Description

Technical Field

[0001] The present application relates to the field of audio technology, and in particular to a wireless headset, a headphone bracket and a headset assembly. Background Art

[0002] With the progress of society and the improvement of people's living standards, headphones have become an indispensable daily necessity. Traditional wired headphones are connected to smart devices (such as smartphones, laptops, tablets, etc.) through wires, which restricts the wearer's movements, especially in sports. At the same time, the entanglement and pulling of the headphone wires, as well as the stethoscope effect, will affect the user experience. Ordinary Bluetooth headphones cancel the connection between the headphones and smart devices, but there is still a connection between the left and right ears. True wireless stereo headphones came into being.

[0003] At present, headphones have a good sound field and are comfortable to wear. However, there are audio cables and power cables between the two ears of headphones, which are easy to break and are not conducive to folding and storing the headphones. Wireless headphones are not as good as headphones in terms of sound field and wearing comfort. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a wireless headset, a headphone stand and a headphone assembly, so as to improve the sound field of the wireless headset and enhance the wearing comfort of the wireless headset.

[0006] The present application sets audio output contacts on the shell of the wireless headset and connects the audio output contacts to the audio output digital-to-analog conversion interface of the processing chip, thereby outputting the audio data of the wireless headset through an external device, so that the wireless headset can cooperate with the headphone bracket, thereby improving the sound field and enhancing wearing comfort.

[0007] In one embodiment, an antenna contact is further disposed on the outer surface of the shell, and the processing chip further includes an antenna interface, and the antenna interface is electrically connected to the antenna contact.

[0008] In the present application, by setting antenna contacts on the outer surface of the shell, the antenna of the external device can be connected through the antenna contacts. The wireless headphones are relatively small and the space is limited, so the antenna size is often relatively small. The external antenna can be connected to the headphone bracket, and the antenna size can be increased, thereby improving the wireless communication quality of the wireless headphones.

[0009] In one embodiment, a microphone contact is further provided on the outer surface of the housing, and the processing chip further includes an audio input analog-to-digital conversion interface, and the microphone contact is electrically connected to the audio input analog-to-digital conversion interface.

[0010] In the present application, by providing a microphone contact on the outer surface of the housing, an external microphone can be connected through the microphone contact.

[0011] In one embodiment, a charging contact is further provided on the outer surface of the housing, the wireless earphone further includes a rechargeable battery, and the processing chip further includes a power supply interface. The rechargeable battery is housed in the housing space and is electrically connected to the power supply interface and the charging contact respectively. Through the charging contact, the rechargeable power supply in the headphone holder can directly charge the wireless earphone without taking the wireless earphone out of the headphone holder. Thus, it is convenient for the user to use.

[0012] The embodiment of the present application further provides a headphone holder, including: a connecting member; a first ear cup and a second ear cup located at opposite ends of the connecting member. The first ear cup and the second ear cup are respectively provided with a receiving groove for receiving the aforementioned wireless earphone. Audio connection contacts are provided on the groove walls of the receiving grooves for correspondingly abutting against the audio output contacts; and a first speaker and a second speaker are respectively fixed on the first ear cup and the second ear cup and are electrically connected to the corresponding audio connection contacts respectively.

[0013] For the headphone holder provided by the present application, by providing the receiving groove, it is convenient to receive the wireless earphone, and by providing audio connection contacts electrically connected to the speaker on the groove wall of the receiving groove, when the wireless earphone is received in the receiving groove, the audio data of the wireless earphone can be played through the speaker on the headphone holder by connecting the audio connection contacts with the audio output contacts, so as to realize the cooperation between the headphone holder and the wireless earphone, improve the sound field of the wireless earphone and enhance the wearing comfort of the wireless earphone.

[0014] In one embodiment, the opening directions of the receiving grooves on the first ear cup and the second ear cup are opposite to each other.

[0015] In the present application, by setting the opening directions of the receiving grooves on different ear cups to be opposite to each other, after the wireless earphone is inserted into the receiving groove, the wireless connection of the wireless earphone will not be affected by the shielding of the ear cup.

[0016] In one embodiment, the headphone stand further includes a stand antenna. The stand antennas are respectively disposed on the first earcup and the second earcup. Stand antenna contacts are further disposed on the wall of the receiving groove. The stand antennas are respectively electrically connected to the corresponding stand antenna contacts.

[0017] In this application, by providing a stand antenna on the headphone stand, after the wireless earphone is inserted into the head-mounted wireless earphone, it can be connected to the stand antenna through the antenna contact. Thus, the wireless connection of the wireless earphone is strengthened through the stand antenna.

