[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The following is for reference. Figure 1 The speaker assembly 100 according to the present utility model embodiment can realize the sound and light emission effects of the speaker body 2, meet the user's needs, and reduce the need to set up the light strip 3 in the speaker body 2, thereby avoiding the need for redevelopment of the speaker body 2, reducing development costs and shortening the development cycle.

[0026] like Figure 1 As shown, a speaker assembly 100 according to an embodiment of the present invention includes: a mounting plate 1, a speaker body 2, and a light strip 3.

[0027] Mounting plate 1 is provided with a speaker hole 11; speaker body 2 is fixed relative to mounting plate 1, speaker body 2 is provided with speaker diaphragm 21, speaker diaphragm 21 is distributed relative to speaker hole 11; light strip 3 is installed on the side of mounting plate 1 facing speaker body 2, and light strip 3 is configured to reflect light through speaker diaphragm 21 toward speaker hole 11.

[0028] Specifically, the speaker assembly 100 includes a mounting plate 1, a speaker body 2, and a light strip 3. The speaker body 2 is the core component of the speaker assembly 100. It is an electroacoustic transducer that can convert electrical signals into sound waves. Its function is to restore the stored or transmitted audio signals into human-perceptible sound. The mounting plate 1 is plate-shaped and has a large area to provide space for the speaker hole 11. The speaker hole 11 can be set on the mounting plate 1. The speaker hole 11 is a through hole that allows sound waves and air to pass through, so as to propagate sound waves and optimize acoustic performance, ensuring that the sound is natural, clear and low-distortion. The light strip 3 is a lighting product in which LED lights are soldered onto a strip-shaped flexible circuit board through a special process and emit light after being connected to a power source.

[0029] The speaker body 2 and the mounting plate 1 are fixed relative to each other, so that the speaker body 2 and the mounting plate 1 are fixed respectively, and the speaker body 2 and the mounting plate 1 will not move relative to each other during use. For example, when the speaker assembly 100 is applied to a vehicle, the speaker body 2 and the mounting plate 1 can be installed on the door structure at the same time, so that the speaker body 2 and the mounting plate 1 are fixed relative to the door structure, thereby ensuring that the sound waves emitted by the speaker body 2 can be transmitted from the sound hole 11.

[0030] It should be noted that the speaker assembly 100 of this utility model can be installed on any door structure of the vehicle. For ease of description, the following description will take the installation of the speaker assembly 100 on the door structure located on the left side of the vehicle as an example.

[0031] Furthermore, the speaker body 2 is provided with a speaker diaphragm 21. The speaker diaphragm 21 is the core component in the speaker body 2 that directly drives the air to vibrate and generate sound. When the audio signal passes through the speaker coil, the coil is subjected to the Lorentz force in the magnetic field and generates reciprocating motion. This motion directly drives the speaker diaphragm 21 to vibrate, converting electrical energy into mechanical energy. The vibration of the speaker diaphragm 21 causes changes in the density of the surrounding air molecules, forming sound waves. The sound waves are transmitted through the air to the human ear and are perceived as sound, thereby achieving the sound production effect of the speaker body 2.

[0032] When the speaker diaphragm 21 vibrates, it compresses or thins the air inside the speaker assembly 100, causing a change in air pressure inside the speaker assembly 100. If the air pressure cannot be released, it will form a pressure resistance, which will hinder the free movement of the speaker diaphragm 21 and cause distortion (such as muddy low frequencies and sharp high frequencies). By distributing the speaker diaphragm 21 and the speaker hole 11 opposite each other, the speaker diaphragm 21 and the speaker hole 11 can be set facing each other and separated by a certain distance. This allows the sound waves generated by the speaker diaphragm 21 to propagate outward through the speaker hole 11, thereby enabling the speaker body 2 to emit sound. Furthermore, external air can flow from the side away from the speaker diaphragm 21 to the side closer to the speaker diaphragm 21 through the speaker hole 11 and enter the interior of the speaker assembly 100 to balance the internal air pressure, allowing the speaker diaphragm 21 to vibrate freely and maintain acoustic stability.

