DESCRIPTION

OBJECT OF THE INVENTION

The object of the present invention relates to a hearing aid, in the form of an earring or decorative accessory that improves the hearing of people who have it in a reduced way (hearing loss) so that the aesthetic does not present a visual impact on the wearer.

Therefore, the hearing aid object of the present invention comprises a digital device that is placed in the earlobe by its anterior part, and that is connected to a battery located at the back of the lobe, through the battery holder, which in turn has a connector that crosses the hole of said lobe also serving as a fastener to the device.

Find special application in the field of prosthetic audiology industry.

TECHNICAL PROBLEM TO BE RESOLVED AND BACKGROUND OF THE INVENTION

At present, to improve the hearing of people who have diminished this sense, the "retro-auricular" hearing aid that is placed on the auditory pavilion is usually used, and that through a hollow tube transmits the sound to the ear. These hearing aids have the disadvantage that the battery is inserted into the device itself, and to provide the output power and extend the battery life, the devices become larger. Currently, smaller hearing aids have been achieved by placing the earpiece directly in the ear canal, but they do not have enough power or have high battery consumption. In both cases, the aesthetic appearance of the hearing aid makes it unattractive.

Another solution in the field of hearing aids, are those that are housed directly within the ear canal or in its outermost area. These hearing aids have all their means inside the same housing, and are defined as "intra-ear" headphones. These types of hearing aids are more discreet than "retro-headphones", however, they have to be custom-made, and they show greater deterioration due to direct contact with earwax and sweat, in turn, they usually occlude the ear canal external, which provides a plug sensation in the ear. There are, in turn, other hearing aids, already in disuse, such as the pouch hearing aid, which includes headphones with cables, which have been gradually disappearing from the market, due to their lack of practicality, their excessive weight and their few aesthetic qualities

An example of a similar technical solution is the Spanish patent ES 2 287 975T3 which describes a hearing aid, which comprises an electronic part, in which the sound is amplified, and an air conduction channel having an inlet end and an end of exit and that is adapted to be surgically implanted in the skull bone, so that the exit end opens in the middle ear towards the inside of the eardrum, characterized in that the electronic part is acoustically connected to the entrance end of the channel of air conduction for the purpose of transporting amplified sound vibrations through said channel to the middle ear to stimulate vibration of the eardrum from the inside.

The hearing aid object of the present invention has found a simple and effective solution to the disadvantages and disadvantages of hearing aids known in the prior art described above.

Therefore, the present invention solves the aforementioned prior art problems by providing a hearing aid that has the following advantages:

1. Its main use is, like any hearing aid, to mitigate problems arising from the loss of hearing ability (hearing loss), but, unlike other hearing aids, the same device is used regardless of the degree of hearing loss.

2. It has been possible to design with a slope so that its aesthetic does not present a visual impact on the wearer.

3. Separate the battery from other electronic media, thus decreasing its heating and, therefore, improving its functionality.

4. The battery holder has different sizes according to the different batteries without altering the size of the hearing aid. Thus, the size of the battery does not condition the shape and size of the case.

5. The batteries can be rechargeable or not.

6. Allows the use and manufacture of batteries with different designs and greater load than the which are currently being used to improve and expand the hearing aid performance.

7. Thanks to its small size, and its internal electronic means, said hearing aid can also be used as a wireless headset or as a wireless device.

8. Allows you to adapt the battery to the energy needs of the headset.

9. The hearing aid is not in direct contact with sweat, earwax or earwax; This makes it more hygienic than what exists today and allows prolonging the life of the device.

10. Allows mass production of the same housing design for any degree of hearing loss.

1 1. Add the possibility to the user of an easy change of external appearance by exchanging a bezel.

12. Allows the manufacture of infinity of bezel and shell designs to vary its exterior appearance.

13. Its earring aspect facilitates the use for both ears, improving the quality of hearing and the combined use of the two hearing aids.

14. Allows easy access and replacement of all hearing aid components.

15. It is placed easily and simply, especially for people who are used to wearing earrings

DETAILED DESCRIPTION

The object of the present invention relates to a hearing aid (1) in the form of an earring or decorative accessory that attenuates the problems derived from the loss of hearing ability (hearing loss) and also makes the hearing aid aesthetics (1) not present visual impact on the carrier.

