Description

Technical Field

[0001] This utility model relates to the field of headphone function expansion technology, and in particular to a multifunctional headphone component and expansion body that supports function expansion. Background Technology

[0002] In existing technologies, wireless audio devices, such as true wireless stereo (TWS) earbuds or open-back wireless stereo (OWS) earbuds, typically integrate multiple functions, including audio playback, communication, and additional features such as image acquisition (e.g., via a built-in camera) and environmental or motion sensors. These additional functional modules are usually tightly integrated with the earbud body through structural design. This integration results in a fixed product form, making it impossible to flexibly expand or replace functions according to specific user needs. For segmented customer markets, this integrated design limits product customization capabilities, making it impossible to provide differentiated functional configurations for specific user groups. For example, if a user only needs basic audio functions, but the device integrates additional functions such as a camera, it not only increases costs but may also introduce unnecessary design complexity and weight. Conversely, if a user needs specific extended functions that existing devices do not possess, a completely new device must be purchased, lacking flexibility and cost-effectiveness. Therefore, existing technologies have limitations in functional integration and cannot meet users' needs for diverse and personalized wireless audio device functions. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional headphone assembly and extender that supports the expansion of additional functions according to user needs.

[0005] The earphone body is equipped with an output-type first power interface;

[0006] An expansion unit, which includes a functional module and an input-type second power interface;

[0007] The first power interface and the second power interface are connected or disconnected through a removable connection structure. When the first power interface and the second power interface are connected, the first power interface provides power to the second power interface so that the functional module in the extension body works under the power output of the headphone body. The functional module is used to perform extended functions independent of the headphone body.

[0008] Preferably, the extender is further provided with a first communication module, which enables the extender to communicate wirelessly with an external electronic device.

[0024] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] This embodiment discloses a multi-functional headphone component that supports functional expansion, such as... Figures 1 to 5 It includes the headphone body 1 and the extension body 2.

[0026] The headphone body 1 is provided with an output-type first power interface 10. The expansion unit 2 includes an input-type second power interface 20 and a functional module 21.

[0027] The first power interface 10 and the second power interface 20 are connected or disconnected via a removable connection structure. When the first power interface 10 and the second power interface 20 are connected, the first power interface 10 provides power to the second power interface 20, enabling the functional module 21 in the expansion body 2 to operate under the power output from the earphone body 1. The functional module 21 is used to perform extended functions independent of the earphone body 1.

[0028] In this embodiment, the functional module 21 includes, but is not limited to, a camera module. After receiving power from the earphone body 1, the camera module independently of the audio function of the earphone body 1 performs environmental image acquisition or video recording.

[0029] This embodiment aims to provide a modular headphone assembly that enables flexible expansion of functions through a removable extender 2, overcoming the shortcomings of fixed functions and difficulty in customization in the prior art.

[0030] In this embodiment, the headphone assembly is based on a modular design concept, retaining basic audio functions in the headphone body 1, while integrating extended functions (such as image acquisition) into a detachable extension unit 2. Through standardized mechanical connection structures and electrical interfaces, plug-and-play functionality is achieved between the extension unit 2 and the headphone body 1, with the headphone body 1 acting as the main power source for the extension unit 2.

[0031] As a typical example of extended functionality, the camera module works by acquiring environmental images or videos after receiving power from the headset body 1. This process is completely independent of the audio playback or call function of the headset body 1, ensuring the independent operation of the extended functionality and not interfering with the core audio experience.

[0032] On the other hand, the extension body 2 is also provided with a first communication module 25, which enables the extension body 2 to communicate wirelessly with external electronic devices.

[0033] In this embodiment, a first communication module 25 is provided on the extender 2 to enable the extender 2 to independently communicate wirelessly with external electronic devices, thereby more flexibly transmitting data generated by the functional module 21 or receiving control commands from external devices. The working principle is as follows: the first communication module 25 establishes a communication link with the external electronic device via radio waves. When the functional module 21 generates data (such as image data collected by the camera module), the extender 2 wirelessly transmits this data to external devices such as smartphones, tablets, and computers through the first communication module 25. Simultaneously, external devices can also send control commands to the extender 2 through the first communication module 25, such as controlling the camera module to start or stop recording.