[0033] Simultaneously, by installing the light strip 3 on the side of the mounting plate 1 facing the speaker body 2, the light strip 3 can be fixed to the mounting plate 1. This can be achieved by adhesive or clip-on methods to prevent the light strip 3 from falling off due to gravity, vibration, or external forces, thus avoiding damage. Furthermore, by fixing the light strip 3, the light can be guided to focus on a specific area from a fixed angle, ensuring a fixed illumination range and improving lighting efficiency. Moreover, by installing the light strip 3 towards the speaker body 2, the light emitted by the light strip 3 can be directed towards the speaker body 2, thus providing illumination. The speaker diaphragm 21 is illuminated, and the light strip 3 is configured to reflect light through the speaker diaphragm 21 toward the sound hole 11. That is, the speaker diaphragm 21 has reflective properties. When the light emitted by the light strip 3 shines toward the speaker diaphragm 21, the speaker diaphragm 21 can reflect the light emitted by the light strip 3 toward the sound hole 11, so that the light can shine outward from the sound hole 11, thereby realizing the light-emitting effect of the speaker body 2. This can reduce the need to set the light strip 3 inside the speaker body 2, thereby avoiding the need for redevelopment of the speaker body 2, reducing development costs, and shortening the development cycle.

[0034] According to the speaker assembly 100 of this utility model embodiment, the speaker body 2 can achieve the sound production effect by setting the speaker diaphragm 21, the speaker hole 11 can optimize the acoustic performance, and the light strip 3 is installed on the side of the mounting plate 1 facing the speaker body 2, so that the speaker diaphragm 21 can reflect the light of the light strip 3 to the speaker hole 11, thereby achieving the light emission effect of the speaker body 2, meeting the user's needs, and reducing the need to set the light strip 3 inside the speaker body 2, thereby avoiding the need for redevelopment of the speaker body 2, reducing development costs, and shortening the development cycle.

[0035] In some embodiments, the mounting plate 1 has a mounting groove 12 formed on the side facing the speaker body 2, the light strip 3 is installed in the mounting groove 12, the mounting groove 12 is provided with a light guide 121, the light guide 121 is configured to open in the direction away from the sound hole 11, and the light guide 121 is used to guide the light of the light strip 3 to the speaker diaphragm 21.

[0036] Specifically, the light strip 3 is installed on the side of the mounting plate 1 facing the speaker body 2. A mounting groove 12 is formed on the side of the mounting plate 1 facing the speaker body 2. The mounting groove 12 has a certain space to provide space for the light strip 3, so that the light strip 3 can be installed in the mounting groove 12 and fixed to prevent the light strip 3 from falling off due to gravity, vibration or external force, thereby preventing damage to the light strip 3. Since the mounting groove 12 is formed on the side of the mounting plate 1 facing the speaker body 2, the mounting groove 12 is configured to be open towards the speaker body 2, so that the light strip 3 can be installed in the mounting groove 12 from the open side of the mounting groove 12, and the light strip 3 can be set towards the speaker body 2, so that the light from the light strip 3 can shine towards the speaker body 2.

[0037] Meanwhile, the mounting groove 12 is provided with a light guide 121, which is used to connect the internal space of the mounting groove 12 with the external space so that the light of the light strip 3 located in the mounting groove 12 can be irradiated outward from the mounting groove 12 through the light guide 121. The light guide 121 is set to open in the direction away from the speaker hole 11, that is, the light guide 121 is set on the open side of the mounting groove 11, that is, the light guide 121 is constructed to open in the direction close to the speaker body 2. In this way, when the light strip 3 is installed in the mounting groove 12, the light emitted by the light strip 3 can be irradiated from the light guide 121 in the direction close to the speaker body 2, that is, in the direction close to the speaker diaphragm 21.

[0038] Furthermore, the light guide 121 is used to guide the light from the light strip 3 to the speaker diaphragm 21. That is, when the light from the light strip 3 passes through the light guide 121, the light guide 121 can guide the light from the light strip 3. In this way, the illumination range of the light from the light strip 3 towards the outside of the mounting groove 12 can be adjusted by changing the size of the light guide 121. In turn, the illumination range of the light from the light strip 3 on the speaker body 2 can be adjusted, which can also adjust the illumination range of the light reflected from the speaker diaphragm 21, thereby changing the size of the light-emitting range of the speaker body 2 so that the light-emitting range can be adapted to the size of the speaker hole 11 and avoid uneven brightness.

[0039] In some embodiments, the mounting groove 12 is configured as an annular groove, which surrounds the speaker hole 11; wherein there are multiple light strips 3, and the multiple light strips 3 are distributed sequentially along the circumference of the mounting groove 12; or, the light strip 3 is configured as an annular light strip 3, and the annular light strip 3 extends along the circumference of the mounting groove 12.