The hearing aid (1) mainly comprises:

- electronic means (2);

- a first casing (4) protecting said electronic means (2),

- a second housing (5) where the first housing (4) and a part of the ear tube (7) are anchored;

- an ear tube (7) connected to the output of the electronic means (2) and directed to the ear canal,

- an external battery holder (8) located at the back of the user's earlobe (13), and

- a connector (10) that crosses the earlobe (13) and connects the external battery holder (8) to a connection hole (6) disposed in the first housing (4).

The external battery holder (8), which comprises a battery (9), is physically connected to the first housing (4) and electrically to the electronic means (2) by means of the connector (10), said external battery holder being ( 8) and said battery (9) easily interchangeable.

Unlike the current hearing aids, this hearing aid (1) comprises the battery (9) separated from the electronic means (2) so that it allows to manufacture batteries (9) with a larger size (larger load capacity) than the battery sizes (9) current, thus improving benefits.

As can be seen in figures 1A, 1 B, 2A, and 2B, the first housing (4) together with the electronic means (2) are located in the front part of the earlobe (13) and the holder - External batteries (8) together with the battery (9) are located at the back of the patient's earlobe (13). However, the external battery holder (8), the battery (9), the ear tube (7), the headset (17) and a second microphone (25) could be placed in the anterior part of the earlobe (13 ) and the electronic means (2) at the back of the earlobe (13), as seen in Figures 9 and 10.

The size of the battery (9) does not condition the size and shape of the hearing aid (1) as it is separated from the electronic means (2).

Additionally, placing a battery (9) and electronic media (2) separately reduces excessive overheating of electronic media (2) due to the battery (9).

In addition, the hearing aid (1) has an aesthetic and an ideal size to go completely unnoticed since it has shape, size, appearance and location of earring or decorative accessory.

The hearing aid (1) is placed easily and simply, especially for people who are used to wearing earrings.

The electronic means (2) are selected from at least the set consisting of:

- a female power plug (14),

- a microcontroller (15) responsible for sound processing and connection with other external devices,

- a microphone (16) facing outwards so that it achieves a better location of the sound,

- a headset (17),

- a headphone jack (27),

- a button (24) that changes the programming of the micro-controller (15),

- sufficient wiring for the connection of the electronic means (2), and

- a means for the transmission of data which may be either a data transmission plug to a PC (20) or a wireless communication module (21),

- an induction coil (32) that increases the possibilities of access to sounds, and

- a potentiometer (18) for volume control.

The electronic media (2) includes the induction coil (32) that is activated and connected to the induction coil loop systems (32), increasingly existing in public places (shopping malls, cinemas, halls conferences, ...) These systems they emit the sound wirelessly, so that the induction coil (32) of the hearing aid (1) picks it up.

The control of the output power (volume) of the hearing aid (1) is performed automatically by the microcontroller (15) or it may require the use of a push button (24) and / or a potentiometer (18) depending on the technology used by the microcontroller (15).

The first housing (4) may comprise a slot for the flexible cable data connection (29) in the event that the hearing aid (1) needs to be connected to a PC for data transmission, as observed in the figure 4C.

Depending on the output power of the headset (17), a battery (9) with more or less charge needs to be used. The hearing aid (1) allows the use of the battery (9) suitable for each earpiece (17) necessary to cover the different degrees of hearing loss.

In a first embodiment, the external and visible part of the hearing aid (1) is formed by a second housing (5) that gives the appearance of a slope to the hearing aid (1) and is anchored to the first housing (4), such and as can be seen in figures 1A and 1 B.

This second housing (5), as a cover of the electronic means (2), can have various shapes and can incorporate any decorative element to vary its aesthetic appearance. Additionally, said second housing (5) comprises a plurality of small holes (1 1) for sound input. It can be seen in Figure 4A.

The second housing (5) is anchored by pressure to the first housing (4), so that the electronic means (2) can be easily accessed. Said second housing (5) could also be anchored to the first housing (4) by means of a threaded closure, pin closure, elastic jump closure or any other method known to a person skilled in the art.

