Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a speaker assembly, headrest, seat and vehicle. Background Technology

[0002] Existing single speakers often struggle to produce high-quality sound across the entire low-mid or low-mid-high frequency range. To address this issue, current technologies typically employ several speakers with different frequency ranges working together to expand the frequency range. However, this approach suffers from significant sound leakage when multiple speakers are in operation, negatively impacting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a speaker assembly, headrest, seat, and vehicle that can expand the sound range while avoiding sound leakage.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Speaker components, including:

[0006] First loudspeaker;

[0007] The second loudspeaker has a lower frequency range than the first loudspeaker, and the sound-emitting axes of the first loudspeaker and the second loudspeaker intersect at the sound-receiving point.

[0008] Preferably, at least two second speakers are provided, all of which are arranged circumferentially around the first speaker.

[0009] Preferably, all the second speakers are evenly distributed around the circumference of the first speaker or symmetrically arranged with respect to the first speaker.

[0010] The headrest includes a headrest body and the aforementioned speaker assembly, wherein the speaker assembly is mounted on the headrest body.

[0011] Preferably, two speaker components are provided, the headrest body is provided with a support surface, and the two speaker components are spaced apart on the support surface along a first direction.

[0012] Preferably, the support surface is provided with a head positioning part, and the two speaker components are symmetrically arranged with respect to the head positioning part.

[0013] Preferably, the headrest body is provided with a neck support portion, which is located on one side of the headrest body in a second direction, the second direction being perpendicular to the first direction.

[0014] Preferably, the headrest body is provided with a sound insulation part, the sound insulation part and the support surface form a sound receiving space, and the speaker assembly is located in the sound receiving space.

[0015] Preferably, there are two sound insulation sections, which are spaced apart along the first direction, forming the sound receiving space between them, and the two speaker components are located between the two sound insulation sections.

[0016] Preferably, the sound insulation part extends along the second direction and is elongated, with the second direction being perpendicular to the first direction.

[0017] Seats, including the aforementioned speaker components or headrests.

[0018] Vehicles, including the aforementioned speaker components, headrests, or seats.

[0019] The beneficial effects of this utility model are:

[0020] The first speaker has a lower frequency range than the second speaker. When the first and second speakers work together, they can effectively expand the overall frequency range. Furthermore, the sound axes of the first and second speakers intersect at the sound reception point, which corresponds to the human ear during use. This focuses the sound on the human ear, creating a reinforced area. The sound intensity in the reinforced area is much higher than that in areas outside the reinforced area, ensuring loudness at the human ear while reducing loudness in areas outside the reinforced area, thus achieving the purpose of preventing sound leakage.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-5 As shown, this utility model provides a speaker assembly, including a first speaker 1 and a second speaker 2. The sound range of the first speaker 1 is lower than that of the second speaker 2, and the sound-emitting axes of the first speaker 1 and the second speaker 2 intersect at the sound-receiving point.

[0035] In this embodiment, the sound range of the first speaker 1 is lower than that of the second speaker 2. The first speaker 1 and the second speaker 2 work together to effectively expand the overall sound range. On this basis, the sound-emitting axes of the first speaker 1 and the second speaker 2 intersect at the sound-receiving point. When in use, the sound-receiving point corresponds to the human ear, thereby focusing the sound on the human ear and forming a reinforced area at the human ear. This makes the sound intensity in the reinforced area much higher than the sound intensity in the area outside the reinforced area, ensuring the loudness at the human ear while reducing the loudness in the area outside the reinforced area, thus achieving the purpose of preventing sound leakage.

[0036] Specifically, at least two second speakers 2 are provided, and all second speakers 2 are arranged circumferentially around the first speaker 1. This arrangement further ensures the sound output effect.

[0037] More specifically, all the second speakers 2 are evenly distributed around the circumference of the first speaker 1 or symmetrically arranged with respect to the first speaker 1. This arrangement further ensures the sound output effect.

[0038] More specifically, there are eight second speakers 2, which are evenly distributed around the first speaker 1.

[0039] More specifically, the first speaker 1 is a woofer, and the second speaker 2 is a mid-high frequency speaker. This arrangement ensures the integrity of the sound and achieves a balance across the high, mid, and low frequencies.

