Description of the Related Art

The sound consists of pressure waves that can generate small deformations in the surface. When sound is generated on one side of a surface, pressure waves from the sound may strike the surface. The surface absorbs energy from the pressure waves, causing the surface to vibrate. As the surface vibrates, air on the opposite side of the surface absorbs the energy of the surface vibration. The absorbed energy causes the air molecules to vibrate, generating a pressure wave on the other side of the surface. These pressure waves propagate in space, transmitting sound on the other side of the surface. In this particular way, sound can propagate on the surface via surface resonance.

Resonance is a phenomenon in which a vibrating system or an external force drives another system to oscillate at a specific frequency with a large amplitude. The frequency at which the response amplitude is a relative maximum is referred to as the frequency of resonance or resonant frequency of the system. For example, an acoustic transducer may generate audio signals at various frequencies. When the acoustic transducer is placed on a surface, a mechanical connection may be established between the surface and the acoustic transducer. Thus, when the acoustic transducer produces sound, the acoustic transducer may vibrate the surface at a corresponding frequency. In particular, a surface may amplify the sound produced by an acoustic transducer if the frequency at which the acoustic transducer vibrates matches the resonant frequency of the surface.

Thus, depending on the material and geometric properties of the surface, sound at one or more frequencies may be transmitted more efficiently than sound at another frequency via and/or through the surface. The frequency that is transmitted more efficiently through the surface is referred to as the resonant frequency of the surface. Each surface may have one or more resonant frequencies. Understanding the resonant frequency of a surface can be helpful for a variety of applications. For example, sound insulation techniques may selectively suppress one or more resonant frequencies of a surface to reduce the amount of sound that can propagate on the surface via surface resonance.

Conventionally, to determine the resonant frequency of different surfaces, each surface is tested individually. Changes in surface material and geometry affect the resonant frequency of each surface. The frequencies most efficiently transmitted by each surface material and geometry can be classified to generate a look-up table of resonant frequencies for various types of surfaces.

One disadvantage of common techniques for determining the resonant frequency of a surface is that they do not accurately predict the shift in resonant frequency due to the manufacturing and construction process. In particular, inserting screws and holes in a surface can shift the resonant frequency of the surface greatly. Furthermore, fastening different types of surfaces to each other may change the resonant frequency of the two surfaces. Thus, the resonant frequency of a surface in isolation may be different from the resonant frequency of the same surface within a complex structure (such as a building). As a result, common techniques for determining the resonant frequency of a surface may be less effective in accurately predicting the resonant frequency of the surface after various manufacturing and construction processes.

As previously mentioned, there is a need for techniques for more efficiently determining the resonant frequency of a surface.

Disclosure of Invention

Embodiments of the present disclosure set forth a resonator apparatus for generating a resonance map of a surface. The resonator apparatus includes an actuator mechanism that vibrates the surface. The resonator apparatus also includes one or more sensors that detect deflection of the surface in response to the actuator mechanism vibrating the surface. The resonator apparatus also includes a processor. The processor is configured to generate the resonance map based on the detected deflections.

Other embodiments provide, among other things, a computer-readable medium and a method configured to implement the techniques set forth above.

At least one advantage of the techniques described herein is that the resonator device is able to determine the resonant frequency of the surface after the surface has been assembled. Thus, the resonator apparatus is able to detect the resonant frequency of the surface more accurately than the common technique of testing the resonant frequency of the surface just before the surface is included in the structure. In addition, the resonator device is movable and able to access surfaces that are difficult to reach and/or surfaces that are unsafe for human access located in parts of the structure. Thus, the resonator apparatus increases the number of surfaces that can be tested while improving the safety of the resonance test for the user. Finally, the resonator device can also implement a resonance diagram to vibrate the surface to produce sound. The generated sound can be used for a variety of purposes, such as noise cancellation and entertainment audio generation.
