Description
本發明乃是關於一種可調音的耳機。 The invention relates to a headphone with adjustable sound.
現今人們為了聽音樂時不干擾到周圍的人，而常佩戴耳機聽音樂，且因耳機係為人們常隨身攜帶的物品，因此攜帶式耳機應訴求體積小且輕巧。 Nowadays, in order to listen to music, people often wear headphones to listen to music, and because headphones are articles that people often carry with them, portable headphones should appeal to small size and light weight.
然而傳統的耳機殼體多為密閉空間，以致發音時受限於殼內部密封空間既定的大小，而影響到其輸出聲音屬性。又因耳機的體積小而導致共鳴空間較小，故無法提供較好的低音效果。又，因人們使用耳機的時機很多，例如：聽音樂、聊天及玩遊戲...等等，然而不同時機所提供的聲音不同，其對耳機的參數要求變會不同，然而傳統耳機令使用者自行改變耳機參數。 However, the conventional earphone housing is mostly a closed space, so that the sound is limited by the predetermined size of the sealed space inside the shell, and its output sound property is affected. Because the volume of the earphone is small, the resonance space is small, so it cannot provide a good bass effect.

The tuning cover 20 is rotatably disposed at an end of the venting cover 10 away from the user's ear, and the elastic member 50 is disposed at an end of the audible unit 30 near the user's ear 9. . When the tuning earphone 1 is worn on the user's ear 9, a front chamber is formed between the elastic member 50, the sounding unit 30 and the user's ear 9.
發聲單體30可依照成本、頻率、靈敏度需求、音質及使用壽命...等因素選擇動圈式、靜電式和平衡電樞式等不同驅動方式。彈性件50係為高密度海綿耳墊、矽膠耳塞、或為海綿耳塞。使用時，彈性件50的一端貼合於使用者耳朵，以增加具有調音耳機1於使用者耳朵的密閉性及舒適性。彈性件50的選擇，係以其放置位置而選擇。如彈性件50放置於使用者耳道，意即調音耳機1為入耳式耳機，彈性件50選擇耳塞形式。如本實施例的彈性件50係抵於使用者的耳廓，意即調音耳機1為罩耳式耳機(參圖7所示)，彈性件50則選擇耳墊形式。 The sounding unit 30 can select different driving modes such as moving coil type, electrostatic type and balanced armature type according to factors such as cost, frequency, sensitivity demand, sound quality and service life. The elastic member 50 is a high density sponge ear pad, a silicone earplug, or a sponge earplug. In use, one end of the elastic member 50 is attached to the user's ear to increase the airtightness and comfort of the tuning earphone 1 to the user's ear. The selection of the elastic member 50 is selected in accordance with its placement position. For example, the elastic member 50 is placed on the ear canal of the user, that is, the tuning earphone 1 is an in-ear earphone, and the elastic member 50 is selected in the form of an earplug. The elastic member 50 of the present embodiment is in contact with the auricle of the user, that is, the tuning earphone 1 is an earphone (refer to FIG. 7), and the elastic member 50 is in the form of an ear pad.
參圖1、圖2及圖3所示，透氣蓋10包括一環部11、一透氣平面12及一限位壁13，透氣平面12設有至少一透氣孔121，於本發明實施例中透氣孔121的數量為6個，透氣孔121的數量不在此限。透氣平面12設置於環部11遠離使用者耳朵9的一端，令環部11遠離使用者耳朵9的一端大致封閉。環部11的內側面為一曲面111，且曲面111係朝環部11圓心方向彎曲，此種結構配置令氣流可順暢地經過曲面111，且氣體應曲面111而被壓縮，使得聲音頻率產生變化。限位壁13係由透氣平面12朝遠離使用者耳朵9的方向延伸形成，限位壁13與透氣平面12共同形成一開口朝遠離使用者耳朵9方向的容置空間131。環部11、透氣平面12及限位壁13係一體成型。 As shown in FIG. 1 , FIG. 2 and FIG. 3 , the venting cover 10 includes a ring portion 11 , a gas permeable surface 12 and a limiting wall 13 . The gas permeable surface 12 is provided with at least one venting opening 121 , which is a venting hole in the embodiment of the present invention. The number of 121 is six, and the number of the vent holes 121 is not limited thereto. The venting surface 12 is disposed at an end of the ring portion 11 away from the user's ear 9, such that the end of the ring portion 11 away from the user's ear 9 is substantially closed. The inner side surface of the ring portion 11 is a curved surface 111, and the curved surface 111 is curved toward the center of the ring portion 11. This structural arrangement allows the airflow to smoothly pass through the curved surface 111, and the gas is compressed by the curved surface 111, so that the sound frequency changes. . The limiting wall 13 is formed by extending the venting surface 12 away from the user's ear 9. The limiting wall 13 and the venting surface 12 together form an accommodating space 131 opening away from the user's ear 9. The ring portion 11, the gas permeable surface 12 and the limit wall 13 are integrally formed.