[0034] Specifically, the first communication module 25 can be a Bluetooth module, a Wi-Fi module, an NFC module, or other wireless communication module. If the first communication module 25 is a Wi-Fi module, it can connect to a wireless local area network to achieve data transmission with higher bandwidth, such as real-time video streaming. The first communication module 25 typically includes radio frequency transceiver circuitry, baseband processing circuitry, and an antenna. The antenna can be integrated inside or outside the housing of the extension body 2.

[0035] On the other hand, a second communication module (not shown in the figure) can be set on the headphone body 1, and the extension body 2 can communicate wirelessly with external electronic devices by means of the second communication module.

[0036] This embodiment includes a second communication module on the earphone body 1, aiming to utilize the existing communication capabilities of the earphone body 1 to enable communication between the extender 2 and external electronic devices. The working principle is as follows: the extender 2 can communicate with the earphone body 1 via an electrical connection (including a data channel) between the first power interface 10 and the second power interface 20. When the extender 2 is working, it can send data to the earphone body 1, and then the second communication module wirelessly transmits the data.

[0037] The second communication module can be a Bluetooth module, a Wi-Fi module, or other wireless communication module. The second communication module is electrically connected to the controller inside the earphone body 1 for wireless communication with external electronic devices. The extender 2 can exchange data with the earphone body 1 through the electrical connection between the first power interface 10 and the second power interface 20. For example, in addition to power contact terminals, the first power interface 10 and the second power interface 20 may also include data contact terminals for transmitting data signals.

[0038] This embodiment provides a means for the extender 2 to communicate with external devices by utilizing the existing or enhanced communication capabilities of the earphone body 1. This is especially important when the extender 2 itself does not have a communication configuration. Even if the extender 2 has a communication configuration, communication via the second communication module of the earphone body 1 can serve as a backup solution, for example, by utilizing the stronger transmission power or more stable connection of the earphone body 1. This design makes the design of the extender 2 more flexible, allowing for the selection of whether to integrate communication functions or rely on the communication capabilities of the earphone body 1, depending on functional requirements.

[0039] On the other hand, the first power interface 10 and the second power interface 20 are magnetic contact interfaces 10a and 20a or USB interfaces 10b and 20b.

[0040] like Figure 1 and Figure 2 For magnetic contact interfaces 10a and 20a, an electrode plate A is provided on the outer shell of the earphone body 1. The electrode plate A has conductive contacts, and a magnet (such as a permanent magnet) is provided behind the electrode plate A. An electrode plate B that cooperates with the electrode plate A is provided on the extension body 2. The electrode plate B has corresponding conductive contacts.

[0041] When the electrode B of the extension body 2 is close to the electrode A, the electrode B and the electrode A are attracted together, forming an electrode connection to connect the power supply and data (when data needs to be uploaded to the function module 21 through the headphone body 1) channels.

[0042] like Figure 3 and Figure 4When using USB 10b or 20b interfaces, different specifications of USB 10b or 20b interfaces such as Micro USB and USB Type-C can be selected. Among them, USB Type-C supports reversible insertion, further improving ease of use. If high-speed data transmission is required, an interface supporting USB 3.0 or higher can be selected. After the connection steps are completed, the headphone body 1 can confirm that the expansion unit 2 has been connected and started supplying power by detecting the interface status (such as detecting current consumption or specific signals).

[0043] Specifically, magnetic contact interfaces 10a and 20a or USB interfaces 10b and 20b are used as the first power interface 10 and the second power interface 20. This aims to optimize the connection process between the extender 2 and the earphone body 1 by leveraging the convenience, reliability, and versatility of these interfaces. The working principle is as follows: When using magnetic contact interfaces 10a and 20a, the user simply needs to bring the extender 2 close to the interface area of ​​the earphone body 1; the magnetism will automatically guide the extender 2 to align and engage, allowing electrode B to physically contact and establish an electrical connection with electrode A. When using USB interfaces 10b and 20b, the user inserts the USB plug 20b of the extender 2 into the USB socket 10b of the earphone body 1, completing the connection through physical plugging and unplugging. Both methods achieve a removable connection and power transmission between the extender 2 and the earphone body 1.

