Problems solved by technology

This document does not describe means for ensuring that the angular orientation of the ear pads relative to the earphones is always correct, and since the embodiments shown in this document use round earphones and similar earpads or square earphones and similar The angular orientation of the earpads on the headset is not addressed in the headset described in 9,332,337 B2
Furthermore, in this document, no means are disclosed for preventing, for example, the right earpad from being placed on the left earphone and the left earpad from being placed on the right earphone

Embodiment Construction

[0041] Hereinafter, a detailed description of example embodiments of the present invention is given. It should be understood, however, that the principles of the invention may be implemented in other ways.

[0042] refer to figure 1 , shows a schematic cross-sectional view of an earphone device according to the invention, generally designated by reference numeral 1 and comprising a loudspeaker housing 2 and an ear pad 3 according to an embodiment of the invention. The earpad 3 comprises an earpad body 4 attached to an earpad side part 5 in which a plurality of permanent magnets 9, 11 are arranged. exist figure 1 In the embodiment shown in (a), the polarity of the two magnets 9 , 11 shown in the figures is as shown, ie with a south pole facing the loudspeaker housing 2 . The opposite polarity of the magnets shown can also be used, as in figure 1 Magnets 18, 19, 20, 21 in (b) are shown. Thus, the opposing magnets 9, 10 and 11, 12 respectively attract each other and thus the...

Abstract

The present invention relates to an earphone device comprising a speaker housing having a speaker housing side portion and an ear pad having an ear pad side portion; the speaker housing side portion and the ear pad side portion are configured to be releasably connected to each other along an end surface of the ear pad side portion and an end surface of the speaker housing side portion; the speaker housing side portion includes a plurality of first permanent magnets each generating a magnetic field in a direction substantially perpendicular to an end surface of the speaker housing side portion; the ear pad side portion includes a plurality of second permanent magnets, each magnet generating a magnetic field in a direction substantially perpendicular to an end surface of the ear pad side portion; for each pair of first and second permanent magnets, the polarity of the magnetic field of the first permanent magnet is opposite to the polarity of the magnetic field of the second permanent magnet when the speaker housing side portion and the earpad side portion are aligned and contacted with each other. The invention also relates to an earphone comprising the earphone device.

Description

technical field [0001] The present invention relates generally to the field of earphones and earphone devices, and more particularly to means for ensuring that a correct combination of earphone speaker housing and ear pad is always obtained. Background technique [0002] In earphones (sometimes referred to as "earphones") comprising separate left and right earphone devices with corresponding earpads, the acoustic properties of the respective earphone devices depend on both the characteristics of the components of the earphone speaker housing (e.g., on the The performance of the electro-acoustic transducer, also known as the "speaker", and possibly the performance of acoustic and electronic signal processing devices, such as frequency response equalizers or active noise cancellation devices, in turn depends on the Acoustic properties of the ear pads at body time. In the case of high-quality sound reproduction via such headphones, it is important to always ensure the correct ...
