AI Technical Summary
Existing loudspeakers, especially tabletop speakers, struggle to provide high-quality sound reproduction, particularly in low frequencies, due to their small size, which limits their ability to create a spatial sound impression and immersive gaming experience, while larger speakers occupy valuable space on the table.
A loudspeaker box design with a split chassis unit and bass body, featuring a sound channel and anti-slip pads, allowing suspension from a support element, maintaining a large cabinet volume while minimizing tabletop space.
The design enables high-quality sound reproduction with improved spatial sound impression and reduced vibration transmission, enhancing the gaming experience without occupying excessive table space.

Abstract
Description
[0001] The invention relates to a loudspeaker housing.
[0002] The loudspeakers are permanently attached to the loudspeaker enclosure. It is irrelevant whether the loudspeakers are located inside the enclosure or with their diaphragms facing outwards. The loudspeaker enclosure, also simply called the housing, can be airtight or open.
[0003] Loudspeaker cabinets need large enclosures for bass reproduction, so that low tones can be reproduced efficiently and cleanly. The air volume inside the enclosure acts like an air spring against the speaker diaphragm, and a larger volume means less acoustic resistance, allowing the speaker diaphragm to vibrate more freely and thus achieve a lower cutoff frequency.
[0004] The size of the enclosure has a direct influence on the frequency response and plays a crucial role in reducing acoustic short circuits.
[0005] Modern computer games and high-resolution audio files demand high-quality sound reproduction with the most linear frequency response possible and good depth perception. Depth perception describes the loudspeaker's ability to create a spatial sound impression, so that the auditory perception conveys the illusion of a three-dimensional stage. The user perceives different sounds from the sound source not only to the left and right, but also from the front and rear. Depth perception thus contributes significantly to acoustic orientation. For example, computer gamers receive important information about their environment based on sound, such as the position of opponents, teammates, or the proximity of dangers. Music and sound effects create emotions and strengthen the connection to the story and the characters.In competitive games, good sound helps players better understand sounds and react more quickly, thus gaining an advantage. Therefore, good sound is an essential component of an immersive and successful gaming experience. The positioning of the sound source in the near field relative to the listener is crucial. "Near field" refers to the spatial proximity of the sound source to the user's ear.
[0006] Many computer gamers use headphones to better experience the localization of in-game events. However, wearing headphones can lead to loud sound levels, which can cause irreparable hearing damage.
[0007] Also well-known are so-called tabletop speakers. These are sized so that they can easily be placed on a table near the player. Due to their small size and the resulting relatively small cabinet volume, these speakers offer a limited listening experience. In particular, the lower frequencies cannot be reproduced with the desired quality because of the speaker's small size.
[0008] In contrast, loudspeakers that provide the desired sound in the user's immediate vicinity are quite large in size and take up a corresponding amount of space on the table, which regularly contains one or more monitors and computer input devices.
[0009] The invention is based on the objective of designing a loudspeaker box in such a way that it occupies relatively little space above the tabletop despite having a large cabinet volume.
[0010] The problem is solved by a loudspeaker box according to the invention.
[0011] Fig. Figure 1 shows the loudspeaker enclosure, divided into two sections: an upper section, also called the loudspeaker chassis unit (1), and a lower section, called the bass body (2). The loudspeaker chassis unit (1) can accommodate one or more loudspeakers (10), and loudspeakers (10) can also be located in or on the bass body (2). Fig. 2) be provided for.
[0012] Due to the spatial design of the loudspeaker box, the components forming the space of the loudspeaker box have an inner and an outer side.
[0013] The inner side, also called the inner wall, faces the inside of the speaker housing, while the outer side, also called the outer wall, is visible from the outside.
[0014] The recess is formed by the sound rear wall of the loudspeaker chassis unit (4), the top cover of the bass body (5) and the recessed front plate of the rear (6).
[0015] Between the inner end plate of the rear (6) and the inner end plate of the front (7) and laterally limited by the inner walls of the cheeks (8) a sound channel (3) is created which spatially connects the loudspeaker chassis unit (1) and the bass body (2).
[0016] In further detail ( Fig. 2) the sound channel (3) is formed from the inner end plate of the front (7) and the inner wall of the curved cheek (8a).
[0017] The recess is dimensioned in its clear height so that the loudspeaker box can be suspended in a support element (11), for example a table top or a shelf.
[0018] If the loudspeaker box is hung in a support element ( Fig. 3), the loudspeaker chassis unit (1) is located above, the bass body (2) below the support element (11).
[0019] In a preferred embodiment, anti-slip pads are attached to the outside of the sound-reflecting rear wall of the loudspeaker chassis unit (4). These can also have a damping effect, so that less vibration is transmitted from the loudspeaker box to the load-bearing surface (11). List of identifiers: 1. Speaker chassis unit 2. Bass body 3.