[0044] When using magnetic contact interfaces 10a and 20a, the interface shape can be designed with guide grooves or protrusions to further assist alignment and prevent mis-insertion. The strength of the magnet can be adjusted according to requirements to balance adsorption stability and ease of separation. The number of contacts can be designed according to the types of power and data signals to be transmitted; for example, data contacts can be added to support communication protocols such as SPI, I2C, or UART.

[0045] On the other hand, such as Figure 1 The earphone body 1 is also equipped with a touch switch K, which is used to control the on / off state of the first power interface 10.

[0046] This embodiment features a touch switch K on the earphone body 1, designed to provide a convenient user interface for controlling functions related to the expansion unit 2, such as controlling the on / off state of the first power interface 10, thereby controlling the power supply and operation of the expansion unit 2. The working principle is as follows: the touch switch K generates an electrical signal by sensing the user's touch operation, and this signal is transmitted to the controller of the earphone body 1. The controller of the earphone body 1 interprets the intent of the touch operation according to preset logic or user configuration and executes corresponding control actions, such as controlling the power output of the first power interface 10. By controlling the on / off state of the first power interface 10, the expansion unit 2 can be turned on and off.

[0047] The touch switch K can be a capacitive or resistive touch panel, integrated on the outer surface of the earphone body 1 for convenient user touch operation. The touch switch K is electrically connected to the controller inside the earphone body 1.

[0048] On the other hand, the extension 2 also includes a processor 23, a memory 24 and a power supply circuit 22. The input terminal of the power supply circuit 22 is connected to the second power interface 20, and the output terminal of the power supply circuit 22 is connected to the functional module 21, the processor 23 and the memory 24.

[0049] In this embodiment, when the second power interface 20 is connected to the first power interface 10, the power signal provided by the earphone body 1 is processed by the power circuit 22 and converted into driving power corresponding to the processor 23, memory 24 and functional module 21 respectively.

[0050] Additionally, when data interaction is required between the extender 2 and the headphone body 1, the extender 2 also includes an interface conversion circuit 26, which is located between the second power interface 20 and the processor 23. The interface conversion circuit 26 performs format conversion on the data transmitted and received by the processor 23.

[0051] Furthermore, a detection circuit 27 may also be provided in the expansion body 2, which is connected between the second power interface 20 and the power circuit 22. The detection circuit 27 is used to detect whether the earphone body 1 connected to the expansion body 2 is compatible. If it is, the power circuit 22 outputs a power signal; if not, the power circuit 22 does not output a power signal.

[0052] Specifically, the detection circuit 27 can detect whether the devices are compatible by detecting the handshake signal between the first power interface 10 and the second power interface 20.

[0053] It should be noted that the specific circuit configurations of the detection circuit 27, the power supply circuit 22, and the interface conversion circuit 26 are all mature technologies in this field, and will not be described in detail here.

[0054] In summary, the above embodiments of this utility model disclose a multifunctional headphone assembly, including a headphone body 1 and an extension body 2. The headphone body 1 is provided with an output-type first power interface 10. The extension body 2 includes an input-type second power interface 20, a functional module 21, a power circuit 22, a processor 23, and a memory 24, etc. The first power interface 10 and the second power interface 20 are physically contacted and electrically connected in a removable manner, and the headphone body 1 provides power signals to the extension body 2 through the first power interface 10 and the second power interface 20. This headphone assembly utilizes the existing electrical energy of the headphone body 1, and can provide working power to the functional module 21 on the extension body 2 without an additional independent power supply, thereby solving the problem in the prior art that expanding functions requires an independent battery or complex connection method, greatly improving the functional expandability and ease of use of the headphone assembly, allowing users to flexibly add various functional modules 21 to the headphone according to their needs, such as cameras, additional sensors, or communication modules, etc., and the power supply is stable and reliable.

[0055] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
