Description
本發明係有關於耳機，特別是一種耳機殼體的結構改良，其具有一排水通道連通耳機的透氣孔，藉以快速排除水分，避免損壞揚聲器且能提升耳機的聲學表現與性能。 The invention relates to an earphone, in particular to a structural improvement of an earphone housing, which has a drainage channel connecting the vent hole of the earphone, thereby quickly removing moisture, avoiding damage to the speaker and improving the acoustic performance and performance of the earphone.
耳機的透氣孔通常是設置於殼體的後側，當耳機的揚聲器發聲時，透氣孔連同覆蓋透氣孔的防水透氣部調節了耳機背腔內氣體的進出量，其不僅能夠減少背腔中氣體的壓強，並且一定程度地影響到耳機的聲學表現與性能，特別是在耳機的低頻段的頻率響應上。 The venting hole of the earphone is usually disposed on the rear side of the casing. When the speaker of the earphone emits sound, the venting hole and the waterproof venting portion covering the venting hole adjust the amount of gas in and out of the back cavity of the earphone, which can not only reduce the gas in the back cavity. The pressure, and to a certain extent, affects the acoustic performance and performance of the headphones, especially in the frequency response of the low frequency band of the headphones.
傳統的耳機，例如美國第4646872號專利，請參考其第2圖。(以下說明是沿用上述專利所使用之元件編號)耳機具有一外殼2，外殼2的內部具有一容置空間以容置揚聲器1。外殼2的後端另具有一通道7連通後蓋9的一開孔，使得背腔8中的氣體能夠與外界流通，而為了防止水分進入背腔8，此專利設置了一具有防水效果的通氣網10來覆蓋後蓋9的開孔。此外，此專利對於浸水後或是潑水後耳機的頻率響應作了一連串的測試，請參考其第6圖與第7圖，從圖中可以看到，當耳機在浸在水中後或是潑水後擦乾耳機的水分時，耳機在低頻段的頻率響應上均有一定程度的下降，並且隨著時間的增加而低頻段的增益逐漸恢復至原先未浸水或是未潑水時的情 況。 Conventional earphones, such as U.S. Patent No. 4,464,872, please refer to FIG. (The following description is based on the component number used in the above patent.) The earphone has a casing 2 having an accommodating space for accommodating the speaker 1. The rear end of the outer casing 2 further has a passage 7 communicating with an opening of the rear cover 9, so that the gas in the back chamber 8 can circulate with the outside, and in order to prevent moisture from entering the back chamber 8, the patent provides a waterproofing effect. The mesh 10 covers the opening of the back cover 9. In addition, this patent has made a series of tests on the frequency response of headphones after immersion or after splashing water. Please refer to Figure 6 and Figure 7. It can be seen from the figure that when the headphones are immersed in water or splashed with water, When the moisture of the earphone is dried, the frequency response of the earphone in the low frequency band is reduced to some extent, and as the time increases, the gain of the low frequency band gradually returns to the condition that the original is not soaked or not splashed. condition.
雖然從上述專利中可以看出水份對於耳機的影響，然而，上述專利在其耳機的設計中缺乏一適當的排水機制，使得耳機在浸水後或是潑水後無法快速地排除水分，而無法快速地提升到原先未潑水或未浸水時耳機在低頻段的頻率響應，因此傳統的耳機尚有改進的地方。 Although the influence of moisture on the earphone can be seen from the above patent, the above patent lacks an appropriate drainage mechanism in the design of the earphone, so that the earphone cannot quickly remove moisture after being immersed in water or after splashing water, and cannot be quickly The ground is raised to the frequency response of the earphones in the low frequency range when the water is not splashed or unimmersed, so the conventional earphones have some improvement.
有鑑於此，本發明之主要目的在於提供一種耳機，其可快速地排除水分，避免水分進入到耳機本體內部損壞揚聲器並且能快速地提升耳機在低頻段的頻率響應。 In view of this, the main object of the present invention is to provide an earphone that can quickly remove moisture, prevent moisture from entering the inside of the earphone body, damage the speaker, and can quickly increase the frequency response of the earphone in the low frequency band.
為了達成上述目的，本發明提供了一種設有排水通道的耳機，其包含有一本體與一防水透氣部。其中本體內部具有一容置空間以設置一揚聲器，揚聲器向後將容置空間區隔出一背腔，且本體內部設有一排水通道連通位於本體外表面的一第一開口與一第二開口，以及一透氣孔連通排水通道與背腔；防水透氣部則形成於透氣孔上。 In order to achieve the above object, the present invention provides an earphone provided with a drainage channel, which comprises a body and a waterproof gas permeable portion.

A back cavity 231 is defined in the 23rd portion, and a through hole 28 is defined in the bottom of the housing 22. The through hole 28 is used for other components (not shown) such as a bass tube or a sound source line.
