Detailed Description

The technical solutions of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.

The TWS (True Wireless Stereo) headset is developed based on the bluetooth technology, and the left and right headsets of the TWS headset can be truly Wireless, so that a user can completely get rid of the constraint of a connecting line. The TWS earphone is internally provided with a Bluetooth chip, so that wireless connection can be realized with terminal equipment through a Bluetooth technology to play music. However, the TWS earphones in the related art are limited in applicable scenes, for example, when swimming or other underwater scenes, the 2.4GHz band of the bluetooth signal is severely attenuated underwater, which results in that audio transmission cannot be performed between the left and right earphones, and the TWS earphones cannot be applied to swimming or other underwater scenes.

In the related art, in order to implement underwater audio playing, a transmission module, such as an NFMI (Near Field Magnetic Induction) transmission module, is additionally added to a part of TWS headphones. The NFMI is a short-distance wireless technology, communication is achieved by coupling a magnetic field between devices, and the NFMI is low in underwater attenuation and can meet the requirement of short-distance audio transmission of underwater scenes. However, in order to realize the normal use of the TWS headset, the bluetooth module still needs to be arranged inside the headset, that is, the NFMI module and the bluetooth module are included inside the headset. The volume and the weight of the earphone are increased, the wearing experience of a user is influenced, and the NFMI is unstable compared with a Bluetooth connection signal, so that disconnection is easy to occur, and the data of two ears are not synchronous.

Based on the problems in the related art, the embodiments of the present disclosure provide a headset accessory and a headset kit including the same, which aim to implement audio transmission of an underwater scene of a TWS headset by using a detachable headset accessory.

First, it should be noted that "first wireless headset" and "second wireless headset" described in the following of the present disclosure may refer to TWS headsets, i.e., headset types without any cable connection between the first wireless headset and the second wireless headset. Generally, the first wireless headset and the second wireless headset may be left and right ear headsets, respectively, to create a stereo effect when playing audio. This is not repeated in the following of the present disclosure.

In some embodiments, a headset accessory in embodiments of the present disclosure includes: the connecting structure comprises a body, a first connecting structure, a second connecting structure and a connecting piece.

The body may be a body structure of a headset accessory, for example in some embodiments the body includes a first part and a second part for enabling a detachable fit with a first wireless headset and a second wireless headset. For example, in one example, the first and second components may be implemented as an earphone sleeve, such as silicone, plastic, etc. The earphone sleeve is provided with an assembly cavity matched with the earphone in shape, so that the assembly of the body and the earphone can be realized by sleeving the earphone sleeve in the assembly cavity, and the same principle is applied to the disassembly otherwise.

The first connecting structure, the second connecting structure and the connecting piece realize an electrical structure of the earphone accessory. In some embodiments, the first connection structure and the second connection structure may be fixedly disposed on the body, for example, the first connection structure and the second connection structure may be disposed inside the earphone sleeve, so that when the earphone sleeve is assembled with the earphone, the first connection structure may be connected with the first terminal of the first wireless earphone; the second connection structure may be connected with a second terminal of the second wireless headset.

In some embodiments, the first connection structure and the second connection structure may be implemented as metal components, and the electrical connection between the first connection structure and the first wireless headset and the electrical connection between the second connection structure and the second wireless headset may be: the metal part of the earphone accessory is in contact connection with the metal contact on the earphone, so that wired transmission of audio data can be realized through the contact connection of the metal part and the metal contact.

The present disclosure is described in detail below with respect to specific implementations of the above embodiments, and will not be described in detail here.

It can be appreciated that when the TWS headset is in an underwater scene such as swimming, the first wireless headset and the second wireless headset cannot communicate wirelessly due to underwater bluetooth signal attenuation. In the embodiment of the disclosure, the first wireless headset and the second wireless headset may be connected through a headset accessory, so that the first wireless headset and the second wireless headset may establish a communication connection through the headset accessory, and underwater audio data transmission is realized.

In the embodiment of the disclosure, the earphone accessory is detachably connected with the first wireless earphone and the second wireless earphone, so that the earphone accessory can be detached from the first wireless earphone and the second wireless earphone in daily scenes such as non-underwater environments, and the conventional use of the first wireless earphone and the second wireless earphone is realized.

Some embodiments of the disclosed headset accessory are shown in fig. 1 to 3, and the following detailed description of the structure of the disclosed headset accessory is made in conjunction with fig. 1 to 3.

As shown in fig. 1, in some embodiments, the headset accessory of the present disclosure includes a support portion 100, the support portion 100 may serve as a body of the headset accessory, and corresponding other structures and electrical elements may be disposed on the support portion 100.

In one example, the earphone accessory according to the embodiment of the present disclosure may be worn on the head or neck of a human body by using a memory metal for better supporting the head or neck of the human body, so that the user may wear the earphone accessory on the head or neck according to the size of the head or neck. Meanwhile, in order to keep comfortable wearing experience, the outer layer of the memory metal can be wrapped by silica gel, so that the memory metal is more compatible with human skin, and the wearing comfort is improved.

In this example, the first component and the second component are the earphone sleeve 300, and the earphone sleeve 300 may be made of a material with certain elasticity, such as silicon gel or plastic. As shown in fig. 2, the earphone sleeve 300 has a fitting cavity 310, and the shape of the fitting cavity 310 is adapted to the shape of the earphone 10, so that the earphone 10 can be fitted in the fitting cavity 310 through the elastic earphone sleeve 300, thereby realizing the fitting of the earphone 10 and the earphone accessory.

