Description

Technical Field

[0001] This invention relates to a type of headphone, and more particularly to an open-back headphone. Background Technology

[0002] Generally speaking, in-ear headphones seal the user's ear canal, preventing music from being disturbed by external sounds. However, this can also easily cause discomfort such as blockage or closure. To avoid these discomforts, some users choose non-in-ear headphones.

[0003] For example, non-in-ear headphones rely solely on ear hooks for positioning, making them prone to slipping or shifting during vigorous exercise. This displacement can cause misalignment of the sound outlet and the radial direction of sound output, preventing the full frequency range of music from being properly directed into the ear canal. This results in distorted sound quality or unstable sound due to movement. Furthermore, the ear hooks of non-in-ear headphones are typically suspended from the upper part of the earlobe, creating a smaller contact area between the user's skin and the headphone, which can lead to feelings of insecurity as the headphones may fall out or be lost. Summary of the Invention

[0004] This invention relates to an open-back headphone that offers high positioning stability and good sound quality reception stability when worn by the user.

[0005] The open-back headphones of the present invention include a housing, a speaker, a connector, and a support. The housing has an internal accommodating space and a sound outlet on its surface. The speaker is disposed within the accommodating space, dividing the space into a front cavity and a rear cavity. The sound outlet of the housing is acoustically connected to the front cavity. The connector includes a first end and a second end in a opposed state, the first end of the connector being connected to the surface of the housing. The support is connected to the second end of the connector and includes a bearing portion and a sound outlet channel. When a user wears the open-back headphones, the housing is located in the concha of the user's ear, the bearing portion of the support abuts against at least the lower edge of the user's concha, and the sound outlet of the housing and the sound outlet channel of the support are acoustically connected to the user's ear canal. The sound outlet of the housing does not contact the user's ear. The lower edge of the concha is defined as the area below an imaginary line extending horizontally from the center of the opening of the user's ear canal.

[0006] In one embodiment of the present invention, the aforementioned support portion has a first side opposite to the housing. When the user wears open-back headphones, the first side of the support portion corresponds to the user's ear canal opening and does not completely block the ear canal opening through the sound outlet channel.

[0007] In one embodiment of the present invention, the aforementioned support portion has a second side facing the housing, the support portion surrounds the sound outlet channel, and the sound outlet channel penetrates the first side and the second side of the support portion.

[0008] In one embodiment of the present invention, the sound output from the speaker passes sequentially through the sound outlet provided in the housing, the second side of the support portion, the first side of the support portion, and the ear canal opening.

[0009] In one embodiment of the present invention, the opening width of the first side of the bearing portion is equal to the opening width of the second side of the bearing portion.

[0010] In one embodiment of the present invention, the opening width of the first side of the bearing portion is smaller than the opening width of the second side of the bearing portion.

[0011] In one embodiment of the invention, an auxiliary positioning member is further included, which is connected to the housing and is used to clamp onto a portion of the user's ear.

[0012] In one embodiment of the present invention, when the user wears open-back headphones, the auxiliary positioning member and the user's auricle contact surface generate a force in a first direction, and the support member and the shell together contact the user's concha cavity to generate a force in a second direction, the first direction being opposite to the second direction.

[0013] In one embodiment of the present invention, the aforementioned support portion is a closed ring.

[0014] In one embodiment of the present invention, the aforementioned support portion is a non-closed ring shape.

[0015] In one embodiment of the present invention, the supporting member has a first supporting edge and a second supporting edge, the first supporting edge abutting against the upper edge of the concha cavity, and the second supporting edge abutting against the lower edge of the concha cavity.

[0016] In one embodiment of the present invention, the orthogonal axis at the center of the imaginary line connecting the first and second bearing edges of the bearing portion is defined as a first axial direction, which is parallel to the sound output direction of the sound outlet channel. The orthogonal axis at the center of the imaginary line connecting the first and second inner edges of the sound outlet hole is defined as a second axial direction. The first axial direction of the bearing portion is parallel to the second axial direction of the sound outlet hole; or, the included angle between the first axial direction of the bearing portion and the second axial direction of the sound outlet hole is between 0° and 45°.

[0017] In one embodiment of the present invention, the sound outlet and the sound channel are positioned opposite to the user's ear canal, and there is no obstruction between the sound outlet and the sound channel.

