Description

Detailed Description of the Invention

The present invention relates to an electro-acoustic transducer module for a hearing aid, which is to be installed behind or in the ear according to the introduction part of claim 1, the hearing aid described in the introduction part of claim 10 and the introduction part of claim 21. The hearing aid manufacturing method described in 1.

[0002] In hearing aids, especially in-ear hearing aids, it is important to have the speaker housing communicate with the ear canal without a mechanically rigid connection. This is to avoid acoustic feedback from the speaker to the microphone on the entrance side of the hearing aid as much as possible. Also, in a hearing aid, the available space is extremely limited, so this narrow space must be utilized to the maximum extent.

In the example of EP 0548580, an electro-acoustic transducer device having a speaker housing is provided in an in-ear hearing aid. In this device, a motor driven speaker diaphragm is provided close to a motor driven device. With respect to the speaker housing, the diaphragm or the motor driven device is configured so that the acoustic signal generated by the diaphragm is directly transmitted to the speaker housing. The electrical / acoustic transducer device is configured within the housing of the in-ear hearing aid such that the speaker housing is as far as possible from the hearing aid housing, thereby reducing the acoustic coupling. However, when assembling and manufacturing a conventional hearing aid, it is necessary to take the utmost care so as not to form the above-mentioned acoustic connection portion, and therefore, in the related art, the transducer device is conventionally manually operated. It is performed by inserting it into the housing and setting it accurately there.

The present invention provides an electric / acoustic transducer module having the features described in claim 1 for the purpose of eliminating such a problem.

In the present invention, the speaker housing is resiliently mounted within the capsule housing, wherein the transducer module is in the rear of the ear or in the hearing aid in the form of fasteners or clamps (kr).
assembled by aftschlussig). Furthermore, the intermediate space between the speaker housing and the hearing aid housing is exploited to improve the acoustics of the hearing aid. That is, in the present invention, the intermediate space is used by being connected to the transducer itself to extend the low frequency region of the transducer module by several dB. This is because, in the present invention, the intermediate space is utilized together with the space on the rear surface of the diaphragm to expand the space exerting the acoustic effect several times as compared with the space on the rear surface of the diaphragm inside the speaker housing itself. Is. The advantage of having more space behind the diaphragm is shown in US Pat. No. 3,257,516.

In one embodiment of the invention, the capsule housing acts as a magnetic shield and is preferably made of μ metal. Assembly and disassembly of the transducer device, in particular the speaker housing and the speaker, is maximally simplified by making the capsule housing a cup-shaped member. The capsule housing is preferably made of metal. In another embodiment, the cup-shaped member is sealed with the end member having the sound outlet of the transducer device after attaching the speaker housing to the speaker. In still another embodiment, the end member has an opening as a sound outlet, and in this opening, the first chamber on one surface side of the speaker diaphragm, which is in communication with the sound outlet of the transducer device, is provided with another diaphragm. To be isolated from the surroundings. The diaphragm is mounted in free vibration above the opening surface. In yet another embodiment, the cup-shaped member is formed at its end by an elastic bag-shaped member. In both the case of the end piece or the elastic bag, a seal is formed inside the transducer device, which ameliorate the problem of acoustically important transfer element contamination, which is known in particular for in-ear hearing aids. It also makes it possible to clean such dirt on the transducer module. In this way, ingress of dirt or moisture into the module is avoided.

Unlike the example described in the above-mentioned European Patent No. 0548580, in the embodiment of the present invention, the diaphragm provided at the sound outlet is mounted in a freely vibrating state and is driven by the motor. Absent. In the present invention, the sizing known to the expert for increasing the acoustic effect in the device and the characteristics of the diaphragm for tuning the acoustic impedance do not interfere with the acoustic transfer performance of the hearing aid at the outlet side of the speaker.

In another embodiment of the invention, at least the free-vibration part of the diaphragm is formed of a homogeneous material, ie a homogeneous material phase, and preferably has a constant thickness. As a result, the manufacturing cost of the diaphragm is greatly reduced, while the acoustic effect of the diaphragm is sufficiently achieved.

In an embodiment of the invention, at least the free vibrating portion of the diaphragm is made of an elastic material,
Most advantageously made in terms of cost, for example latex or silicone rubber.
Further, while the thickness is formed to be uniform and thin, these materials have resistance even in contact with skin and can maintain the effect. The diaphragm is preferably mounted airtight. Further, the thickness d is 0.09 mm or less (d ≦ 0.09 mm).