In a second embodiment, the external and visible part of the hearing aid (1) is formed by a bezel (12) that is anchored to the second housing (5), as seen in Figures 2A, 2B and 8.

The bezel (12) allows the external appearance of the hearing aid (1) to be exchanged with different shapes and colors, allowing the use of the same materials used for jewelry, and in turn protects the hearing aid (1) against inclement weather (air, water, sun ...). Figures 2A and 2B show how the bezel (12), which looks like a pearl earring, is on the second housing (5).

The inner part of the bezel (12) is preferably made of foam (interchangeable in case of deterioration) where the density of the foam is such that it allows the bezel (12) to be perfectly anchored to the second housing (5), without damaging it. The anchoring of the trim (12) to the second housing (5) can be done with different anchoring systems already known.

The bezel (12) allows the user to easily exchange the external appearance of the hearing aid (1) without the help of an audiologist or electronic technician, and in turn, protecting the first (4) and the second housing (5).

The first housing (4) comprises a specific shape and size to be able to be located in the front part of the earlobe (13) and serves as protection for the electronic means (2), as can be seen in Figure 4B. However, the first housing (4) can comprise any geometric shape.

In Figures 1 B and 2B it can be seen how the connection hole (6) is located in the lower area of the first housing (4) to decrease the distance of the hearing aid (1) to the ear canal and, therefore, that the ear tube (7) is shorter, so that the ear tube (7) is more discreet.

There is the possibility of incorporating a reinforcing element (3) which is a structure that is placed between the first housing (4) and the second housing (5) to increase the protection of the electronic means (2). In addition, the reinforcement element (3) separates the button (24) and the data transmission plug for PC (20) from other electronic means (2) to facilitate its use, and that the pressure exerted on them in its use does not compromise the proper functioning of other electronic means (2), as shown in figure 12.

In Figure 4D a design is observed in which the first housing (4) and the second housing (5) form an integral piece (34), so that the electronic means (2) are comprised inside in a removable base (33) as a drawer. The microphone (16) comprised inside the first housing (4) is directed forward, in the direction of the patient's gaze, without any occlusion element, so that thanks to the plurality of holes of the second housing ( 1 1) and the plurality of holes in the bezel (28), perfectly captures the sounds from the outside.

The microcontroller (15) transforms the sound captured from the outside by the microphone (16) and by the second microphone (25) and modulates it to adapt it to the needs of the patient's hearing loss.

In the event that the micro-controller (15) uses a space inside the first housing (4) such that it is not possible to install all electronic means (2) correctly, or that a second microphone (25) needs to be used , said microcontroller (15) or said second microphone (25) will be placed in such a way that they use the usual earpiece space (17), and said earpiece (17) will be installed directly in the ear canal.

In the case of needing two hearing aids (1), one for the right ear and one for the left ear, interconnection between them and the combined use of both are possible to improve hearing, as shown in Figure 11.

The second microphone (25) serves to capture the sounds coming from the back of the patient, and is placed either inside the first housing (4) next to the electronic means (2) and directed backwards as observed in Figure 3C, or located outside the first housing (4) and separated from the electronic means (2).

In figure 7 a second microphone (25) can be seen separated in this case from the electronic means (2) and located next to the external battery holder (8).

In figures 3A, 3B and 3C it can be seen how the button (24) is directly operable by pressure and is located so as to provide an easy and simple operation. It would be the same for the potentiometer (18).

The ear tube (7) runs from the hearing aid (1) in the lower part of the ear to the ear canal, describing the characteristic curves of the shell and the beginning of the ear canal that facilitate the hearing aid (1) and allowing adaptation to the ear canal with a micro-mold (31) or by means of a specific funnel-shaped adapter (30). Said specific funnel-shaped adapter (30) allows amplifying the sound.

The ear tube (7) can have different lengths to adapt to different sizes of auditory pavilion.

