Description

Embodiments relate to a hearing aid.

A hearing aid is usually fitted in or behind the ear of the user to amplify the sound for the user. Some popular types of hearing aids include behind-the-ear (BTE) aids, in the ear (ITE) aids, in the canal (ITC) aids, completely in the canal (CIC) aids, etc.

The hearing aid usually includes a hearing aid housing within which a microphone for collecting sound waves, a signal processing circuit (also referred to as a speech processing circuit) for processing the collected sound waves and a loudspeaker (which may also be referred to as a receiver in the field of hearing aids) may be housed. To provide power for the microphone, the signal processing circuit and the loudspeaker, the hearing aid usually includes a battery chamber housing, also referred to as a battery door, coupled to the hearing aid housing to receive a battery. In addition, for charging of the battery, the hearing aid usually includes charging pins.

FIG. 1A and FIG. 1B show a respective perspective view and side view of a conventional behind-the-ear (BTE) hearing aid 102. The hearing aid 102 may include a hearing aid housing 104, a battery chamber housing (not shown) coupled to the hearing aid housing 104 and two charging pins 108, 110 (only the first charging pin 108 is shown in FIG. 1A and FIG. 1B in respective enlarged views) for charging the battery (not shown) housed within the battery chamber housing.

The hearing aid housing 104 may accommodate a microphone, a signal processing circuit and a loudspeaker. The battery chamber housing may be pivoted into or out of the hearing aid housing 104. The battery chamber housing may receive a battery used for driving the hearing aid 102.

Each of the two charging pins 108, 110 may be exposed after being assembled into the BTE hearing aid 102. Therefore, each of the two charging pins 108, 110 may be in direct contact with the skin of a hearing aid user, resulting in a likely deposition of dirt and a likely electrical contact with the hearing aid user. Therefore, it may be desired to prevent physical contact of each of the two charging pins 108, 110 with the skin of the hearing aid user.

In various embodiments, a hearing aid may be provided, which may include a protective cover for each charging pin which may prevent direct contact of the charging pin with the hearing aid user.

In an embodiment, the first charging pin and the second charging pin are respectively inserted into the first protective cover and the second protective cover before being assembled into the hearing aid housing. In this regard, the first protective cover and the second protective cover respectively protrude externally from the first hearing aid housing portion and the second hearing aid housing portion but not the first charging pin and the second charging pin. In this regard, the first charging pin and the second charging pin may be considered to be concealed or may not be directly in contact with a hearing aid user, in particular not with the skin of a hearing aid user.

In an embodiment, when the hearing aid is placed in the charger, the corresponding charging contacts from the charger may respectively be inserted into the first protective cover and the second protective cover to physically contact the first charging pin and the second charging pin to recharge the battery.

In an embodiment, the introduction of the first protective cover and the second protective cover may prevent any direct contact of the first charging pin and the second charging pin with the hearing aid user's skin. The respective first and second protective covers may also help to minimize direct contact of the hearing aid user's perspiration with the respective first and second charging pins. Further, the respective first and second protective covers may prevent the deposition of dirt on the respective first and second charging pins.