In order to assemble the speaker housing into the capsule housing as easily as possible while taking into account the acoustic separation between the speaker housing and the capsule housing, the speaker housing is mounted in the capsule housing via the elastic support member.
In addition, in order to make the best use of the intermediate space, the speaker housing is configured to surround the entire surface of the speaker housing with the intermediate space, except for the supporting position of the speaker housing with respect to the capsule housing.

The present invention also provides a hearing aid comprising an electro / acoustic transducer device as described above. Here, in order to make the assembly as simple as possible, the capsule housing with the transducer module is positioned in the hearing aid housing by means of a fastening and / or a fastening force.

Thereby, as will be described below, the hearing aid of the invention forms the basis for assembling a plurality of modules by means of an automated technique. Even in this case, the avoidance of an acoustic connection between the speaker housing and the hearing aid housing can be achieved by the arrangement of the transducer module according to the invention.

In the hearing aid according to the embodiment of the present invention, the sound outlet of the transducer module is connected to the sound outlet opening of the hearing aid housing through the tubular support member as compared with the conventional one.

In a hearing aid according to a further embodiment, the first chamber of the transducer module is isolated from the environment around the hearing aid by a diaphragm attached to the sound outlet in a freely vibrating state. The diaphragm is attachable to the transducer device itself of the invention, while in embodiments it is attached directly to the sound outlet area of the hearing aid housing. This prevents dirt from entering the transducer module as well as the transducer inlet in the hearing aid.

Therefore, also in another embodiment of the hearing aid according to the invention, the sound outlet of the transducer module of the invention is mounted substantially directly at the outlet opening of the hearing aid housing. The diaphragm is thus provided on the one hand in direct contact with the surrounding environment of the hearing aid housing and on the other hand in direct contact with the outlet of the transducer module. As a result, the sound outlet opening of the hearing aid is sealed by the diaphragm, so that the problem of dirt adhering to the sound outlet opening is solved, and
On the other hand, there is nothing added to the transmission path from the sound outlet of the transducer module to the sound outlet of the hearing aid, so that the best acoustic effect can be obtained. Thus, the entire acoustic transfer path can be realized solely on the basis of obtaining acoustic impedance tuning.

In an embodiment of the hearing aid with a particularly preferred construction, the sound outlet opening of the hearing aid housing is formed by a plate-shaped member joined to the end of the hearing aid housing, for example by gluing or welding. In this embodiment, the sound outlet opening is sealed by a diaphragm, which is preferably made in one piece with the plate-shaped member. The integral formation of the diaphragm and the plate-shaped member is similar to that in the above-described various embodiments.
It is premised that the plate member is made of an elastic material such as latex or silicone rubber, like the diaphragm.

The invention also provides a method for manufacturing a hearing aid, in particular a hearing aid according to the invention. In this method of manufacture, the transducer module is positioned and secured within the hearing aid housing by a fastener lock or a clamp force lock. That is, the transducer module can be fixed in the hearing aid housing in a labor-free manner and accurately, by means of fasteners, by pressing between the components of the hearing aid housing, or by fitting in the hearing aid housing. It

Thus, according to the method for manufacturing a hearing aid according to the present invention, it becomes possible to insert and fix the transducer module in the hearing aid housing by an automated technique.

In an embodiment of the hearing aid manufacturing method according to the invention, the transducer module is inserted into the hearing aid housing from below through an opening forming the sound outlet of the hearing aid housing. This is the preferred step, ie, the transducer module is housed in the receiving hole of the support beam plate, and then the support beam plate with the transducer module is moved relative to the hearing aid housing, and the sound outlet of the hearing aid housing is moved. It allows insertion from the forming end into the hearing aid housing. It is obvious to the expert that this step can easily be carried out by automated techniques. That is, the support beam plate is provided with a large number of storage holes, and a corresponding number of transducer modules are stored therein. The supporting beam plate thus containing a large number of transducer modules is then inserted from below into a corresponding number of hearing aid housings of the hearing aid to be manufactured.

In an embodiment of the method for manufacturing a hearing aid according to the invention, the support beam plate is connected to the hearing aid housing, preferably by gluing or welding, following the above steps, and then separated along the contour of the hearing aid housing. And is used as part of the hearing aid housing.

In a further embodiment of the method for manufacturing a hearing aid according to the invention, the receiving hole of the transducer module in the support beam plate is formed as a bag-shaped opening, and the bottom plate part below this bag-shaped opening is formed as the diaphragm described above. It In this case, this diaphragm is formed integrally with the supporting beam plate, or is formed by attaching a thin layer material to the supporting beam plate. Of course, when the bottom plate portion of the bag-shaped opening is used as a diaphragm as described above and is integrally formed with the supporting beam plate, the supporting beam plate is a material satisfying the requirements as a diaphragm material. , Preferably made of an elastic material such as latex or silicone rubber.
