本發明係有關於一種配戴舒適、使用方便的小型開孔式骨傳導耳機。The invention relates to a small open-hole bone conduction earphone which is comfortable to wear and convenient to use.
作為耳機，一般大致分成插入外耳道內從而塞住耳朵的傳統式耳機、同樣塞住耳朵的骨傳導式耳機，以及有別於此之不插入外耳道內也能使用的骨傳導耳機。As the earphone, it is generally divided into a conventional earphone that is inserted into the external auditory canal to plug the ear, a bone conduction earphone that also plugs the ear, and a bone conduction earphone that can be used without being inserted into the external auditory canal.
前者的耳機有譬如文獻1(磁性耳機)和文獻2(壓電式)者。The earphones of the former are as described in document 1 (magnetic earphones) and document 2 (piezoelectric type).
後者的耳機則有譬如文獻3(所謂外罩式)者。The latter's headphones are similar to those in the literature 3 (so-called cover type).
習知之前者耳機使用時要插入外耳道內。從而，由於外耳道被堵塞，會使外耳道受壓迫，長時間使用會產生不適感，且由於不通氣，會導致出汗而感覺不適，又由於與外界隔絕，會導致孤獨感，造成精神和肉體上的負擔，並且當發生危險時聽不到警報聲，缺少安全性。It is customary to insert the earphone into the external auditory canal when using it. Therefore, because the external auditory canal is blocked, the external auditory canal is compressed, and the use of the ear can cause discomfort for a long time, and because it is not ventilated, it may cause sweating and feel uncomfortable, and it may cause loneliness due to isolation from the outside world, resulting in mental and physical body. The burden, and when the danger occurs, no alarm sounds, lack of security.
而在使用後者的耳機時，無須插入外耳道，而是與頭部接觸或抵靠在耳朵周圍使用。因而不會像前者的耳機那樣壓迫外耳道。When using the latter earphones, it is not necessary to insert the external auditory canal, but to contact the head or to abut against the ear. Therefore, the external auditory canal is not pressed like the earphone of the former.

然而，後者的耳機要將耳機設在由彈性構件構成的耳機頭環的吊架部分的兩端部，且要將耳機頭環配戴在頭部使用，因此零件數量多，組裝複雜，費用也大幅提高。由於配戴裝置大型且有重量，因此需要體力，而且配戴時頭部受到壓迫，會導致重壓感，長時間配戴容易疲勞。不用時還需要有存放場所等等，問題很多。However, the latter earphones are provided with the earphones at both ends of the hanger portion of the earphone head ring composed of elastic members, and the earphone head ring is worn on the head, so that the number of parts is large, the assembly is complicated, and the cost is also A substantial increase. Since the wearing device is large and has a heavy weight, it requires physical strength, and the head is pressed when worn, which causes a feeling of heavy pressure and is prone to fatigue for a long time. When you don't need it, you need to have a storage place, etc. There are many problems.

圖中1是譬如由矽橡膠、合成橡膠等彈性構件構成的殼體，該殼體1由插入外耳道內的大致圓筒狀的圓筒部1a、和形成於該圓筒部1a的一側外端部的外周且具有一定壁厚的大致圓板狀凸緣部1b所構成。使用時圓筒部1a被插入外耳道，且凸緣部1b也同樣被插入外耳道。作為殼體的材質，選擇振動傳遞效率好之材質、硬度。In the figure, 1 is a casing made of an elastic member such as ruthenium rubber or synthetic rubber, and the casing 1 is formed by a substantially cylindrical cylindrical portion 1a inserted into the external auditory canal and a side formed on the side of the cylindrical portion 1a. The outer periphery of the end portion is formed by a substantially disk-shaped flange portion 1b having a constant wall thickness. In use, the cylindrical portion 1a is inserted into the external auditory canal, and the flange portion 1b is also inserted into the external auditory canal. As the material of the casing, the material and hardness with good vibration transmission efficiency are selected.