[0018] In one embodiment, the headphone stand further includes a stand microphone. The stand microphones are respectively disposed on the first earcup and the second earcup. Stand microphone contacts are further respectively disposed on the wall of the receiving groove. The stand microphones are respectively electrically connected to the corresponding stand microphone contacts.

[0019] In this application, by providing a stand microphone on the headphone stand, after the wireless earphone is inserted into the headphone stand, the sound pickup effect of the wireless earphone will not be affected by the obstruction of the headphone stand.

[0020] In one embodiment, the headphone stand further includes a rechargeable power source. The rechargeable power sources are respectively received in the first earcup and the second earcup, and are respectively electrically connected to the first speaker and the second speaker.

[0021] An embodiment of this application further provides a headphone assembly, including the aforementioned wireless earphone and the aforementioned headphone stand.

[0022] Through the cooperation of the wireless earphone and the headphone stand in this application, the sound field of the wireless earphone can be improved, and the wearing comfort of the wireless earphone can be enhanced.

Detailed implementation manners

[0029] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] Please refer to Figure 1 , an embodiment of the present application provides a wireless earphone 10. The wireless earphone 10 can be wirelessly connected to electronic devices such as audio players, mobile phones, computers, TVs, etc., receive the audio data sent by the electronic devices, and play the audio data.

[0031] According to different usage methods, the wireless earphone 10 can be an in-ear earphone, a semi-in-ear earphone, an open earphone, an earplug earphone, an ear-hook earphone, etc. In this embodiment, the wireless earphone 10 is an ear-hook earphone. According to different functions, the wireless earphone 10 can be an active noise-canceling earphone (the noise-canceling methods include feedforward noise cancellation and / or feedback noise cancellation), a stereo earphone, etc. In this embodiment, the wireless earphone 10 is an active noise-canceling earphone, and the noise-canceling methods include feedforward noise cancellation and feedback noise cancellation.

[0032] In this embodiment, the wireless earphone 10 includes a left wireless earphone 11 and a right wireless earphone 13. The left wireless earphone 11 and the right wireless earphone 13 are independently arranged. Compared with the existing over-ear headphones, the wireless earphone 10 of the present application omits the audio cable connected between the left and right wireless earphones, avoiding the influence of the audio cable on noise cancellation. Both the left and right wireless earphones can be used separately. It can be understood that in other embodiments, the wireless earphone 10 can only include the left wireless earphone 11 or the right wireless earphone 13.

[0033] In this embodiment, the left and right wireless earphones have a mirror structure. Hereinafter, the left wireless earphone 11 will be taken as an example to introduce the earphone structure.

[0034] Please refer to Figure 1 and Figure 2 , the left wireless earphone 11 includes a housing 110. The housing 110 has a receiving space inside for receiving the electronic components of the left wireless earphone 11. An audio output contact 111 is provided on the outer surface of the housing 110.

[0035] The left wireless earphone 11 further includes a processing chip 115. The processing chip 115 is disposed in the receiving space of the housing 110. The processing chip 115 has an audio output digital-to-analog conversion interface 116. The audio output digital-to-analog conversion interface 116 is electrically connected to the audio output contact 111. Thus, it is possible to transmit the audio data received by the left wireless earphone 11 from the electronic device to an external device electrically connected to the audio output contact 111 through the audio output digital-to-analog conversion interface 116 and the audio output contact 111 for playback. In this embodiment, the audio output contact 111 may be located on the side of the outer surface of the housing 110 in contact with the human ear canal when the left wireless earphone 11 is worn.

[0036] In this embodiment, an antenna contact 112 is further provided on the outer surface of the housing 110. Correspondingly, the processing chip 115 further includes an antenna interface 117. The antenna interface 117 is electrically connected to the antenna contact 112. Thus, it is possible to connect the antenna of an external device through the antenna interface 117 and the antenna contact 112. It can be understood that since the left wireless earphone 11 is relatively small in size and the receiving space inside the housing 110 is limited, the antenna size of the left wireless earphone 11 itself is small. Connecting the antenna of an external device through the antenna interface 117 and the antenna contact 112 can improve the wireless communication quality of the left wireless earphone 11. In this embodiment, the antenna contact 112 is disposed adjacent to the audio output contact 111.

[0037] It can be understood that in order to avoid shielding, the antenna of an external device is usually disposed on the outer side of the top of the external device. Therefore, in order to facilitate connecting the antenna contact 112 to the antenna of the external device, the antenna contact 112 may also be disposed on the outer surface of the top of the housing when the left wireless earphone 11 is worn.

