Description

TWS earphone

Technical Field

The utility model relates to a bluetooth wireless communication field, concretely relates to TWS earphone.

Background

The earphone is a pair of conversion units which receive the electric signals sent by the media player or receiver and convert the electric signals into audible sound waves by using a loudspeaker close to the ear. The headset is typically detachable from the media player and utilizes a plug connection. The earphone is originally used for telephone and radio, but with the prevalence of portable electronic devices, the earphone is mostly used for mobile phones, walkmans, radios, portable electronic games, audio players, and the like.

With the advancement of science and technology and the improvement of modern life requirements of people, bluetooth TWS (True Wireless Stereo) earphones are widely favored because they get rid of a connecting wire connecting from a player to an earphone body. The Bluetooth headset is particularly suitable for being worn during sports or other activities, can reduce the trouble caused by winding of the wire body, and is very convenient.

The existing Bluetooth TWS earphones in the market need to be connected with audio source equipment such as a mobile phone and a computer through Bluetooth and then transmit audio data, and then synchronous playing is carried out at the TWS earphone equipment end, and when no such audio source equipment is connected with the TWS earphones through Bluetooth, the TWS earphones cannot carry out audio playing.

In addition, the multi-purpose classic bluetooth of current TWS earphone carries out communication transmission, because classic bluetooth need continuously keep connected state, and scan the connection and transmit the time spent of data longer, therefore the consumption is higher, and is power consumptive too much in little volume, the TWS earphone that battery capacity is low for can't work for a long time.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a TWS earphone can make the application break away from the restriction that original needs the audio source device to connect to through BLE (Bluetooth Low Energy) Bluetooth mode improve the consumption.

The utility model discloses a following technical scheme realizes:

a TWS headset comprising a primary and a secondary headset, the primary and secondary headsets comprising:

the BLE module is used for communication between the main earphone and the auxiliary earphone, communication with external equipment and data processing;

the coder and decoder is connected with the BLE module and used for decoding and coding the transceiving data;

one of the primary and secondary earpieces further comprises:

and the memory is connected with the BLE module and is used for storing audio data.

Specifically, the memory is an embedded memory.

Specifically, the memory is an extrapolation memory.

The utility model provides a TWS earphone can independently play under the circumstances that no audio frequency source equipment connects the connection bluetooth, and has utilized bluetooth BLE module to carry out data transmission, and classic bluetooth transmission data is used in the contrast, can reduce the equipment consumption, extension earphone operating time.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a TWS earphone, including main earphone and vice earphone, main earphone and vice earphone all include: the BLE module is used for communication between the main earphone and the auxiliary earphone, communication with external equipment and data processing; the coder and decoder is connected with the BLE module and used for decoding and coding the transceiving data; wherein one of the main earphone and the sub-earphone further comprises: and the memory is connected with the BLE module and is used for storing audio data.

Above-mentioned BLE module includes radio frequency transceiver, baseband and agreement stack, and communication between main earphone and the auxiliary earphone, the communication with external equipment accomplish through this baseband and agreement stack, and the receiving and dispatching data passes through radio frequency transceiver to be accomplished, and in the bluetooth field, this content belongs to prior art, the utility model discloses do not specifically introduce here. And in the utility model discloses in, the reason that BLE module was chooseed for use to it lies in, TWS earphone is small usually, and the inside battery of large capacity that can't be placed, and work duration is an important index of TWS earphone, and BLE module helps reducing the consumption, realizes longer earphone operating time.

In the classic bluetooth, when the headset is connected, the bluetooth of the main headset and the bluetooth of the auxiliary headset are connected, which usually takes several hundred milliseconds, and the long connection is continuously maintained in the working state.

In BLE, it adopts variable connection time interval, and when needing transmission data, the BLE of main earphone and the BLE of auxiliary earphone accomplish once and connect, disconnect after data transmission accomplishes, waits the connection activation of next time, and this time interval can be as low as several milliseconds to accomplish data transmission in this interval, therefore, in longer time, BLE is in standby state, and its consumption is lower for the consumption of classic bluetooth.

Classic bluetooth and BLE's scanning mode, connected mode and data transmission mode are all different, and unable communication each other, and classic bluetooth only can be connected with classic bluetooth promptly, and BLE only can be connected with BLE, consequently the utility model discloses in, main earphone and vice earphone all adopt BLE to communicate.
