Embodiment Construction

[0056] Figures 1a and 1b show that a detection device 20 (see figure 2 ) to find Example 10 of the hearing aid. The hearing aid 10 comprises the following parts: one or more input transducers (eg microphones) 1 , an electronic module 2 , and one or more output transducers (eg receivers) 3 . Alternatively or in addition, the hearing aid 10 includes a wireless receiver for receiving electrical signals including control and / or audio signals (and possibly including a wireless receiver for enabling selection of one of the input signals including audio or a mix of input signals from the input transducers). signal selection or mixing unit). The output transducer may for example comprise a mechanical vibrator, such as is associated with bone anchored hearing aids.

[0057] The electronic module 2 comprises at least an integrated circuit (IC) 4 and a tuned antenna circuit comprising a loss resistor 9 , a capacitor 12 and an inductance 11 . In an embodiment, one or more of the loss r...

Abstract

The disclosure describes a hearing aid and a detection device. The hearing aid comprises a control unit and an antenna circuit that are part of a wireless unit for wireless transmission and / or reception of electromagnetic signals. The antenna circuit comprises a capacitance and an inductance that together define a resonance frequency of the antenna circuit. The hearing aid further comprises a dissipative resistance and a switch. The dissipative resistance and the switch are arranged to allow selective coupling or decoupling of the dissipative resistance to or from, respectively, the antenna circuit to thus allow controlling of the dissipative properties of the antenna circuit by means of the switch. If the dissipative resistance is coupled with or connected to the antenna circuit, it dissipates some of the energy of the antenna circuit. If the dissipative resistance is decoupled or disconnected from the antenna circuit, the dissipative resistance is ineffective. The switch allows for selective coupling or decoupling of the resistance to the antenna circuit.

Description

technical field [0001] The invention relates to a hearing aid (or a part of a hearing aid) and a detection device therefor. Background technique [0002] Hearing aids are small devices worn by the user that help the user hear spoken words or other sounds. To improve the user's perception of sound, hearing aids include at least one microphone for receiving and converting acoustic signals into electrical signals (or other input transducers for receiving electrical signals including audio). These electrical signals are processed and, if necessary, amplified. The processed and amplified electrical signal is fed to the speaker and converted into an acoustic signal that is heard by the user's ear. The loudspeaker of a hearing aid is often referred to as a "receiver", although it is not a receiver in the literal sense (in the context of hearing aids, the term "receiver" is used in the same way as it is traditionally used in the field of telephony, meaning to convert an electrical...
