[0025] exist figure 1 An electronic device 1 is shown in , which includes a housing 13 and a speaker 6 installed in the housing 13 . It has a first embodiment of a sound-directing element 3 which moves between a first position 5 and a second position 12 in which the element does not cover at least part of the loudspeaker 6 ; In this second position 12, at least part of the speaker is covered, and the sound emitted by the speaker 6 is tuned in one direction and redirected in another direction.

[0026] In the first position 5 the loudspeaker 6 is exposed through a recess 8 or at least covers a small hole 10 in the cover part 9 in the housing 2 . The housing 2 comprises at least one sound-directing part 3 with at least one sound channel 7 and at least one small hole 4 . Via 7 can also be installed in whole or in part in the corresponding position of electronic device 1 and housing 2 and / or in housing 13 inside housing 2 .

Abstract

In an electronic apparatus comprising a housing and loud speaker (6, 19, 27, 29, 47) mounted in the housing, a sound directing element (3, 14, 30, 38, 49, 56) is provided for movement between a first position in which the element covers at least part of the loud speaker sound generated by the loud speaker (6, 19, 27, 29, 47) being toned in one direction and redirected in another direction, and a second position in which said at least part of the loud speaker is uncovered.

Description

technical field [0001] The present invention relates to an electronic device, which includes a housing and a loudspeaker installed in the housing, in particular to an electronic device with a sound directing device. Background technique [0002] A user of a mobile phone listens by placing a speaker or earbuds close to his ear. Therefore, the sound from the speaker should be low enough so as not to cause damage to the user's hearing. Some mobile phones have a Private Mobile Radio (PMR) feature that emits a high sound level in the speaker when the PMR is activated, for example during a call, so that the user can hear the call from a distance call. In this particular mode, it is not possible to place the speakers close to the user's ears because the sound is too loud. [0003] There are some prior art devices that address the problem of varying the level of sound emitted by the loudspeaker in order to prevent damage to the user's hearing. A known solution provides two louds...
