Abstract

The utility model provides a loudspeaker mesh enclosure used for being assembled at a sound outlet of a portable electronic device. The loudspeaker mesh enclosure comprises a sheet body and a plurality of through-holes penetrating through the sheet body. Diameters of the through-holes are from 0.12-0.33mm, so sound generated by a loudspeaker can be smoothly transmitted through the fine and closely woven through-holes of the loudspeaker mesh enclosure, and influences such as volume reduction or sound effect distortion caused by blocking of the loudspeaker mesh enclosure can be reduced, and most of dusts or foreign matters are blocked outside the portable electronic device, and thereby purposes of sound transmission quality improvement and inner loudspeaker protection can be achieved.

Description

The guard of loud speaker

Technical field

The utility model is involved in a kind of guard of loud speaker, relates in particular to a kind of guard that is installed in the sound mouth of portable electronic devices.

Background technology

Common portable electronic devices (such as mobile phone etc.) inside is provided with loud speaker, and it passes for generation of sound and by the sound mouth on the portable electronic devices; Wherein, this sound mouth generally is equiped with lays pertusate guard; by these holes the sound that this loud speaker produces is gone out extraneous and people's ear by internal delivery; and intercept simultaneously dust or foreign matter enters portable electronic devices inside by this sound mouth, and then reach the loud speaker of protection portable electronic devices inside or the effect of other intraware.

In the prior art, this guard mainly is to utilize the mould punching sheet metal made or to reticulate structure by metal wire knitted made, so that this guard has a plurality of holes.Yet, in the guard of existing loud speaker, because the spacing between these holes is excessive, and causes the transmission of sound to be obstructed or absorb, so that the wave volume that produces of loud speaker is lowered originally, and may affects tonequality or make the audio distortion; In addition, in the guard of existing loud speaker, the diameter of these holes or oversize, and cause dust or the foreign matter of extraneous part to enter the inside of portable electronic devices by these holes, and then cause the damage of loud speaker or other intraware.

Therefore, the guard of the loud speaker of existing portable electronic devices has wave volume and the tonequality susceptible to maybe can't be protected the disappearances such as loud speaker or other intraware.

Summary of the invention

The purpose of this utility model is to provide a kind of guard of loud speaker, be used for being installed in the sound mouth of portable electronic devices, be blocked and reduce volume or cause the impact such as audio distortion and reduce sound that the portable electronic devices internal loudspeaker produces by perforation fine and closely woven on the guard, and dust or foreign matter can be isolated from outside the portable electronic devices.

For reaching above-mentioned purpose, the utility model provides a kind of guard of loud speaker, is used for being installed in the sound mouth of portable electronic devices, and this guard comprises: a lamellar body; And a plurality of perforations, it is arranged in this lamellar body, and respectively the diameter of this perforation is 0.12 to 0.33mm.。

In the above-mentioned guard, these perforations centre-to-centre spacing each other is 0.19 to 0.5mm.

In the above-mentioned guard, the minimum spacing at these perforations edge each other is 0.07 to 0.18mm.

In the above-mentioned guard, this lamellar body comprises a plastic layer and a metal level, and this metal level is arranged on this plastic layer.

In the above-mentioned guard, any three adjacent one another are is to arrange with three summits of an equilateral triangle in these perforations.

In the above-mentioned guard, these perforations are arranged and are formed multiple row parallel lines, and in these perforations any four adjacent one another are be to arrange with four summits of a rectangle.

In the above-mentioned guard, this plastic layer is the laminar layer body of PETG (PET) or Merlon (PC).

Therefore; the transmission sound that the guard of the utility model loud speaker can make by fine and closely woven perforation loud speaker produce reaches in people's ear to portable electronic devices; and reduce that sound is stopped by net cover structure and volume decay or cause the impact such as audio distortion; and most dust or foreign matter can be intercepted outside portable electronic devices, and reach simultaneously the quality that promotes transmission sound and the purpose of protecting internal loudspeaker.

Embodiment

For fully understanding the purpose of this utility model, feature and effect, now by following specific embodiment, and cooperate accompanying drawing, the utility model is described in detail, illustrate as after:

Please refer to Figure 1 and Figure 2, Fig. 1 is the schematic diagram that the guard of loud speaker among the utility model the first embodiment is applied to portable electronic devices; Fig. 2 is the enlarged diagram of A part among Fig. 1; The guard 1 of the utility model embodiment loud speaker is used for being installed in the sound mouth 110 of portable electronic devices 100, this guard 1 comprises a lamellar body 10 and a plurality of perforation 20, these perforations 20 are arranged in this lamellar body 10, respectively the diameter D of this perforation 20 is 0.12 to 0.33mm, in a preferred embodiment, respectively the diameter D of this perforation 20 is 0.15 to 0.30mm, accordingly, the guard 1 of the utility model the first embodiment has many undersized perforations 20, and the sound that is used for allowing portable electronic devices 100 internal loudspeaker produce is passed to outside and people's ear by these perforations 20.

As shown in Figure 2, among the utility model the first embodiment, any three adjacent one another are is to arrange with three summits of an equilateral triangle in these perforations 20, it is the configuration of these perforations 20 formation arrangement interlaced with each other of adjacent craspedodrome or line, and these perforations 20 centre-to-centre spacing C each other is 0.19 to 0.5mm, arranges and can form fine and closely woven perforation 20 at this lamellar body 10.In addition, the minimum spacing B at these perforation 20 edges each other is 0.07 to 0.18mm, in a preferred embodiment, the minimum spacing B at these perforation 20 edges each other is 0.1 to 0.15mm, and can form finer and close perforation 20 at this lamellar body 10, intercept the impact that sound wave transmits to reduce guard 1 structure.

In the guard of the present utility model, this lamellar body 10 can be the material of metal or plastics, and forms perforation 20 by modes such as punching or laser drillings; In addition, as shown in Figure 3, it is the guard of loud speaker among the utility model the first embodiment generalized section along b-b in Fig. 2, as shown in the figure, this lamellar body 10 comprises a plastic layer 12 and a metal level 11, and this metal level 11 is arranged on this plastic layer 12, and this plastic layer 12 can be the laminar layer body of PETG (PET) or Merlon (PC), and this metal level 11 can for example be metal coating, when being installed in the sound mouth 110 (Fig. 1) of portable electronic devices 100 when guard 1, this metal level 11 toward the outer side, and make guard 1 have the effect of metallic luster sense by this metal level 11, and can be that the cost of guard of metal material is lower compared to integral body.

Please refer to Fig. 4; it is the schematic diagram of the guard of loud speaker among the utility model the second embodiment; what be different from the first embodiment is; these perforations 20 are to arrange to form the multiple row parallel lines; and any four adjacent one another are is to arrange with four summits of a rectangle in these perforations 20; namely respectively this perforation 20 is to arrange alignedly with other adjacent on every side perforation 20; these perforations 20 centre-to-centre spacing C each other is 0.19 to 0.5mm; and; the minimum spacing B at these perforation 20 edges each other is 0.07 to 0.18mm; in a preferred embodiment; the minimum spacing B at these perforation 20 edges each other is 0.1 to 0.15mm; and can form finer and close perforation 20 at this lamellar body 10, be beneficial to the transmission of sound wave and reach effects such as protecting portable electronic devices 1 internal loudspeaker.
