Description

Technical field The invention relates to a system for audio processing and playback, consisting of a sound device and at least one external interface for contactless and / or wireless interaction, in particular for activation, transmission and playback of audio content. State of the art Known systems allow either: • Audio output via speakers • Streaming via wireless connections • or contactless activation of individual functions However, these systems are not capable of: • providing automated audio triggering through contactless interaction • simultaneously integrating recording, storage, and playback • providing a combination of structure-borne and airborne sound playback • or forming a closed system of trigger, content, and playback Object of the invention Providing a system that: • activates audio content through simple interaction • can record, save, and play back audio • combines streaming and local content • creates an immersive sound experience • is modular and expandable Solution of the invention The invention provides a system comprising: a) a sound device (“sentaboxx”) with: • housing • sound unit (airborne and / or structure-borne sound) • control unit • storage • recording and playback unit b) at least one interface: • contactless (e.g., NFC) • wireless (e.g., Bluetooth, WLAN) c) an interaction unit: • external device (smartphone) or • data carrier (NFC tag) Functionality (System Level) 1. An external signal (e.g., NFC) activates the system. 2. The sentaboxx recognizes the signal. 3. Audio content is automatically selected. 4. The content is: ◯ played from local storage OR ◯ streamed. 5. Optionally: o new audio content is recorded and saved. 6. Playback occurs: ◯ via airborne sound (side speaker) ◯ and / or structure-borne sound (exciter on the underside). Special system advantages • Combination of trigger + content + playback • Can be used without a user interface • Combination of local storage and streaming • Integrated recording function • Immersive sound transmission Other embodiments The system can be expanded by: • multiple sentaboxx devices (multiroom) • cloud connection • app control • personalized audio profiles • automatic audio selection based on context General note The drawings described below represent exemplary embodiments of the invention. Identical reference numerals denote identical or equivalently functioning elements. Figure 1 - Overall view of the device Fig. 1 shows a perspective view of the sound device (1) according to the invention in the form of the sentaboxx. The device comprises a housing (2), which is preferably cuboid in shape with rounded edges. An NFC interface (3) is located on the top of the housing (2), which is used for contactless activation of audio content. Figure 2 - Sectional view of the device Fig. 2 shows a partially cutaway view of the device (1), with the interior of the housing (2) visible. Inside, a control unit (5), in particular an electronic circuit board, is arranged. The device also includes a power supply (6), preferably in the form of a battery. The NFC interface (3) is located in the upper part of the housing (2) and is connected to the control unit (5). Figure 3 - NFC Interaction Fig. 3 shows the contactless activation of the device (1) using an external NFC-enabled device (8), for example a suitable sentatag or smartphone. When the external device (8) is brought close to the NFC interface (3), a signal is transmitted (9) which triggers the playback of audio content. Figure 4 - Application on contact surface Fig. 4 shows the device (1) in operation on a contact surface (10), for example a table top or a piece of furniture. An exciter loudspeaker (4) arranged on the underside of the device (1) transmits vibrations (11) to the contact surface (10), thereby transmitting structure-borne sound. Figure 5 - Underside and speaker arrangement Fig. 5 shows the underside of the device (1). Here is the exciter loudspeaker (4), which is directly coupled to the underside of the housing. Additionally, an airborne sound loudspeaker (7) is arranged on one side surface of the housing (2). The outer housing structure (12) can consist of a sound-permeable material, in particular textile or grid structure.
