Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile terminal integrates heat source components like CPUs and batteries to provide diverse functions, then the functionality and performance are improved, but heat generation increases and heat dissipation becomes difficult
Solution Approach 1:
The patent combines the fan function with the speaker box by integrating the speaker unit into the housing body and using the speaker box's air inlet and air outlet structures to form a heat dissipation channel. The fan blade is disposed in the air inlet of the speaker box, merging cooling functionality into the existing audio component structure.
Solution Approach 2:
The speaker box structure serves dual purposes: it functions as both an audio output device and a heat dissipation system. The air inlet and air outlet of the speaker box are utilized for both speaker operation and creating airflow for cooling internal components.
2Volume of moving object
If the mobile terminal is made compact with small internal space, then portability is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The fan blade is disposed within the air inlet of the speaker box, nesting the cooling component inside the existing speaker structure. The heat dissipation channel is formed by utilizing the internal space of the housing body and speaker box, nesting multiple functions within a compact volume.
Solution Approach 2:
The patent creates a three-dimensional heat dissipation pathway by forming a heat dissipation channel that extends from the air inlet through the housing body to the air outlet. The speaker box is positioned to create vertical and horizontal airflow paths, utilizing spatial dimensions efficiently within the compact device.
3Temperature
If a traditional separate fan structure is used for heat dissipation, then cooling effectiveness is improved, but device complexity and space occupation increase
Solution Approach 1:
The fan function is merged with the speaker box by integrating the speaker unit into the housing body and using the speaker box's air inlet and air outlet structures to form a heat dissipation channel. The fan blade is disposed in the air inlet of the speaker box, merging cooling functionality into the existing audio component structure.
Solution Approach 2:
The speaker box structure serves dual purposes: it functions as both an audio output device and a heat dissipation system. The air inlet and air outlet of the speaker box are utilized for both speaker operation and creating airflow for cooling internal components.

AI summary
The invention relates to a sounding device having a first housing body with a first accommodation space, and a speaker box accommodated into the first housing body. The speaker box includes a second housing body with a second accommodation space, and a speaker unit accommodated in the second housing body. The speaker unit divides the second accommodation space into a front acoustic cavity. The sounding device further comprises a one-way intake valve. The speaker box, serving as a fan in a mobile terminal, pushes air circulation inside and outside the mobile terminal, thereby achieving a heat dissipation effect and facilitating internal cooling of the mobile terminal.
