 covers the sound outlet 13, the dust-proof assembly 20 comprises a dust-proof net 21 and an adsorption piece 22 for adsorbing liquid substances, and the adsorption piece 22 is attached to the dust-proof net 21. The dust screen 21 is made of hydrophobic and oleophobic material, such as Sefar 75-19BSY, or is processed by special process to achieve hydrophobic and oleophobic effects, so as to avoid adsorption of impurities such as liquid and grease. The adsorption member 22 is made of hydrophilic and lipophilic materials, and can effectively adsorb impurities such as liquid and grease. In practical applications, the terminal earpiece 100 often fails in silence, quiet sound, noise, etc., and most of the reasons are that in a natural state, liquid and grease may be absorbed and permeate through the dust screen 21, and after a period of time, the liquid and grease may accumulate and solidify on the dust screen 21, resulting in the blockage of the sound outlet 13. In the embodiment, the hydrophobic and oleophobic dust screen 21 and the hydrophilic and oleophilic adsorption part 22 are combined, and the adsorption part 22 can adsorb impurities more effectively than the dust screen 21, so that the dust screen 21 is prevented from being blocked by solidification of liquid, grease and the like.

In an alternative embodiment, the dust screen 21 is covered with a water-proof coating. In another alternative embodiment, the dust screen 21 is covered with a p2i nm waterproof coating, although the dust screen may be manufactured using other hydrophobic and oleophobic processes, and the disclosure is not limited thereto.

Furthermore, the dust screen 21 covers the sound outlet 13, and the adsorbing member 22 is attached to the dust screen 21, that is, the adsorbing member 22 is located on the side far away from the sound outlet 13. When impurities such as liquid and grease enter the terminal receiver 100, the adsorbing member 22 may adsorb the liquid and grease in advance, so as to prevent the dust screen 21 from being clogged by the solidification of the liquid and grease.

In an optional embodiment, the adsorbing member 22 is detachably attached to the dust screen 21, and when the adsorbing member 22 absorbs more impurities such as liquid, grease, etc., the adsorbing member 22 may be replaced with a new adsorbing member 22, which is helpful to clean the terminal handset 100 and prolong the service life of the terminal handset 100.

In an optional embodiment, the area of the absorbing member 22 is smaller than the area of the dust screen 21, so as to ensure that the sound emitted from the speaker unit 12 is transmitted out through the sound outlet 13 and the dust screen 21, and is not completely blocked by the absorbing member 22, and meanwhile, the requirements of dust prevention and blocking prevention are met.

In an alternative embodiment, the ratio of the area of the absorbing member 22 to the area of the dust screen 21 is not less than 50%. So as to adsorb and store more impurities such as liquid, grease and the like. Of course, the area ratio of the absorbing member 22 to the dust screen 21 can be any value, and can be specifically arranged according to the practical application.

Further, the adsorbing member 22 is provided with a plurality of hollow parts 221, the hollow parts 221 enable sound to be transmitted from the sound outlet 13 and the dust screen 21, and the area of the hollow parts 221 is not less than 10mm²To ensure that the sound is not completely blocked, of course, in other embodiments, the area of the hollow portion 221 may be any size, and may be specifically set according to the actual application.

In an alternative embodiment, the plurality of hollow-out portions 221 are disposed at intervals along the length direction of the dust screen 21. In another alternative embodiment, the hollow-out portions 221 are disposed axially symmetrically along the length direction of the dust screen 21. So that sound is uniformly emitted from the sound outlet 13.

In yet another alternative embodiment, the hollow-out portion 221 is disposed to be distributed mainly on the central axis of the absorbing member 22 to avoid the sound outlet 13 as much as possible, so as to reduce the influence of the absorbing member 22 on the acoustic performance.
