Description

Bluetooth headsets and Bluetooth devices that can be connected to external audio devices

technical field

The invention relates to a bluetooth headset and a bluetooth device, in particular to a bluetooth headset and a bluetooth device which can be connected with an external audio equipment.

Background technique

With the continuous advancement of science and technology, all electronic products are developing towards the trend of lightweight and miniaturization. People can use miniaturized electronic products, such as radios or walkmans, anytime and anywhere. In addition, due to the increasing popularity of personal digital products, such as common MP3 players, mobile phones, personal digital assistants (Personal Digital Assistant, PDA) or notebook computers, etc., are indispensable in daily life. In addition, mobile phones that combine radio and MP3 functions have also appeared.

Regardless of the above-mentioned electronic products, in order to allow users to listen to the audio information provided by the electronic products without disturbing others, earphones have become a necessary accessory for the electronic products. In addition, the earphone also provides better sound transmission for the listener, so that the listener can clearly hear and understand the sound content, unlike the unclear situation caused by the sound transmission in the air, especially when the user is moving, For example, it will not be affected by sports, driving, intense activities or noisy environments.

In terms of the use of mobile phones, in order to reduce the damage that electromagnetic waves may cause to the human body and allow users to enjoy the convenience brought by mobile phones when their hands are empty, a Bluetooth headset has been developed in recent years. Bluetooth headsets use a radio specification called "Bluetooth". Its main features are non-directional, capable of processing voice and data, and can be connected to multiple devices at the same time, low power, power saving, easy to use, and no transmission. The angle is limited and can penetrate walls, so it has become the first choice for wireless earphones with mobile phones.

However, most of the bluetooth headsets currently on the market can only be used to answer calls from mobile phones. Therefore, when users hang the bluetooth headset on their ears, they can no longer receive music, radio or other sound information, which is very inconvenient to use . Of course, some expensive mobile phones also have the function of MP3 player or FM radio, which can transmit the sound signal to the Bluetooth headset through Bluetooth technology. However, the cost of this device for transmitting stereo audio information from the mobile phone to the Bluetooth headset is extremely high, because both the mobile phone and the Bluetooth headset need to use a stereo Bluetooth transceiver. A monotone Bluetooth transceiver used in telephony.

Furthermore, only the MP3 provided by the mobile phone has a limited selection of tracks, and if the user wants to change a large number of tracks, enjoy movies or use other audio devices, the Bluetooth headset must still be taken off and replaced with the stereo earphone of the audio device. In this way, when the user receives the sound signal of the audio device through the stereo earphone, even if there is an incoming ringtone or vibration, the user is hardly aware of it. Therefore, the design of the bluetooth earphones currently available on the market cannot allow the user to enjoy the sound entertainment provided by other audio devices while waiting for an incoming call.

It can be seen that the above-mentioned existing bluetooth earphones and bluetooth devices obviously still have inconveniences and defects in structure and use, and need to be further improved urgently. In order to solve the problems existing in Bluetooth earphones and Bluetooth devices, related manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and general products do not have a suitable structure to solve the above problems. This is obviously a problem that relevant industry players are eager to solve.

In view of the defects existing in the above-mentioned existing bluetooth earphones and bluetooth devices, the inventor, based on years of rich practical experience and professional knowledge engaged in the design and manufacture of such products, and in conjunction with the application of academic theories, actively researches and innovates in order to create a new The bluetooth earphone and the bluetooth device that can be connected with the audio device can improve the general existing bluetooth earphone and the bluetooth device to make it more practical.
