Description

Wireless Bluetooth earphone for live broadcast

Technical Field

The utility model relates to a wireless bluetooth headset, especially a wireless bluetooth headset who possesses live transmission function.

Background

Most of the existing wireless Bluetooth headset products are used by digital products such as mobile phones, computers, tablets and the like, and the devices generally have Bluetooth functions, so that the commonly used Bluetooth headsets in the general market can be normally used; some devices such as live broadcast sound cards, televisions, radios, electronic musical instruments and the like do not have the Bluetooth transmitting function. Usually, the earphone can only be connected with a wired earphone for use or played through an external loudspeaker, so that requirements on use environment and time period are met, and experience is very inconvenient. Especially the increase of present live sound card frequency of use, the anchor usually all adopts wired earphone to connect sound card listening accompaniment and music at present, is very inconvenient like this when carrying out the live of talent and skill show, and the space that can move about is also very restricted, can take away equipment and break even when moving suddenly. When a person watches television in quiet at night, the live broadcast wireless Bluetooth headset can be used for avoiding disturbing family rest and other application occasions.

PCBA is short for Printed Circuit Board + Assembly, that is PCBA is loaded on PCB by SMT and then is processed by DIP.

The invention belongs to the technical field of sound pick-up devices, and particularly relates to a sound effect sound pick-up device of a live broadcast Bluetooth drum machine, which aims at the problems that the traditional acoustic guitar sound pick-up device has single function and only has sound pick-up function. The multifunctional sound pickup device is simple in structure, the functions of the sound pickup are increased, the sound pickup device can be used in a diversified mode, and the experience effect is improved.

However, the inventor of the present invention finds that the above technical solution has two disadvantages: first, this live bluetooth adapter is only fixed on an audio equipment, and what audio input adopted moreover is the microphone input, need convert through the chip, is easily by the interference of ambient sound.

Secondly, although the utility model can collect sound sources of musical instruments such as electric guitars, the audio signals of other audio playing devices cannot be input and transmitted, and no matched Bluetooth receiving product is provided. Customer usage is not very comprehensive.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a live broadcast wireless Bluetooth earphone, which supports a wireless transmission of audio data signals to a Bluetooth earphone matched with a live broadcast sound card and the like by using an audio interface such as 3.5MM and the like as an audio input end and connecting the audio equipment such as the live broadcast sound card and a Bluetooth transmitting device; when the transmitting device is powered on and the receiving device is powered on, the two devices are automatically matched and connected, and the working state is displayed through the LED indicating lamp.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

Furthermore, the audio processing Bluetooth transmitting unit comprises a Bluetooth transmitting PCBA board card, a high-frequency transmitting circuit, an LED indicating lamp and an antenna.

Furthermore, the audio connection unit comprises a tail card, an audio connection line, audio head plastic and an audio plug, wherein one end of the audio connection unit is used for being connected with an audio input port of the Bluetooth transmission PCBA board card, and the other end of the audio connection unit is used for being connected with an output port of audio output equipment.

Preferably, the power supply interface is a USB interface.

Preferably, the power supply interface is a TYPE-C interface.

The working principle of the utility model is as follows:

the Bluetooth transmitting device is inserted into a power adapter and other power supply equipment, and a 3.5MM audio interface is connected with audio equipment such as a live broadcast sound card; the transmitting device is automatically started and automatically searches for the matched Bluetooth receiving device, the LED indicating lamp is in a flashing state in the matching process, and the LED lamp is normally on after the matching is successful. At the moment, the sound transmission of the equipment such as the live sound card and the Bluetooth equipment such as the Bluetooth earphone can be carried out.

The utility model discloses technical scheme's beneficial technological effect does:

first, the utility model discloses directly increase the audio transmission mode with bluetooth headset by original equipment that has bluetooth function (such as cell-phone, panel computer etc.) and extend to not have bluetooth function's equipment (such as TV, radio, electronic musical instrument etc.) can all experience sound wireless transmission's convenience through this application.

Secondly, the utility model can be used for the sound transmission of the live sound card and can replace the existing wired connection; the method and the device have the advantages of providing good convenience and bringing better experience effect to users.
