Description

The invention relates to a microphone holder for attaching a shotgun microphone to a mobile device, in particular to a tablet computer or smartphone.

Mobile devices, such as smartphones, are often equipped with one or even several powerful cameras. A main camera is usually mounted on a side opposite the main display and a "selfie camera" is mounted on the side of the main display.

The quality of the audio recording with a microphone contained in the smartphone often can not keep up with the quality of the camera recordings. In particular, a special directional effect of the microphone is difficult to realize because of the cramped space, so unwanted with the audio recording many ambient noise to be recorded.

From the state of the art external microphones are known to improve the audio recording, which can be connected with a plug via a socket of the smartphone to the smartphone.

The plug for connecting an external microphone is usually attached directly to a microphone housing of the microphone. US 2013/0108059 A1 For example, shows a stereo microphone for plugging on a smartphone, in which a housing is firmly connected to the plug, so that the socket of the smartphone mechanically carries the microphone. The position of the socket on the smartphone thus determines the exact position of the microphone, which often leads to unfavorable results.

Therefore, it is also possible that an external microphone has a cable connected to the microphone housing with a plug. Here, the microphone is connected to the smartphone via the soft cable, so that the microphone must be held and aligned with one hand. As a result, however, the operation of the smartphone is difficult without the holding hand.

US 9,080,714 B2 therefore shows z. B. a clamping device for holding a smartphone. In addition, other such special mounts for the microphone are known, but usually at least partially obscure the display. Also, these brackets are often unwieldy and their application is associated with several assembly steps.

These disadvantages are exacerbated when a particularly suitable directional microphone is used to reduce environmental noise, which should have a certain length - preferably at least 5 cm - in the direction of the acoustic directivity for a good directivity.

It is the object of the present invention to provide a microphone holder for mounting a microphone on a mobile device, in particular on a tablet or smartphone, which allows a variable use of the microphone with ease of use.