在圓筒部1a的外周被覆著第1(b)圖所示的大致圓筒狀的襯墊2。該襯墊2由軟質的彈性部件構成，由於外耳道的形狀因人而異，因此當骨傳導耳機插入外耳道時，襯墊部分會發生變形並發揮緊貼作用。凸緣部1b也由可變形的彈性構件構成。當然，也可使圓筒部1a與襯墊2形成為一體。The substantially cylindrical spacer 2 shown in Fig. 1(b) is covered on the outer circumference of the cylindrical portion 1a. The pad 2 is composed of a soft elastic member. Since the shape of the external auditory canal varies from person to person, when the bone conduction earphone is inserted into the external auditory canal, the pad portion is deformed and exerts a snug action. The flange portion 1b is also composed of a deformable elastic member. Of course, the cylindrical portion 1a and the spacer 2 can also be formed integrally.
在圓筒部1a或凸緣部1b內部的中空部設有轉換器(電-機轉換器)、即作為本發明主要構件的開孔式骨傳導裝置3。A converter (electro-mechanical converter), that is, an open-hole bone conduction device 3 which is a main component of the present invention, is provided in a hollow portion inside the cylindrical portion 1a or the flange portion 1b.
骨傳導裝置3具有磁性體、緩衝物7、線圈架4以及線圈8，磁性體由動件6和環狀之磁鐵5構成，動件6能夠振動且由磁性材料構成，具有長尺狀之圓筒主體和磁鐵支承部6b，該圓筒主體呈圓筒狀，外周部形成至少一個以上的槽6a，而磁鐵支承部6b一體形成於前述圓筒主體的一端部且直徑比主體圓筒部大，其內部形成收納空間，環狀之磁鐵5收納於前述動件6的磁鐵支承部6b內，緩衝物7由設於組成前述磁性體的動件6的槽6a中之橡膠一類的彈性構件所構成，線圈架4在內周面上設有容納緩衝物用的槽，並隔著緩衝物7與主體圓筒部相離開而形成非接觸狀態，在形成於前述線圈架4的兩端的凸緣4a之間捲繞有線圈8。另外，磁鐵支承部6b不一定要做成圖示的筒狀，也可以做成圓板狀或其它適宜的形狀。The bone conduction device 3 has a magnetic body, a buffer 7, a bobbin 4, and a coil 8. The magnetic body is composed of a movable member 6 and a ring-shaped magnet 5. The movable member 6 can vibrate and is made of a magnetic material, and has a long-shaped circle. a cylindrical body and a magnet supporting portion 6b having a cylindrical shape, at least one or more grooves 6a are formed in an outer peripheral portion, and the magnet supporting portion 6b is integrally formed at one end portion of the cylindrical body and has a larger diameter than the main cylindrical portion The storage space is formed inside, and the ring-shaped magnet 5 is housed in the magnet support portion 6b of the movable member 6, and the cushion member 7 is made of an elastic member such as rubber provided in the groove 6a of the movable member 6 constituting the magnetic body. In the configuration, the bobbin 4 is provided with a groove for accommodating the buffer on the inner peripheral surface, and is separated from the main body cylindrical portion via the cushion 7 to form a non-contact state, and flanges formed at both ends of the bobbin 4 are formed. A coil 8 is wound between 4a. Further, the magnet supporting portion 6b does not have to be formed in a cylindrical shape as shown, and may have a disk shape or another suitable shape.
該等動件6的主體圓筒部、緩衝物7位於線圈架4的中空狀主體部的空間內。The main body cylindrical portion and the cushion 7 of the movable member 6 are located in the space of the hollow main body portion of the bobbin 4.
在以上結構中，磁鐵5用粘接劑或填縫等固定方法設置於動件6的磁鐵支承部6b內。並且，磁鐵5的中央部的開孔5a與動件6的主體圓筒部內的孔呈同軸狀而相互連通，另外，與在殼體1的圓筒部1a的內端部側(插入外耳道時位於鼓膜側的部分)的中央部形成的孔1a’也呈同軸狀並相互連通。In the above configuration, the magnet 5 is provided in the magnet supporting portion 6b of the movable member 6 by a fixing method such as an adhesive or a caulking. Further, the opening 5a in the central portion of the magnet 5 and the hole in the main body cylindrical portion of the movable member 6 are coaxially communicated with each other, and on the inner end portion side of the cylindrical portion 1a of the casing 1 (when the external auditory canal is inserted) The holes 1a' formed in the central portion of the portion located on the tympanic membrane side are also coaxial and communicate with each other.
