Definitions
- the present invention relates to a handset.
- earphones or headphones is typically a fixed adjustment of the acoustic properties of the listener. However, it is often desired by users that they themselves can change the acoustic settings of the listener.
- WO 97/00592 shows a headset with user adjustable acoustic properties.
- the handset has a housing with an electro-acoustic transducer.
- openings are provided on the ear-facing side. Further, an opening between the outer volume and the rear volume between the electroacoustic transducer and the housing and an opening between the rear volume and the front volume may be provided. By turning a setting element, these openings can either be completely closed or completely opened.
- a receiver is provided with at least one housing and at least one electroacoustic transducer having first and second surfaces.
- the handset further includes a first volume defined by the first surface of the electroacoustic transducer and by a first end of the housing and a second volume defined by the second surface of the electroacoustic transducer and by a second end of the housing. Between the first and second volumes, an opening is provided.
- a closing unit serves to at least partially close the opening.
- the clamping unit has a bass tube element and a rotatable cover unit, wherein the length of the bass tube is variable by rotating the cover unit.
- the invention relates to the idea of providing a receiver with a housing and an electroacoustic transducer disposed therein, wherein the transducer has a first and a second surface.
- the converter divides the housing into a first volume and a second volume.
- the first volume extends between the first surface of the transducer and the inside of the listener on the ear-facing side.
- the second volume is defined by the second surface of the transducer and by the housing facing away from the ear.
- an opening is further provided, which can be at least partially closed by a closing unit.
- the closing unit is designed such that it can change the opening degree continuously.
- a damping element is provided at the opening.
- the closing unit By opening or closing the closing unit, the acoustic resistance between the front and back of the transducer can be controlled, in particular the low-frequency properties can be controlled.
- the closing unit can be actuated by the user.
- the damping unit By providing the damping unit, the acoustic impedance of the bypass or the opening can be defined.
- the sound pressure within the transfer tube and the ear canal can be reduced or increased. If the clamping unit is open, then a low bass response can be realized. However, if the clamping unit is closed, then an increased bass response can be obtained.
- the closing unit can be implemented as a rotatable disk, by means of which the opening can be closed continuously.
- the opening can be at least partially closed by means of a rotary movement.
- Fig. 1 shows a schematic representation of a handset.
- the listener is designed in particular as an in-ear listener.
- the receiver has a housing 10 with a first ear-facing end 12 and a second end facing away from the ear 11.

- the electroacoustic transducer 20 is disposed between a first volume 100 and a second volume 200.
- An opening 300 connects the first to the second volume 100, 200.
- a closing unit 30 is provided to at least partially close the opening 300.
- the closing of the opening 300 can be carried out continuously, ie by means of the closing unit 30, the opening 300 can also be only partially closed or the opening degree of the opening can be adjusted.
- the closing unit 30 can be actuated by the user.
- a damping unit 400 may be provided in front of the opening 300.
- the first volume 100 is bounded by the first surface 21 of the electroacoustic transducer 20 and by the first end 12 of the housing.
- the second volume 200 is bounded by the second surface 22 of the electroacoustic transducer 20 and by the second end 11 of the housing.
- a baffle (with an electro-acoustic transducer) is provided between the first and second volumes, which has a closing unit 30 in order to at least partially close an opening or a bypass 300.
- the acoustic resistance between the first and second volumes 100, 200 can be increased.
- the closing unit By moving the closing unit, the acoustic resistance can be reduced.
- an increased extinction in the low-frequency range may occur and the reproduced frequency response may be lower bass.
- the user or the user has the ability to change the playback characteristics of the listener.
- no electronic components are needed, since this can be implemented, for example, by a closing unit 30.
- the closing unit 30 can be realized for example by a slider.
- the closing unit can be designed such that the opening can be at least partially closed by means of a rotary movement.
- Fig. 2 shows a graph of a frequency response of the listener of Fig. 1 , In Fig. 2 four frequency responses are shown.
- the frequency responses 1 and 2 represent the frequency responses with closed or open bypass 300. Especially in the range between 100 and 300 Hz, the differences between open and closed bypass can be seen.
- Frequency responses 3 and 4 also represent the frequency responses for closed and opened bypass.
- a headset is provided, which is based on the handset according to the first embodiment.
- Fig. 3 shows a perspective view of a part of a handset according to the first embodiment.
- a capsule holder 50 and a closing unit 30 are shown.
- the capsule holder has a first end 51 and a second end 52 with a hole 53.
- the first end 51 of the capsule holder 50 serves to receive an earphone capsule and at the second end 52, the closing unit 30 is provided.
- the closing unit 30 can have a screw 31, a first element or a cover element 32, a second element or a bass tube element 33, a housing 34 and optionally a spring 36 between the housing 34 and the cover element 32.
- Fig. 4 shows a schematic sectional view of the part of the handset according to the first embodiment of Fig. 3 ,
- the capsule holder 50 is shown with the first end 51 and the second end 52, wherein in the second end 52, an opening or a hole 53 is provided.
- the closing unit 30 is shown.
- the closing unit 30 has a screw 31, a first element or a cover element 32, a second element 33 or a bass tube element 33, a housing 34 and optionally a spring 36. Further, an x and a y axis are shown.
