[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Please refer to Figures 1 to 3 An embodiment of the present invention provides a speaker, including a box shell 10, a speaker assembly 20, a passive disk 30, a box bracket 40, a ventilation bracket 50, a sound grille 60 and a display screen 70.

[0030] Please refer to Figure 2 The housing 10 is cylindrical and has a mixing chamber 101. When in use, the housing 10 extends vertically and has a bass hole 102 and a sound inlet 103 at each end, both connected to the mixing chamber 101. The bass hole 102 and the sound inlet 103 are spaced apart, forming an airflow channel from the sound inlet 103 to the bass hole 102 for the flow of air generated by vibration. The housing 10 may also be a square cylinder or any other shape.

[0031] Please refer to Figure 2 and Figure 3 The speaker assembly 20 is connected to the box shell 10 and covers the sound guide hole 103. The speaker assembly 20 includes a speaker bracket 22 connected to the box shell 10 and at least two speakers 21 connected to the speaker bracket 22 and used to play audio. The sound output direction of the speaker 21 faces outward so that the user can clearly hear the sound it produces. The speaker bracket 22 is provided with a plurality of support holes, and a speaker 21 is installed at a support hole. The speaker bracket 22 is used to support and connect each speaker 21, and to arrange each speaker 21 at intervals. Each speaker 21 can be arranged along the extension direction of the box shell 10, so that each speaker 21 emits sound in the same direction and cannot take into account the sound effects in other directions. In order to enable the user to hear the sound in all directions and maintain good sound effects, each speaker 21 is distributed in a ring shape and its sound output direction is all facing the horizontal direction. In this way, if the speaker is played indoors, the sound can fill the entire room, and the user can get a high-quality music experience at any position.

[0032] Please refer to Figure 2 and Figure 3 The passive disc 30 is capable of vibrating under the influence of sound pressure. It is connected to the enclosure 10 and covers the bass port 102. The enclosure 10, speaker assembly 20, and passive disc 30 together enclose a sealed space. The speaker 21 vibrates the air within the sealed space, causing the air to vibrate the passive disc 30 under the influence of sound pressure. The passive disc 30 then vibrates the surrounding air, producing a bass effect. If the space enclosed by the enclosure 10, speaker assembly 20, and passive disc 30 is not sealed, the sound pressure will be dispersed outward and will not be easily transmitted to the passive disc 30, or the sound pressure transmitted to the passive disc 30 will be very small, affecting the bass effect.

[0033] The speaker of the present invention forms a sealed space by enclosing the box shell 10, the speaker assembly 20 and the passive disk 30 together, so that the speaker 21 can drive the air in the sealed space to vibrate when playing audio. The mixing chamber 101 is also provided so that the displacement of the vibrating airflow generated by each speaker 21 can be mixed and balanced in the mixing chamber 101. Under the action of the already balanced vibrating airflow, the passive disk 30 regularly and rhythmically agitates, pushing the air and transmitting the vibration into the human ear, creating a bass sound effect. The speaker of the present invention replaces the traditional subwoofer to produce bass through the mixing chamber 101 and the passive disk 30. The mixing chamber 101 can not only automatically balance the displacement of the vibrating airflow of each speaker 21, but also can make the sound pressure of each speaker 21 overlap, increase the vibration amplitude of the passive disk 30, make the bass fuller, the bass effect more outstanding, simple structure, and reduce production costs.

[0034] The frequency of sound can generally be divided into eight frequency points, namely, sub-bass, bass, mid-bass, mid-range, mid-treble, sub-treble, treble and very treble. For example, 20HZ to 20kHZ are divided into eight frequency points. In this embodiment, preferably, each speaker 21 is used to play audio of different frequencies in the mid-range frequency point and above, so that the audio of each frequency point can be fully presented, and together the entire audio can be restored more realistically, achieving lossless high-quality playback effect. However, the airflow displacement generated by the vibration of the speaker 21 playing audio of different frequencies is also different. If the mixing chamber 101 is not provided, the air vibration in the sealed space will be chaotic, and the sound pressure in each area will be unbalanced, which will easily lead to the vibration disorder of the passive disk 30 and the unstable bass rhythm, affecting the bass effect. Please refer to Figure 1 and Figure 3 To address this issue, the present speaker enclosure has a cylindrical housing 10, with the passive disc 30 positioned opposite the sound guide hole 103. The speakers 21 are evenly distributed around the circumference of the speaker bracket 22. This ensures that the distances between each speaker 21 and the passive disc 30 are equal, allowing the vibrating airflow generated by each speaker 21 to be fully mixed over the same transmission distance, resulting in a balanced and rhythmic vibration of the passive disc 30. If the distances between each speaker 21 and the passive disc 30 were unequal, the vibrating airflow generated by each speaker 21 would likely be unevenly mixed, causing irregular vibration of the passive disc 30 and poor bass performance.

[0035] Please refer to Figure 2Preferably, the speaker bracket 22 and the multiple speakers 21 together form a avoidance cavity 201 connected to the mixing cavity 101, and the avoidance cavity 201 and the mixing cavity 101 together form the above-mentioned sealed space. The airflow displacement generated by each speaker 21 is preliminarily mixed in the avoidance cavity 201 and blended to a balanced state in the mixing cavity 101. The avoidance cavity 201 not only expands the size of the sealed space and increases the distance between each speaker 21 and the passive disk 30, making the bass effect more outstanding, but also reduces the height of the box shell 10 under the condition of the same playback effect, making the speaker more compact and saving space. At the same time, the avoidance cavity 201 can also be used to arrange the electrical connection wires of the speaker 21, and also plays a certain heat dissipation role.