In a first practical embodiment of the ear tube (7), the ear tube (7) will be hollow when the earpiece (17) is placed internally in the first housing (4) next to the electronic means (2), as can be Observe in Figure 5A, and in a second practical embodiment of the ear tube (7), the ear tube (7) will contain the necessary wiring to place the earpiece (17) externally to the first housing (4) and to the electronic means (2). ), that is, directly in the ear canal, as can be seen in Figure 5B. In figure 2B, the headset (17) placed externally to the first housing (4) and the electronic means (2) can be seen.

Figures 5A, 5B, 5C and 5D show the curved shape of the auditory tube (7).

Figure 3A shows the data transmission plug to a PC (20) and the handset (17) placed next to the electronic means (2); Figure 3B shows a wireless communication module (21) and the headphone jack (27); and in figure 3C the headphone jack (27) is shown; the second microphone (25), directed backwards, and the induction coil (32).

In both Figure 3B and Figure 3C, the headset (17) is not shown as it would be placed directly in the ear canal, that is, externally to the first housing (4) and to the electronic means (2).

As can be seen in the figures, the fact that the ear tube (7) goes from the bottom of the ear and ascends to the ear canal allows it to be hidden so that it is much more aesthetic and comfortable for the patient.

There is the option of placing an additional small holding element (23) that helps keep the ear tube (7) better attached to the ear, as shown in Figure 5A and 5B where the additional holding element (23) is A little ball

The connector (10) of the external battery holder (8) is preferably tubular and crosses the earlobe (13), connecting with a connection hole (6) disposed in the first housing (4) and thus allowing the connection and disconnection of the hearing aid (1), as shown in figures 1 B and 2B.

The connector (10) has a coating of antiallergic material (26) in the section that crosses the earlobe (13) and its connection to the first housing (4) is preferably machi-female type. Said coating of antiallergic material (26) has different thicknesses to adapt it to the different sizes of the diameter of the orifice of the earlobe (13).

The connector (10) can include a notch or half thread in its tip to reaffirm and consolidate the connection to the female power plug (14).

Figure 7 shows an auxiliary connector (35) that can be incorporated into the hearing aid (1) and that passes outside the earlobe (13) to facilitate the connection between the second microphone (25) arranged next to the holder. External batteries (8) and electronic means (2) arranged in the first housing (4). Said auxiliary connector (35) serves to hide the wiring and helps to establish any other additional connection that is necessary between the different electronic means (2).

The placement of the external battery holder (8) is carried out in a comfortable, simple and fast way.

A break in the external battery holder (8) does not prevent the use of the hearing aid (1) as it is easily and quickly replaced.

The placement of the battery (9) by the back of the earlobe (13) balances the weight of the hearing aid (1) by making the first case (4) get closer to the earlobe (13) thus preventing move forward.

The hearing aid (1) can incorporate a buzzer (19), for the transmission of sound by vibration through the bone mastoid, the electronic means (2) being installed in the back of the lobe (13) and the external battery holder ( 8) with the battery (9) in its front part, as can be seen in figure 10.

The hearing aid (1) allows the combined use of earphone (17) and buzzer (19).

The materials used to manufacture all the components meet the necessary standards for use as a medical device and can be applied with a nanotechnology water-repellent treatment.

The external battery holder (8) can have a built-in cover that allows you to replace the battery (9) easily, in case the battery (9) is not rechargeable as you can observe in figure 13B; or it can be airtight in the event that the battery (9) is rechargeable, as can be seen in Figure 13A.

The external battery holder (8) will preferably incorporate an interchangeable battery (9) to adapt to the user's auditory needs, and can be rechargeable by means designed for this purpose. With said means being a charger (22) for batteries (9), in which several batteries (9) can be charged simultaneously without removing them from the external battery holder (8) since said external battery holder (8) would be airtight. In this way, while a battery (9) is being used, other batteries (9) may be charging so that the hearing aid (1) can be constantly in operation. The use of rechargeable batteries (9) reduces environmental pollution.

All hearing aid components (1) are easily interchangeable individually and independently. However, it is possible to add a sealant for the housings (4,5) and the electronic means (2) so that access to the electronic means (2) is impossible.

The present invention should not be limited to the embodiment described herein. Other configurations can be made by those skilled in the art in view of the present description. Accordingly, the scope of the invention is defined by the following claims.