[0018] Based on the above, in the open-back headphones of the present invention, the housing is located in the concha cavity of the user's ear, and the supporting part of the support abuts against at least the lower edge of the user's concha cavity to maintain the relative position of the sound outlet and the ear canal, so that the headphone music can pass through the sound outlet channel of the support according to a specific path and be smoothly transmitted to the user's ear canal.

[0074] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element symbols are used in the drawings and description to denote the same or similar parts.

[0075] Figure 1 This is a perspective view of an open-back headphone according to an embodiment of the present invention. Figure 2 yes Figure 1 A side view diagram of an open-back headphone. Please refer to... Figure 1 and Figure 2 The open-back earphone 100 of this embodiment includes a housing 110, a connector 130, and a support 140. It should be noted that, in reality, there is a pair of earphones, but since the components of the left and right earphones are actually the same, the following description will use the right earphone as an example.

[0076] Figure 3 yes Figure 1 A cross-sectional diagram of an open-back headphone. Please refer to... Figure 3 In this embodiment, the connector 130 is located between the housing 110 and the support member 140. The connector 130 includes a first end 131 and a second end 132 in a relative position. The first end 131 of the connector 130 is connected to the surface of the housing 110. The support member 140 is connected to the second end 132 of the connector 130. In this embodiment, the support member 140 is fixed to the housing 110 through the connector 130. However, in other embodiments, the support member and the housing can be connected by other suitable structures or methods, and the present invention is not limited thereto.

[0077] In detail, in this embodiment, the housing 110 has an accommodating space 111 inside, and a sound outlet 113 is formed on the surface of the housing 110. The open-back headphone 100 also includes a speaker 120, which is disposed within the accommodating space 111 to define the accommodating space 111 into a front cavity F1 and a rear cavity R1. The sound generated by the speaker 120 can be discharged through the sound outlet 113 provided in the housing 110. The sound outlet 113 provided in the housing 110 is acoustically connected to the front cavity F1.

[0078] Figure 4A This is a diagram of the user's ear. Figure 4B yes Figure 1 A diagram illustrating the wearing characteristics of open-back headphones. Please refer to it first. Figure 4A In this embodiment, the ear 10 of the user 20 has structures such as a concha 11, an ear canal 12, a helix 13, an antihelix 14, a crus of the helix 15, a tragus 16, an antitragus 17, and an earlobe 18. In this embodiment, the lower edge 11b of the concha 11 is defined as the region A1 below an imaginary line extending horizontally in a direction L1 from the center position C1 of the opening of the ear canal 12 of the user 20. Please refer to... Figure 4B In this embodiment, when the user 20 wears the open-back headphones 100, the housing 110 is located in the concha 11 of the user 20's ear 10. Here, the housing 110 has an egg-shaped appearance, and the lower end 112 of the housing 110 is arc-shaped, which is used to clamp or support and fix it with the lower edge 11b of the user 20's outer ear concha 11, thereby enhancing the stability of the housing 110 conforming to the user 20's ear 10. The present invention is not limited thereto.

[0079] In this embodiment, the support member 140 includes a bearing portion 142 and a sound outlet channel 144. The bearing portion 142 of the support member 140 at least abuts against the lower edge 11b of the user's concha cavity, but the present invention is not limited thereto.

[0080] In this embodiment, the sound outlet 113 of the housing 110 and the sound outlet channel 144 of the support 140 are acoustically connected to the ear canal 12 of the user 20, but the sound outlet 113 of the housing 110 does not contact the ear 10 of the user 20. The sound outlet channel 144 contains air, and the sound generated by the speaker 120 is conducted as musical sound through the air as a medium. The bearing portion 142 of the support 140 provides a positioning function and separates the sound outlet 113 from the ear 10 of the user 20, so that the sound outlet 113 does not directly contact the ear 10 of the user 20.

[0081] Under the above configuration, the open-back headphones 100 of this embodiment utilize the housing 110 located in the concha cavity 11, and the supporting portion 142 of the support member 140 at least abuts against the lower edge 11b of the concha cavity 11 to maintain the relative position of the sound outlet 113 provided by the housing 110 and the ear canal 12, so that the music of the open-back headphones 100 can pass through the sound outlet channel 144 of the support member 140 according to a specific path and be smoothly transmitted to the ear canal 12 of the user 20, so that the positioning stability is high when the user 20 wears the open-back headphones 100 and has good sound quality reception stability.

