Description
本創作涉及一種塞入式的耳機構造,特別是一種偏軸雙音域耳機。The present invention relates to a plug-in earphone construction, in particular a off-axis dual-range earphone.
多媒體影音技術的進步使得人們隨時都能欣賞高品質的多媒體影音訊息,在已知的許多影音播放裝置之中,耳機是提供音響的主要裝置之一。依據耳機的使用配戴方式,基本上可以區分為耳罩式耳機和塞入式耳機,前者為最早出現的耳機形態,雖然可以提供較為優異的音效,但其體積較大;後者具有體積輕巧及容易攜帶的優點,但是受限於發聲單體尺寸較小的條件,塞入式耳機的音效通常不及前者優異。Advances in multimedia audio and video technology have enabled people to enjoy high-quality multimedia audio and video information at any time. Among many known audio and video playback devices, headphones are one of the main devices for providing audio. According to the wearing mode of the earphone, it can be basically divided into an earmuff type earphone and a stuffing type earphone. The former is the earliest earphone form, although it can provide superior sound effect, but the volume is large; the latter has a light volume and The advantage of being easy to carry, but limited by the condition that the size of the sounding unit is small, the sound effect of the plug-in earphone is usually not as good as the former.
早期已知的塞入式耳機僅具有一個喇叭,且多為中低音域的動圈喇叭,對於高音域的音響輸出效果不佳,難以滿足使用者對於耳機在中高音域的音效要求。為了解決上述問題,一種包含中低音域喇叭以及中高音域喇叭的塞入式耳機被提出,例如已核准公告的台灣新型專利M493215「雙頻同軸耳機」,其中提出的一種雙頻同軸耳機,包括動圈式揚聲單元、蓋體及高音揚聲單元;動圈式揚聲單元包含動圈式支架及動圈式振膜,動圈式振膜位於動圈式支架;蓋體覆蓋於動圈式支架,蓋體與動圈式支架共同包圍而成調音腔體,蓋體包含至少一調聲孔,調音腔體連通於至少一調 聲孔;高音揚聲單元設置於蓋體,高音揚聲單元之一面面向於調音腔體,調音腔體位於動圈式振膜與高音揚聲單元之間。The earphones known in the early days have only one horn, and most of them are moving horns in the middle and low range. The sound output of the high range is not good enough to meet the user's requirements for the sound quality of the headphones in the middle and high range. In order to solve the above problems, a plug-in type earphone including a middle-low range speaker and a medium-high range speaker has been proposed, for example, a newly-approved Taiwanese patent M493215 "dual-frequency coaxial earphone", which has been proposed as a dual-frequency coaxial earphone, including The moving coil type speaker unit, the cover body and the high-pitched speaker unit; the moving coil type speaker unit comprises a moving coil type bracket and a moving coil type diaphragm, the moving coil type diaphragm is located on the moving coil type bracket; the cover body covers the moving coil The bracket, the cover body and the moving coil bracket are enclosed together to form a tuning cavity, the cover body comprises at least one tuning hole, and the tuning cavity is connected to at least one tone The sound hole; the high-pitched sound unit is disposed on the cover body, and one of the high-pitched sound unit faces the tuning cavity, and the tuning cavity is located between the moving coil diaphragm and the high-pitched sound unit.
前述專利技術的動圈式揚聲單元及高音揚聲單元採同軸設計,雖有利於元件的組裝,但是其中動圈式揚聲單元的聲音輸出受到高音揚聲單元的阻擋,雖有調聲孔及調音腔體可供動圈式揚聲單元產生的中低音域聲音之輸出,但是仍無法提供良好的暢通性和確保聲音傳遞之保真效果。另一方面,由於採同軸設計,其外型呈倒L型,與人體耳道及外耳道的形狀匹配性不佳,不符合人體工學之要求,且貼附性不佳而容易鬆脫。The moving coil type speaker unit and the high-pitched speaker unit of the aforementioned patented technology adopt coaxial design, which is advantageous for component assembly, but the sound output of the moving coil type speaker unit is blocked by the high-pitched sound unit, although there is a tuning hole And the tuning cavity can be used for the output of the mid-bass sound produced by the moving coil speaker unit, but still can not provide good smoothness and ensure the fidelity of sound transmission. On the other hand, due to the coaxial design, the shape is inverted L-shaped, which has poor matching with the shape of the human ear canal and the external auditory canal, does not meet the requirements of ergonomics, and is easy to loosen due to poor adhesion.
本創作的目的之一在解決已知塞入式耳機的上述問題,提出一種可以提供高品質且清晰的雙音域(中低音域及中高音域)輸出音效,並具有舒適的配戴性且不易脫落的偏軸雙音域耳機。One of the purposes of this creation is to solve the above-mentioned problems of the known plug-in earphones, and to provide a high-quality and clear dual-range (mid-low range and mid-high range) output sound, and to have comfortable wearability and is not easy.