[0040] Specifically, the mounting groove 12 is used to install the light strip 3. The mounting groove 12 is constructed as an annular groove and is set around the speaker hole 11. This allows the mounting groove 12 to have a certain length along the circumference of the speaker hole 11, which can increase the setting length of the light strip 3, thereby increasing the lighting distance and range of the light strip 3.

[0041] There can be multiple light strips 3, that is, the number of light strips 3 can be two, three or more. The multiple light strips 3 are distributed sequentially along the circumference of the mounting groove 12, so that the light strips 3 are evenly distributed along the extension path of the annular groove. This can increase the setting length of the light strips 3 and avoid interference between adjacent light strips 3, thereby improving lighting efficiency and avoiding uneven brightness.

[0042] Alternatively, the light strip 3 can be constructed as a ring light strip, and the ring light strip can be extended along the circumference of the mounting groove 12. The ring light strip 3 can be set along the extension path of the ring groove, so that the ring light strip can be set around the speaker hole 11. This can increase the setting length of the light strip 3, and the ring light strip can emit light from any angle in the circumference of the speaker hole 11 towards the speaker body 2 at the same time, which can effectively avoid uneven brightness.

[0043] In some embodiments, the mounting groove 12 has an inner sidewall 122 and an outer sidewall 123 that are relatively distributed, with the inner sidewall 122 located inside the outer sidewall 123; wherein the inner sidewall 122 is configured as an inclined sidewall, which is configured to extend obliquely in a direction close to the speaker body 2.

[0044] Specifically, such as Figure 1 As shown, the light strip 3 is disposed in the mounting groove 12. The mounting groove 12 has an inner sidewall 122 and an outer sidewall 123 that are relatively distributed. The inner sidewall 122 is located inside the outer sidewall 123, so that the inner sidewall 122 and the outer sidewall 123 are spaced apart in the inward and outward directions, so that there is a certain distance between the inner sidewall 122 and the outer sidewall 123, so that the light strip 3 can be disposed between the inner sidewall 122 and the outer sidewall 123. Thus, the light strip 3 can be installed in the mounting groove 12. Moreover, the mounting groove 12 is disposed around the speaker hole 11, that is, the inner side can be the direction that is close to the speaker hole 11 along the radial direction of the speaker hole 11, and the outer side can be the direction that is away from the speaker hole 11.

[0045] The inner sidewall 122 is constructed as an inclined sidewall, meaning that the inner sidewall 122 is constructed to have a certain angle with the mounting plate 1, so that the inner sidewall 122 can be inclined relative to the mounting plate 1. The inclined inner wall is constructed to extend inclinedly in the direction close to the speaker body 2, that is, the inner sidewall 122 can extend inclinedly in the direction along the mounting plate toward the speaker body 2, which also allows one end of the inner sidewall 122 to be inclined away from the outer sidewall 123, which can increase the distance between one end of the inner sidewall 122 and the outer sidewall 123, so as to facilitate the placement of the light strip 3 in the mounting groove 12.

[0046] In some embodiments, the mounting groove 12 further has a bottom wall 124 connected between the inner side wall 122 and the outer side wall 123, the light guide 121 is distributed opposite to the bottom wall 124, and the light strip 3 is located in the area of ​​the mounting groove 12 away from the bottom wall 124.

[0047] Specifically, the mounting groove 12 is constructed in the shape of a groove. In addition to having relatively distributed inner sidewalls 122 and outer sidewalls 123, the mounting groove 12 also has a bottom wall 124 connected between the inner sidewalls 122 and outer sidewalls 123. The two ends of the bottom wall 124 can be connected to the inner sidewalls 122 and outer sidewalls 123 respectively, so that the inner sidewalls 122, outer sidewalls 123 and bottom wall 124 can together form the mounting groove 12. The inner sidewalls 122 and outer sidewalls 123 have a certain height relative to the bottom wall 124, so that the inside of the mounting groove 12 can have a certain depth to ensure reliable accommodation of the light strip 3.

