Description

Technical Field

[0001] This application relates to the field of headphones. Background Technology

[0002] Modern headphones include open-back headphones. The characteristic of open-back headphones is that they do not completely cover or block the entrance to the ear canal, maintaining a larger distance between the headphone's sound outlet and the ear canal. This larger gap allows the user to hear external sounds. Due to the structure of open-back headphones, the distance between the sound outlet and the ear canal varies depending on the ear shape, resulting in inconsistent audio experiences for each user. Furthermore, the larger distance between the sound outlet and the ear canal causes greater signal attenuation as it enters the ear canal, leading to a decrease in the overall audio performance of open-back headphones. Summary of the Invention

[0003] Therefore, it is necessary to provide a type of headphone that addresses the issues of unstable fit and poor audio experience.

[0004] According to this application, an earphone is provided, suitable for wearing in one ear, the earphone comprising:

Figure 3 yes Figure 1 A diagram of headphones. Figure 4 yes Figure 3 A schematic diagram of the headphones from another perspective. Figure 5 yes Figure 3 A cross-sectional view of the headphones. Figure 6 yes Figure 3 An exploded view of the headphones. Please also refer to... Figures 1 to 6 The earphone 100 can be worn in one ear 200. The earphone 100 includes an acoustic component 110 and a wearing component 120. The wearing component 120 is connected to the acoustic component 110. The acoustic component 110 and the wearing component 120 together form an acoustic chamber P. The wearing component 120 includes a positioning part 121, a sound outlet surface 122, and an acoustic sound outlet 123. The acoustic sound outlet 123 is located on the sound outlet surface 122 and communicates with the acoustic chamber P. The earphone 100 of this embodiment is, for example, an open-back wireless earphone, but is not limited thereto. Multiple acoustic components and multiple electronic components (not shown) may be disposed within the acoustic chamber P.

[0068] When the earphone 100 is worn in the ear 200, the positioning part 121 extends into the ear 200 and abuts against the concha 210 of the ear 200, while the sound-emitting surface 122 faces the ear canal 220 of the ear 200. Because the earphone 100's wearing part 120 extends into the concha 210 of the ear 200, the sound-emitting surface 122 of the wearing part 120 is closer to the ear canal entrance 221 of the ear canal 220, and the acoustic sound outlet 123 on the sound-emitting surface 122 is closer to the ear canal entrance 221. The earphone 100, through the positioning part 121, connects more stably to ears 200 of different ear shapes and shortens the distance between the sound-emitting surface 122 (acoustic sound outlet 123) and the ear canal 220, thereby reducing the attenuation of signal energy transmitted from the earphone 100 into the ear canal 220 and improving the audio experience and performance of the earphone 100.

[0069] The headphone 100 of this embodiment also includes an ambient sound channel 130. The ambient sound channel 130 is disposed on the wearing member 120, but is not limited thereto. The ambient sound channel 130 includes a channel body 131, an ambient sound outlet 132, and an ambient sound inlet 133. The ambient sound outlet 132 and at least a portion of the ambient sound inlet 133 are connected to the channel body 131, and the ambient sound outlet 132 is located on the sound outlet surface 122. External sounds (i.e., ambient sounds) enter the channel body 131 through the ambient sound inlet 133 and enter the ear 200 through the ambient sound outlet 132. Therefore, the headphone 100 can transmit ambient sounds to the ear canal 220 through the ambient sound channel 130 while covering most of the concha 210. This allows for a more stable ratio of audio frequency and ambient sound emitted from the acoustic outlet 123, without being affected by the ear shape of the ear 200. In an embodiment not shown, the ambient sound channel 130 may be a path of a specific size formed between the earphone 100 and the ear 200 when the earphone 100 is worn on the ear 200, or a channel formed in other ways.

[0070] like Figures 2 to 5 As shown, the wearing device 120 includes an inlet surface 124. An extension line L1 of the acoustic component 110 differs from an extension line L2 of the wearing device 120, causing the acoustic component 110 to be obliquely connected to the inlet surface 124 of the wearing device 120, but this is not a limitation. The ambient sound channel 130 includes an ambient sound inlet hole 133. At least a portion of the ambient sound inlet hole 133 communicates with the channel body 131 and is located on the inlet surface 124. In this embodiment, the inlet surface 124 is opposite to the outlet surface 122, the inlet surface 124 being the top surface of the wearing device 120, and the outlet surface 122 being the bottom surface of the wearing device 120, but this is not a limitation. When the earphone 100 is worn on the ear 200, the inlet surface 124 faces the external environment, and the outlet surface 122 faces the ear canal entrance 221.