[0038] In this embodiment, a microphone contact 113 is further provided on the outer surface of the housing 110. Correspondingly, the processing chip 115 further includes an audio input analog-to-digital conversion interface 118. The audio input analog-to-digital conversion interface 118 is electrically connected to the microphone contact 113. Thus, an external device's microphone can be connected through the audio input analog-to-digital conversion interface 118 and the microphone contact 113, thereby improving the sound collection effect of the left wireless earphone 11. In this embodiment, the microphone contact 113 can be arranged adjacent to the audio output contact 111 and the antenna contact 112. It can be understood that, to improve the sound collection effect, the external device's microphone is usually arranged at a position close to the sound source. For example, it is arranged at the end of the external device. Therefore, to facilitate the connection between the microphone contact 113 and the external device's microphone, the microphone contact 113 can also be arranged on the outer surface of the bottom end of the housing 110 when the wireless earphone 11 is worn. In this way, the distance between the microphone contact 113 and the external device's microphone can also be shortened.

[0039] In this embodiment, a charging contact 114 is further provided on the outer surface of the housing 110. The left wireless earphone 11 further includes a rechargeable battery 120. The processing chip 115 further includes a power supply interface 119. The rechargeable battery 120 is housed in the accommodation space of the housing 110 and is electrically connected to the power supply interface 119 and the charging contact 114 respectively. Thus, the rechargeable battery 120 can supply power to the processing chip 115 through the power supply interface 119, and at the same time, it can be connected to an external device through the charging contact 114 to be charged using the external device's power source. In this embodiment, the charging contact 114 is located on the outer surface of the bottom end of the housing when the left wireless earphone 11 is worn.

[0040] In this embodiment, since the left wireless earphone 11 and the right wireless earphone 13 have a mirror structure, correspondingly, the right wireless earphone 13 includes a housing, an audio output contact, a processing chip, an audio output digital-to-analog conversion interface, an antenna contact, an antenna interface, a microphone contact, an audio input analog-to-digital conversion interface, a charging contact, a rechargeable battery, and a power supply interface. The specific settings and connection relationships of these components can refer to the content of the aforementioned left wireless earphone 13 and will not be elaborated here.

[0041] For the wireless earphone provided by this application, by providing an audio output contact on the housing of the wireless earphone and connecting the audio output contact to the audio output digital-to-analog conversion interface of the processing chip, thus, it can be realized to output the audio data of the wireless earphone through an external device, so as to facilitate the cooperation between the wireless earphone and the external device, thereby improving the sound field and enhancing the wearing comfort.

[0042] In the present invention, the wireless earphone can be used as an ordinary wireless earphone to wirelessly connect with a smart device and transmit and receive audio data.

[0043] Based on the same inventive concept, please refer to Figure 3, an embodiment of the present application further provides a headphone stand 20.

[0044] The headphone stand 20 includes a connecting member 22. The connecting member 22 may have a telescopic structure or an elastic structure so as to store and place the headphone stand 20 when the headphone stand 20 is not in use.

[0045] In this embodiment, the headphone stand 20 further includes a first earcup 21 and a second earcup 23 located at opposite ends of the connecting member 22. The first earcup 21 and the second earcup 23 have a mirror image structure. The first earcup 21 and the second earcup 23 are respectively provided with receiving grooves (not shown in the figure) for receiving and fixing the wireless earphones 10 of the foregoing embodiment. That is, the receiving grooves of the first earcup 21 and the second earcup 23 are respectively used for receiving and fixing the left wireless earphone 11 and the right wireless earphone 13 in the foregoing embodiment. Audio connection contacts are provided on the groove walls of the receiving grooves of the first earcup 21 and the groove walls of the receiving grooves of the second earcup 23. The audio connection contacts are used to correspondingly abut against the audio output contacts of the corresponding wireless earphones in the receiving grooves.

[0046] In this embodiment, the headphone stand 20 further includes a first speaker and a second speaker. The first speaker and the second speaker are respectively fixed on the first earcup 21 and the second earcup 23 and are respectively electrically connected to the corresponding audio connection contacts. The sound output directions of the first speaker and the second speaker are oppositely arranged.

[0047] The headphone stand provided by the present application is provided with a receiving groove, which is convenient for receiving wireless earphones. Audio connection contacts electrically connected to the speakers are provided on the groove walls of the receiving groove, so that when the wireless earphones are received through the receiving groove, the audio data of the wireless earphones can be played through the speakers on the headphone stand by connecting the audio connection contacts with the audio output contacts, thereby realizing the cooperation between the headphone stand and the wireless earphones, improving the sound field of the wireless earphones and enhancing the wearing comfort of the wireless earphones.