磁鐵5設於在凸緣1b內形成的空間a內，磁鐵支承部6b與凸緣部1b的內面之間形成非接觸狀態，從而不會妨礙動件6的振動。另外，緩衝物7的內周面側位於動件6的槽6a中，緩衝物7的外周面側則位於線圈架4的捲繞部的內周面側，在線圈架4與動件6的主體圓筒部之間設有間隙，以便於動件6振動。該動件6最好採用高導磁率的材質。The magnet 5 is provided in the space a formed in the flange 1b, and the magnet support portion 6b and the inner surface of the flange portion 1b are in a non-contact state, so that the vibration of the movable member 6 is not hindered. Further, the inner peripheral surface side of the cushioning member 7 is located in the groove 6a of the movable member 6, and the outer peripheral surface side of the cushioning member 7 is located on the inner peripheral surface side of the wound portion of the bobbin 4, and the bobbin 4 and the movable member 6 are A gap is provided between the cylindrical portions of the main body to facilitate the vibration of the movable member 6. The moving member 6 is preferably made of a material having a high magnetic permeability.
又，在圖中所示的實施例中，譬如由鐵或不銹鋼一類之磁性材料所構成的動件6與磁鐵5是分開的結構，但也可以採用將譬如六方晶鐵氧磁體磁性粉末、燒結用不銹鋼粉末一類之合金粉末等成形為一體的磁性體。Further, in the embodiment shown in the drawings, for example, the movable member 6 composed of a magnetic material such as iron or stainless steel is separated from the magnet 5, but a magnetic powder such as a hexagonal ferrite magnet may be used, and sintering may be employed. A magnetic body formed into an integral alloy powder such as stainless steel powder.
另外，在第1圖中，符號1c表示在凸緣部1b的外側形成的開孔部。In addition, in Fig. 1, reference numeral 1c denotes an opening portion formed on the outer side of the flange portion 1b.
第2圖是表示開孔式骨傳導裝置3的組裝示例的說明圖。Fig. 2 is an explanatory view showing an example of assembly of the open-hole bone conduction device 3.
在組裝過程中，如下側的圖所示，將磁鐵5置於呈細長略為圓筒狀的動件6之磁鐵支承部6b。為了便於理解磁鐵5的安裝狀態，圖示之例是以剖面來表示磁鐵支承部6b的部分。另外，如圖中中間部分所示，在譬如一對槽6a中安裝緩衝物7，宜將橫向分割型之二分割結構的一對線圈架半體4’分別相對向配置，且從兩側將緩衝物7的外周部收納在內部，宜藉由超音波焊接將線圈架半體4’的接合部焊接成一體，且如圖中最上部所示般形成線圈架4。如上述般使線圈架4為橫向分割的二分割結構，藉此使之為易於在內部收納緩衝物7等的構造，並為組裝性優異者。另外，圖中所示的線圈架4是左右橫向分割的結構，但也可以是上下一分為二的縱向分割結構。還有，磁鐵5也可以在最後製程裝入，也可以在任意階段裝入。又，磁鐵支承部6也可不為前述之筒狀，也可以做成圓板狀或其它形狀。In the assembly process, as shown in the following figure, the magnet 5 is placed in the magnet support portion 6b of the movable member 6 which is elongated and slightly cylindrical. In order to facilitate understanding of the mounting state of the magnet 5, the illustrated example shows a portion of the magnet support portion 6b in a cross section. Further, as shown in the middle portion of the figure, in the case where the buffer 7 is attached to, for example, a pair of grooves 6a, it is preferable to arrange the pair of bobbin halves 4' of the two-division structure of the laterally split type, respectively, from opposite sides. The outer peripheral portion of the cushion 7 is housed inside, and it is preferable to weld the joint portion of the bobbin half 4' integrally by ultrasonic welding, and the bobbin 4 is formed as shown in the uppermost portion of the drawing. As described above, the bobbin 4 has a two-divided structure in which the bobbin 4 is divided into the horizontal direction, thereby making it easy to accommodate the cushion 7 and the like inside, and is excellent in assemblability. Further, the bobbin 4 shown in the drawing is a structure in which the right and left sides are divided horizontally, but it may be a vertically divided structure in which the upper and lower sides are divided into two. Further, the magnet 5 may be loaded in the final process or may be loaded at any stage. Further, the magnet supporting portion 6 may not be in the above-described cylindrical shape, and may be formed in a disk shape or another shape.