[0071] In this embodiment, when the earphone 100 is worn on the ear 200, the gap between the wearing member 120 and the concha 210 is smaller than the area of ​​a cross-section A1 of the channel body 131 of the ambient sound channel 130 (i.e., the cross-sectional area of ​​the channel body 131), to ensure that ambient sound can be transmitted through the ambient sound channel 130. In this embodiment, the channel body 131 is inclinedly disposed on the wearing member 120 in a direction parallel to the extension line L1, but is not limited thereto. In an embodiment not shown, the channel body 131 may be disposed on the wearing member 120 in a direction perpendicular to the extension line L2. That is, the channel body 131 may extend vertically.

[0072] In this embodiment, the shapes of the cross-section A1 of the channel body 131, the ambient sound inlet 133, and the ambient sound outlet 132 are different from each other, but are not limited thereto. The cross-section A1 is trapezoidal, the ambient sound inlet 133 is an isosceles trapezoid, and the ambient sound outlet 132 is rectangular. In an embodiment not shown, the shapes of the cross-section A1, the ambient sound inlet 133, and the ambient sound outlet 132 can be any polygon or circle. The shapes of the cross-section A1, the ambient sound inlet 133, and the ambient sound outlet 132 can be the same.

[0073] The area of ​​the acoustic sound outlet 123 is greater than or equal to the area of ​​the ambient sound outlet 132. The cross-sectional area (area of ​​section A1) of the channel body 131 is less than or equal to the area of ​​the ambient sound inlet 133 and less than or equal to the area of ​​the ambient sound outlet 132, but is not limited thereto. In this embodiment, the area of ​​the acoustic sound outlet 123 is greater than the area of ​​the ambient sound outlet 132, and the cross-sectional area of ​​the channel body 131 is less than the area of ​​the ambient sound inlet 133 and less than the area of ​​the ambient sound outlet 132. A portion of the ambient sound inlet 133 is connected to the channel body 131.

[0074] like Figure 1 , Figure 2 and Figure 5 As shown, since the extension line L1 of the acoustic component 110 is different from the extension line L2 of the wearing component 120, the projection of the acoustic component 110 on the wearing component 120 covers the ambient sound inlet hole 133. When the headphones 100 are worn on the ear 200, the tilted acoustic component 110 can prevent external wind from entering the ambient sound channel 130, so that the headphones 100 can maintain a good audio experience.

[0075] like Figure 6As shown, the wearing device 120 includes a support structure 125 and a wearing body 126 connected together. The earphone 100 is connected to the ear 200 through the support structure 125. The material of the support structure 125 may be an elastic material, but is not limited thereto. The wearing body 126 includes a sound-emitting surface 122, a sound-receiving surface 124, and a connecting surface 127. The connecting surface 127 is connected to the sound-emitting surface 122 and the sound-receiving surface 124, and is located between the sound-emitting surface 122 and the sound-receiving surface 124. The connecting surface 127 is a side surface of the wearing body 126, but is not limited thereto. The connecting surface 127 includes a groove 1271, and the support structure 125 includes a protrusion 1254. The protrusion 1254 engages with the groove 1271, thereby connecting the support structure 125 to the connecting surface 127 of the wearing body 126. The acoustic component 110 is connected to the wearing body 126, and together with the wearing body 126, forms an acoustic chamber P. The ambient sound channel 130 is located in the wear body 126, but is not limited thereto. In an embodiment not shown, the ambient sound channel 130 may be disposed between the wear body 126 and the support structure 125.

[0076] The support structure 125 includes a first portion 1251 and a second portion 1252. A protrusion 1254 is located in the first portion 1251, which is connected to the wearing body 126. A positioning portion 121 is located in the first portion 1251 of the support structure 125. The positioning portion 121 has an arc shape, but is not limited thereto. The second portion 1252 includes two opposing ends E1 and E2. The two ends E1 and E2 are connected to the first portion 1251. A hollow structure G is formed between the second portion 1252 and the first portion 1251. The first portion 1251 and the second portion 1252 are integrally formed, for example, but are not limited thereto.