The front casing 30 is hollow to form the front cavity C1, and the rear casing 40 is hollow to form the rear cavity C2. The front casing 30 has a front and a front. a first opening 31 communicating with the cavity C1 and the sound hole 32. The rear case 40 has a second opening 41 communicating with the rear cavity C2 and a wire opening 44 through which the wire is passed. An opening 31 can be combined with the second opening 41 of the rear case 40 to form a housing S having a cavity C. In one embodiment, the front housing 30 has a sound tube 35 for forming the sound hole 32 therein. In one embodiment, the rear housing 40 has a venting opening 42 in communication with the outside of the housing S on the back side of the first horn 10 for adjusting the internal pressure of the inner chamber C. In one embodiment, the first opening 31 of the front case 30 and the second opening 41 of the rear case 40 respectively have a rib 33 and an engaging groove 43 (the positions of the rib and the engaging groove are interchangeable), and the rib 33 The first horn 10 and the second horn 20 are fixed to the front case 30 (see FIGS. 2 and 3), and the rib 33 and the engaging groove are used. 43 The front case 30 and the rear case 40 can be easily combined, and the assembly is convenient.
在本創作的一較佳實施例,第一喇叭10置於前腔C1的軸心X1與後腔C2的軸心X2的相交位置。在一實施例中,第一喇叭10的發聲軸向與後腔C2之軸向X2平行;在一較佳的實施例,如圖2繪示,第一喇叭10的發聲軸向與後腔C2之軸向X2為同軸關係。在一實施例,第一喇叭10的發聲軸向與第二喇叭20的發聲軸向相交或不平行,第二喇叭20位於第一喇叭10靠近前腔C1的一側,較佳地,第二喇叭20位於第一喇叭10之出音方向的一側,並且第二喇叭20較第一喇叭10更靠近前腔C1的出音孔32,第二喇叭20和第一喇叭10兩者間具有一間隙G,在一實例,前殼30的前腔C1具有突起的一支 架34用於支撐及固定第二喇叭20,並且令二喇叭20和第一喇叭10兩者間具有所述間隙G。In a preferred embodiment of the present invention, the first horn 10 is placed at the intersection of the axis X1 of the front chamber C1 and the axis X2 of the rear chamber C2. In one embodiment, the vocal axis of the first horn 10 is parallel to the axial direction X2 of the rear cavity C2; in a preferred embodiment, as shown in FIG. 2, the vocal axis of the first horn 10 and the rear cavity C2 The axial direction X2 is a coaxial relationship. In one embodiment, the sound emitting axis of the first speaker 10 intersects or is not parallel with the sounding axis of the second speaker 20, and the second speaker 20 is located at a side of the first speaker 10 near the front cavity C1, preferably, the second The horn 20 is located on one side of the sounding direction of the first horn 10, and the second horn 20 is closer to the sound hole 32 of the front cavity C1 than the first horn 10, and the second horn 20 and the first horn 10 have a Gap G, in an example, the front cavity C1 of the front case 30 has a raised one The frame 34 is for supporting and fixing the second horn 20, and has the gap G between the two horns 20 and the first horn 10.
在一實施例,第一喇叭10設於前殼30的第一開口31處,第二喇叭20設於前殼30的前腔C1的偏置位置,較佳地,第二喇叭20的位置偏離第一喇叭10和出音孔32的連線,亦可以如圖2繪示,第二喇叭20的位置偏離前腔C1的軸心X1的一側。因此,第二喇叭20不會阻擋第一喇叭10的輸出,另一方面,第二喇叭20係為中高音域喇叭且較接近人耳的耳膜(因為較接近出音孔32),高音之短波輸出至耳膜空間狹小,因此可以提供高品質且清晰的中高音域聲音輸出。In one embodiment, the first horn 10 is disposed at the first opening 31 of the front case 30, and the second horn 20 is disposed at an offset position of the front cavity C1 of the front case 30. Preferably, the position of the second horn 20 is deviated. The connection between the first horn 10 and the sound hole 32 can also be as shown in FIG. 2, and the position of the second horn 20 is offset from the side of the axis X1 of the front cavity C1. Therefore, the second speaker 20 does not block the output of the first speaker 10. On the other hand, the second speaker 20 is a mid-high range speaker and is closer to the eardrum of the human ear (because it is closer to the sound hole 32), and the high-pitched short wave The narrow output to the eardrum provides high quality and clear mid-high range sound output.
請參閱圖4及圖5,為本創作的另一實施例的構造分解圖及其斷面構造圖。如圖4及圖5所繪示,其中還包括一軟質耳套50(可為矽膠質的軟性耳套)和一防塵網51,軟質耳套50可套設於導音管35,藉由軟質耳套50能與人體耳道及外耳的形狀適配,具有舒適的配戴性,防塵網51設於出音孔32用以防止灰塵或異物進入內腔C。4 and FIG. 5 are exploded structural views and cross-sectional structural views of another embodiment of the present invention. As shown in FIG. 4 and FIG. 5 , the soft ear cover 50 (which can be a soft rubber earmuff) and a dustproof net 51 can be included. The soft ear cover 50 can be sleeved on the sound guiding tube 35, and is soft. The ear cover 50 can be adapted to the shape of the human ear canal and the outer ear, and has a comfortable wearing property. The dustproof mesh 51 is disposed in the sound hole 32 to prevent dust or foreign matter from entering the inner cavity C.
