Embodiments disclosed herein generally relate to a system and method for centrally controlling the audio output on one or more gaming machines in a casino gaming system.
Gaming machines have been developed with various components and features to enhance the gaming experience for casino patrons. For example, gaming machines include audio systems that provide music and sound effects to intensify the gaming experience by supplementing the visual effects of the gaming machine. Generally, these gaming machines may have audio systems that include one or more speakers, an amplifier, and a volume control.
Currently, gaming establishments control the audio levels of the individual gaming machines by manually adjusting the volume control in each gaming machine. This is a labor-intensive and inefficient process, especially for gaming establishments having thousands of gaming machines. Furthermore, this process is subject to human error because the volume controls are generally ungraduated volume knobs.
Furthermore, these audio systems are limited in the sound effects that may be provided by the gaming machine. That is, the gaming machine is only capable of producing those sound effects stored within the gaming machine. Additionally, the gaming machine is only capable of outputting the sound effects at pre-determined times or upon the occurrence of a predetermined event. Thus, the gaming machine is the sole arbiter of its sound effects, thereby making it difficult to change the sound output.
What is needed is a system and method that allows for the centralized control of audio output on a gaming device through a backend system. More particularly, what is needed is a system and method that allows for the uniform and simultaneous adjustment of multiple gaming machine volume levels, as well as audio effects triggered by the backend system.
Briefly, and in general terms, various embodiments for controlling the audio output of one or more gaming machines from a central location are disclosed herein. One embodiment is directed to a system comprising one or more microphones positioned in a casino gaming floor environment to obtain noise level data. The system also includes a system server connected to the one or more microphones to receive the obtained noise level data and to determine the appropriate audio output for one or more gaming machines. The system also includes an audio hub positioned within each gaming machine and connected to the system server, wherein each audio hub receives audio instructions from the system server and adjusts the audio output for one or more gaming machines.
In another embodiment, the system comprises one or more noise level detectors positioned in a casino gaming floor environment to obtain noise level data. A microphone interface is connected to each of the one or more noise level detectors, wherein the microphone interface monitors the casino noise levels. The system server is connected to the microphone interface to receive the obtained noise level data and to determine the appropriate audio output for one or more gaming machines. The system also includes an audio hub positioned within each gaming machine and connected to the system server, wherein each audio hub receives audio instructions from the system server and adjusts the audio output for one or more gaming machines.
Methods for centrally controlling the audio output of one or more gaming machines in a casino game networking system are also disclosed herein. According to one method, noise level data is captured from a casino gaming floor. The captured noise level data is analyzed and the appropriate audio output for one or more gaming machines is determined. Instructions for adjusting the audio output are then sent to one or more gaming machines.
These and other features and advantages will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate by way of example, the features of various embodiments.
Various embodiments are directed to a system and method for centralizing the control of the audio output for one or more gaming machines. More particularly, the system provides a central location from which the sound levels of multiple gaming machines may be adjusted. For example, the system permits the audio levels on one or more gaming machines to be uniformly raised on a slow night to give the perception of a busy casino. Alternatively, the audio levels on one or more gaming machines may also be uniformly lowered. The centralized audio control system assists customers by allowing the casino to easily control the audio output. For example, on a busy night, the volume level may be simply adjusted so that cocktail waitresses and bartenders can hear customers. Alternatively, on a busy night, the volume may be increased so the casino patrons can better hear the games offered for play on the gaming machines. Additionally, the centralized audio control system allows the casino to simultaneously mute the audio output of multiple gaming machines during an emergency situation or, alternatively, allows the gaming machine to play an emergency message. Furthermore, the centralized audio control system provides for the creation of audio sound effects and sound types that may be played on the gaming machines. Accordingly, casino operators have the ability to alter the songs, melodies, sound effects, and various sound types emanating from multiple gaming machines.
Referring now to the drawings, wherein like reference numerals denote like or corresponding parts throughout the drawings and, more particularly to

The noise level detector 52 obtains noise level data from the casino gaming floor and/or surrounding areas. More particularly, in one embodiment, the noise level detector 52 monitors the ambient noise level, or the constant level of noise, on the casino gaming floor. The ambient noise on a casino floor includes, but is not limited to, the interaction of customers and employees, media presentations (such as the sound emitted from bar television sets and performers), and the chatter of gaming devices either luring players to them or encouraging them to stay and play.
In one embodiment, the noise level detector 52 comprises one or more microphones 54 strategically placed around the casino gaming area to capture noise level data. One or more microphones 54 may be positioned at or near the ceiling, on the floor, against a wall, and/or on a gaming machine. Alternatively, the microphones 54 may be placed within, or among, a bank of gaming machines. As those skilled in the art will appreciate, the microphones 54 may be placed anywhere on the casino gaming floor. As those skilled in the art will appreciate, a variety of microphones may be used in the centralized audio control system 10.

