Description

1 TARIFF Audio module for handheld consoles TECHNICAL AREA 5 The invention relates to sound modules for handheld consoles in general. The invention is specifically designed to improve audio output and chat microphone quality for Steam. Developed for portable handheld consoles such as the Deck / ROG Ally class, it protects the handheld console from damage. Forward-facing on handheld consoles, which can be used as a detachable accessory without needing to be attached. A stereo soundstage resistant to slackening, while simultaneously suppressing fan / key noise. an anechoic and low-latency chat infrastructure without burdening the console processor with strokes. It relates to an audio module that provides sound. STATE OF THE ART There are various applications available for microphone solutions on handheld consoles. These include... for example, via the controller or headphone jack of a handheld console Microphones / headphones with a working 3.5 mm jack or USB output can be shown. Another 20 For example, dedicated gaming microphones that connect directly to the console via USB or a 3.5mm jack. Or they could be adapters. Extra audio interfaces with wireless or dongle support. also solutions for making more professional microphones compatible with the console using These solutions exist. The biggest problem with these solutions is the limited sound quality. Inexpensive headset microphones or microphones that plug directly into the console provide detailed sound. 25 It may not be sufficient for capturing or separating high levels of ambient noise. Compatibility is also important. Another problem that can be identified is compatibility. Latency and frequency. Technical problems such as band interference can occur. For example, in wireless systems. Signal interruption or interference may occur. In current technology, handheld consoles have speakers located inside the case, facing downwards or to the side. They are used. However, in handheld consoles with these types of speakers, the drivers are palm-sized. It can be partially covered by the inside, the table surface, or the case; consequently, the stereo The image narrows and the mid-to-high frequencies are damped. Single or double embedded in the fuselage. 2 In microphone applications, fan, trigger, and button sounds are located very close together. remaining; in this case, since directionality is low, the focus is on the player's mouth. It is becoming more difficult. Simple noise gates can cut off breaths and syllable beginnings. Internal external Bluetooth speakers / microphones developed as an alternative to these solutions Latency and synchronization issues, multi-device management, 5 This creates disadvantages such as battery and cable clutter. Software-based virtual In stereo expansion solutions, if the physical driver placement is insufficient, the soundstage is limited. It expands on paper; however, in practice, phase problems and thinning in the mid-frequencies occur. It is visible on the device's CPU (Central Processing Unit). Acoustic Echo Cancellation (AEC) or Beam 10 performed Beamforming applications are consumed by games and applications. It increases CPU / GPU (Graphics Processing Unit) resources and This can lead to a decrease in performance. As a result of research conducted under the known state of the art, US20240205587A1 15 Application number [number] was found. In the said application, for gaming headphones... The active noise cancellation system is explained. The aim here is to allow players to experience high-level noise cancellation. With background noise (e.g., tournament atmosphere, crowd sounds), only the game is played. The goal is to enable them to hear the voice and team chat clearly. Inside the headset... By adding feed-forward and feed-back microphones to speaker and microphone structures, 20 Algorithms for suppressing ambient noise are used; speech sound is also included. Masking (noise masking) is implemented along with the signal. The application is portable. Although it was developed as an accessory audio module for consoles, it is a physical Due to location and space limitations, the speakers and microphones could not be placed as desired. It cannot always guarantee that it will be positioned at the correct angle and with optimum performance. 25 The application includes a compact, forward-facing external mini soundbar and beamforming. The integration of the (beamforming) microphone module is not an option. Therefore, Because forward-facing audio and clear chat microphone performance could not be provided. The product's claim regarding user experience may be weakened. As a result, improvements are being made to the sound modules for handheld consoles. Therefore, it will eliminate the disadvantages mentioned above and improve existing systems. New structures are needed to provide solutions. 3 THE PURPOSE OF THE INVENTION The present invention meets the aforementioned requirements and overcomes all the disadvantages. with an audio module for handheld consoles that eliminates the need for a separate audio module and brings some additional advantages. It is related. 5 The main purpose of the invention is to improve sound output and chat microphone quality. Developed for portable handheld consoles such as the Steam Deck / ROG Ally class, the handheld console Can be used as a removable accessory without causing damage, facing forward on handheld consoles. 10 an anechoic and low-latency chat infrastructure without burdening the console processor with strokes. It provides an audio module. One purpose of the invention is to provide audio output and chat functionality on handheld consoles. The goal is to improve the microphone quality. 15 Another purpose of the invention is for games and applications that require a forward-facing stereo stage. online multiplayer that requires clean, echo-free speech in a fan / noise environment. The scenarios are what we aim for. Another purpose of the invention is to create a forward-facing, impact-resistant stereo system with palm-sized echo. The goal is to provide a cancellation-free online chat. The structural and characteristic features and all the advantages of the invention are given in the figures below.