調音蓋20包括一環部21及一調音平面22，調音平面22設有至少一個調音孔221，調音孔221的截面積及數量與透氣孔121相同。調音平面22設置於調音蓋20環部21靠近使用者耳朵9的一端，環部21遠離使用者耳朵9的一端朝外徑向延伸形成一握持部211。調音蓋20的環部21、調音平面22及握持部211係一體成型。 The tuning cover 20 includes a ring portion 21 and a tuning plane 22, and the tuning plane 22 is provided with at least one tuning hole 221, and the cross-sectional area and number of the tuning hole 221 are the same as those of the venting hole 121. The tuning plane 22 is disposed at one end of the ring portion 21 of the tuning cover 20 near the user's ear 9, and the end portion of the ring portion 21 away from the user's ear 9 extends radially outward to form a grip portion 211. The ring portion 21, the tuning plane 22, and the grip portion 211 of the tuning cover 20 are integrally formed.
以下為透氣蓋10、調音蓋20及發聲單體30的組合細部說明，發聲單體30設置於透氣蓋10環部11靠近使用者耳朵9的一端， 使得透氣蓋10與發聲單體30共同形成一後腔室14。調音蓋20的調音平面22與透氣蓋10的透氣平面12貼平，調音蓋20環部21的外徑大致等於透氣蓋10限位壁的內徑，使得環部21及調音平面22可恰好地放置於容置空間131。握持部211抵於限位壁13遠離使用者耳朵9的一端，且握持部211的外徑大於限位壁13的外徑，方便使用者直接或間接的藉由握持部211轉動調音蓋20。換句話說，使用者直接用手指握持調音蓋20的握持部211轉動，亦可利用裝飾蓋(圖未示)及齒輪(圖未示)的配置轉動握持部211。 The following is a detailed description of the combination of the venting cover 10, the tuning cover 20 and the sounding unit 30, and the sounding unit 30 is disposed at one end of the ring portion 11 of the venting cover 10 near the user's ear 9. The venting cap 10 and the sounding unit 30 are combined to form a rear chamber 14. The tuning plane 22 of the tuning cover 20 is flush with the venting plane 12 of the venting cover 10, and the outer diameter of the ring portion 21 of the tuning cover 20 is substantially equal to the inner diameter of the limiting wall of the venting cover 10, so that the ring portion 21 and the tuning plane 22 can be exactly It is placed in the accommodating space 131. The grip portion 211 is opposite to the end of the limiting wall 13 away from the user's ear 9 , and the outer diameter of the grip portion 211 is larger than the outer diameter of the limiting wall 13 , so that the user can rotate the tuning directly or indirectly by the grip portion 211 . Cover 20. In other words, the user directly grips the grip portion 211 of the tuning cover 20 with a finger, and the grip portion 211 can be rotated by the arrangement of a decorative cover (not shown) and a gear (not shown).
