  • Patent number: 11004438
    Abstract: A sound system with upfiring speakers and a redirecting baffle is shown and described. Upfiring speakers simulate overhead speakers by using a ceiling to reflect sound toward the listener from above the listener's head. However, in rooms with high ceilings, such reflection is not practical. The redirecting baffle is spaced apart from the upfiring speakers along a height axis and is oriented downward so that a surface normal to the baffle is neither parallel to nor perpendicular to the floor. By adjusting the angle of orientation, the location at which the reflected sound quality is best can be adjusted toward or away from the upfiring speakers. The system is particularly useful for in-store displays as many stores have ceiling heights that make sound reflection from an upfiring speaker impractical.

  • Patent number: 10812884
    Abstract: A speaker system broadly comprises a plurality of speaker assemblies each including a speaker housing, an input circuit, a low range speaker, and a higher-range speaker. The input circuit receives audio signals from a sound system or other controller and actively or passively sends the audio signals to the speakers. The low-range speaker is positioned in the upper section and the higher-range speaker is positioned in the lower section. Each speaker assembly is configured to be suspended from an elevated structure and spaced from the other speaker assemblies within a listening area with each speaker assembly generating low frequency soundwaves and higher-frequency soundwaves. This reduces or eliminates out-of-phase crossover frequency wave cancellation effects within the listening area. The speaker housings are compact while allowing the low-range speaker and higher-range speaker to effectively produce and project desired soundwaves from the suspended speaker housing into the listening area.

  • Patent number: 9813805
    Abstract: An apparatus for re-distributing acoustic energy. The apparatus comprises a first concave surface defined as a surface of revolution of a line or curve. This curve of revolution is rotated beyond 230 degrees and thus defines a rather small opening, which has advantages in the frequency response output. Additionally or alternatively, edges of the concave surface may be rounded to provide advantageous effects in the sound output.

  • Patent number: 9654880
    Abstract: A sound generator 30 includes a piezoelectric element 1, a vibrating body 3a, a reflection member 81, a reflection member 82, an opening 21, and an opening 22. The vibrating body 3a vibrates due to vibration of the piezoelectric element 1 and generates a sound. The reflection member 81 is disposed in a first direction from the vibrating body 3a so as to be inclined with respect to the vibrating body 3a. The reflection member 82 is disposed in a second direction, which is opposite to the first direction, from the vibrating body 3a so as to face the reflection member 81 with the vibrating body 3a therebetween and so as to be inclined with respect to the vibrating body 3a. The opening 21 faces in a third direction. The opening 22 faces in a fourth direction, which is different from the third direction.

  • Patent number: 9648440
    Abstract: Embodiments are directed to speakers and circuits that reflect sound off a ceiling to a listening location at a distance from a speaker. The reflected sound provides height cues to reproduce audio objects that have overhead audio components. The speaker comprises upward firing drivers to reflect sound off of the upper surface and represents a virtual height speaker. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The virtual height filter may be incorporated as part of a crossover circuit that separates the full band and sends high frequency sound to the upward-firing driver.

  • Patent number: 9641923
    Abstract: A reflector and an electronic system produce a diffuse way by creating time delays in accordance with a number sequence. An acoustical passive reflector incorporates a series of wells in its surface to transform an acoustical wave into a series of acoustical waves having a time difference based on a number sequence. The electronic signal conversion system converts a signal into a series of signals having a time difference based on a number sequence. This can be used in an audio speaker system having N×N array of speakers where N is an odd prime number, arranged to be driven by the electronic signal conversion system in which the signal is converted into a series of signals centered on the signal with at least one signal being timed to precede the signal and at least one signal to follow the signal and the signal being arranged to be sent to the central speaker in the N×N array.

  • Patent number: 9544681
    Abstract: An omni-directional acoustic deflector includes an acoustically reflective body having a truncated conical shape including a substantially conical outer surface, a top surface and a cone axis, the acoustically reflective body having an opening in the top surface centered on the cone axis. An acoustic absorber is disposed at the opening in the top surface. The deflector may also include at least one opening disposed along a circumference of the substantially conical outer surface at a cone radius associated with a pressure maximum of an acoustic resonance mode with an acoustic absorber at each such opening. Speaker systems employing the omni-directional acoustic deflector have an improved high frequency acoustic spectrum response regardless of the location of the listener with respect to the speaker system.