如第3圖所示，在線圈架4的主體部的外周捲繞線圈8，即完成如第1(a)圖所示的開孔式骨傳導裝置3。在第3圖中，8a、8b是聲音信號通電用的線圈8的引出線。As shown in Fig. 3, the coil 8 is wound around the outer circumference of the main body portion of the bobbin 4, that is, the open-hole bone conduction device 3 as shown in Fig. 1(a) is completed. In Fig. 3, 8a and 8b are lead lines of the coil 8 for energizing the sound signal.
如第1(a)圖所示，該骨傳導裝置3透過插入法或裝填法而設置於殼體1的中空部內。此時，磁鐵5位於外側(殼體1的凸緣部1b內)。所謂插入法，如其字面所示，就是插入殼體1的中央部後宜使用粘接劑進行固定的方法。裝填法亦然。As shown in Fig. 1(a), the bone conduction device 3 is placed in the hollow portion of the casing 1 by an insertion method or a filling method. At this time, the magnet 5 is located outside (in the flange portion 1b of the casing 1). The insertion method, as shown in the figure, is a method of fixing by using an adhesive after inserting into the central portion of the casing 1. The same applies to the filling method.
第4圖是從側面看組裝完畢的開孔式骨傳導耳機3A的說明圖。凸緣部1b的外周面與襯墊2的外周部之間有極小的高低差、或是沒有高低差，使用時，凸緣部1b的部分也會被插入外耳道。但是，採用該骨傳導耳機時，當將插入耳朵部分、即襯墊2部分插入外耳道時，由於磁鐵的中央部的孔、動件6的通氣孔6’或殼體1的孔1a’等的存在，外耳道不會被堵塞。Fig. 4 is an explanatory view of the assembled open-hole bone conduction earphone 3A as seen from the side. There is an extremely small difference in height between the outer peripheral surface of the flange portion 1b and the outer peripheral portion of the spacer 2, or there is no height difference. When used, the portion of the flange portion 1b is also inserted into the external auditory canal. However, when the bone conduction earphone is used, when the insertion ear portion, that is, the pad 2 portion is inserted into the external auditory canal, the hole in the central portion of the magnet, the vent hole 6' of the movable member 6, or the hole 1a' of the housing 1 or the like Exist, the external auditory canal will not be blocked.
使用時，如第5圖所示，將開孔式骨傳導耳機3A整個地插入外耳道A中。並且經過引出線8a、8b(見第3圖，第5圖中為了便於圖示而未示出)而將聲音電流通向開孔式骨傳導裝置的線圈8。第5圖表示了外耳A’、中耳B’、內耳C’等的結構。另外，D’表示鼓膜、E’表示耳咽管，F’表示耳蝸，G’表示槌骨a、砧骨b、鐙骨c等聽小骨。In use, as shown in Fig. 5, the open-hole bone conduction earphone 3A is entirely inserted into the external auditory canal A. Further, the sound current is supplied to the coil 8 of the open-hole bone conduction device via the lead wires 8a, 8b (see Fig. 3, which is not shown for convenience of illustration in Fig. 5). Fig. 5 shows the structure of the outer ear A', the middle ear B', the inner ear C' and the like. Further, D' indicates the tympanic membrane, E' indicates the eustachian tube, F' indicates the cochlea, and G' indicates the ossicles such as the tibia a, the anvil b, and the tibia c.
第6(a)、6(b)圖～第9(a)、9(b)圖表示骨傳導裝置3的振動原理。第6(a)、6(b)圖是流到線圈8的電流和由此發生的磁場Φa、Φb的說明圖。第7圖表示磁性體之一例，第8(a)、8(b)圖是已發生的磁場所產生的F作用於磁性體的說明圖，第9(a)、9(b)圖表示發生的磁場Φa、Φb與磁鐵的磁場Φm間的關係。Figures 6(a) and 6(b) to 9(a) and 9(b) show the principle of vibration of the bone conduction device 3. 6(a) and 6(b) are explanatory diagrams of the current flowing to the coil 8 and the magnetic fields Φa and Φb generated thereby. Fig. 7 shows an example of a magnetic body, and Figs. 8(a) and 8(b) are explanatory diagrams of F generated by a generated magnetic field acting on a magnetic body, and Figs. 9(a) and 9(b) are diagrams showing occurrence. The relationship between the magnetic fields Φa, Φb and the magnetic field Φm of the magnet.