當發聲單體30欲發出聲音而產生振動時，前腔室51及後腔室14的氣壓產生變化，因前腔室51係由彈性件50、使用者耳朵9共同形成，而使用者耳朵9會應使用者的不同而形狀大小不同，因此前腔室51的大小並無法掌握，且於聲學腔體中，前腔室51係提供高頻共振，如前腔室漏氣或開孔，會使低頻減弱。而後腔室14係由透氣蓋10定義，因此後腔室14的體積大致固定，而後腔室14係提供低頻共振，然而完全密閉的後腔室14對發聲單體30的阻尼較大，利用透氣孔121連通外界與後腔室14內的空氣，令後腔室14對發聲單體30的阻尼較小。 When the sounding unit 30 is to emit a sound to generate vibration, the air pressures of the front chamber 51 and the rear chamber 14 are changed, because the front chamber 51 is formed by the elastic member 50 and the user's ear 9, and the user's ear 9 Depending on the user, the shape and size are different, so the size of the front chamber 51 cannot be grasped, and in the acoustic cavity, the front chamber 51 provides high-frequency resonance, such as a leak or opening of the front chamber. Reduce the low frequency. The rear chamber 14 is defined by the venting cover 10, so that the volume of the rear chamber 14 is substantially fixed, while the rear chamber 14 provides low frequency resonance, whereas the fully enclosed rear chamber 14 dampens the audible unit 30, utilizing ventilation. The hole 121 communicates with the outside air and the air in the rear chamber 14, so that the rear chamber 14 is less damped to the sounding unit 30.
參圖4、圖5及圖6所示，調音蓋20可相對透氣蓋10轉動，令使用者可調整透氣孔121與調音孔221的連通截面積。如圖4所示，透氣孔121皆被調音平面22所封閉，意即調音孔221與透氣孔121完全不連通，其效果於後敘述。如圖5所示，透氣孔121有部分被調音平面22所封閉，調音孔221與透氣孔121部分連通。如圖6所示，調音孔221與透氣孔121完全連通。 As shown in FIG. 4, FIG. 5 and FIG. 6, the tuning cover 20 is rotatable relative to the venting cover 10, so that the user can adjust the communication cross-sectional area of the venting hole 121 and the tuning hole 221. As shown in FIG. 4, the venting holes 121 are all closed by the tuning plane 22, that is, the tuning hole 221 and the venting opening 121 are completely disconnected, and the effect thereof will be described later. As shown in FIG. 5, the vent hole 121 is partially closed by the tuning plane 22, and the tuning hole 221 is partially in communication with the vent hole 121. As shown in FIG. 6, the tuning hole 221 is completely in communication with the vent hole 121.
利用調音蓋20可調整透氣孔121與調音孔221的連通截面積，令使用者可調整後腔室14對發聲單體30的阻尼大小及最低共振頻率fo，藉此改變調音耳機1的阻抗曲線。 The tuning cover 20 can adjust the communication cross-sectional area of the vent hole 121 and the tuning hole 221, so that the user can adjust the damping of the sounding unit 30 and the lowest resonance frequency f o of the rear chamber 14 , thereby changing the impedance of the tuning earphone 1 . curve.
以下先說明耳機的最低共振頻率fo及品質因素Q值(或稱諧振點)，fo代表喇叭阻抗曲線第一個極大值對應的頻率，當聲音頻率 於fo值附近時，其振動較強，因此頻率於fo值附近聲音的表現效果較佳。Q值的代表意義為發聲單體30的抑振能力，換而言之Q值可反應發聲單體30的阻尼狀態。當Q值過低時，發聲單體30輸出聲壓還沒到便迅速下降，發聲單體30處於阻尼狀態，造成低頻衰減過大。當Q值過高時，發聲單體30係屬欠阻尼狀態，低頻過分加強。就聽覺而言，Q值偏低時，所發出的低音短而不脫尾，換言之聲音無法延續，而Q值偏高時，所發出的低音下潛較深，然而聲音較緊。因此fo、Q值應依照使用者的喜好及播放聲音類型調整。使用者可依照調音耳機1的應用時機(例如：聊天、玩遊戲及聽音樂)對fo、Q值需求不同，進而調整本發明調音耳機1，以達到最好的聲音效果。關於各種模式的特性敘述如後。 The following describes the minimum resonance frequency f o and the quality factor Q value (or resonance point) of the earphone. f o represents the frequency corresponding to the first maximum value of the horn impedance curve. When the sound frequency is near the f o value, the vibration is better. Strong, so the sound is better at the frequency around the f o value. The representative value of the Q value is the vibration suppression capability of the sounding unit 30, in other words, the Q value can reflect the damping state of the sounding unit 30. When the Q value is too low, the sound pressure of the sounding unit 30 is rapidly decreased after the sound pressure is not reached, and the sounding unit 30 is in a damping state, causing the low frequency attenuation to be excessive. When the Q value is too high, the sounding unit 30 is in an underdamped state, and the low frequency is excessively strengthened. As far as hearing is concerned, when the Q value is low, the sound is short and not tailed. In other words, the sound cannot be continued, and when the Q value is high, the bass is deeper, but the sound is tight. Therefore, the f o and Q values should be adjusted according to the user's preference and the type of playback sound. The user can adjust the f o and Q values according to the application timing of the tuning earphone 1 (for example, chatting, playing games, and listening to music), thereby adjusting the tuning earphone 1 of the present invention to achieve the best sound effect. The characteristics of the various modes are described later.