[0036] Please refer to Figure 2 and Figure 3 In this embodiment, the speaker 21 includes a magnetic circuit mechanism 211 for converting electrical signals into magnetic signals and a vibration mechanism 212 for converting magnetic signals into sound signals through vibration. The magnetic circuit mechanism 211 is located in the avoidance cavity 201, and the vibration mechanism 212 is connected to the support hole to transfer vibration energy through the air in the sealed space to the air in the mixing cavity 101. The magnetic circuit mechanism 211 includes a magnet for generating a magnetic field, a U iron for increasing the magnetic field, and a washer for conducting magnetism. The vibration mechanism 212 includes a voice coil for conducting electricity and a diaphragm for vibrating. The diaphragm is connected to the speaker bracket 22 and covered by the support hole. The vibration of the diaphragm can drive the air inside and outside the diaphragm to vibrate. The vibration of the air outside causes the human ear to hear sound, and the vibration of the air inside is transmitted to the mixing cavity 101 and drives the passive disk 30 to vibrate, thereby producing bass.

[0037] Please refer to Figure 2 and Figure 3The cabinet stand 40 is used to support the cabinet housing 10 and the speaker assembly 20 off the ground, thereby maintaining the balance of the speaker. The cabinet stand 40 includes a frame body 41 made of a tough material, a frame base 42 for placement on the ground, and a top cover 43 positioned above the speaker assembly 20. The bottom surface of the frame base 42 is provided with a non-slip pad 421 for preventing slipping. The frame body 41 is connected to the frame base 42 and extends upward, and the top cover 43 is connected to the extended end of the frame body 41. The speaker assembly 20 is connected to the side of the frame body 41 via the cabinet housing 10. The frame base 42 can be positioned directly opposite the speaker assembly 20, allowing the speaker assembly 20 to be stably suspended on the cabinet stand 40. The frame body 41 can separate the speaker assembly 20 from the ground. Because it is made of a tough material, it can absorb the vibration energy of the speaker assembly 20, thereby reducing the vibration of the frame base 42, preventing wear of the speaker housing due to constant vibration hitting the ground, and reducing the noise generated between the speaker and the ground. The tough material is preferably stainless steel, which can absorb vibrations while preventing the box bracket 40 from rusting. Preferably, the box bracket 40 is a box bracket 40 made of one-piece stainless steel material, that is, the frame body 41, the frame base 42 and the top cover 43 are all made of stainless steel, which is easy to process, has strong stability and is not easy to break. The top cover 43 is located above the speaker assembly 20 and is used to prevent dust from falling on the speaker assembly 20. The frame base 42 is preferably annular, which increases the support area while reducing the weight of the box bracket 40. The anti-slip pad 421 can be a rubber pad, which is anti-slip and can absorb a certain amount of vibration energy.

[0038] Please refer to Figure 2 and Figure 3 The breathable bracket 50 is connected to the speaker assembly 20 and is used to prevent the speaker 21 from collecting dust. The breathable bracket 50 includes a support frame connected to the speaker assembly 20 and covering the speaker 21, and a breathable membrane wrapped around the support frame. The support frame is in a grid shape to avoid blocking the passage of airflow, and it is used to support the flexible breathable membrane. The breathable membrane can block large particles of dust and insects without affecting the sound of the speaker 21. In this embodiment, the support frame is in a cover shape and covers the speaker bracket 22. The breathable membrane is a breathable membrane made of textile material, preferably a fabric that is easily available in daily life, which saves costs while being breathable and dust-proof.

[0039] Please refer to Figure 2 and Figure 3The sound grille 60 is connected to the outer shell 10 in a hood-like shape and covers the vent bracket 50. The sound grille 60 is made of a hard material and has gaps that allow air to pass through. It also provides protection against damage to the speaker assembly 20. In this embodiment, the sound grille 60 also serves as the base of the speaker to support the outer shell 10, so that the passive disc 30 faces upward. In this way, when the passive disc 30 vibrates, the airflow it generates is not blocked by the ground or walls, and the bass sound effect can fill the entire room, providing users with a better music experience.

[0040] Please refer to Figure 1 and Figure 3 The display screen 70 is connected to the housing 10 and electrically connected to the speaker assembly 20. It can display a playlist, an operation interface, or a video screen, enabling the speaker to achieve multi-functional operation and providing a better user experience. In this embodiment, the display screen 70 is a curved touch screen having a curved structure extending around the circumference of the housing 10. The curved touch screen is connected to the housing 10 and avoids the speaker assembly 20. The curved touch screen is electrically connected to the speaker assembly 20 and is used for user touch operation to control the speaker assembly 20. By providing a curved touch screen having a curved structure and extending around the circumference of the housing 10, the user can see the displayed image along the circumference of the housing 10, making it easier for the user to view and operate the screen from different positions, thereby enhancing the human-computer interaction effect and optimizing the user experience.

[0041] Please refer to Figure 3 Specifically, the curved touch screen includes a support housing 71, a touch module 72 connected to the support housing 71, and a translucent protective film 73 covering the touch module 72. The support housing 71 is circumferentially wrapped around the housing 10. The support housing 71 is circumferentially wrapped around the housing 10. The touch module 72 is used to sense the user's touch area and transmit control commands corresponding to the touch area to the speaker 21 to control the speaker 21 and adjust the audio playback parameters of the speaker 21. The translucent protective film 73 is used to prevent the touch module 72 from dust and scratches from the outside and also has a waterproof function.
