Sound box capable of adjusting sound effect automatically as environment change and adjusting method thereof

Abstract

The related sound box, which can automatic tune sound effect as the environmental varies, comprises: a distance parameter input device to collect and obtain the distance between box and reference, a processor to calculate the action command for adjusting horn angle and control the next controller for rotating to the specified angle, a horn angular controller, and a rotatable horn assembly. This invention introduces much convenience to sound box application.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a sound box capable of automatically adjusting sound effects according to environmental changes and an adjustment method thereof. Background technique [0002] With the popularization of home theater audio, there are various styles of surround speakers on the market. The so-called surround speakers are designed to achieve surround sound effects based on the different locations of the surround speakers. In this way, the original sound can be reproduced, making it easier to use. Those who have the feeling of being there. The commonly used surround sound system uses independent speakers of left and right front speakers, left and right rear speakers, center speakers and subwoofer speakers to be arranged in different positions of the building. Generally, an ideal listening effect can be achieved within the preset distance (space), but the requirements for the placement of the spe...

Problems solved by technology

The commonly used surround sound system uses independent speakers of left and right front speakers, left and right rear speakers, center speakers and subwoofer speakers to be arranged in different positions of the building. Generally, an ideal listening effect can be achieved within the preset distance (space), but the requirements for the placement of the speakers are relatively strict, otherwise it will be difficult to truly realize the surround sound effect, and if the speakers are arranged according to the above requirements, it will inevitably affect the The indoor environment, decoration and space put forward strict tests, so consumers must also face consideration and analysis of home design issues when purchasing, which brings great inconvenience

[0003] Today, with the continuous development of electro-acoustic technology, audio technology is advancing by leaps and bounds, and the appearance of integrated multi-channel surround speakers can save space in the house and avoid confusion in the direction of speakers, such as Chinese patents CN2631173Y, CN2826877Y, and CN2824486Y; Taking the Chinese patent CN2631173Y as an example for illustration, this patent document discloses a multi-channel surround speaker, which is equipped with a main speaker and a surround speaker on the surface of a single speaker capable of accommodating several speakers. The surfaces of the above-mentioned speakers are provided with different inclined surfaces for placing several surround speakers, so that the direction of sound emission of these surround speakers is different from that of the main speaker, so that the sound waves can be continuously refracted by the walls of the room to achieve the effect of surround sound, so that it can be matched with the interior of the house. However, it is also because the angle of the speaker is fixed, only when the speaker is placed in the right position, that is, the distance parameter between the speaker and the wall and other media involved in refraction falls within the preset distance ( Better surround sound effects can be achieved within the range of the preset distance (space). Once the preset distance (space) range is exceeded, the listening effect will be greatly reduced. Therefore, the specific position of the speaker will directly affect its surround sound effect. In this case, it still needs to rely on the special surrounding environment in the house to arrange the speakers reasonably, which is not conducive to product competitiveness.
