Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically a miniaturized speaker. Background Technology

[0002] In specific application scenarios such as desktop and embedded systems, speaker design must prioritize aesthetics and installation space constraints. Their vertical height is often limited by the dimensions of drawers, storage compartments, and other spaces, preventing them from being designed too tall. This height limitation directly results in the inability to install large woofer units on the front of the speaker—because if the woofer unit's diameter is larger than the speaker's height, it cannot be properly embedded for front mounting. Large woofers are crucial for ensuring bass performance, and existing solutions have the following significant drawbacks: 1. Using a small-sized woofer with a bass reflex port will result in shallow low-frequency extension, high distortion, and a significant sacrifice in bass performance; 2. Increasing the speaker height to accommodate larger speakers would exceed the space height limit and fail to meet the needs of the scenario; 3. The use of a separate subwoofer does not fundamentally solve the height limitation problem and still cannot adapt to compact installation scenarios. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a miniaturized speaker that can solve the problems described in the background art.

[0004] The technical solution to achieve the purpose of this utility model is as follows: a miniaturized speaker, including a cabinet, a partition and a woofer unit disposed inside the cabinet, the partition being arranged along the direction where the size of the miniaturized speaker is limited by the external environment, so as to divide the cavity inside the cabinet into an upper cavity and a lower cavity, the woofer unit being mounted on the partition and located in the upper cavity, the radial direction of the woofer unit being arranged along a first direction of the cabinet, the first direction being perpendicular to the direction of the limitation. A sound outlet hole is provided on the sound outlet end face of the enclosure. The sound outlet hole is connected to the lower cavity, so that the sound emitted by the woofer unit first passes through the lower cavity, which serves as the sound outlet channel, and then is emitted to the outside through the sound outlet hole. The enclosure is also equipped with a full-range speaker and a second passive bass radiator. Both the full-range speaker and the second passive bass radiator are located in the upper cavity. The second passive bass radiator is mounted on the partition and is located on one side of the bass speaker unit.

[0005] Furthermore, the box body has a rectangular structure, and all four edges of the box body are provided with rounded chamfers.

[0006] Furthermore, the sound-emitting surface of the full-range speaker is embedded and mounted on the sound-emitting end face of the enclosure.

[0007] Furthermore, along the axial direction of the woofer unit, the sound-emitting surface of the woofer unit faces vertically downwards, and the back of the woofer unit is located above the sound-emitting surface.

[0008] Furthermore, it also includes a first passive bass radiator, which is mounted on the enclosure.

[0009] Furthermore, a first mounting hole and a second mounting hole are provided on the partition plate. The second subwoofer unit is embedded in the first mounting hole, and the subwoofer passive radiator is embedded in the second mounting hole.

[0010] Furthermore, the height of the upper cavity is greater than the height of the lower cavity, and the height of the lower cavity is less than its depth, resulting in a flat cavity structure for the lower cavity.

[0011] Furthermore, the enclosure includes a frame, a front panel, and a back panel. The front panel and the back panel are installed on opposite front and rear sections of the frame. The frame, the front panel, and the back panel enclose the enclosure to form the enclosure, and the resulting internal space constitutes the cavity of the enclosure.

[0012] Furthermore, the partition is fixedly or detachably mounted on the inner walls of the frame, front panel, and rear panel.

[0013] Furthermore, both the full-range speaker and the first passive bass radiator are embedded and mounted on the front panel, with the full-range speaker and the first passive bass radiator spaced apart.

[0014] The beneficial effects of this utility model are as follows: By installing the woofer unit along the unrestricted front-to-back direction of the enclosure with the larger diameter of the woofer unit, this utility model allows the woofer unit to be installed without changing its size or increasing the size of the enclosure, thus achieving miniaturization of the enclosure. Furthermore, it does not sacrifice the low-frequency performance of the woofer unit, thereby improving the user experience. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6 As shown, a miniaturized speaker includes a cabinet, a partition 7 and a woofer unit 6 disposed inside the cabinet. The partition 7 is arranged along the direction where the size of the miniaturized speaker is limited by the external environment, so as to divide the cavity inside the cabinet into an upper cavity 10 and a lower cavity 8. The woofer unit 6 is mounted on the partition 7 and located in the upper cavity 10. The radial direction of the woofer unit 6 is arranged along a first direction of the cabinet, which is perpendicular to the direction where the size is limited, that is, the first direction is the direction where the miniaturized size is not limited.

[0017] The sound outlet surface of the enclosure is provided with a sound outlet hole 3, which is connected to the lower cavity 8, so that the sound emitted by the bass speaker unit 6 first passes through the lower cavity 8, which serves as the sound outlet channel, and then is emitted to the outside through the sound outlet hole 3.