[0082] For more details, please refer to Figure 2 In this embodiment, the support portion 142 of the support member 140 is a closed annular shape. For example, the support portion 142 is circular to form a sound outlet channel 144. In other embodiments, the support portion may also have other suitable shapes to correspond to the concha of the user's ear, and the present invention is not limited thereto.

[0083] In this embodiment, the bearing portion 142 of the support member 140 has a first bearing edge 1421 and a second bearing edge 1422. Please refer to... Figure 4B The first bearing edge 1421 abuts against the upper edge 11a of the concha cavity 11, and the second bearing edge 1422 abuts against the lower edge 11b of the concha cavity 11. Since the support member 140 mainly rests in the concha cavity 11, it can limit and ensure that the center position C1 of the sound outlet hole 113 provided in the housing 110 and the opening of the ear canal 12 is maintained, so that the sound output by the speaker 120 can be transmitted axially along a specific path M1 and pass through the sound outlet channel 144 of the support member 140, and be smoothly transmitted into the ear canal 12.

[0084] In this embodiment, the support portion 142 has a first side S1 facing away from the housing 110. Specifically, when the user 20 wears the open-back headphones 100, the first side S1 of the support portion 142 corresponds to the opening of the user 20's ear canal 12, and does not completely block the opening of the ear canal 12 through the sound outlet channel 144. The support portion 142 has a second side S2 facing the housing 110, and the support portion 142 surrounds the sound outlet channel 144, which passes through the first side S1 and the second side S2 of the support portion 142. In this embodiment, the sound output by the speaker 120 comes from the sound outlet 113 provided in the housing 110, passes sequentially through the second side S2 of the support portion 142, the sound outlet channel 144, and the first side S1 of the support portion 142, and reaches the ear canal 12.

[0085] In this embodiment, the sound outlet 113 and the sound outlet channel 144 are positioned opposite to the ear canal 12 of the user 20, and there is no obstruction between the sound outlet 113 and the sound outlet channel 144. The obstruction may be a baffle, mesh, or other component, and the present invention is not limited thereto.

[0086] In this embodiment, the opening width D1 of the first side S1 of the bearing portion 142 is equal to the opening width D2 of the second side S2 of the bearing portion 142, but the present invention is not limited thereto.

[0087] To elaborate further, please refer to Figure 1 and Figure 4B The open-back headphones 100 further include an auxiliary positioning member 160, which is connected to the housing 110 and is used to clip onto a portion of the user's ear 10. The auxiliary positioning member 160 is, for example, an earhook. In this embodiment, the auxiliary positioning member 160 is adapted to rest against the connection between the user's ear 10 and head, but this is not a limitation of the invention. In one embodiment, the auxiliary positioning member 160 is made of a resilient material, but this is not a limitation of the invention.

[0088] Please refer to Figure 4B In this embodiment, when the user 20 wears the open-back headphones 100, the auxiliary positioning member 160 and the contact surface of the user 20's auricle generate a force in a first direction N1, and the support member 140 and the housing 110 together contact the user 20's concha 11, generating a force in a second direction N2. The first direction N1 is opposite to the second direction N2, thus forming a bidirectional force relationship. In addition, because the contact area between the user 20's skin and the open-back headphones 100 is increased, the user can feel a sense of security.

[0089] In this embodiment, the axial direction of the bearing portion 142 is parallel to the axial direction of the sound outlet 113. Specifically, as shown... Figure 3 In the cross-sectional view shown, in this embodiment, the orthogonal axis of the center position C2 on the imaginary line connecting the first bearing edge 1421 and the second bearing edge 1422 of the bearing portion 142 is defined as a first axial direction X1, which is parallel to the sound output direction of the sound output channel 144. Figure 3 In the cross-sectional view shown, in this embodiment, the orthogonal axis of the center position C3 on the imaginary line connecting the first inner edge 113a and the second inner edge 113b of the sound outlet 113 is defined as a second axial direction X2, which is parallel to the sound outlet direction of the sound outlet channel 144. In this embodiment, the first axial direction X1 of the supporting part 142 is parallel to the second axial direction X2 of the sound outlet 113, that is, the included angle between the first axial direction X1 and the second axial direction X2 is 0° or between 0° and 45°, and the present invention is not limited thereto.