殼體22後側具有一排水通道26連通位於頂部的第一開口24與位於底部的第二開口25；此外，排水通道26藉由殼體22內部的一透氣孔27與背腔231相連通，使背腔231內的氣體可以經由透氣孔27而從第一開口24及/或第二開口25散出。其中，排水通道26可進一步區分為相互連通的一彎折段261與一直線段262分別從殼體22後側的外表面向內凹入而成，彎折段261概呈L字形，其一端連通第一開口24並且在轉角處連通透氣孔27，使 第一開口24與透氣孔27可直線相通，直線段262則連通第二開口25(如第1圖)。此外，本實施例在殼體22的後側設有了一後蓋40以覆蓋殼體22後側的外表面。值得一提的是，後蓋40亦可一體成型於殼體22，因此並非實施本發明的必要元件，而且第二開口25亦可改設於該後蓋40上，並不會影響排水通道26的功能。 The rear side of the housing 22 has a drain passage 26 communicating with the first opening 24 at the top and a second opening 25 at the bottom. Further, the drain passage 26 communicates with the back chamber 231 through a venting hole 27 inside the housing 22, The gas in the back chamber 231 can be dissipated from the first opening 24 and/or the second opening 25 via the vent hole 27. Wherein, the drainage channel 26 can be further divided into a bending section 261 and a straight section 262 which are mutually communicated from the outer surface of the rear side of the casing 22, and the bending section 261 is substantially L-shaped, and one end thereof is connected. An opening 24 and communicating with the venting opening 27 at the corner, so that The first opening 24 is in line communication with the venting opening 27, and the straight section 262 is in communication with the second opening 25 (as shown in FIG. 1). Further, the present embodiment is provided with a rear cover 40 on the rear side of the casing 22 to cover the outer surface of the rear side of the casing 22. It is worth mentioning that the rear cover 40 can also be integrally formed on the housing 22, so that it is not an essential component of the present invention, and the second opening 25 can also be modified on the rear cover 40 without affecting the drainage channel 26. The function.
防水透氣部30是由複數個孔徑小於該透氣孔27之通孔所組成，或由至少一層不銹鋼金屬網、透氣聚氨酯(Polyurethane，PU)膜或聚酯材料所組成，其中該防水透氣部30是形成於該透氣孔27上，藉以能夠讓背腔231內的氣體散出，同時防止外部的水分進入背腔231，使耳機1在聲音的低頻段能有較佳地表現。 The waterproof venting portion 30 is composed of a plurality of through holes having a smaller hole diameter than the vent hole 27, or is composed of at least one layer of stainless steel metal mesh, a urethane (PU) film or a polyester material, wherein the waterproof venting portion 30 is It is formed on the vent hole 27, so that the gas in the back chamber 231 can be dissipated while preventing external moisture from entering the back chamber 231, so that the earphone 1 can be better expressed in the low frequency band of sound.
使用上，當水分沒有經由第一開口24而進入排水通道26時，背腔231中的氣體可以從透氣孔27經由排水通道26而流通至耳機1外部，讓耳機1的揚聲器10發聲時，能夠適時地減少背腔231中氣體的壓力，提升耳機1的低頻聲學表現與性能。由於本實施例讓第一開口24與透氣孔27為直線相通，因此可以讓背腔231的氣體輕易地散出。 In use, when moisture does not enter the drain passage 26 via the first opening 24, the gas in the back chamber 231 can flow from the vent hole 27 to the outside of the earphone 1 via the drain passage 26, so that when the speaker 10 of the earphone 1 sounds, The pressure of the gas in the back cavity 231 is reduced in time to improve the low frequency acoustic performance and performance of the earphone 1. Since the first opening 24 and the vent hole 27 are in straight line communication, the gas of the back cavity 231 can be easily dissipated.
在下雨或是使用者在運動時，雨水或是汗水等水分有可能經由第一開口24而進入排水通道26中。此時防水透氣部30阻止了水分進入背腔231，排除在防水透氣部30外部的水分則可以藉由排水通道26而快速地排出於耳機1外部，因此不僅能避免水分進入到耳機本體內部而損壞揚聲器10，並且能將耳機1在低頻段的頻率響應恢復至原先水份未進入排水通道26時的增益，提升耳機1的聲學表現與性能。 When it is raining or when the user is exercising, moisture such as rain or sweat may enter the drainage channel 26 through the first opening 24. At this time, the waterproof venting portion 30 prevents moisture from entering the back cavity 231, and the moisture excluded from the waterproof venting portion 30 can be quickly discharged to the outside of the earphone 1 by the drain passage 26, thereby not only preventing moisture from entering the inside of the earphone body. The speaker 10 is damaged, and the frequency response of the earphone 1 in the low frequency band can be restored to the gain when the original moisture does not enter the drainage channel 26, and the acoustic performance and performance of the earphone 1 are improved.
須說明的是，本領域技術人員可視實際需要在殼體22上增設 第三開口或是更多開口以加速排水之進行。另外，第一開口24與第二開口25也不一定非得設置在殼體22後端的頂部與底部，其亦可設置在殼體22的其它位置，只要透氣孔27與第一開口24或第二開口25之間的路徑使背腔231中的氣體能夠順利地與外部流通者皆可。 It should be noted that those skilled in the art may add additional components to the housing 22 as needed. The third opening or more openings to accelerate the drainage. In addition, the first opening 24 and the second opening 25 are not necessarily provided at the top and bottom of the rear end of the housing 22, and may be disposed at other positions of the housing 22 as long as the venting hole 27 and the first opening 24 or the second The path between the openings 25 allows the gas in the back chamber 231 to be smoothly circulated to the outside.
最後，必須再次說明的是，本發明於前述實施例中所揭露的構成元件僅為舉例說明，並非用來限制本案之範圍，舉凡其他易於思及的結構變化，或與其他等效元件的替代變化，亦應為本案之申請專利範圍所涵蓋。 Finally, it must be noted that the constituent elements disclosed in the foregoing embodiments of the present invention are merely illustrative and are not intended to limit the scope of the present invention, and other structural changes that are easily conceivable, or alternatives to other equivalent elements.