[0077] like Figure 1 and Figure 2 As shown, when the earphone 100 is worn in the ear 200, the positioning part 121 extends into the concha 210, and the tragus 230 of the ear 200 covers the positioning part 121. The second part 1252 of the support structure 125 abuts against the concha 210, and the earphone 100 is stably connected to the ear 200 through the positioning part 121 and the second part 1252. Because the second part 1252 has a hollow structure G between it and the first part 1251, the second part 1252 can be deformed by the pressure of the concha 210, and the second part 1252 can fit different ear shapes 200. In this way, the earphone 100 can be worn in different ear shapes 200, thereby improving the ease of use of the earphone 100.

[0078] The structure of the positioning part 121 and the second part 1252 is not limited to this embodiment. In an embodiment not shown, the structure of the positioning part 121 may be the same as that of the second part 1252, that is, there may be a hollow structure G between the positioning part 121 and the first part 1251. In an embodiment not shown, the second part 1252 may be arc-shaped and have the same structure as the positioning part 121.

[0079] Conventional headphones, limited by their structure, have a sound inlet located at the ear canal entrance 221 when connected to the ear. Figure 2 The distance between the acoustic sound outlet 123 and the ambient sound outlet 132 and the ear canal entrance 221 is relatively large (e.g., 10 mm), resulting in poor audio performance of the headphones. In this embodiment, the headphone 100, by extending into the concha cavity 210 through the positioning part 121, brings the acoustic sound outlet 123 and the ambient sound outlet 132 closer to the ear canal entrance 221; the distance can be, for example, less than 10 mm. In sound pressure level testing, within the range of 100 Hz to 3000 Hz, the sound pressure level of the headphone 100 of this embodiment is 10 dB higher than that of conventional headphones, indicating that the headphone 100 of this embodiment has superior audio performance.

[0080] Figure 7 This is a schematic diagram of an earphone according to another embodiment provided in this application. Figure 8 yes Figure 7 A schematic diagram of the headphones from another perspective; support structure 125a is omitted here. Please also refer to... Figure 4 , Figure 7 and Figure 8 The earphone 100a in this embodiment is similar to that in the previous embodiment, except that in this embodiment, the sound inlet surface 124a of the wearing body 126a of the wearing member 120a is connected to the sound outlet surface 122a and the connecting surface 127a, and the connecting surface 127a is connected to the acoustic component 110a. The positioning part 121a of the wearing member 120a is located on the wearing body 126a. When the earphone 100a is connected to the ear 200, the support structure 125a is connected to the wearing body 126a and an outer shell 240 of the ear 200. Figure 1 The support structure 125a is, for example, an ear clip, but is not limited thereto.

[0081] The connecting surface 127a of the wearing member 120a is opposite to the sound output surface 122a and is the top surface of the wearing member 120a. The sound input surface 124a is located between the connecting surface 127a and the sound output surface 122a and is the side surface of the wearing member 120a. The channel body 131a of the ambient sound channel 130a extends in a direction parallel to the extension line L2 of the wearing member 120a. That is, the channel body 131a extends horizontally. The shape of the cross-section A2 of the channel body 131a is the same as the shape of the ambient sound inlet hole 133a, but is not limited thereto. The area of ​​the ambient sound inlet hole 133a is equal to the cross-sectional area of ​​the channel body 131a (i.e., the area of ​​the cross-section A2) and is larger than the area of ​​the ambient sound outlet hole 132a. The earphone 100a of this embodiment has the same function as the aforementioned embodiment, and will not be described again here.

[0082] In summary, when the earphones of this application are worn in the ear, the earpiece extends into the ear, with the positioning part of the earpiece abutting against the concha of the ear. The earpiece is stably connected to the ear, thereby improving the audio experience of the earphones. The sound-emitting surface of the earpiece faces one ear canal, and the acoustic sound outlet of the earphone is located on the sound-emitting surface, thereby bringing the acoustic sound outlet closer to the ear canal and improving the audio performance of the earphones.