[0040] The frequency range refers to the range of frequencies between the lowest and highest frequencies that a loudspeaker can achieve. In this embodiment, such as... Figure 2 and Figure 4 As shown by the dotted line, the sound axis of the first speaker 1 and all the second speakers 2 is the axis of its upper diaphragm. The bass speaker's frequency range is usually no greater than 200Hz. When it produces sound, it is deep and impactful, providing a basic sense of rhythm and impact to the music. The mid-high frequency speaker's frequency range covers the mid-to-high frequency range, 500Hz–5kHz, connecting the bass and treble frequencies. It is mainly responsible for the core timbre of mid-to-high frequency instruments such as vocals and strings, ensuring a natural and smooth sound.

[0041] In other embodiments, the second speaker 2 may be configured in other quantities such as 4, 5, or 6, depending on the requirements.

[0042] In other embodiments, the second speaker 2 may also be a tweeter with a frequency range typically not less than 2kHz, producing a bright and clear tone that can reproduce delicate details and a sense of space.

[0043] In other embodiments, the second speaker 2 may also be a mid-range speaker with a frequency range covering 200Hz-2000Hz.

[0044] In other embodiments, the plurality of second speakers 2 may also include at least two of a midrange speaker, a mid-high frequency speaker, and a tweeter.

[0045] The woofer, midrange speaker, mid-high frequency speaker and tweeter are conventional devices in this field, and their specific structures and working principles are conventional and will not be described in detail here.

[0046] This embodiment also provides a headrest, including a headrest body 100 and the aforementioned speaker assembly. The headrest body 100 is used to support the user's head, and the speaker assembly is installed on the headrest body 100.

[0047] In the headrest of this embodiment, the sound range of the first speaker 1 is lower than that of the second speaker 2. The first speaker 1 and the second speaker 2 work together to effectively expand the overall sound range. On this basis, the sound-emitting axes of the first speaker 1 and the second speaker 2 intersect at the sound-receiving point. When in use, the sound-receiving point corresponds to the human ear, thereby focusing the sound on the human ear and forming a reinforced area at the human ear. This makes the sound intensity in the reinforced area much higher than the sound intensity in the area outside the reinforced area, ensuring the loudness at the human ear while reducing the loudness in the area outside the reinforced area, thus achieving the purpose of preventing sound leakage.

[0048] Specifically, two speaker components are provided. The headrest body 100 is provided with a support surface 101, and the two speaker components are spaced apart on the support surface 101 along a first direction. The above arrangement makes it easier to assemble the speaker components on the headrest body 100, occupies less space, and allows the two speaker components to directly act on the user's two ears when the user's head is placed on the support surface 101.

[0049] More specifically, the support surface 101 is provided with a head positioning part 102, and the two speaker components are symmetrically arranged with respect to the head positioning part 102. The head positioning part 102 is used to place the user's head and achieve head positioning, so that the two speaker components and the user's two ears are precisely aligned.

[0050] In this embodiment, the support surface 101 is a plane, the speaker assembly is arranged in a plane, and the head positioning part 102 is a groove recessed relative to the support surface 101. The bottom of the groove of the head positioning part 102 is an arc-shaped surface or a spherical surface, so that the user's head is more comfortable when it is against the support surface.

[0051] In other embodiments, the support surface 101 may also be an arc surface, and the head positioning part 102 may also be a groove formed by a protruding structure protruding from the support surface 101.

[0052] In other embodiments, the speaker assembly may also be installed inside the headrest body 100, or set independently relative to the headrest body 100.

[0053] Specifically, the headrest body 100 is provided with a neck support portion 103, which is located on one side of the headrest body 100 in a second direction, perpendicular to the first direction. The neck support portion 103 is used to support the user's neck and ensure the position of the user's ears in the second direction.

[0054] More specifically, the neck support 103 extends along the first direction and is elongated. This design makes the support for the user's neck more stable and reliable.

[0055] In this embodiment, the neck support 103 is a single protrusion that protrudes from the support surface 101, with a semi-circular cross-section, making it more comfortable for the user's neck to rest against.