即，在第6(a)、(b)圖中，一旦交流的聲音電流經過引出線8a、8b流到線圈8，根據安培的右螺旋定律，使發生的磁通Φa、Φb的方向如箭頭所示般沿著電流ia、ib的方向交替變化。所謂安培的右螺旋定律，是表示電流與其周圍產生的磁場之間關係的定律，是指當電流流通，將電流的方向作為右螺旋的前進方向，沿著右螺旋的螺旋方向產生磁場。圖中4是線圈架，6是裝置，7是緩衝物。本例的動件6如圖所示，是在一端部設有磁鐵5之構造的磁性體。That is, in the sixth (a) and (b) diagrams, once the alternating sound current flows through the lead lines 8a, 8b to the coil 8, the direction of the generated magnetic fluxes Φa, Φb is as indicated by the right spiral law of the amperage. As shown, it alternates along the direction of the currents ia, ib. The right-spiral law of ampere is a law that expresses the relationship between a current and a magnetic field generated around it. It means that when a current flows, the direction of the current is taken as the direction of advance of the right helix, and a magnetic field is generated along the spiral direction of the right helix. In the figure, 4 is a bobbin, 6 is a device, and 7 is a cushion. The movable member 6 of this example is a magnetic body having a structure in which a magnet 5 is provided at one end as shown in the drawing.
當在線圈8的中心配置如第7圖所示的在一端部具有磁鐵5的高導磁率材料的動件6，就會受到根據弗萊明的左手定則產生的力F。如第8(a)、(b)圖所示，該力F作用於對動件6予以支撐的方向，而該動件6係藉由緩衝物7隔著間隙而配置在線圈架4的中空部。箭頭表示由電流ia、ib的方向而產生的F的方向。When the movable member 6 having the high magnetic permeability material having the magnet 5 at one end as shown in Fig. 7 is disposed at the center of the coil 8, the force F generated according to Fleming's left-hand rule is received. As shown in Figs. 8(a) and 8(b), the force F acts on the direction in which the movable member 6 is supported, and the movable member 6 is disposed in the hollow of the bobbin 4 by the buffer 7 via the gap. unit. The arrows indicate the direction of F produced by the directions of the currents ia, ib.
如第9(a)、(b)圖所示，保持用緩衝物7機械性支撐著由磁鐵5與動件6一體形成的磁性體，因此聲音信號使Φa和Φb影響磁鐵5的磁通Φm而導致磁性體的上下運動。該振動傳遞到線圈架4，進而通過覆蓋振動體自身的構件而傳遞到骨頭並傳遞到聽覺神經。此時，重要的是覆蓋振動體的構件要與外耳道的硬度類似，且可與裝填周邊緊貼。至於保持用緩衝物7，如果能取得動件6的平衡，則用1個亦可。另外，為了使動件6能夠迅速地振動，緩衝物7以硬度較低者為佳。As shown in Figs. 9(a) and (b), the holding buffer 7 mechanically supports the magnetic body integrally formed by the magnet 5 and the movable member 6, so that the sound signal causes Φa and Φb to affect the magnetic flux Φm of the magnet 5. This causes the magnetic body to move up and down. This vibration is transmitted to the bobbin 4, and is transmitted to the bone by the member covering the vibrating body itself and transmitted to the auditory nerve. At this time, it is important that the member covering the vibrating body is similar in hardness to the external auditory canal and can be closely attached to the filling periphery. As for the holding buffer 7, if the balance of the movable member 6 can be obtained, one may be used. Further, in order to allow the movable member 6 to vibrate rapidly, the cushioning member 7 preferably has a lower hardness.
由磁鐵5、動件6、緩衝物7、線圈架4和線圈8等所構成的作為振動體發揮作用的骨傳導裝置3係設置在殼體1內，而振動會傳遞到殼體1。The bone conduction device 3 that functions as a vibrating body composed of the magnet 5, the movable member 6, the cushioning member 7, the bobbin 4, and the coil 8 is provided in the casing 1, and vibration is transmitted to the casing 1.
