Description

receiver

The present invention relates to a listener.

In headphones, such as in-ear headphones, earphones or headphones typically a fixed setting of the acoustic properties of the handset takes place. However, it is often desired by users that they can even change the view acoustic settings of the listener.

WO 97/00592 shows a headset with adjustable by the user acoustic properties. The receiver in this case has a housing with a elektroakus- tables converter. In the housing openings on the side facing the ear side are provided. Further, an opening between the outer volume and the back volume between the electroacoustic transducer and the housing, and an opening between the rear volume and the front volume may be provided. By turning an adjusting these openings can be either completely closed or completely open.

It is therefore an object of the present invention to provide a receiver which allows an improved adjustment of the acoustic properties of the handset.

This object is achieved by a receiver according to claim. 1

There is at least one housing and at least one elec- roakustischen converter provided with a first and second surface of a listener. Of the

Earphone further comprises a first volume which is defined by the first surface of the electro-acoustic transducer and through a first end of the housing, and a second volume that is defined by the second surface of the electro-acoustic transducer and through a second end of the housing. Between the first and the second volume is an opening. A closing unit serves to close the opening at least partially.

The invention relates to the concept of providing a listener with a housing and disposed therein electro-acoustic transducer, said transducer having a first and a second surface. By the transducer, the housing is divided into a first and into a second volume. The first volume extends between the first surface of the transducer and the inner side of the listener on the ear-facing side. The second volume is defined by the second surface of the transducer and by the facing away from the ear housing. Between the first and second volume, an opening is also provided, which can be at least partially closed by a clamping unit. The clamping unit is configured such that it can dration change Öff- continuously.

According to one aspect of the invention, a damping element at the opening is provided.

By opening or closing of the clamping unit of the acoustic resistance between the front and back of the converter can be controlled, and in particular to the low-frequency characteristics are controlled. The clamping unit can be operated by the user. By providing the damping unit, the acoustic impedance of the bypass or the opening can be defined. Depending on the position of the closing unit of the sound pressure inside the transfer tube and the ear canal can be reduced or increased. When the closing unit is open, a low bass response can be realized. However, when the closing unit is closed, an enlarged bass response can be obtained.

The clamping unit can be used as a slide or alternatively be implemented as a rotatable disc, by means of which the opening can be continuously closed. The opening can be closed at least partially by means of a rotational movement.

Other aspects of the invention are the subject of the dependent claims.

Embodiments and advantages of the invention will be explained in more detail below with reference to the drawings.

The handset has a housing 10 with a first end facing the ear 12 and a second end remote from ear 1. 1 The handset further includes an electroacoustic transducer 20 having a first surface 21 and a second surface 22nd The elektroakus- tische Wandler 20 is arranged between a first volume and a second volume 100 200th An opening 300 connects the first to the second volume 100, 200. A locking unit 30 is provided to 300 for closing the opening at least partially. The closing of the opening 300 may be continuous while, ie by means of the closing unit 30, the opening 300 can be also closed only partially, or the opening degree of opening can be adjusted. The clamping unit 30 can then be actuated by the user.

Optionally a damping unit can be provided before the opening 400 300th The first volume 100 is bounded by the first surface 21 of the electroacoustic transducer 20 and through the first end 12 of the housing. The second volume 200 is limited by the second surface 22 of the electroacoustic transducer 20 and see through the second end 1 1 of the housing.

Thus, a baffle is (with an electro-acoustic transducer) provided between the first and second volume, which has a closing unit 30, to thereby close an opening or a bypass 300 at least partially. Thus, the acoustic resistance between the first and second volume 100 can be increased 200th By moving the closing unit of the acoustic resistance can be reduced. Thus, an increased extinction occur in the low frequency range and the reproduced frequency range may be bass poorer.

The inventive receiver of the user or the user has the option of reproduction characteristics of the listener to change. These no electronic components are needed, as this can be implemented for example by a clamping unit 30th The clamping unit 30 may be realized for example by a pusher. Alternatively or additionally, the closing unit can be designed such that the opening means of a rotational movement can be closed at least partially. Fig. 2 shows a graph of a frequency response of the earphone according to the first embodiment. In FIG. 2, four frequency responses are shown. The frequency responses 1 and 2 illustrate the frequency responses is in closed or open bypass 300th particular in the range between 100 and 300 Hz, the differences between open and closed bypass can be seen.
