[0038] The interior of the rear shell 4 has a space, the front cover 1 is fitted with the exposed side of the rear shell 4, the front cover 1 is adapted to the rear shell 4 and the space inside the rear shell 4 is a cavity;

[0039] The control panel 6 is arranged on the rear shell 4, the speaker 3, single-chip microcomputer, transmission module and rhythm beater are all integrated on the front cover 1, the control panel 6 is connected to the single-chip microcomputer and transmission module, and the signal interface 7 is arranged on one side of the rear shell 4.

[0040] In this embodiment, the rhythm beater is arranged in the middle of the front cover 1, and the two speakers 3 are arranged in a mirror image relative to the rhythm beater.

[0041] It also includes a primary stud 11, a secondary stud 9 and a bolt 10;

[0042] The primary stud 11 is provided on the front cover 1 , the secondary stud 9 is provided on the speaker 3 , and the bolt 10 is provided on the rear shell 4 . The primary stud 11 is adapted to the secondary stud 9 , and the secondary stud 9 is adapted to the bolt 10 .

[0043] The primary stud 11 is embedded in the secondary stud 9 , the secondary stud 9 is embedded in the bolt 10 , and the primary stud 11 , the secondary stud 9 and the bolt 10 are bonded to each other by glue.

[0044] Specifically, when assembling the audio system, the user can fix the speaker 3, single-chip microcomputer, transmission module and rhythm beater in the internal cavity through the adaptation between the front cover 1 and the rear shell 4, wherein the front cover 1 and the speaker 3 are embedded in the secondary stud 9 through the primary stud 11, and then embedded in the bolt 10 on the rear shell 4 through the secondary stud 9, so that the front cover 1, the speaker 3 and the rear shell 4 are clamped with each other, and after assembly, a complete external structure is formed, which is similar to a rectangular structure.

[0045] In this embodiment, anti-slip grooves 5 are provided on both the left and right sides of the rear shell 4 .

[0046] Specifically, the anti-slip grooves 5 can facilitate customers to grab from both sides, thereby improving friction.

[0047] In this embodiment, a ventilation window 8 is provided on the other side of the rear shell 4 relative to the front cover 1 .

[0048] An external assembly structure based on sound and an electromagnetic beating method, the method comprising:

[0049] Control the magnetic force of the magnetic fluid 2 behind the rhythm beater according to the audio data information;

[0050] Collect sound data information around the speaker through the microphone;

[0051] Convert the collected sound data information and rhythm into electrical signals;

[0052] Control the magnetic force of the electromagnet according to the electrical signal;

[0053] The magnetic fluid 2 achieves different beating rhythms according to the strength of the magnetic force of the electromagnet.

[0054] In this embodiment, in the step of controlling the magnetic force of the magnetic fluid 2 after the rhythm jumper according to the audio data information,

[0055] The magnetic fluid 2 comprises ferroferric oxide particles with a particle size of 10-50 nm, which are suspended in a silicone oil-based carrier liquid with a volume concentration controlled at 15-25%.

[0056] Specifically, by embedding a 5mm thick magnetic fluid container 2 into the transparent acrylic plate of the speaker and arranging 7 groups of circular electromagnet arrays at an equal interval of 20mm at its bottom, the device can achieve dynamic visual effects according to the characteristics of the audio signal: when a low-frequency drum beat of 50-100Hz is input, the central electromagnet is driven by a PWM signal with a duty cycle of 70%-85%, exciting the magnetic fluid 2 to form a vertical liquid column with a height of 10-15cm; and when a high-frequency human voice signal of 2k-5kHz is triggered, the peripheral electromagnets are driven by a PWM signal with a duty cycle of 20%-40%. By alternately activating the magnets, the silicone oil-based ferroferric oxide magnetic fluid 2 (particle size 20nm, volume concentration 18%) produces a circular ripple diffusion effect. Actual measurements show that the system's response time from audio input to magnetic fluid 2 deformation is shortened to less than 50ms, and the rhythm synchronization error with the standard MIDI signal is less than ±3ms. Compared with traditional mechanical vibration solutions, power consumption is reduced by 40% and there is no mechanical wear. Especially under stage lighting, the metallic luster of the magnetic fluid 2 forms a multi-dimensional sensory synchronization with the music beat, making it suitable for upgrading the immersive experience in scenes such as concerts and nightclubs.

[0057] In this embodiment, the amplitude peak value of each frequency band is identified, and a PWM control signal is generated according to a preset duty cycle table.

[0058] The duty cycle table is dynamically modified based on historical audio data, adding 10-15% duty cycle compensation for continuous low-frequency signals and reducing 5-8% duty cycle for transient high-frequency signals to prevent hysteresis effects.

[0059] Specifically, a circular buffer is established to store the audio spectrum data of the last 500ms, and a moving average is calculated for each frequency band. When the amplitude fluctuation rate of the low-frequency band is detected to be less than 5% within 5 consecutive sampling cycles, it is determined to be a continuous low-frequency signal; if the amplitude of the high-frequency band suddenly increases by more than 50% in a single cycle and the duration is less than 20ms, it is determined to be a transient high-frequency signal.