[0018] refer to Figure 1 It is understood that, as an example, the miniaturized speaker in this embodiment is limited in height. For example, due to limitations imposed by the external environment such as aesthetics and placement space, the height of this miniaturized speaker needs to be ≤150 mm. The radial diameter of the woofer unit 6 is 165 mm, making it impossible to install the woofer unit 6 radially along the height direction, while the enclosure is not limited in size in the depth and lateral directions. In this embodiment, the woofer unit 6 is installed radially along the depth direction, and the partition 7 is installed in the enclosure along the height direction, thereby dividing the enclosure cavity into an upper cavity 10 and a lower cavity 8 along the height direction.

[0019] refer to Figure 6 It is understandable that the radial dimension (i.e., diameter) of the woofer unit 6 is greater than the axial dimension (i.e., thickness). The height direction of the enclosure restricts the installation of the woofer unit 6. That is, the radial diameter of the woofer unit 6 cannot be installed in the height direction of the enclosure, while the thickness of the woofer unit 6 is smaller and can be installed in the height direction of the enclosure.

[0020] The enclosure is also equipped with a full-range speaker 5 and a second passive bass radiator 9. Both the full-range speaker 5 and the second passive bass radiator 9 are located inside the upper cavity 10. The second passive bass radiator 9 is installed on the partition 7 and is located on one side of the bass speaker unit 6. The sound-emitting surface of the full-range speaker 5 is embedded in the sound-emitting end face of the enclosure, that is, the sound-emitting surface of the full-range speaker 5 and the sound outlet 3 are on the same end face.

[0021] Understandably, the full-range speaker 5 is capable of playing low, mid, and high frequencies, that is, it can play bass, mid, and treble.

[0022] For example, the sound-emitting surface of the bass speaker unit 6 is disposed facing the lower cavity 8, that is, along the axial direction of the bass speaker unit 6, the sound-emitting surface of the bass speaker unit 6 is vertically downward, and the back of the bass speaker unit 6 is located above the sound-emitting surface, that is, the back of the bass speaker unit 6 is disposed upward.

[0023] For example, it also includes a first passive bass radiator 2, the sound-emitting surface of which is also embedded in the sound-emitting end face of the enclosure.

[0024] The first passive bass radiator 2 and the second passive bass radiator 9 are both configured for the bass speaker unit 6 to enhance the bass performance of the bass speaker unit 6.

[0025] For example, the partition 7 has a first mounting hole 11 and a second mounting hole 12. The bass speaker unit 6 is embedded in the first mounting hole 11, and the second bass passive radiator 9 is embedded in the second mounting hole 12.

[0026] For example, the height of the upper cavity 10 is greater than the height of the lower cavity 8, and the height of the lower cavity 8 is less than its depth, so that the lower cavity 8 has a flat cavity structure.

[0027] For example, the enclosure includes a frame 1, a front panel 4, and a back panel 13. The front panel 4 and the back panel 13 are installed on opposite front and rear sections of the frame 1. The frame 1, the front panel 4, and the back panel 13 enclose the enclosure, forming an internal space that constitutes the cavity of the enclosure. A partition 7 is fixedly or detachably installed on the inner wall of the frame 1, the front panel 4, and the back panel 13.

[0028] For example, the full-range speaker 5 and the first passive bass radiator 2 are both embedded in the front panel 4, and the full-range speaker 5 and the first passive bass radiator 2 are spaced apart.

[0029] For example, the box body has a rectangular structure, and all four edges of the box body are provided with rounded chamfers. By providing rounded chamfers, the sharp edges of the box body are prevented from posing a safety hazard to the user.

[0030] This embodiment addresses the pain points mentioned in the background section with the following innovative approach: Utilizing the excellent diffraction performance of bass speakers, a large-size woofer unit is placed horizontally with its sound-emitting surface facing downwards. A dedicated cavity guides the bass to the front of the speaker enclosure for sound emission. This solution fully utilizes the unrestricted width and depth of the speaker enclosure to install a large-size unit, ensuring excellent bass performance without exceeding height limitations and maintaining scene adaptability.

[0031] This invention allows the woofer unit 6 to be installed along the unrestricted front-to-back direction of the enclosure without changing its size or increasing the size of the enclosure. This achieves miniaturization of the enclosure and does not sacrifice the low-frequency performance of the woofer unit 6, thus improving the user experience.

[0032] The embodiments disclosed in this specification are merely illustrative of one aspect of the features of this utility model. The protection scope of this utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of this utility model. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
