Description

A bluetooth earphone with a replaceable interface

technical field

The utility model relates to a bluetooth earphone with a replaceable interface.

Background technique

Bluetooth headsets provide a safe and cordless way to make and receive calls and voice transmissions. The use of "Bluetooth" technology can effectively simplify the communication between communication terminal devices such as handheld computers, tablet computers, notebook computers and mobile phones, and can also successfully simplify the communication between the above devices and the Internet, so that these Data transmission between modern communication devices and the Internet has become faster and more efficient, broadening the way for wireless communication. Bluetooth headset is to apply Bluetooth technology to hands-free headsets, so that users can avoid annoying wires and talk easily in various ways. Using the Bluetooth headset, the mobile terminal or handheld device can be placed in the pocket or in the driving compartment of the car for hands-free calls. In addition, the user of the Bluetooth headset can move freely within the range that can maintain the connection, and can communicate with various devices, so it has been widely used.

However, the bluetooth earphones in the prior art also have at least the following problems: (1) users often forget to charge the bluetooth earphones in time, which limits their use. (2) Stereo Bluetooth headsets can listen to music, but consume too much power and are inconvenient to carry.

【Content of utility model】

The purpose of the utility model is to provide a bluetooth earphone with a replaceable interface in order to overcome the above-mentioned defects.

In order to solve the technical problems described above, the present invention takes the following technical solutions:

The utility model provides a bluetooth earphone with a replaceable interface, comprising a bluetooth earphone body, characterized in that, the bluetooth earphone body includes two bluetooth earphone units 10 and a connecting line 20, and the bluetooth earphone unit 10 passes through the connecting line 20 connection, the connection line 20 is provided with an audio conversion interface 30, the audio conversion interface 30 can be split into a conversion interface 31, a conversion joint 32, and one end of the audio conversion line 40 is provided with a conversion interface 41 and a conversion joint 42, so The conversion interface 41 is connected to the conversion joint 32, and the conversion joint 42 is connected to the conversion interface 31. The other end of the audio conversion line 40 is designed as an active audio interface 43 to connect with digital equipment.

Further, the active audio interface is an audio interface of a tablet computer, a notebook computer or a mobile phone.

Further, the bluetooth headset body can be used alone.

Further, when the audio conversion cable is connected to a digital device, the power of the Bluetooth headset body is turned off, and the entire Bluetooth headset device is used as a normal headset, and the battery power in the Bluetooth headset body is no longer consumed.

The utility model realizes the function of a wired earphone by setting a replacement audio conversion interface and an audio conversion line, and can still be used as an ordinary earphone when the Bluetooth earphone is out of power, and is compatible with most digital devices on the market, and is easy to carry.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in detail.

A bluetooth earphone with a replaceable interface, comprising a bluetooth earphone body, characterized in that, the bluetooth earphone body includes two bluetooth earphone units 10 and a connection line 20, the bluetooth earphone units 10 are connected by a connection line 20, the The connecting line 20 is provided with an audio conversion interface 30, and the audio conversion interface 30 can be divided into a conversion interface 31 and a conversion joint 32. One end of the audio conversion line 40 is provided with a conversion interface 41 and a conversion joint 42, and the conversion interface 41 and the conversion joint 42 The conversion joint 32 is connected, and the conversion joint 42 is connected with the conversion interface 31 . The other end of the audio conversion line 40 is designed as an active audio interface 43 to connect with digital equipment.

With reference to Figure 2, when the Bluetooth headset is turned off, the external audio signal is input to the speaker through J2 (MicroUSB); in the Bluetooth headset mode, the audio signals BL+/BL- and BR+/BR- are converted into single Terminal signal, output L, R signal to speaker output. At the same time, the audio signal is also output to the outside through MicroUSB.

The above descriptions are only embodiments of the present utility model, and are not intended to limit the scope of this patent. Any equivalent structure or equivalent process transformation made by the description of the present invention, or directly or indirectly used in other related technical fields, is the same. included in the scope of patent protection of the present invention.