[0090] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals representing the same or similar components, and descriptions of identical technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

[0091] Figure 5 This is a front cross-sectional view of a user wearing open-back headphones according to another embodiment of the present invention. Please refer to... Figure 5 In this embodiment, the open-back headphone 100B and Figure 4B The open-back headphone 100 differs slightly, primarily in that the opening width D3 of the first side S3 of the support portion 142B is smaller than the opening width D4 of the second side S4 of the support portion 142B. In other words, the inner diameter of the sound outlet channel 144B of the support member 140B decreases from the innermost part closer to the housing 110 towards the distal end. However, this invention is not limited to this. In other embodiments, the acoustic characteristics of sound passing through the support member can be altered by changing the cross-sectional design of the support portion, the material of the parts, the surface treatment, or other suitable methods, increasing the possibilities for tuning. This invention does not limit this to such modifications.

[0092] Figure 6 This is a top cross-sectional view of a user wearing open-back headphones according to another embodiment of the present invention. Please refer to... Figure 6 In this embodiment, the sound outlet 113C of the housing 110C is located in region A2, which includes region A21 and region A22.

[0093] Figure 6 The open-back headphones are worn on the user's right ear. In one embodiment, the sound outlet 113C is located in region A21. The support portion 142C defines inner edges E1 and E2. A tangent through the inner edge E1 of the support portion 142C is defined as a third axis X3, which is parallel to the first axis X1. A tangent through the inner edge E2 of the support portion 142C is defined as a fourth axis X4, which is parallel to the first axis X1. Region A21 is the area between the third axis X3 and the fourth axis X4 corresponding to the housing 110C; alternatively, the sound outlet 113C may also be located in region A22, which is the area of ​​the housing 110C corresponding to the third axis X3 rotated 60 degrees clockwise around the intersection of the imaginary line connecting the inner edges E1 and E2 with the inner edge E1. The sound outlet 113C is adapted to be positioned within region A2 so that the sound transmission path can enter the ear canal 12 at an optimal ergonomic angle when passing through the center position C2 of the support member 140. In other embodiments, as long as the sound from the speaker can pass directly from the sound outlet provided in the housing through the support member to the ear canal, it is within the scope of protection of this invention.

[0094] Figures 7A to 7C This is a schematic diagram of an open-back headphone according to another embodiment of the present invention. Please refer to [the diagram first]. Figure 7A In this embodiment, the open-back headphone 100D and Figure 2 The open-back headphones 100 are slightly different, mainly in the shape of the support part 142D. The support part 142D of the open-back headphones 100D is a non-closed ring, specifically, the support part 142D is a semi-closed ring.

[0095] Please refer to Figure 7B In this embodiment, the support portion 142E of the open-back headphone 100E is a closed irregular shape.

[0096] Please refer to Figure 7C In this embodiment, the support portion 142F of the open-back headphone 100F is a semi-closed irregular shape.

[0097] In addition, Figure 1 , Figure 5 , Figure 6 , Figures 7A to 7C In the above embodiments, additional perforations or partial hollowing may be added to the support portion. The present invention does not limit this, as long as it is suitable for the user to wear and the sound outlet of the shell can be acoustically connected to the user's ear canal, it is within the scope of protection of the present invention.

[0098] In summary, in the open-back headphones of this invention, the shell is located within the concha of the user's ear, and the supporting portion of the support rests against at least the lower edge of the user's concha to maintain the relative position of the sound outlet and the ear canal. This allows the headphone music to travel along a specific path through the sound outlet channel of the support and be smoothly transmitted to the user's ear canal, precisely maintaining the specific relative relationship between the sound outlet and the concha, thus preventing uncomfortable wearing sensations such as blockage or closure. Furthermore, the auxiliary positioning member generates a clamping force in a specific direction with the auricle contact surface. This, combined with the supporting surface of the support within the concha and the lower end of the shell against the supporting surface at the lower edge of the concha of the outer ear, generates a clamping force in the opposite direction. The coexistence of these three forces forms a bidirectional force relationship, achieving high positioning stability and good sound quality reception stability when the user wears the headphones.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
