Description

Technical Field

[0001] The utility model belongs to the field of Bluetooth signal transmission and reception, and in particular relates to a Bluetooth transmitter. Background Art

[0002] A Bluetooth audio transmitter is used to convert a non-Bluetooth device into a device with Bluetooth function. For example, it can be connected to a TV without Bluetooth function to enable the TV to have Bluetooth function. Then, the Bluetooth audio transmitter can be connected to an active player with Bluetooth receiving function to play audio through the active player.

[0003] Currently, most audio transceivers on the market lack on-screen displays and rely on blind connection. This makes it difficult to distinguish the device models after connecting to multiple Bluetooth devices, as they all rely on LED lights for status indication. When a Bluetooth transmitter is connected to a user's headphones or speakers, it's unclear which headphone the transmitter is connected to, nor is there a way to see the current operating status of the device, as only the LED light indicates the device. This results in a poor user experience.

[0004] To address the aforementioned issues, a conventional Bluetooth transmitter features a display screen on its housing, allowing users to view the transmitter's current operating and connection status. However, operations are typically performed using buttons on the housing. Due to the limited number of buttons, a single button typically multiplexes multiple functions, distinguished by long press, short press, and double press. For example, a select control button includes three functions: previous track, volume up, and menu selection. Different press methods enable different functions: a long press for volume adjustment, a short press for the previous track, and a double press for menu selection, making operation inconvenient. Utility Model Content

[0005] The Bluetooth transmitter provided by the utility model aims to solve the technical problem of inconvenient operation of the Bluetooth transmitter in the prior art.

[0006] The utility model is implemented as follows: a Bluetooth transmitter includes a shell, a data interface arranged on the shell, a touch screen arranged on the shell and a circuit board arranged in the shell, an MCU processor and a Bluetooth chip are arranged on the circuit board, and the MCU processor is connected to the Bluetooth chip, the data interface and the touch screen respectively.

[0007] Furthermore, the data interface includes a 3.5mm headphone audio interface and a USB interface.

[0008] Furthermore, a microphone is provided on the housing, a voice recognition module connected to the MCU processor is provided on the circuit board, and the microphone is connected to the voice recognition module.

[0009] Furthermore, the Bluetooth transmitter further includes a power module disposed in the housing, and the power module is connected to the circuit board.

[0010] Furthermore, the power module adopts a lithium battery.

[0011] Furthermore, the housing is provided with a power on / off button connected to the circuit board.

[0012] Furthermore, the housing is also provided with a signal indicator light connected to the MCU processor.

[0013] Compared with the existing technology, the Bluetooth transmitter of the present invention adopts a touch display screen as the control interface, without the need for too many buttons. The user can directly operate the working mode, Bluetooth pairing, song switching, and volume adjustment of the Bluetooth transmitter through the touch screen, and can intuitively observe the results of the operation. The operation is convenient and the user experience is good. Furthermore, a voice recognition module is also adopted to recognize the user's voice and perform corresponding operations, further enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, 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. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. As used in this application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0019] In the specification of this application, for the convenience of description, the sizes of various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0020] See also Figure 1-Figure 2 In the first embodiment of the present invention, a Bluetooth transmitter is provided, which includes a housing 1, a touch screen 2 arranged on the housing 1, a data interface 3 arranged on the housing 1, a circuit board 4 arranged in the housing 1, a power module 5 arranged in the housing 1, and a power button 6 and a signal indicator light 7 arranged on the housing 1.

[0021] The data interface 3 includes a USB interface 31 and a 3.5mm headphone audio interface 32 respectively provided at both ends of the housing 1, which are used to connect to a device with a USB interface and a device with a 3.5mm headphone audio interface respectively.

[0022] An MCU processor 41 and a Bluetooth chip 42 are provided on the circuit board 4. The MCU processor 41 is connected to the Bluetooth chip 42, the data interface 3 and the touch screen 2 respectively. The power button 6 is connected to the circuit board 4, and is used to realize the power on and off of the Bluetooth transmitter and the opening and closing of the touch screen 2. The signal indicator light 7 is connected to the MCU processor 41, and is used to display the working mode of the Bluetooth transmitter. It should be noted that the working mode of the Bluetooth transmitter includes a transmitting mode and a receiving mode, which is selected by the working state of the Bluetooth chip 42, and the working state of the Bluetooth chip 42 can be controlled by the MCU processor 41. In the receiving mode, the Bluetooth transmitter is mainly used to receive Bluetooth signals and convert the signals into audio, video, picture and other data for playback or processing; in the transmitting mode, the Bluetooth transmitter is used to transmit audio, video, picture and other data to the paired device via Bluetooth wireless signals.

[0023] The touch screen 2 displays options and / or buttons that the user can operate. When the user operates the touch screen 2 and clicks a corresponding option or button, the user's click signal is transmitted to the MCU processor 41, and the MCU processor 41 performs the corresponding operation.
