Behind-the-ear hearing aid
The invention refers to a behind-the-ear hearing aid comprising a housing having a battery compartment opening through which a battery compartment including a battery may be inserted into the housing, and comprising a frame arranged in the housing and supporting electric components.
Behind-the-ear hearing aids (BTE hearing aids) comprise a housing retained at the ear by a bracket. Generally, the housing is longitudinal and bent corresponding to the ear. With most devices, the housing is composed of a left and a right housing shell. The electric components and other components are placed into one of the two shells. Then, the other shell is set thereon and screwed to the first shell. With other known apparatus, the housing is divided into a top part and a bottom part, the bottom part resting at the ear. The electric components are mounted into one of both parts. Thereafter, the other housing part is placed thereon and connected with the first housing part.
US 6,731, 770 Bl describes a behind-the-ear hearing aid having a battery compartment at the rear end of a housing. The battery contained in the battery compartment can be removed and be replaced with an extra module to be plugged onto the housing, which module in turn includes a battery. The extra module comprises a corresponding plug which is adapted to be plugged into the empty battery compartment. Such a hearing aid has relatively large dimensions, especially because of the extra module. Besides the battery compartment opening, the housing further has another opening for mounting the components of the hearing aid in the housing, this other opening being closed with a lid. It is an object of the present invention to provide a BTE hearing aid wherein the number of housing parts is reduced so that the mounting is facilitated and the tightness of the housing is improved.
The BTE hearing aid of the present invention is defined in claim 1. According to the invention, the frame is dimensioned such that the entire frame, together with the components fastened thereto, can be inserted into the housing through the battery compartment opening.
The invention allows to generally configure the housing as a single part so that no mounting gap is formed at the housing. Among others, this improves the tightness of the housing. The housing itself requires no mounting operations. The battery compartment opening is arranged and dimensioned such that the frame equipped with components can be inserted therethrough. The battery compartment opening is closed with a battery compartment lid mounted at the frame.
In a preferred embodiment of the invention it is provided that the battery compartment lid is connected to the housing through a hinge and that the frame can be inserted into the housing through the battery compartment opening only when the hinge is disassembled. Preferably, the hinge is configured and arranged such that it pivotally connects the battery compartment lid with the frame and at the same time locks the frame in the housing. The hinge may comprise a demountable hinge pin retained in holes in the housing.
The battery compartment opening is located in such an area of the housing that the frame, which substantially fills the housing, can be inserted therethrough. Preferably, the battery compartment opening is provided at an end of the housing or at the transition between the end of the housing and a rear surface.
The following is a detailed description of an embodiment of the invention with reference to the drawings. In the Figures:
Figure 1 illustrates the hearing aid in the disassembled state, and
Figure 2 illustrates the introduction of the frame into the battery compartment opening.
In the embodiment illustrated, the hearing aid comprises an elongate housing 10 bent approximately like a banana so that it conforms to the exterior curvature of the ear. The housing 10 has two side walls 11, 12 connected by a bottom wall 13 and an opposite rear wall 14. the housing 10 has a front end 15 and a rear end 16. The rear end 16 is closed with a rear wall 17, whereas the front end 15 is open.
Adjoining the rear wall 17, an elongate battery compartment opening 18 is provided in the rear wall 14, which extends across the full width of the housing 10. At the front end, the battery compartment opening 18 is limited by a web 19 that is part of the rear wall 14. Further, the rear wall 14 is provided with an opening 20.
The frame 25 is a part of the housing 10. the frame is an insert or component support adapted to be fittingly introduced into the housing 10. A connector 26 is situated at the front end of the frame, which projects from the open front end 15 of the housing and is connected to a counter connector 27 of a sound conductor 28. The sound conductor 28 comprises a tube 29 whose sound outlet is placed in the ear.
The frame 25 carries a rear microphone 30 and a front microphone 31 to receive sound. The rear microphone 30 is arranged behind a sound transmission opening 32 of the housing 10. The frame includes an amplifier (not illus¬ trated), as well as a filter device and a loudspeaker. Further, a lid 33 is mounted to the frame 33, which has pivot arms 34 connected to the frame through hinges 35. The lid 33 fills the opening 20. Below the lid, an operator device 36 in the form of a programming jack or a trimmer is situated. If the hearing aid is programmable through a remote control, the operator device 36 and the lid are not required. The opening 20 of the housing 10 can then be closed.
The battery compartment 40 is located in the rear portion of the frame 25. It consists of the battery compartment lid 41 and, below the same, the ring 51 for receiving the battery 48. A handle and closing member 42 is provided at the battery compartment lid. The battery compartment 40 has the shape of a ring 51 whose axis extends rectangular to the side walls 11, 12 of the housing 10 and which receives the battery 48 in the form of a typical button cell that is set into the ring 51. The frame 25 is provided with battery contacts 43 that contact the contact surfaces of the battery 48 when the battery compartment is closed.
The battery compartment 40 is pivotally fastened to the housing 10 through a hinge 44. The hinge 44 comprises a hinge pin 45 that is passed through holes 47 in the side walls of the housing 10, holes 46 in the frame 25 and the hole 50 in the ring 51 of the battery compartment 40.
At the rear end, the frame 25 has two parallel legs 55, 56 defining a receiving chamber 57 for the battery compartment 40 retractable from the housing 10. When the frame 25 is inserted into the housing 10, the receiving chamber 57 is closed by the battery compartment lid 41 pivoted into the closed position, the battery being pushed between the contact terminals provided at the frame.
Upon mounting, the frame 25 equipped with the electric components is inserted into the housing 10 through the battery compartment opening 18 from the rear end so that the connector 26 projects from the front end 15. The lid 33 closes the opening 20 and the battery compartment lid 41 closes the battery compartment opening 18. Then, the hinge pin 45 is inserted through the holes 46, 47, 50 and fixed. Thereby, the battery compartment is pivotally fastened to the frame 25. At the same time, the hinge pin 45 fixes the frame 25 to the housing 10 and prevents the frame from being pulled out. With the frame 25 mounted in the housing 10, the battery compartment 40 can be pivoted about the hinge pin 45 together with the battery compartment lid 41 so that the battery compartment is accessible from outside for replacement of the battery.
Different from the embodiment illustrated, it is also possible to provide the battery compartment opening 18 immediately at the rear end 16 and to insert the frame through this open end.
The above described principle allows to insert the frame through an opening existing in the housing, i.e. the battery compartment opening serving to replace the battery. Therefore, this solution requires no additional openings in the BTE housing. The frame is inserted into the housing from the end thereof by pushing it in one direction which is substantially parallel to the longitudinal axis of the housing. Thus, optimum use can be made of the inner space of the housing, other than with a solution where the frame is inserted through another opening, thus representing an "angled introduction" which makes additional demands to the design of the frame that can result in unused space remaining in the housing when the frame is inserted.
