Description

Technical Field

[0001] This invention relates to the field of headphone technology, and in particular to a four-in-one in-ear hearing aid headphone. Background Technology

[0002] Bone conduction headphones and in-ear air conduction headphones are two completely different types of headphones.

[0003] Both bone conduction hearing aids and in-ear air conduction headphones use a microphone to pick up external sound sources, which are then converted into electrical signals by a control circuit. Bone conduction hearing aids output bone conduction vibration waves through a vibration unit, making them particularly suitable for people with normal skull and other bone tissues but with damage, inflammation, or functional degeneration of the ear canal, eardrum, middle ear, or inner ear. In-ear air conduction headphones, on the other hand, output sound waves conducted through the air via a speaker, making them suitable for people with normal eardrum and cochlea but with skull damage, degeneration, or tissue lesions.

[0004] However, in terms of audiovisual effects, bone conduction hearing aids have relatively greater sound leakage and distortion compared to in-ear air conduction headphones. Bone conduction hearing aids are not suitable for individuals with hearing loss but some degree of hearing impairment, such as damage, degeneration, or tissue lesions in their skull or other bone tissues. They will not be able to hear clearly using bone conduction headphones alone. Furthermore, this specific group already has varying degrees of hearing loss, and they will also not be able to hear clearly using in-ear air conduction headphones. Additionally, in-ear air conduction headphones will also be ineffective for individuals with outer or middle ear damage or those with otitis media.

[0005] Therefore, there is a need to develop a type of hearing aid that can be used by people with different types of hearing loss. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a four-in-one in-ear hearing aid that is flexible in use, has good compatibility and versatility, is suitable for people with different types of hearing loss, and has a better hearing aid effect.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a four-in-one in-ear hearing aid, comprising left and right earpieces, at least one earpiece being equipped with a control circuit and a microphone, the microphone being electrically connected to the control circuit.

[0008] Each earphone has a shell. The first side of the shell contains a bone conduction hearing aid that transmits vibration waves directly to the cochlea via bone conduction, bypassing the eardrum. The second side contains a speaker that transmits sound waves to the eardrum via air conduction.

[0009] The control circuit is electrically connected to the bone conduction hearing aids and speaker output devices of the left and right earphones respectively, and is used to control the two bone conduction hearing aids and the two speaker output devices to simultaneously output the audio signals input to the control circuit by the pickup.

[0010] Each of the earphones includes a bone conduction shell on a first side, a connecting arm in the middle, and an air conduction shell on a second side.

[0011] The inner surface of the bone conduction shell is provided with a bone conduction plate. The bone conduction hearing aid includes a bone conduction vibration assembly installed in the inner cavity of the bone conduction shell and a bone conduction vibration plate that is attached and fixed to the inner surface of the bone conduction plate.

[0012] The speaker-generating device includes a speaker installed in the inner cavity of the air-conducting housing and an in-ear earplug fixed to the outer end of the air-conducting housing for sealing into the external auditory canal.

[0013] The in-ear earbuds are tilted relative to the bone conduction plate, with the outer end of the in-ear earbud protruding from the inner side of the bone conduction plate. When the in-ear earbuds are inserted into the external auditory canal of the human ear, the bone conduction plate is in contact with the skin on the front side of the human ear.

[0014] The bone conduction shell, the connecting arm, and the air conduction shell of each earphone are integrally formed and connected as one unit, and the inner cavity of the bone conduction shell, the inner cavity of the connecting arm, and the inner cavity of the air conduction shell of each earphone are sequentially connected.

[0015] Each earphone is equipped with an earphone cable that runs through the upper part of the bone conduction shell.

[0016] The headphone cable includes a set of bone conduction audio cables and a set of speaker audio cables.

[0017] The bone conduction audio line is electrically connected to the bone conduction vibration assembly.

[0018] The speaker audio cable is electrically connected to the speaker.

[0019] The inner cavity of the connecting arm is configured as a thin channel in the shape of a sheet. A flexible thin film circuit is installed in the thin channel. The first end of the flexible thin film circuit extends into the inner cavity of the bone conduction shell and is electrically connected to the speaker audio line. The second end extends into the inner cavity of the air conduction shell and is electrically connected to the speaker.

[0020] It also includes a main unit, which is equipped with a battery that is electrically connected to the control circuit. The left and right earphones are respectively wired to the main unit via earphone cables. The control circuit is located in either the main unit or one of the left and right earphones.

[0021] The control circuit includes a control unit and an audio frequency division processing unit. The microphone is electrically connected to the control unit, which is electrically connected to the audio frequency division processing unit. The audio frequency division processing unit is electrically connected to the bone conduction hearing aid device and the speaker device of the left and right earphones, respectively. The audio frequency division processing unit sends only mid-frequency and / or high-frequency mid-high audio signals to the bone conduction module, and only mid-frequency and / or low-frequency mid-low audio signals to the bone conduction module, in order to enhance the sound reproduction effect of multi-directional stereo sound.

[0022] Each of the left and right earphones is equipped with a microphone, and the control unit is electrically connected to the two microphones respectively.

[0023] The control circuit is equipped with an audio output control unit for controlling the on / off of audio signals from the two bone conduction hearing aids and the two speaker sound-producing devices respectively. The control unit is electrically connected to the audio output control unit, and the audio output control unit is electrically connected to the audio frequency division processing unit respectively.

[0024] The advantages of this invention compared to the prior art are: this invention is equipped with two bone conduction hearing aids and a speaker sound-generating device, with four sound-generating units conducting sound waves simultaneously, resulting in better hearing aid effect. It is suitable for people with damage, inflammation or functional degeneration of the ear canal, eardrum, middle ear or inner ear, as well as specific people with damage, degeneration or tissue lesions of the skull and other bone tissues. It is flexible in use and has good compatibility and versatility. Attached Figure Description