In some embodiments, the headset accessory of the present disclosure further comprises an adjustment structure to accommodate different head or neck sizes of users, since different users may have different head or neck circumferences and thus different positions of the headset.

With reference to fig. 1 and 3, the adjusting structure includes a sliding slot 410 and a sliding member 420 opened on the supporting portion. One end of the sliding member 420 is disposed in the sliding groove 410 and can slide in the sliding groove 410, and the other end of the sliding member 420 is fixedly disposed on the earphone sleeve 300. Therefore, when a user wears the earphone accessory, the position of the sliding piece 420 can be manually adjusted, so that the position of the earphone 10 is adjusted, and the wearing comfort and the experience are improved.

It is to be understood that the above embodiments are only described with respect to the connection structure of one of the earphones 10 and the earphone accessory, and the implementation manner of the earphone accessory on the other side is the same, which can be understood and fully implemented by those skilled in the art without any doubt with reference to the foregoing description, and the disclosure is not repeated herein.

After the above description of the main structure of the headset accessory, the following description will be given of the electrical structure and the operation principle of the headset accessory based on the above structure.

The first connection structure and the second connection structure may be built inside the earphone sleeve 300, so that after the earphone 10 is assembled with the earphone sleeve, on one hand, the assembly cavity 310 of the earphone sleeve 300 may be sealed, and the first connection structure and the second connection structure are avoided; on the other hand, the first connecting structure and the second connecting structure are electrically connected with the earphone 10, and the signal transmission performance is improved.

As shown in fig. 1, the connection member 500 may be a connection wire, which may be any cable suitable for electrical connection, such as a coaxial cable, a twisted pair cable, an FPC (Flexible Printed Circuit), and the like.

In some embodiments, the connection element 500 may be embedded inside the support portion 100, so that when the user wears the earphone accessory, the connection element 500 is prevented from shaking along with the movement of the user, and the wearing experience is improved. Of course, it will be understood by those skilled in the art that the connection member 500 may be disposed outside the support portion 100, and the present disclosure is not limited thereto.

It should be noted that in other embodiments of the present disclosure, the supporting portion 100 may not be provided in the earphone accessory, that is, the first component and the second component may be directly connected to each other through the connecting member 500. For example, in the case that the connector 500 is a cable such as a coaxial cable or a twisted pair cable, the left and right earphone sleeves may be structurally connected by the cable. In these embodiments, the flexible cable is more convenient for the user to carry than the support portion 100 to accommodate the earphone accessory.

In this embodiment, the TWS headset may implement local play, that is, the TWS headset does not need to be connected to the mobile terminal, but one of the first wireless headset and the second wireless headset is used as a primary headset, and the other is used as a secondary headset. When the audio is played, the main earphone can send the audio data through the Bluetooth antenna of the main earphone, so that the auxiliary earphone can receive the audio data sent by the main earphone through the Bluetooth antenna of the auxiliary earphone, and the stereo audio playing of double ears is realized. However, in underwater scenes such as swimming, the direct communication requirement of the audio signals between the main earphone and the auxiliary earphone cannot be met obviously because the underwater bluetooth signal attenuation is limited and the transmission distance of the bluetooth signal is only a few centimeters. Therefore, the present embodiment is just to realize the communication requirement of the first wireless headset and the second wireless headset through the headset accessory.

Fig. 4 illustrates some embodiments of the first wireless headset and/or the second wireless headset according to the present disclosure, and the structure and principle of the TWS headset will be described with reference to fig. 4.

As shown in fig. 4, the headset 10 may be a first wireless headset and/or a second wireless headset, which is not limited by this disclosure.

The present disclosure is not so limited.

The wireless communication unit 14 includes a communication antenna and a radio frequency circuit electrically connected to the communication antenna, and the radio frequency circuit feeds the communication antenna to implement the transceiving of the audio data. In some embodiments, the communication antenna may be arranged inside the headset 10, which may be embodied as, for example, a FPC antenna or a microstrip antenna, etc.

In some embodiments, the wireless communication unit 14 of the headset 10 is a bluetooth module, such that the bluetooth antenna is fed by radio frequency circuitry such that the bluetooth antenna can radiate or receive signals having a center frequency at 2.4 GHz.

Of course, it is understood that the TWS headset may also include other electrical structures therein, such as batteries, sensors, etc., as will be understood and fully implemented by those skilled in the art with reference to the relevant art, and the present disclosure is not repeated herein.

The TWS headset shown in fig. 4 may be used in non-underwater scenarios. And when the earphone is used in a non-underwater scene, the earphone can be connected with the terminal equipment for playing, and local playing can also be realized. Specifically, in one example, the TWS headset may receive audio data sent by, for example, a smartphone through the wireless communication unit 14, thereby implementing audio playback after processing by the second controller 11. In another example, the left and right earphones may be divided into a main earphone and a sub earphone, wherein the second controller 11 of the main earphone reads audio data from the second memory 12, processes the audio data and then transmits the audio data through the wireless communication unit 14, and the sub earphone receives an audio signal through the wireless communication unit 14 of the sub earphone and processes the audio signal to realize audio playing.
