This application is based upon and claims priority to Chinese Patent Application No. 202211354532.6, filed on Nov. 1, 2022, the entire contents of which are incorporated herein by reference.
The present invention relates to the technical field of earphones, particularly an open-ear Bluetooth® earphone.
Earphones are a pair of conversion units that accept electric signals from a media player or a receiver and convert them into an audible sound wave using a speaker close to the ears. Earphones include in-ear earphones. In-ear earphones provide a sense of pressure to the ear canal of the wearer, thus making the wearer's ears uncomfortable. In addition, in-ear earphones isolate the ear from the sound of the external environment, which is not conducive to the wearer's listening to the sound of the external environment when wearing the in-ear earphones. For this reason, semi-in-ear earphones are developed, and the semi-in-ear earphones reduce the pressure of the in-ear earphones on the ear canal. However, since the main body of the semi-in-ear earphones is made of hard plastic material, after the semi-in-ear earphones are worn for a long time, the hard plastic material plugged into the cavum concha will cause the wearer's ear to feel pain and other discomforts. Moreover, semi-in-ear earphones have poor stability that easily falls off when worn. Later, bone-conduction earphones are developed. Since the sound transmitted by the bone-conduction earphones is produced by the vibration of vibrators, sound quality suffers from a large transmission loss when the bone of the wearer receives the sound transmitted by vibration, which leads to poor sound quality received by the wearer wearing the bone-conduction earphones, and thus the wearer has a poor experience. Then, open-ear Bluetooth® earphones are developed.
The prior patent with a publication number of CN214429681U discloses a hanging and clamping ear-type open-ear earphone, which has the following advantages: A hanging and clamping ear-type structure is sleeved and hung on the upper side and the back side of the ear. An installation structure is connected to the upper end of the hanging and clamping ear-type structure and extends to the front side of the ear hole, and the sound outlet port faces the ear hole. In this way, there is no need to plug the earphones into the ear hole so the wearer can hear the sound of the surrounding environment, will not experience discomfort after wearing it for a long time, and will not cause damage to the hearing. However, since the size and outer contour of the wearer's ears vary from person to person, after different wearers wear the hanging and clamping ear-type open-ear earphones through the hanging and clamping ear-type structure, the sound outlet port of the installation structure may no longer face the ear hole, which makes it difficult for some wearers to receive the best sound, thus reducing the user experience of the wearers.
Moreover, as shown in the non-patent document (“JBL Nearbuds”, namely an open-ear Bluetooth® earphone: https://speaker.yesky.com/56/726008556.shtml), the open-ear Bluetooth® earphone is also hung on the ear by using the outer contour of the wearer's ears. Since the size and outer contour of the wearer's ears vary from person to person, when different wearers hang the open-ear Bluetooth® earphone on the ear through the outer contour of the ear, the distances between the audio source of the earphone and the ear canals of different wearers are different, so it cannot be adapted to different wearers. As a result, the sound emitted from the audio source of the earphone cannot be transmitted to the ear canal in the shortest distance, and the wearer's ears cannot receive the best sound, thus reducing the user experience of the wearer.
Given the above, an objective of the present invention is to provide an open-ear Bluetooth® earphone, which solves the problem that the audio source and the ear canal cannot be accurately located when the prior open-ear Bluetooth® earphone is worn and ensures that the audio source is tightly adheres to the ear canal and corresponds to the ear canal so that the sound emitted from the audio source is optimally transmitted into the ear canal to improve the user experience.
The objective of the present invention is realized through the technical solutions as follows:
An open-ear Bluetooth® earphone includes an earphone body and a support frame configured to be plugged into a cavum concha of a wearer. The earphone body is provided with an audio source, and the support frame is installed on the earphone body and corresponds to the audio source. When in use, the support frame is configured to be firmly plugged into the cavum concha of the wearer to allow the earphone body to be worn on the ear of the wearer. The audio source corresponds to the ear canal of the wearer through the support frame, so that the sound emitted from the audio source is transmitted into the ear canal through the support frame.
Further, an audio guide hole is formed in the support frame, and the audio guide hole of the support frame tightly adheres to the audio source. The audio guide hole is configured to transmit the sound emitted from the audio source into the ear canal.
Further, the earphone body includes a housing and an installation cavity arranged in the housing. The housing is provided with an installation hole, and the installation cavity is communicated with the outside through the installation hole. The audio source includes an audio board, and the audio board is installed inside the installation hole.
Further, the support frame tightly adheres to the housing, and the support frame surrounds the audio board through the audio guide hole.
Further, the housing is provided with a buckle, and the buckle is located outside the installation hole. The support frame is provided with a clamping slot cooperating with the buckle, and the support frame is connected to the buckle through the clamping slot.
Further, the opening of the clamping slot forms an extension part cooperating with the clamping slot. When the support frame is installed on the housing, the extension part wraps the buckle and abuts the housing.
Further, the audio source includes a speaker. The speaker is installed inside the installation cavity, and the speaker corresponds to the audio board. The sound emitted from the speaker is transmitted to the outside of the installation cavity through the audio board.
Further, the audio board is provided with a plurality of audio holes penetrating through the audio board.
Further, the support frame is made of soft and comfortable material.
In summary, the advantages of the present invention are as follows:
Compared with the prior art, the present invention provides an open-ear Bluetooth® earphone. When the support frame is plugged into the cavum concha of the ear, the audio source of the earphone body corresponds to the ear canal through the support frame and the audio source faces the ear canal, so that the audio source is directly opposite the ear canal through the support frame to shorten the distance between the audio source and the ear canal, and the sound emitted from the audio source is transmitted into the ear canal through the support frame, which is beneficial for the wearer to hear the best audio to improve the wearing experience of the wearer. The support frame is made of soft and comfortable material to reduce the squeeze of the support frame on the ear, which is conducive to improving the comfort of wearing. According to the different sizes of cavum conchae of different wearers, the support frame can be made in different sizes to adapt to different wearers. The present invention solves the problem that the distance between the audio source and the ear canal of the prior open-ear Bluetooth® earphone is large and the positions of the audio source and the ear canal cannot be accurately located. In this way, without being affected by the size of the ear of the wearer, the shape and size of the outer contour of the ear, and the like, the positions of the audio source and the ear canal are accurately located.