[0056] In other embodiments, the neck support 103 may also be a plurality of protrusions protruding relative to the support surface 101, and the plurality of protrusions are arranged in a row along the first direction.

[0057] Preferably, the head positioning part 102 and the neck support part 103 cooperate to ensure the position of the user's ears in the first and second directions, so that the left and right ears can accurately correspond one-to-one with the two speaker components, such as... Figure 2 As shown by the dashed line, the sound-emitting axes of the first speaker 1 and all the second speakers 2 of one speaker assembly intersect at the user's left ear, while the sound-emitting axes of the first speaker 1 and all the second speakers 2 of another speaker assembly intersect at the user's right ear.

[0058] In other embodiments, the neck support 103 may also be hemispherical and positioned opposite and spaced apart from the head positioning part 102 in the second direction.

[0059] In other embodiments, the cross-section of the elongated neck support 103 may also be trapezoidal or other shapes.

[0060] Specifically, the headrest body 100 is provided with a sound insulation part 104, which and the support surface 101 form a sound receiving space, and the speaker assembly is located in the sound receiving space. The above arrangement can prevent the sound emitted by the speaker assembly from leaking out.

[0061] More specifically, two sound insulation sections 104 are provided, spaced apart along a first direction, forming a sound-receiving space between them, and two speaker components are located between the two sound insulation sections 104. This arrangement simplifies the sound insulation section 104 and efficiently achieves sound insulation.

[0062] More specifically, the sound insulation part 104 extends along the second direction and is elongated. This arrangement further ensures the blocking effect on the sound output of the speaker assembly.

[0063] In this embodiment, the sound insulation part 104 and the sound-speaking component are arranged facing each other in the first direction, forming a single protrusion protruding from the support surface 101. In the second direction, the size of the sound insulation part 104 is not smaller than the size of the sound-speaking component, thereby ensuring the obstruction of the sound output of the sound-speaking component.

[0064] In other embodiments, the sound insulation part 104 may also be a plurality of protrusions protruding relative to the support surface 101, and the plurality of protrusions are arranged in a row along the second direction.

[0065] In other embodiments, two sound insulation parts 104 are provided, each sound insulation part 104 is arc-shaped and is arranged around the side of its corresponding speaker assembly away from the other speaker assembly.

[0066] In other embodiments, a sound insulation section 104 may also be provided, which is U-shaped in shape and extends from the top of the two speaker components to the opposite sides of the two speaker components. The inner side of the U-shaped structure of the sound insulation section 104 forms a sound receiving space, and the two speaker components are located in the sound receiving space.

[0067] This embodiment also provides a seat, including the aforementioned speaker assembly or headrest.

[0068] In the seat of this embodiment, the sound range of the first speaker 1 is lower than that of the second speaker 2. The first speaker 1 and the second speaker 2 work together to effectively expand the overall sound range. On this basis, the sound-emitting axes of the first speaker 1 and the second speaker 2 intersect at the sound-receiving point. When in use, the sound-receiving point corresponds to the human ear, thereby focusing the sound on the human ear and forming a reinforced area at the human ear. This makes the sound intensity in the reinforced area much higher than the sound intensity in the area outside the reinforced area, ensuring the loudness at the human ear while reducing the loudness in the area outside the reinforced area, thus achieving the purpose of preventing sound leakage.

[0069] This embodiment also provides a vehicle, including the aforementioned speaker assembly, headrest, or seat.

[0070] In the vehicle of this embodiment, the sound range of the first speaker 1 is lower than that of the second speaker 2. The first speaker 1 and the second speaker 2 work together to effectively expand the overall sound range. On this basis, the sound-emitting axes of the first speaker 1 and the second speaker 2 intersect at the sound-receiving point. When in use, the sound-receiving point corresponds to the human ear, thereby focusing the sound on the human ear and forming a reinforced area at the human ear. This makes the sound intensity in the reinforced area much higher than the sound intensity in the area outside the reinforced area, ensuring the loudness at the human ear while reducing the loudness in the area outside the reinforced area, thus achieving the purpose of preventing sound leakage.
