[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a modular mini Bluetooth speaker, including a base 1, on the top of which multiple speaker units 2 are placed; each of the four corners of the bottom of each speaker unit 2 is fixedly mounted with a support leg 3, and the top of the base 1 has multiple limiting grooves corresponding to the support legs 3, with each support leg 3 fitting into the corresponding limiting groove; a control motherboard is fixedly mounted inside the base 1, and the control motherboard is equipped with a Wi-Fi module and a Bluetooth module. The Wi-Fi module distributes audio to each speaker unit 2 via Wi-Fi to achieve synchronized playback; the Bluetooth module is used for wireless connection with a user's mobile terminal.

[0026] The speaker 2 is equipped with a motherboard, a speaker and a battery. The speaker and battery are electrically connected to the motherboard. The motherboard is equipped with a wireless receiving module. The battery enables the speaker 2 to be used independently when it is detached from the base 1, improving its portability.

[0027] The inner bottom surface of each limiting groove is equipped with a magnetic suction plate 4, and the bottom end of each support leg 3 is provided with a corresponding metal plate 5. The magnetic suction plate 4 and the metal plate 5 are magnetically connected, which can ensure that the speaker 2 is firmly connected to the base 1 during use and reduce the risk of poor contact.

[0028] Among them, a pickup ambient light 6 is vertically installed at the top of the base 1 and between two adjacent groups of speakers 2. Multiple power indicator lights 7 are provided at the top of each speaker 2. The pickup ambient light 6 can change with the rhythm of the music, enhance the immersive experience and improve the aesthetic value of the product; the power indicator lights 7 can intuitively display the remaining power.

[0029] The base 1 is electrically connected to a power cord 8 on one side. A power plug 9 is fixedly installed at the end of the power cord 8 away from the base 1. The power cord 8 is electrically connected to the control motherboard. The base 1 can provide centralized power, avoiding the hassle of charging multiple speakers 2 separately and the occurrence of tangled charging cables.

[0030] The speaker 2 has two sets of connecting slots at its bottom, each slot containing a metal contact that is electrically connected to the main board inside the speaker 2. The base 1 has a spring pin 10 connected to the metal contact at its top, with one end of each spring pin 10 electrically connected to the main board. A waterproof sealing ring is attached to the top of the base 1, outside the spring pin 10. The spring pin 10 uses elastic pressure to ensure stable contact with the metal contact, facilitating power supply. The waterproof sealing ring protects against everyday humidity and extends the speaker's lifespan.

[0031] The base 1 has a capacitive touch panel 11 on its outer side, and an integrated light strip 12 below the capacitive touch panel 11. The capacitive touch panel 11 supports sliding to adjust the volume and tapping to switch modes, with a fast operation response speed, which is better than traditional physical buttons. At the same time, the light strip 12 below it can provide illumination for the operation area, improving the user experience in low-light environments.

[0032] The base 1 has four fixed support feet 13 at its bottom corners. The support feet 13 can provide support for the base 1 and effectively absorb the vibration of the speaker 2, reducing noise generated by resonance with the desktop.

[0033] The working principle of this embodiment:

[0034] When multiple speaker units 2 need to be placed on the base 1 for combined use, the user first takes out the speaker unit 2 and places it on the top of the base 1. During placement, the metal plate 5 at the bottom of the support leg 3 of the speaker unit 2 and the magnetic plate 4 in the limiting groove of the base 1 magnetically attract each other, achieving a tight connection and ensuring stability during use. When the speaker unit 2 is placed on the base 1, the contact between the spring pin 10 and the metal contact enables power transmission, allowing the base 1 to charge the speaker unit 2. At the same time, the waterproof sealing ring on the outside of the spring pin 10 fits tightly with the bottom of the speaker unit 2, forming a waterproof barrier to prevent liquid from seeping into the internal circuit of the base 1 and protecting the control board and other precision components. Then, the power plug 9 is inserted into the power supply device, and the external power is transmitted to the base 1 through the power cord 8, and the power is distributed to the inside of each speaker unit 2 through the spring pin 10 at the top of the base 1.

[0035] Next, the user pairs the Bluetooth module of the control motherboard of the base 1 with a mobile terminal (such as a mobile phone). After the audio signal is transmitted to the control motherboard via Bluetooth, the Wi-Fi module synchronously distributes the signal to the wireless receiving module of each speaker 2, so as to realize synchronous playback of multiple speakers 2.

[0036] Users can then adjust the volume, switch playback modes, or control the ambient light 6 via the capacitive touch panel 11. After the touch operation signal is transmitted to the control motherboard, it coordinates the various functional modules to perform the corresponding operations. The light strip 12 can display different lighting effects according to the music rhythm or operation commands, and the power indicator 7 displays the battery status of each speaker 2 in real time.

[0037] When speaker 2 needs to be taken out and used, it can be taken out from the top of base 1. At the same time, the battery inside speaker 2 allows speaker 2 to be placed and used independently when it is detached from base 1, so as to improve the audio playback space effect.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
