Description

DESCRIPTION
HEARING AID
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) hearing aids, in- the-ear (ITE) hearing aids, in-the-canal (ITC) hearing aids, completely-in-the-canal (CIC) hearing aids, etc.
A 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.
The hearing aid may also include an add-on accessory configured to be attached to the hearing aid housing. The add-on accessory may be a so-called audio shoe. An audio shoe may be a small device attached to the hearing aid housing and may be used to connect an FM receiver or other similar device. The hearing aid may also include a lock.
As each of the battery chamber housing and the so-called audio shoe may be of a considerable size and weight, thereby contributing to the overall- size and weight of the hearing aid, it may be desired to reduce the size and weight of the hearing aid while providing a reasonable level of safety to a hearing aid user. In various embodiments, a hearing aid may be provided, which may include a lock which may provide an increased latching strength for the hearing aid user while having a reduced size and weight.