[0048] Furthermore, the mounting groove 12 is formed with a light guide 121, which is distributed opposite to the bottom wall 124 of the groove. That is, the light guide 121 and the bottom wall 124 are located at opposite ends of the inner wall 122 and outer wall 123, respectively. This means that the end of the inner wall 122 furthest from the bottom wall 124 and the end of the outer wall 123 furthest from the bottom wall 124 are spaced a certain distance apart, allowing the inner wall 122 and outer wall 123 to jointly define the light guide 121. The light guide 121 is opened towards the direction closest to the speaker body 2. This means the light guide 121 is formed at the end of the inner wall 122 and outer wall 123 closest to the speaker body 2, and the bottom wall 124 is located at the end of the inner wall 122 and outer wall 123 furthest from the speaker body 2, thus avoiding interference between the bottom wall 124 and the light guide 121 and ensuring the reliability of the light guide 121 in guiding the light from the light strip 3. Furthermore, the light strip 3 is located in the area of ​​the mounting groove 12 away from the bottom wall 124 of the groove. This means that the light strip 3 can be set in the area of ​​the mounting groove 12 near the light guide port 121, so that the distance between the light strip 3 and the light guide port 121 is relatively close. This allows the light from the light strip 3 to shine towards the speaker body 2 through the light guide port 121, and avoids the inner wall 122 and / or the outer wall 123 from blocking the light from the light strip 3, which would result in poor light emission effect of the speaker body 2.

[0049] In some embodiments, the speaker diaphragm 21 and the speaker hole 11 are distributed opposite to each other along a first direction; wherein, in the projection along the first direction, the projection of the speaker diaphragm 21 is located within the projection of the light strip 3, and the central region of the speaker diaphragm 21 coincides with the central region of the light strip 3.

[0050] Specifically, the speaker diaphragm 21 and the speaker hole 11 are distributed opposite each other along a first direction. When the speaker assembly 100 is applied to a vehicle, the first direction can be the lateral direction of the vehicle, and the speaker hole 11 can be set on the side of the speaker diaphragm 21 facing the vehicle interior along the lateral direction of the vehicle. In this way, the speaker hole 11 can be set towards the occupants, so that the sound emitted by the speaker body 2 can be transmitted into the vehicle interior through the speaker hole 11, providing the occupants with an auditory enjoyment. At the same time, the light from the light strip 3 can also be reflected by the speaker diaphragm 21 towards the speaker hole 11, providing the occupants with a visual enjoyment. This can meet the user's needs and help improve user satisfaction.

[0051] Furthermore, in the projection along the first direction, the projection of the speaker diaphragm 21 is located within the projection of the light strip 3. That is, when the light from the light strip 3 shines on the speaker diaphragm 21, the light from the light strip 3 can be focused towards the speaker diaphragm 21 to ensure the brightness of the light reflected by the speaker diaphragm 21 and to avoid uneven brightness. Moreover, the central area of ​​the speaker diaphragm 21 coincides with the central area of ​​the light strip 3, so that the speaker diaphragm 21 and the light strip 3 can be set completely opposite to each other, so that the distance between the light strip 3 and the speaker diaphragm 21 in the circumferential direction of the speaker diaphragm 21 is equal everywhere. This makes the light shining from the light strip 3 onto the speaker diaphragm 21 more uniform and effectively avoids uneven brightness.

[0052] Furthermore, the speaker diaphragm 21 can be positioned directly opposite the sound hole 11, allowing the light reflected by the speaker diaphragm 21 to pass directly through the sound hole 11. This reduces energy loss due to reflection, refraction, or scattering, thus preventing light leakage and maximizing light utilization.

[0053] In some embodiments, the light from the light strip 3 is reflected by the speaker diaphragm 21 to the mounting plate 1 to form an illumination area 4; wherein there are multiple speaker holes 11, and the multiple speaker holes 11 are spaced apart and distributed in the illumination area 4.

[0054] Specifically, the light from the light strip 3 can be reflected by the speaker diaphragm 21 to the mounting plate 1 to form an illumination area 4. The illumination area 4 is the coverage range of the light reflected by the speaker diaphragm 21 on the mounting plate 1. The coverage range of the light from the light strip 3 on the speaker diaphragm 21 can be changed by changing the size of the light guide 121, thereby changing the illumination range of the light reflected by the speaker diaphragm 21 on the mounting plate 1 to adapt to different sizes of the speaker holes 11. When the area of ​​the speaker hole 11 is large, the illumination range can be larger to cover the speaker hole 11 as much as possible. When the area of ​​the speaker hole 11 is small, the illumination range can be smaller to increase the brightness of the light while covering the speaker hole 11.