[0048] In this embodiment, the openings of the receiving grooves on the first earcup 21 and the receiving grooves on the second earcup 23 face away from each other. Thus, after the left and right wireless earphones are respectively inserted into the receiving grooves of the first earcup and the second earcup, the earcups will not block the corresponding wireless earphones, thereby avoiding the influence of the blockage on the wireless connection between the wireless earphones and the electronic device and avoiding the influence of the blockage on the sound collection of the microphones of the wireless earphones.

[0049] In this embodiment, the headphone bracket 20 also includes a bracket antenna. The bracket antenna is respectively arranged on the first earmuff 21 and the second earmuff 23. Correspondingly, the groove wall of the receiving groove of the first earmuff 21 and the groove wall of the receiving groove of the second earmuff 23 are also respectively provided with bracket antenna contacts. The bracket antenna is electrically connected to the corresponding bracket antenna contacts. After the left and right wireless earphones are loaded into the corresponding receiving grooves, the antenna contacts of the wireless earphones are correspondingly abutted with the bracket antenna contacts on the groove walls of the corresponding receiving grooves, so that the wireless earphones 10 can enhance the wireless connection between it and the electronic device, and enhance the wireless connection between the left and right wireless earphones by means of the bracket antenna on the headphone bracket 20. Optionally, the bracket antenna is respectively arranged on the opposite sides of the first earmuff 21 and the second earmuff 23 to prevent the earmuffs from blocking the bracket antenna and affecting the effect of the wireless connection. It can be understood that in other embodiments, the bracket antenna on the first earmuff 21 and the bracket antenna on the second earmuff 23 can extend toward each other along the connecting piece 22 and be connected. After the left and right wireless earphones are respectively installed in the receiving grooves of the first earmuff 21 and the second earmuff 23, the antenna contacts of the left wireless earphone 11 and the antenna contacts of the right wireless earphone respectively abut against the bracket antenna contacts on the groove walls of the corresponding receiving grooves, and share the bracket antenna.

[0050] In this embodiment, the headphone bracket 20 also includes a bracket microphone. The bracket microphone is respectively arranged on the first earmuff 21 and the second earmuff 23. The bracket microphone is located at the end of the corresponding earmuff away from the connecting piece to improve the sound reception effect of the bracket microphone to a certain extent. Bracket microphone contacts are also respectively arranged on the groove wall of the receiving groove. The bracket microphone is electrically connected to the corresponding bracket microphone contacts. After the left and right wireless earphones are loaded into the receiving groove, the microphone contacts of the left wireless earphone 11 and the microphone contacts of the right wireless earphone 13 are respectively abutted against the bracket microphone contacts on the groove wall of the corresponding receiving groove, so that the wireless earphone 10 can use the bracket microphone on the headphone bracket 20 to receive sound, so as to improve the sound reception effect. Compared with the microphone of the wireless earphone itself, which is easily blocked by the earmuff, the placement position of the bracket microphone is also more flexible, and has a better sound reception effect.

[0051] In this embodiment, the head-mounted headphone holder 20 further includes a rechargeable power source. The rechargeable power sources are respectively housed in the first earcup 21 and the second earcup 23, and are respectively electrically connected to the first speaker and the second speaker for supplying power to the corresponding speakers. In this embodiment, power supply contacts may be respectively provided on the walls of the receiving grooves. The rechargeable power sources located in the first earcup 21 and the second earcup 23 are respectively connected to the corresponding power supply contacts. After the left wireless earphone 11 and the right wireless earphone 13 are respectively inserted into the receiving grooves of the first earcup 21 and the second earcup 23, the charging contacts of the left wireless earphone 11 and the charging contacts of the right wireless earphone 13 respectively abut against the power supply contacts on the walls of the corresponding receiving grooves, so as to realize charging the rechargeable battery 120 of the wireless earphone 10 through the rechargeable power source of the head-mounted headphone holder 20.

[0052] In other embodiments, the head-mounted headphone holder 20 may further include a holder charging contact. The holder charging contact is electrically connected to the rechargeable power source and the power supply contacts on the wall of the receiving groove. The holder charging contact is used to connect to an external power source to charge the rechargeable power source of the head-mounted headphone holder 20, and to charge the rechargeable battery 120 of the wireless earphone 10 after the charging contacts of the left wireless earphone 11 and the right wireless earphone 13 are respectively inserted into the receiving grooves of the first earcup 21 and the second earcup 23 and the charging contacts of the left wireless earphone 11 and the charging contacts of the right wireless earphone 13 respectively abut against the power supply contacts on the walls of the corresponding receiving grooves.
