TECHNICAL FIELD
[0001] The utility model relates to a hearing aid technical field especially earplug of preventing deaf and hearing aid. BACKGROUND
[0002] Hearing aid is the equipment for providing hearing aid for the hearing impaired, and the existing hearing aid generally comprises a microphone for receiving external sound, a receiver for transmitting sound to the ear, and an electric control processing device, an ear hanging type hearing aid is connected with an earplug through a sound guide pipe, and the earplug is used for plugging into the external auditory canal to transmit the processed sound into the user's ear.
[0003] In order to ensure that the sound can be transmitted into the ear as much as possible without dispersion, the earplug is usually arranged to be tightly fitted with the ear canal, which can make the sound completely transmitted into the ear, and it is very beneficial for the patients with severe hearing impairment, but for the patients with slight hearing impairment, the sound will be reflected in the ear canal, and due to the sealing limitation of the earplug and the ear canal, a dull sound will be formed in the ear, causing the phenomenon of deafness, which makes the patients with slight symptoms feel uncomfortable, and in addition, for the patients with sensitive ear canal, the form of complete contact and sealing of the earplug and the ear canal will also cause wearing discomfort. SUMMARY
[0004] In order to overcome the defects of the prior art, the purpose of the utility model is to provide an earplug and a hearing aid, which has the advantages of effectively reducing deafness and improving wearing comfort.
[0005] The purpose of the utility model is realized by the following technical scheme:
[0006] According to the first aspect of the embodiment of the present disclosure, an earplug for preventing deafness is provided, which comprises an integrally formed base part and a sound guide part, the base part is provided with an annular sealing area for sealing and fitting with the edge of the ear canal, the sound guide part is used for extending into the ear canal to transmit sound, the size of the sound guide part is smaller than the size of the ear canal, so that the sound guide part is at least partially not in contact with the ear canal when the earplug is worn on the ear; the base part is provided with a through sound hole, the first end of the sound hole is located inside the annular sealing area, and the second end is located outside the annular sealing area to pass through the inside and outside of the ear canal.
[0007] When the earplug is worn on the ear, the annular sealing area is sealed and fitted with the edge of the ear canal, so that the sound transmitted into the ear will not be dispersed, ensuring that the patient can clearly hear the sound, so as to not affect the normal function of the hearing aid, and since the size of the sound guide part is smaller than the size of the ear canal, a gap can be formed between the sound guide part and the ear canal, so that the reflected sound can be dissipated, and then the diffused sound is transmitted out of the ear through the sound hole, thereby reducing the dull sound in the ear and effectively alleviating the deafness phenomenon, which is more comfortable for patients with slight symptoms.
[0008] In some example embodiments, a transition region is formed between the base portion and the sound guide portion, and the transition region is used for the sound muffling air holes to pass through.
[0009] The above technical solution is implemented, and because the overall shape of the base portion and the sound guide portion is changed, the forming of the transition region can increase the opening range of the air holes, thereby adaptively expanding the size of the sound muffling air holes, shortening the distance between the air holes and the outside world, and effectively improving the ventilation effect.
[0010] In some example embodiments, a sound guide hole is formed in the sound guide portion, and a sound guide tube is inserted into the sound guide hole to conduct sound.
[0011] The above technical solution is implemented, the sound guide tube is connected to the receiver, and the sound guide tube is inserted into the sound guide hole and extended to be substantially flush with the surface of the sound guide portion, so that sound is effectively transmitted into the ear.
[0012] In some example embodiments, the front end of the sound guide portion is arc-shaped.
[0013] The above technical solution is implemented, and the wearing process is more comfortable.
[0014] In some example embodiments, the base portion is further connected with an auxiliary sealing portion, and the surface of the auxiliary sealing portion is used to contact and seal with the auricle portion.
[0015] The above technical solution is implemented, and the auxiliary sealing portion is used to contact and seal with the auricle portion, thereby further preventing sound from overflowing and improving the hearing aid effect.
[0016] According to a second aspect of the embodiments of the present disclosure, a hearing aid is provided, which comprises the anti-ear-blocking ear mold of the first aspect.
[0017] In summary, compared with the prior art, the present application has the following beneficial effects:
[0018] This utility model provides an anti-occlusion earmold and a hearing aid. The anti-occlusion earmold includes an integrally formed base and a sound-conducting part. The base has an annular sealing area for sealing and fitting against the edge of the ear canal. The sound-conducting part is inserted into the ear canal to transmit sound. The size of the sound-conducting part is smaller than the size of the ear canal so that when the earmold is worn on the ear, the sound-conducting part does not contact the ear canal at least partially. The base has a through-hole for silencing. The first end of the silencing hole is located inside the annular sealing area, and the second end is located outside the annular sealing area to penetrate the inside and outside of the ear canal. When the earmold is worn in the ear, the annular sealing area fits snugly against the edge of the ear canal, preventing sound from being dispersed when it enters the ear and ensuring that the patient can hear clearly without affecting the normal function of the hearing aid. Because the size of the sound guide is smaller than the size of the ear canal, a gap can be formed between the sound guide and the ear canal, allowing the sound to reflect and dissipate. Then, the diffused sound is transmitted to the outside of the ear through the sound-absorbing vent, thereby reducing the muffled sound in the ear and effectively alleviating the ear blockage phenomenon. This provides better comfort for patients with mild hearing loss. Attached Figure Description
