Abstract
Description
Technical Field
[0001] This application relates to the field of hearing aid technology, and in particular to a detachable hearing aid. Background Technology
[0002] Bluetooth hearing aids are devices designed specifically for people with hearing impairments to help them improve their hearing. Compared to traditional hearing aids, Bluetooth hearing aids typically have a wider range of applications, a wider volume adjustment range, richer sound quality, and longer standby time. They are suitable for use in specific environments. They can connect to a mobile phone to listen to music or make phone calls, or switch to hearing aid use.
[0003] Current Bluetooth hearing aids are usually wired and worn, worn on the body to pick up sound and transmit it to the earphone via wires. Because the hearing aid's sound pickup device is located on the user's body, the purpose of sound pickup is to capture sounds from a distance or the surrounding environment. However, because it also records the user's own voice at the same time, when the user speaks at the same time, the sound of distant or surrounding targets will be low, resulting in unclear sound pickup. Utility Model Content
[0004] This application aims to solve the technical problem that hearing aids are usually worn on the body to pick up sound and transmit it to headphones via wires. However, hearing aids are located on the user's body and pick up sounds from a distance or surrounding area. However, because the user's own voice is loud, the sound pickup is unclear when they speak at the same time. The application provides a detachable hearing aid headphone.
[0005] This application employs the following technical means to solve the technical problem:
[0006] A detachable hearing aid includes a wearable component, a magnetic backplate, a magnetic main unit, and TWS earphones;
[0007] The wearable device is connected to the magnetic back panel, and the magnetic main unit is magnetically connected to the magnetic back panel. The magnetic main unit has slots on both sides, and the TWS earphones are adapted to the slots.
[0008] Furthermore, the wearable device includes, but is not limited to, a neck strap and a watch strap.
[0009] Furthermore, the magnetic backplate and the magnetic main unit are connected to each other by magnetic attraction.
[0010] Furthermore, volume buttons are provided on both sides of the magnetic host.
[0011] Furthermore, a switch button is provided at the center of the magnetic suction host.
[0012] Furthermore, the magnetic host and the earphones are connected via Bluetooth.
[0013] This application provides a detachable hearing aid headphone, which has the following beneficial effects:
[0014] Previously, it was a wired wearable device (the main unit and the earphones were inseparable; the main unit transmitted the hearing aid signal to the earphones via a wire; Bluetooth was only used to connect to a mobile phone to answer calls or listen to music). The current one should be defined as a wireless wearable device (the main unit and the earphones can be separated).
[0015] They are connected via Bluetooth technology, meaning the main unit has a Bluetooth device and a hearing aid device. When the hearing aid picks up sound, Bluetooth wirelessly transmits the processed sound signal to two earphones that also have Bluetooth.
[0016] When the host device's Bluetooth is connected to a mobile phone, it receives the phone's signal and simultaneously forwards the signal to the Bluetooth headset, enabling calls and music playback. Attached Figure Description

[0026] Reference Appendix Figure 1-4 This is a schematic diagram of the structure of a detachable hearing aid headphone in one embodiment of this application;
[0027] A detachable hearing aid includes a wearable component, a magnetic backplate 7, a magnetic main unit 1, and an earphone 4.
[0028] The wearable device is connected to the magnetic back plate 7, and the magnetic host 1 is magnetically connected to the magnetic back plate 7. The magnetic host 1 has slots 6 on both sides, and the earphone 4 is adapted to the slots 6.
[0029] In this embodiment, the wearable device includes, but is not limited to, a neck strap 5, a watch strap 7, and an ankle strap 5.
[0030] The magnetic backplate 7 and the magnetic host 1 are connected to each other by magnetic attraction.
[0031] Volume buttons 2 are located on both sides of the magnetic host 1.
[0032] A switch button 3 is located at the center of the magnetic host 1.
[0033] The magnetic host 1 and the earphone 4 are connected via Bluetooth.
[0034] Specifically, the user secures the device to their neck or wrist using a headband or watchband-style headband. Then, the user presses the power button 3 to activate the magnetic host 1. Once the magnetic host 1 is powered on, the user puts on the earphones 4, which connect to the magnetic host 1 via Bluetooth. The magnetic host 1 has two modes: a hearing aid mode, where the user can remove the magnetic host 1 from the magnetic backplate 7 and place it in the center of a meeting or conversation to pick up sound. After picking up the sound, the magnetic host 1 uses Bluetooth and a built-in algorithm to reduce ambient noise and amplify the voice before transmitting it to the user's earphones 4. When the hearing aid mode is no longer needed, the magnetic host 1 can be placed back on the magnetic backplate 7 for neck or wrist wear. The other mode is a mobile phone connection mode, where the magnetic host 1 connects to a mobile phone via Bluetooth, GPS, infrared, or 4 / 5G signals. This allows the phone's audio to be transmitted to the earphones 4. Furthermore, the volume buttons 2 on both sides of the magnetic host 1 allow for independent volume adjustment of the left and right earphones.
[0035] Among them, the magnetic host 1 can be worn and placed freely at the target point. The magnetic host 1 records the sound and amplifies it, and transmits it to the user's TWS earphones through Bluetooth technology.
[0036] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