圖8為調音耳機1於不同狀態下的阻抗曲線實驗圖，S1為發聲單體30於自由空間下的阻抗曲線，S2-S7為發聲單體30於透氣蓋10中的阻抗曲線，S2係為調音孔221與透氣孔121完全不連通的狀態，S3係為調音孔221與透氣孔121連通孔數為1個的狀態，S4係為調音孔221與透氣孔121的連通孔數為2個的狀態，S5係為調音孔221與透氣孔121的連通孔數為3個的狀態，S6係為調音孔221與透氣孔121的連通孔數為4個的狀態，S7係為調音孔221與透氣孔121的連通孔數為5個的狀態。又Q值的公式如下：
fo為最低共振頻率，RE為頻率高於最低共振頻率(fo)時的最低阻抗值，ZO為最低共振頻率(fo)時的阻抗值，f2-f1為阻抗值為R1時的兩頻率相減，即為帶寬。以圖8的S3曲線為例，最高峰A點所對應的頻率為fo(圖上標示為fos3)，最高峰A點所對應的阻抗值 為ZO(圖上標示為ZOS3)，曲線最低B點所對應的阻抗值為RE(圖上標示為RES3)，因此可求出R1數值，藉以找出f2-f1(帶寬)數值。 f o is the lowest resonance frequency, R E is the lowest impedance value when the frequency is higher than the lowest resonance frequency (f o ), Z O is the impedance value at the lowest resonance frequency (f o ), and f 2 -f 1 is the impedance value The two frequencies at R 1 are subtracted, which is the bandwidth. Taking the S 3 curve of Fig. 8 as an example, the frequency corresponding to the highest peak A is f o (labeled as f os3 ), and the impedance corresponding to the highest peak A is Z O (labeled as Z OS3 ) The impedance value corresponding to the lowest point B of the curve is R E (labeled as R ES 3), so the value of R 1 can be obtained to find the value of f 2 -f 1 (bandwidth).
由圖8及品質因素Q的公式可見，當發聲單體30裝設於透氣蓋10及調音蓋20後，其fo、Q值皆改變，且隨著調音孔221與透氣孔121的連通孔數不同，fo、Q值亦會改變。大體而言，當fo值降低，Q值亦會降低。 It can be seen from the formula of FIG. 8 and the quality factor Q that when the sounding unit 30 is mounted on the venting cover 10 and the tuning cover 20, the f o and Q values thereof change, and the connecting holes of the tuning hole 221 and the vent hole 121 are provided. The number of f o and Q will also change. In general, when the value of f o decreases, the Q value also decreases.
由上述可知，於每一透氣孔121及調音孔221的連通狀態不同時，Q值及fo值會有所改變。因此本發明調音耳機1的透氣蓋10及調音蓋20的設置，可令使用者選擇所欲Q值及fo值，以達到最佳的聲音效果。 As can be seen from the above, when the communication state of each of the vent hole 121 and the tuning hole 221 is different, the Q value and the f o value are changed. Therefore, the ventilation cover 10 and the tuning cover 20 of the tuning earphone 1 of the present invention allow the user to select the desired Q value and the f o value to achieve the best sound effect.