[0055] Among them, there are multiple sound holes 11, that is, the number of sound holes 11 can be two, three or more, so that the light reflected by the speaker diaphragm 21 can shine out from multiple sound holes 11 at the same time, thereby improving the reliability of the light shining towards the sound holes 11. The multiple sound holes 11 are distributed in the illumination area 4 at intervals, such as the multiple sound holes 11 can be arranged in an array, so that the reflected light can shine on multiple sound holes 11 at the same time, thereby increasing the coverage of the light and thus increasing the area of ​​the light-emitting area.

[0056] In some embodiments, the speaker diaphragm 21 is made of a reflective material; or, the surface of the speaker diaphragm 21 facing the light strip 3 is provided with a reflective layer.

[0057] Specifically, the speaker diaphragm 21 can reflect the light from the light strip 3 toward the sound hole 11. The speaker diaphragm 21 can be made of a reflective material, such as glass fiber with added reflective particles, so that the speaker diaphragm 21 can have reflective properties, ensuring that the speaker diaphragm 21 can reflect the light from the light strip 3 toward the sound hole 11, so as to achieve the light-emitting effect of the speaker body 2.

[0058] Alternatively, a reflective layer can be provided on the surface of the speaker diaphragm 21 facing the light strip 3. For example, a high refractive index medium can be coated on the speaker diaphragm 21 to form a reflective layer on the surface of the speaker diaphragm 21. The reflective layer is provided on the side of the speaker diaphragm 21 facing the light strip 3, so that when the light from the light strip 3 shines on the speaker diaphragm 21, it can shine on the reflective layer, so that the reflective layer can further reflect the light toward the sound hole 11, thereby achieving the light-emitting effect of the speaker body 2.

[0059] Additionally, it should be noted that the light strip 3 can be snapped into the mounting slot 12. For example, a buckle can be set on one of the light strip 3 and the mounting slot 12, and a slot can be set on the other, so as to achieve reliable fixation of the light strip 3.

[0060] This utility model also proposes a car door structure.

[0061] The door structure according to the present utility model includes a door body, a door interior panel and a speaker assembly 100 of any of the above embodiments. The door interior panel is connected to the inside of the door body, and the speaker body 2 is located on the side of the door interior panel facing the door body. The door interior panel is constructed as a mounting plate 1.

[0062] Specifically, the door structure is connected to the vehicle body laterally along the vehicle and can play a role in sound insulation, heat insulation and safety protection. The door structure includes the door body, the door interior panel and the speaker assembly 100. The door body is the basic skeleton of the door structure and can be used to connect the door interior panel, so that the door structure can be a whole structure, which can improve the overall structural strength of the door structure and the reliability of protecting the occupants.

[0063] Furthermore, the door interior panel is connected to the inside of the door body, allowing the door body and the door interior panel to be distributed laterally along the vehicle. The door interior panel is located on the inside of the door body along the vehicle's lateral direction, and the door interior panel is constructed as a mounting plate 1. The speaker body 2 is located on the side of the door interior panel facing the door body. This allows the speaker body 2 and the mounting plate 1 to be distributed opposite each other laterally along the vehicle's lateral direction. The speaker diaphragm 21 can reflect the light from the light strip 3 toward the sound hole 11, so that it can illuminate the interior of the vehicle through the sound hole 11, achieving the lighting effect of the speaker body 2. This reduces the need to install the light strip 3 inside the speaker body 2, thereby avoiding the need for redevelopment of the speaker body 2, reducing development costs, and shortening the development cycle.

[0064] This utility model also proposes a vehicle.

[0065] The vehicle according to the embodiments of the present invention includes the speaker assembly 100 of any of the above embodiments or the door structure of the above embodiments. By connecting the door body to the door interior panel, the overall structural strength and operational reliability of the door structure can be improved. Furthermore, by installing a light strip 3 on the door interior panel and placing the speaker body 2 on the side of the door interior panel facing the door body, the light emitted by the light strip 3 can be reflected by the speaker diaphragm 21 toward the sound hole 11, thereby achieving the light-emitting effect of the speaker body 2. This reduces the need to install the light strip 3 inside the speaker body 2, thus avoiding the need for redevelopment of the speaker body 2, reducing development costs, and shortening the development cycle.
