Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a Bluetooth earphone with a noise reduction function. Background Technique

[0002] A Bluetooth earphone is an earphone that applies Bluetooth technology to a hands-free earphone. With its convenience, Bluetooth earphones are increasingly recognized by the market. As people's quality of life improves, people need higher-quality earphones, and the noise reduction function of earphones becomes increasingly important.

[0003] For the existing patent with the publication number CN217216847U and the name "Bluetooth Earphone", this utility model discloses a Bluetooth earphone, which includes a battery case, two earphones, and a locking component. Among them, the battery case is provided with an installation surface, and the installation surface is provided with two accommodation grooves. Each earphone is accommodated in the corresponding accommodation groove. The battery case is also provided with an installation cavity. Communication ports communicating with the installation cavity are provided at positions on the side walls of the two accommodation grooves away from each other. The locking component is installed in the installation cavity and partially exposed outside the battery case. The locking component is used to lock or unlock each earphone synchronously through each communication port. With such a setting, it is convenient for users to take and place the earphones.

[0004] The above device uses the locking component to lock or unlock each earphone synchronously through each communication port. However, the locked charging case is not completely sealed and cannot prevent dust and water from entering, so it cannot well meet people's usage requirements. In view of the above situation, technological innovation is carried out on the basis of the existing Bluetooth earphones. Content of the Utility Model

[0005] The purpose of the utility model is to provide a Bluetooth earphone with a noise reduction function to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A Bluetooth earphone with a noise reduction function includes a charging case and a dust-proof cover. A rubber cover is inlaid below the interior of the charging case, and a charging port is installed above the rubber cover. The dust-proof cover is hinged above the charging case, and a magnet II is bonded to the lower part of the interior of the dust-proof cover. The dust-proof cover and the rubber cover prevent water and dust from entering the charging case.

[0007] Furthermore, a magnet I is inlaid above the interior of the charging port, and a battery I is installed below the magnet I. Under the magnetic force of the magnet I and the magnet II, the sealing ring under the dust-proof cover is closely attached to the charging case.

[0008] Furthermore, earphone slots are provided on both the left and right sides of the battery I, and a charging seat is inlaid below the earphone slots. The battery I charges the charging head through the charging seat, and the charging seat can charge the battery II when it comes into contact with the charging head.

[0009] Further, a housing is provided inside the earphone slot, and a charging head is embedded below the housing. The second battery is charged through the charging head. The housing fits closely with the earphone slot without shaking, preventing the earphone from being damaged inside the charging case.

[0010] Further, a second battery is installed above the charging head, and a Bluetooth module is installed above the second battery. The Bluetooth module receives Bluetooth signals and transmits sounds through the speaker.

[0011] Further, a noise reduction component is provided above the Bluetooth module, and the noise reduction component includes a vacuum bubble and a sound insulation board. The sound insulation board is installed on the left side of the vacuum bubble. When external noise enters the earphone, it is weakened by the vacuum bubble and then reflected by the sound insulation board for a part.

[0012] Further, the noise reduction component further includes a sound transmission tube and a filter screen. The filter screen is provided inside the left side of the housing, and the sound transmission tube is installed on the right side of the filter screen. The filter screen prevents impurities such as dust from entering, and the double-layer hollow structure of the sound transmission tube can effectively isolate external noise.

[0013] Further, a speaker is provided on the right side of the sound transmission tube, and a sound absorption cotton is wrapped around the periphery of the speaker. The sound absorption cotton wrapped outside the speaker absorbs a part of the noise.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the rubber cover is closed, the dust-proof cover is closed with the charging case. Under the magnetic force of the first magnet and the second magnet, the sealing ring under the dust-proof cover is closely attached to the charging case, which is convenient for charging and taking out the earphone, and can prevent water and dust from entering and damaging the earphone. When external noise enters the earphone, it is weakened by the vacuum bubble and then reflected by the sound insulation board for a part. The sound absorption cotton wrapped outside the speaker absorbs a part of the noise. The sound is transmitted through the sound transmission tube, and the double-layer hollow structure of the sound transmission tube can effectively isolate external noise. The filter screen prevents impurities such as dust from entering.

[0015] 1. In the present utility model, the rubber cover is opened to expose the charging port. The first battery is charged through the charging port. The first battery charges the charging head through the charging base, and the second battery is charged through the charging head. After charging is completed, the rubber cover is closed. The dust-proof cover is closed with the charging case. Under the magnetic force of the first magnet and the second magnet, the sealing ring under the dust-proof cover is closely attached to the charging case, which is convenient for charging and taking out the earphone, and can prevent water and dust from entering and damaging the earphone.

[0016] 2. When the user needs to use the earphone of the present utility model, take out the outer shell from the earphone slot and wear it on the ear. The Bluetooth module receives the Bluetooth signal and transmits the sound through the speaker. When the external noise enters the earphone, it is weakened by the vacuum bubbles, and then a part of it is reflected by the sound insulation board. A part of the noise is absorbed by the sound-absorbing cotton wrapped outside the speaker. The sound is transmitted through the sound transmission tube. The double-layer hollow structure of the sound transmission tube can effectively isolate the external noise. The filter screen prevents impurities such as dust from entering, protects the normal operation of the earphone, and prevents noise from affecting the normal use experience of the user.