Optionally, in another embodiment, the microphone interface 56 is operatively connected to an ambient interface 58. The ambient interface 58 is capable of monitoring and averaging the casino noise level. The ambient interface 58 may also be capable of processing and analyzing the collected noise level data. For example, the ambient interface 58 may apply normalizing techniques to the collected data to average the noise level data. As those skilled in the art will appreciate other signal-processing procedures may be applied to the data. After processing the noise level data, the ambient interface 58 may send the resulting data to the system server 12. Alternatively, the microphone interface 56 may bypass the processing of the collected noise level data, and may instead send raw noise level data to the system server 12 for processing. Optionally, in another embodiment, both the ambient interface 58 and the system server 12 apply processing techniques to the collected noise level data.
Alternatively, in another embodiment, the microphone interface 56 is a sophisticated device comprising at least one processor and software for monitoring noise levels. The sophisticated microphone interface 56 is capable of collecting noise level data, analyzing the collected data and normalizing the collected data. In addition, the microphone interface 56 may include a sound processor for performing further detailed analysis of the collected data and as well as more processing of the collected noise level data. The collected noise level data is then sent to the system server 12. Optionally, in another embodiment, the noise level data is not processed or analyzed by the microphone interface 56 and is instead sent to the system server 12 for processing.
Once the system server 12 receives the noise level data, it analyzes the data and determines an appropriate audio output for one or more of the gaming machines 24 connected to the casino gaming network. The appropriate audio output is based on a set of pre-determined rules established by the casino or manufacturer. These pre-determined rules may vary between casinos. Furthermore, casino operators are able to specify or alter the audio output rules. For example, the casino may want gaming machine volume levels to be louder in the morning and quieter in the evening. Alternatively, the casino may want gaming machine audio levels to be at a particular volume during peak hours and at a different volume during off-peak hours. Additionally, the casino can set minimum and maximum audio levels for the gaming machines 24. Alternatively, the casino may establish audio rules for individual gaming machines and optionally, the casino may establish rules for subsets of gaming machines. Specifically, the casino can organize gaming machines into subsets according to their physical placement on the casino floor. Different subsets may have a different set of rules. For example, a subset of gaming machines located near the bar may have a first set of audio rules, while a subset of gaming machines located near the stage may have a second set of rules. Factors such as gaming machine placement, patron traffic, and machine usage may affect the desired audio level of the gaming machines.
The appropriate audio output may relate to not only volume levels but also sound types, such as but not limited to, music, melodies, sound effects, spoken-words, and the like. For example, the system server 12 may determine the appropriate volume level for one or more gaming machines 24. Additionally, the system server 12 may determine the appropriate type of sound for the gaming machine 24 to output from its speakers 64. Various sound files may be stored on the gaming machine 24, the game monitoring unit (GMU) (not shown) or the system server 12. The system server 12 can send instructions pertaining to sound type and storage location of a particular sound file.
In another embodiment, the system server 12 may send one or more sounds files to a plurality of gaming machines. The sound files may be the same sound file or different sound files. In one embodiment, the different sounds files are related so that a group of gaming machines may produce a Doppler sound effect. That is, the system server 12 may send sequential sound files to adjacent gaming machines in order to produce a Doppler sound effect among a bank of gaming machines. Alternatively, a sound file may be sent to one gaming machine to produce a Doppler sound effect on the machine.
Referring back to
In one embodiment, the audio hub 62 may include a switch to manually control the volume of the audio output in the event the system server 12 is not operational. According to one embodiment, the audio output may be manually controlled with a graduated volume knob. Alternatively, a digital display may be included with the volume knob wherein the display shows the volume level in decibels or other audio measurement units. In yet another embodiment, the audio hub 62 may be operatively connected to other system components including by way of example, but not by way of limitation, a game management unit (GMU) (not shown). Accordingly, the audio output of one or more gaming machines 24 may be controlled by the GMU should the system server 12 become inoperable.
According to one embodiment, the audio hub 62 is operatively connected to an amplifier (not shown). In another embodiment, the amplifier may be integrated into the audio hub. In other embodiments, the audio hub 62 may be operatively connected to other audio components such as, but not limited to, an equalizer, mixer, and the like.
In one embodiment, the speakers 64 are coupled to the audio hub via an amplifier. Alternatively, speakers 64 may be self-amplified. Optionally, the speakers 64 may be component speakers with separate tweeter, midrange, and subwoofer to provide better sound imaging to the gaming machine patron. In yet another embodiment, the speakers 64 may be full range speakers (e.g., two-way, three-way, or four-way speakers).