一般的空氣音是聲音在空氣中作為振動而傳播且使鼓膜振動，並傳遞到被稱為耳蝸的聽覺器官。相對於此，本發明的骨傳導裝置3的振動是在第5圖中從耳小骨G’直接傳遞給耳蝸F’之後的聽覺神經，作為聲音而被大腦識別。The general air sound is that the sound propagates as vibration in the air and vibrates the tympanic membrane and transmits it to the auditory organ called the cochlea. On the other hand, the vibration of the bone conduction device 3 of the present invention is the auditory nerve which is directly transmitted from the auricle G' to the cochlea F' in Fig. 5, and is recognized by the brain as a sound.
第10圖是本發明的第2實施例的剖視圖。本實施例的特徵在於將整體的外形做成軸向稍長的大致圓筒狀。第11(a)圖是表示外觀之說明圖，第11(b)圖是正面圖。Figure 10 is a cross-sectional view showing a second embodiment of the present invention. The present embodiment is characterized in that the overall outer shape is formed into a substantially cylindrical shape slightly longer in the axial direction. Fig. 11(a) is an explanatory view showing the appearance, and Fig. 11(b) is a front view.
本實施例中，動件6的形狀較為簡單。即，其特徵在於將動件6做成細長的圓筒狀，在其一端部(插入外耳道後相當於外耳道的外側位置)的外周上裝有環狀的磁鐵5，構成開孔式骨傳導裝置3。在本例中，動件6的一端部作為磁鐵5的支承部而發揮作用。In this embodiment, the shape of the movable member 6 is relatively simple. That is, the moving member 6 is formed into an elongated cylindrical shape, and an annular magnet 5 is mounted on the outer circumference of one end portion (the outer position corresponding to the external auditory canal after insertion into the external auditory canal) to constitute an open-hole bone conduction device. 3. In this example, one end portion of the movable member 6 functions as a support portion of the magnet 5.
第12圖表示骨傳導裝置3的其它實施例。在該第3實施例中，在動件6的端部安裝有磁鐵5，使緩衝物7和槽6a為一，且動件6或線圈架4的軸方向尺寸較短，除此之外，基本結構與前述的骨傳導裝置3大致相同，故省略說明。Fig. 12 shows another embodiment of the bone conduction device 3. In the third embodiment, the magnet 5 is attached to the end of the movable member 6, so that the cushion 7 and the groove 6a are one, and the axial direction of the movable member 6 or the bobbin 4 is short, and Since the basic structure is substantially the same as that of the above-described bone conduction device 3, description thereof will be omitted.

Fig. 16(a) is a side view of the appearance thereof, and Fig. 16(b) is a front view.
本實施例的特徵在於將骨傳導耳機做成耳栓式，用由具防水性之彈性部件構成的罩子1d來覆蓋要插入外耳道的骨傳導裝置3，而能夠在水中使用。此時，磁鐵5的外周與防水罩子1d的內面之間存在間隙，以免妨礙振動。The present embodiment is characterized in that the bone conduction earphone is made into an earplug type, and the bone conduction device 3 to be inserted into the external auditory canal is covered with a cover 1d made of a waterproof elastic member, and can be used in water. At this time, there is a gap between the outer circumference of the magnet 5 and the inner surface of the waterproof cover 1d so as not to interfere with the vibration.
在本實施例中，緩衝物7為一個，當然也可如第1圖所示之實施例般採用有兩個緩衝物7的骨傳導裝置。In the present embodiment, the buffer 7 is one. Of course, a bone conduction device having two cushions 7 can be used as in the embodiment shown in Fig. 1.
另外，罩子1d的形狀當然也不限於圖中所示的例子。又，也可不用罩子1d，而是在骨傳導裝置3的中央部軸方向之通氣孔6’內安裝可自由脫卸的可防止水進入內部之防水性蓋狀栓(圖中未示)，當插入大致呈圓柱狀或有底圓筒狀之栓時，就可在水中使用，而當除下栓時，通氣孔6’便與大氣連通並可在陸地上使用，由此成為水陸兩用式。In addition, the shape of the cover 1d is of course not limited to the example shown in the drawing. Further, instead of the cover 1d, a waterproof cap-shaped plug (not shown) that can be detached and prevented from entering the inside can be attached to the vent hole 6' in the axial direction of the central portion of the bone conduction device 3, when When inserting a plug having a substantially cylindrical shape or a bottomed cylindrical shape, it can be used in water, and when the plug is removed, the vent hole 6' is connected to the atmosphere and can be used on land, thereby becoming an amphibious type. .
