[0037] Reference Figure 1-6 This utility model provides a speaker, including a shell 1, a speaker 2, a passive radiator 3, a top plate 4, a preamplifier circuit board 5, a power supply board 6, and a power amplifier circuit board 7.

[0038] The outer casing 1 is the main body of the speaker, and all internal components are housed within it. The power board 6 provides power to the speaker. The preamplifier circuit board 5 and the power amplifier circuit board 7 are connected, and the power amplifier circuit board 7 is connected to the speaker 2. The preamplifier circuit board 5 processes the input signal, raising the signal level to a higher level to provide a stronger signal to the power amplifier circuit board 7. The power amplifier transmits the electrical signal to the speaker 2, and the speaker 2 converts the electrical signal into sound. The passive radiator 3 works by relying on passive responses such as vibration, which can enhance the bass effect of the speaker. The top plate 4 works in conjunction with the speaker 2 to improve the sound propagation range of the speaker 2. It should be noted that the circuitry and connection structures of the preamplifier circuit board 5, the power amplifier circuit board 7, and the power board 6 can all adopt existing technologies, and will not be described in detail in this application.

[0039] Both the speaker 2 and the passive radiator 3 are housed within the outer casing 1, with the speaker 2 positioned at the upper end of the casing 1 and the passive radiator 3 at the lower end. When the speaker emits sound, not only does the speaker 2, located at the upper end of the speaker, produce better sound quality, but the passive radiator 3 at the lower end also enhances the overall bass response of the speaker.

[0040] Specifically, the upper end of the outer casing 1 has a first circular groove 11 and a first receiving groove 12. The first receiving groove 12 is connected to the interior of the outer casing 1 through the first circular groove 11. The speaker 2 can be inserted through the first circular groove 11, and the edge of the speaker 2 is mounted in the first receiving groove 12. Bolts or other fasteners can be driven into the outer casing 1 to fix the speaker 2 in the first receiving groove 12, so that the speaker 2 can be stably installed above the speaker box and can be embedded in the outer casing 1, reducing the overall height of the speaker box.

[0041] The lower end of the outer casing 1 is provided with a second circular groove 13 and a second receiving groove 14. The second receiving groove 14 is connected to the interior of the outer casing 1 through the second circular groove 13. The passive radiator 3 is inserted through the second circular groove 13. The edge of the passive radiator 3 can be placed in the second receiving groove 14, so that the passive radiator 3 can be stably fixed under the speaker and save space.

[0042] The top plate 4 is fixed to the upper end of the outer casing 1, and a gap is provided between the top plate 4 and the outer casing 1. The top plate 4 is located above the speaker 2, and the speaker 2 is oriented upwards. It should be noted that the direction of the speaker 2 can be adjusted according to the fine adjustment of the position of the top plate 4, as long as the direction of its sound emission is towards the top plate 4.

[0043] In the speaker of this application, the speaker 2 is placed on top of the speaker, and the passive radiator 3 is placed inside the outer casing 1, below the speaker 2. This makes the speaker have better sound performance and bass effect than a single bottom-mounted speaker when it emits sound. In addition, together with the top plate 4, it can improve the sound propagation range and enhance the overall user experience of the speaker.

[0044] As one embodiment, multiple columns 15 are fixed to the upper end of the outer shell 1, and the top plate 4 is fixed to the upper end of the columns 15, so that there is a gap between the top plate 4 and the outer shell 1, which is simple in structure and reasonable in distribution.

[0045] As one embodiment, a plurality of suction cup feet 16 are fixed to the lower end of the outer casing 1. The suction cup feet 16 can adhere the speaker to the tabletop, preventing displacement caused by speaker vibration, and can also appropriately raise the height of the lower end of the outer casing 1 to improve the effect of the passive radiator 3.

[0046] A mounting groove 17 is provided on one side of the outer casing 1. A sealing gasket 8 is fixed inside the outer casing 1 at the position corresponding to the mounting groove 17. The side of the sealing gasket 8 closest to the outer casing 1 is curved, allowing the sealing gasket 8 to abut against the interior of the outer casing 1. The side of the sealing gasket 8 away from the side wall of the outer casing 1 is flat. A mounting plate 81 is fixed to the side of the sealing gasket 8 away from the side wall of the outer casing 1. The mounting plate 81 can be used to fix the preamplifier circuit board 5. The preamplifier circuit board 5 is provided with multiple interfaces, which can extend and be fixed to the mounting plate 81. The interfaces can be located within the mounting groove 17. The type of interface is not limited and can be a charging port or an audio input / output port. By setting the sealing gasket 8, a flat surface for fixing the mounting plate 81 is provided, reducing the difficulty of processing and installation.

[0047] As one embodiment, the mounting plate 81 includes a first part 811 and a second part 812. The first part 811 and the second part 812 are connected to each other and are inclined. The preamplifier circuit board 5 is fixed to the first part 811, and the power amplifier circuit board 7 and the power supply board 6 are both disposed on the second part 812, so that the circuit boards can be neatly placed inside the housing 1, reducing the volume of the speaker.

[0048] Furthermore, the mounting plate 81 can be a metal plate, which can improve the heat dissipation of the power amplifier circuit board 7, the preamplifier circuit board 5 and the power supply board 6.

[0049] In one embodiment, a decorative panel 9 is provided on the outer side of the outer casing 1 corresponding to the mounting groove position, and the inner side of the decorative panel 9 can abut against the outer wall of the outer casing 1. Multiple through grooves 18 are arranged around the outer periphery of the outer casing 1 corresponding to the mounting groove 17. Multiple first sleeves 82 are fixed to one side of the sealing gasket 8, and multiple second sleeves 91 are fixed to one side of the decorative panel 9. Both the first sleeves 82 and the second sleeves 91 can be inserted into the through grooves 18. The first sleeves 82 have threaded holes 821, and the second sleeves 91 have insertion holes 911. Bolts that can be threaded into the threaded holes 821 can be inserted into the insertion holes 911, thereby fixing the decorative panel 9 and the sealing gasket 8 to the outer casing 1. Furthermore, bolts with a screw length extending to the mounting portion can be used to fix the decorative panel 9, the sealing gasket 8, and the mounting plate 81 together, facilitating installation.

[0050] Furthermore, the decorative panel 9 is a ring-shaped plate, and an inner ring 92 is fixed on the inner circle of the decorative panel 9. The inner ring 92 can be inserted into the inner circumference of the mounting groove 17 and the sealing gasket, and abut against the side wall of the mounting groove 17 and the inner side of the sealing gasket 8, so that the decorative panel 9 can completely cover the mounting groove 17 and improve the cleanliness of the speaker's appearance.

[0051] The implementation principle of this utility model is as follows: In the speaker of this application, the speaker 2 is placed above the speaker, and the passive radiator 3 is placed inside the outer shell 1, below the speaker 2. This makes the speaker have better sound performance and bass effect than a single bottom speaker when it emits sound.