Figure 1 shows an integrated handheld console (E) such as the Steam Deck / ROG Ally class. The invention, whose representative view is given, improves sound output and chat microphone quality. 20 detachable accessories for increasing power, without damaging the hand console (E). available on handheld consoles (E) with a forward-facing, slack-resistant stereo stage Simultaneously suppresses fan / key noise, and provides echo-free and low-latency chat. It is an audio module (M) that provides its infrastructure to the console processor without stroke loading. The subject of the invention is the sound module (M); 25  Forward-facing oval drivers producing stereo sound (1),  Connected behind the mentioned drivers (1), in phase with the drivers (1) By providing compatible air springing, it achieves low-frequency extension. producing fuller bass in a closed volume without excessive stroke overlay. a passive radiator (2) providing extended low-end response, 30  Palm / key / fan powered by a device that suppresses lateral sounds by creating a beam of light towards the mouth. an array of microphones that place response pits to their sources (3),  Driving the aforementioned microphone array (3), Game / application sounds Acoustic Echo Cancellation, beam direction, and directing light directly to the user. by running noise reduction processes internally, the handheld console a processor that processes sound without adding extra strokes to its processor (4),  Structural noise is eliminated by transferring vibration and body noise to the microphone. an isolator that reduces and prevents feedback (5) It includes 5. The subject of the invention is the sound module (M) facing the front of the handheld console, in a real, physical form. It creates a stereo soundstage and simultaneously filters the user's voice from fan / key noise. It purifies the sound and transmits it to the other side without echo. Thus, both game / application sounds are transmitted directly. It is directed towards the user (minimal interruption), and the chat sound is clear and understandable; 10 Since all these operations take place on the processor (4), game performance is not affected. The body of the sound module (M) will be aligned with the front edge of the handheld console. It is in the form of a rubber insulator (5), sound module (M) and hand console. By creating a vibration barrier between (E), the vibration transmitted to the body is reduced. and mechanical noise from hand contact passes less into the acoustic volume. Isolator (5), 15 It reduces structural noise that transmits body vibrations to the microphone; while in motion or When placed on the table, it reduces low-frequency hum and improves beam stability. increases. In a sample application of the invention, 20 located at each end of the sound module (M). drivers (1), efficient medium-low in a compact volume thanks to the large membrane area generates frequency. Passive radiators (2) connected to the rear of the drivers (1) are connected to the drivers (1) It provides low-frequency extension by delivering phase-coherent air spring action. This is for the palm of the hand. A richer sound is felt during use, and the tonality is balanced even at low levels. This means that the axes of the drivers (1) are facing directly towards the user, 25 major problems with closing / masking caused by palms and table surfaces It largely eliminates it. Stereo centering and in-game positional cues are more effective. It is perceived as consistent. Behind the front grille, a 4-microphone array (3) is placed at deliberate intervals from each other, 30 The geometry and sampling of the microphone array (4) are driven by the processor (4). The timing of the side lobe / pit is determined by the direction of the console's fan and grip position. This allows for their placement; thus reducing fan noise, button / joystick clicks, and finger movements. Near field sources such as friction are suppressed. The processor (4) digitally outputs the speaker output. 6 It runs an Acoustic Echo Cancellation loop that references a copy of the image. From the console. When the game / chat sound is emitted into the environment, the microphone signal contains the same content. Palm views, screen bezels, and room reflections are adapted and subtracted. This allows for... The signal going to the other side is almost exclusively the player's voice. Acoustic Echo Cancellation subsequently spectral noise reduction and AGC (Automatic Gain Control) Gain Control layers maintain speech consistency; high-pitched sounds like breath / “s” Dynamic de-esser (sibilance suppressor) is applied to the frequency components. Audio recording, In broadcasting or mixing processes, pointed consonants such as "s", "sh", "ch", and "z" The high-frequency, high-pitched pulses (sibilance) it produces are automatically detected and reduced. The processor (4) implements mild stereo widening and Dynamic Equalizer at low levels. 10 These operations are performed while maintaining phase accuracy and without shifting the sensory center. High at higher levels, multi-band compression is used for hearing safety and distortion protection. It activates; low frequency to prevent excessive stroke in passive radiator structure. The limits are adjusted adaptively. A fixed, low-latency one on the processor (4) The process is carried out in a chain; only the result signals are transmitted to the console. Thus, the game is 15 includes “lip-synchronization” and chat delay It is negligible; console CPU (Central Processing Unit) GPU (Graphics Processing Unit) resources are preserved.