於本發明另一實施例，調音耳機1更包括一被動音膜40，被動音膜40係為彈性材質製成。被動音膜40封閉調音蓋20遠離使用者耳朵9的一端，且被動音膜40設有一中心凸起部41及一環形凸起部42，環形凸起部42環設於中心凸起部41，環形凸起部42及中心凸起部41皆朝遠離使用者耳朵9的方向凸出。被動音膜40上還設有一重量配置盤43。利用環形凸起部42及中心凸起部41的設置，使得被動音膜40更具有彈性，而重量配置盤43可改變被動音膜40的整體重量。 In another embodiment of the present invention, the tuning earphone 1 further includes a passive sound film 40, and the passive sound film 40 is made of an elastic material. The passive sound film 40 closes one end of the tuning cover 20 away from the user's ear 9 , and the passive sound film 40 is provided with a central convex portion 41 and an annular convex portion 42 . The annular convex portion 42 is annularly disposed on the central convex portion 41 . Both the annular projection 42 and the central projection 41 project in a direction away from the user's ear 9. A weight distribution plate 43 is also disposed on the passive sound film 40. With the arrangement of the annular raised portion 42 and the central raised portion 41, the passive sound film 40 is made more elastic, and the weight disposition plate 43 can change the overall weight of the passive sound film 40.
利用被動音膜40封閉調音蓋20遠離使用者耳朵9的一端，使得調音蓋20與被動音膜40形成一調音腔室23。因被動音膜40為可彈性的材質，使得調音腔室23的容積大小可稍微改變。當透氣孔121與調音孔221連通時，後腔室14與調音腔室23相連通，利用調音腔室23的容積大小可改變，令後腔室14對發聲單體30的阻尼較小。因此被動音膜40不但可使後腔室14對發聲單體30的阻尼改變，更使得後腔室14與調音腔室23仍保有密閉式耳機聲音乾淨的特性，令外界聲音不易干擾。 The passive sound film 40 is used to close one end of the tuning cover 20 away from the user's ear 9, so that the tuning cover 20 and the passive sound film 40 form a tuning chamber 23. Since the passive sound film 40 is an elastic material, the volume of the tuning chamber 23 can be slightly changed. When the vent hole 121 communicates with the tuning hole 221, the rear chamber 14 communicates with the tuning chamber 23, and the volume of the tuning chamber 23 can be changed, so that the damping of the sounding unit 30 by the rear chamber 14 is small. Therefore, the passive sound film 40 not only changes the damping of the sounding unit 30 of the rear chamber 14, but also allows the rear chamber 14 and the tuning chamber 23 to maintain the clean sound of the closed earphone, so that the external sound is not easily interfered.
圖9為調音蓋20裝設有被動音膜40且調音耳機1於不同狀態下的阻抗曲線圖。於圖9中，S1’為發聲單體30於自由空間下 的阻抗曲線，S2’-S6’為發聲單體30於透氣蓋10中且調音蓋20設有被動音膜40的阻抗曲線，S2’係為調音孔221與透氣孔121完全不連通的狀態，S3’係為調音孔221與透氣孔121連通孔數為1個的狀態，S4’係為調音孔221與透氣孔121的連通孔數為2個的狀態，S5’係為調音孔221與透氣孔121的連通孔數為3個的狀態，S6’係為調音孔221與透氣孔121的連通孔數為4個的狀態。由圖9可見，發聲單體30與透氣蓋10、調音蓋20及被動音膜40結合後，其阻抗曲線S2’-S6’的fo及Q值會改變。 FIG. 9 is a graph showing the impedance of the tuning cover 20 with the passive sound film 40 and the tuning earphone 1 in different states. In FIG. 9, S1' is an impedance curve of the sounding unit 30 in free space, S2'-S6' is a sounding unit 30 in the gas permeable cover 10, and the tuning cover 20 is provided with a passive sound film 40 impedance curve, S2 ' is a state in which the tuning hole 221 and the vent hole 121 are completely disconnected, S3' is a state in which the number of communicating holes of the tuning hole 221 and the vent hole 121 is one, and S4' is a communicating hole of the tuning hole 221 and the vent hole 121. In the state of two, S5' is a state in which the number of communication holes of the tuning hole 221 and the vent hole 121 is three, and S6' is a state in which the number of communication holes of the tuning hole 221 and the vent hole 121 is four. As can be seen from Fig. 9, after the sounding unit 30 is combined with the gas permeable cover 10, the tuning cover 20 and the passive sound film 40, the f o and Q values of the impedance curves S2'-S6' are changed.
