Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speakers emit acoustic waves to the rear surface, then touch sensation is generated through the actuator, but the acoustic sound quality may be compromised
Solution Approach 1:
The speaker system is divided into two independent pathways: one for acoustic sound emission (front surface) and another for touch sensation generation (rear surface). The acoustic wave generated by the speaker is segmented into two directions, with the rear surface wave directed to the actuator through the movement passage, while the front surface wave provides audio output.
Solution Approach 2:
The movement passage filled with gas, liquid, or gel acts as an intermediary medium to transmit acoustic waves from the speaker to the actuator. This intermediary enables efficient energy transfer while maintaining independent control over acoustic and haptic functions.
2Adaptability or versatility
If separate signal separation devices are used to control acoustic and haptic outputs, then independent frequency and amplitude adjustments are achieved, but device complexity increases
Solution Approach 1:
The single speaker serves multiple functions: generating acoustic waves for audio output through the front surface and generating acoustic waves for haptic feedback through the rear surface. This multi-functional design eliminates the need for separate signal separation devices while maintaining independent control capabilities.
Solution Approach 2:
The speaker system self-services by generating the acoustic waves needed for both acoustic and haptic functions. The acoustic wave generated by the speaker naturally divides into two directions, with each pathway independently controllable through the existing speaker control mechanisms, without requiring additional signal separation hardware.
3Reliability
If the movement passage is filled with gas, liquid, or gel, then acoustic wave transmission efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The system allows parameter changes in the movement passage medium (gas, liquid, or gel) to optimize acoustic wave transmission efficiency. Different mediums can be selected based on specific application requirements, with each offering different transmission characteristics that can be tuned to achieve optimal performance.

The device achieves a sophisticated and realistic user interface by simultaneously generating acoustic sound and touch sensations, reducing power consumption through a simple driving circuit and maximizing touch sensation responses without the need for additional signal separation devices.
Implementation Method 1
an acoustic wave emitted to a lower portion of each of the speakers is transmitted to the pressure collecting part through the movement passages
Implementation Method 2
a plurality of movement passages each extending from a lower portion of each of the speakers along the inside of the lower frame between the speakers; a pressure collecting part disposed between the speakers
Implementation Method 3
an actuator connected to the pressure collecting part, and an acoustic wave emitted to a lower portion of each of the speakers is transmitted to the pressure collecting part through the movement passages
Implementation Method 4
the speakers generate a sound, and the actuator may generate a touch sensation to a user through a vibration transmitted from the pressure collecting part
Implementation Method 5
the vibration plate may vibrate air in the chamber by the acoustic wave emitted in the upward direction
Implementation Method 6
the speaker holes may amplify an acoustic wave emitted to an upper portion of the speaker and generate a sound to the outside
