Electronic module having transducers radiating ultrasonic waves
An electronic module is provided. The electronic module includes a first transducer and a second transducer. The first transducer is configured to radiate a first ultrasonic wave. The second transducer is configured to radiate a second ultrasonic wave. The first transducer and the second transducer are disposed on noncoplanar surfaces.
1. An electronic module, comprising:
a substrate having a first surface and a second surface opposite to the first surface;
a set of transducers disposed adjacent to the first surface of the substrate, wherein the set of transducers are arranged in an array; and
an electronic component disposed adjacent to the second surface of the substrate and configured to control the set of transducers;
wherein the substrate comprises an adjustable substrate and the electronic module further comprising an encapsulant configured to support the adjustable substrate.
2. The electronic module of claim 1 , wherein the electronic component is configured to adjust at least one of a frequency, an amplitude, a phase, and an emission direction of ultrasonic waves radiated by the set of transducers.
3. The electronic module of claim 2 , wherein the electronic component comprises a storage device to store audio data/information to be transmitted through the set of transducers.
4. The electronic module of claim 1 , wherein the electronic component is aligned with the center of the array of the set of transducers.
5. The electronic module of claim 4 , wherein the set of transducers are arranged in a two-dimensional array.
6. The electronic module of claim 5 , wherein ultrasonic waves radiated by the set of transducers have substantially the same phase.
7. The electronic module of claim 6 , wherein a normal line of the electronic component is substantially aligned with a normal line of a transducer of the set of transducers located at the center of the array.
8. The electronic module of claim 1 , further comprising another electronic component configured to control at least another set of transducers.
9. The electronic module of claim 1 , wherein a shape of the encapsulant is defined based on a shape of the adjustable substrate after being adjusted.
10. The electronic module of claim 9 , wherein a lateral surface of the encapsulant is non-coplanar with a lateral surface of the adjustable substrate.
11. The electronic module of claim 1 , wherein the substrate comprises a flexible printed circuit (FPC).