於本發明另一實施例，調音耳機1更包括一調音紙60，調音紙60係由半透氣材質製成。調音紙60封閉調音孔221的一端，使得氣流通過透氣孔121進一步通過調音孔221時，會通過調音紙60，並進一步改變後腔室14對發聲單體30阻尼狀態，使得調音耳機1的fo、Q值改變。 In another embodiment of the present invention, the tuning earphone 1 further includes a tuning paper 60, and the tuning paper 60 is made of a semi-breathable material. The tuning paper 60 closes one end of the tuning hole 221, so that when the airflow passes through the vent hole 121 and further passes through the tuning hole 221, it passes through the tuning paper 60, and further changes the damping state of the sounding unit 30 of the rear chamber 14 so that the tuning earphone 1 is f o , Q value changes.
在此簡單敘述前述各種模式的參數狀態，因人類於說話時所發出的聲音頻率大約為500-6000Hz，因此調音耳機1於調音孔221與透氣孔121連通孔數為0時的fo、Q值為較佳的聊天模式。而遊戲音效的聲音頻率多較低，且音效短促即時，因此調音耳機1於調音孔221與透氣孔121連通孔數為1時的fo、Q值為較佳的遊戲模式。音樂的聲音頻率偏低，其聲音須延續，因此調音耳機1於調音孔221與透氣孔121連通孔數為5時的fo、Q值為較佳的聽音樂模式。以上對於連通孔數的描述係參考透氣蓋10、調音蓋20、發聲單體30及被動音膜40的規格、材質而定，故不以此為限。 Here, the parameter states of the above various modes are briefly described. The frequency of the sound emitted by the human being when speaking is about 500-6000 Hz, so the tuning earphone 1 is connected to the vent hole 221 and the vent hole 121 when the number of holes is 0, f o , Q The value is the preferred chat mode. The sound frequency of the game sound effect is low, and the sound effect is short and instantaneous. Therefore, the f o and Q values of the tuning earphone 1 when the number of the communication holes 221 and the vent hole 121 are 1 are better game modes. The sound frequency of the music is low, and the sound thereof has to be continued. Therefore, the f o and Q values of the tuning earphone 1 when the number of the communication holes 221 and the vent hole 121 are 5 are better listening music modes. The description of the number of the communication holes is based on the specifications and materials of the ventilating cover 10, the tuning cover 20, the sounding unit 30, and the passive sound film 40, and is not limited thereto.
參圖1及圖7，於本發明實施例，調音耳機1包括一殼體60，透氣蓋10、調音蓋20及發聲單體30容置於殼體60內，發聲單體30外露於殼體60，使發聲單體30朝使用者耳朵9發出聲音，彈性件50設置於殼體60靠近使用者耳朵9的一端，使調音耳機1呈罩耳式耳機結構。 1 and 7, in the embodiment of the present invention, the tuning earphone 1 includes a casing 60. The venting cover 10, the tuning cover 20 and the sounding unit 30 are housed in the casing 60, and the sounding unit 30 is exposed to the casing. 60, the sounding unit 30 is made to sound toward the user's ear 9, and the elastic member 50 is disposed at one end of the casing 60 near the user's ear 9, so that the tuning earphone 1 is in the earphone structure.
是以，本發明調音耳機1的特點在於，利用透氣蓋10與調音蓋20分別設有孔數相對應的透氣孔121及調音孔221，且調音蓋20係可轉動地設置於透氣蓋10，令使用者可調整後腔室14對發聲單體30的Q值大小，讓使用者可選擇適合的調音耳機1模式。 Therefore, the tunable earphone 1 of the present invention is characterized in that the venting cover 10 and the tuning cover 20 are respectively provided with venting holes 121 and tuning holes 221 corresponding to the number of holes, and the tuning cover 20 is rotatably disposed on the venting cover 10, The user can adjust the Q value of the sounding unit 30 of the rear chamber 14 to allow the user to select a suitable tuning headphone 1 mode.
