Gadget: Acoustic Speaker
About our Gadget: The phone will sit directly in the centre of the speaker with approximately 3cm on either side. The phone will only sit slightly in its holder (~10mm deep), allowing easy access to the whole phone and there will be a cut out around the home button. The speaker itself works off of 2 holes that connect to the speakers of the phone through the hollow base structure of the speaker. As an end result, the acoustics of the speaker will amplify the sound from the phone.
Initial Sketch Photo:
The phone sits in a base that has two cup like structures on either end. The speaker will reply on acoustics to amplify the sound.
Initial Clay Model:
Our design is one elongated structure with a hole through the centre base. A back rest for the phone is there for support.
Draft Product Photo:
Our first printing attempt was quite successful however the support given to the phone needs to be greater.
Final TinkerCAD Design Photo:
Our final design added support for the phone and the speakers were made more cupped as to increase the amplification.
Design Reflection: The process of making our speaker was very simple and streamlined once getting the blueprint into TinkerCAD. When sketching and making the clay model we struggled to get everything dimensionally correct, but TinkerCAD allowed us to manipulate each dimension individually. This allowed us create our final product after not much work.
What do you think the hardest part of these past 4 weeks (besides class time!)?
ReplyDeleteThe hardest part during these past four weeks has been working out the two cup shapes inside TinkerCad. As the software really only works in predetermined shapes, getting the correct rounded shape for both cups that increases projected volume was very difficult. In the end we had to compromise by making the cups rounded, but the inside of them are not the best shape for optimal acoustics. While it does work, the ending sound is projected, it still has room for improvement that the software is unable to perform.
DeleteHow did you know how big you wanted the speakers to be?
ReplyDeleteTo create a speaker that was not too large, but not too small to decrease volume output, we scaled it outwards from the hole in which you place your phone. We created that stand to the dimensions of a standard IPhone 6, then took that dimension and multiplied it by two and a half times to get the length from end to end.
DeleteIf you had one thing you could go back and change in your design what would it be?
ReplyDeleteBecause of the limitations of TinkerCad, the inside of the cups don't have the perfect shape to increase the acoustics to their maximum potential. If we could go back, we would try looking for a way to create these changes. But sadly because of the schedule we had to compromise these designs and just settle with round cups.
DeleteHow efficient does your speaker work?
ReplyDeleteThe speaker does amplify sound to a noticeable degree. But because of a few design choices and limitations there is still room for improvement. But at the end of the day, our created speaker was a success that increases the volume of sound sent through it.
DeleteDo you think adding another speaker hole right in the center, closer to where the music is coming from the phone, help the sound amplify or hurts it?
ReplyDeletewhy a speaker?
ReplyDeleteI saw the look of your phone inside the speaker. but what if another person phone does not have the speaker at the bottom of it?
ReplyDeleteIf the phone has its speakers in the bottom part, anywhere below where the home button is placed on an IPhone, then our speaker is designed to work. The phone sits low enough, along with hollow walls on all sides, the speakers are not constricted by anything. This allows sound to flow freely and be amplified by our speaker.
DeleteCan this work with all types of smart phones?
ReplyDeleteDoes the device alter the highs/lows of the sound output from the phone? Does it sound better that way?
ReplyDeletedo you think your speaker will produce a good amount of sound compared to an actual speaker?
ReplyDeleteAre there still problems you guys are still trying to overcome with the the design.
ReplyDeleteYes. We are not able to fit a phone with a case inside the speaker as the hole is not big enough.
Deletedo you know how much loader the speaker will make the music
ReplyDeleteWe can not calculate how much louder the speaker will make the music as we have limited technology. However, we can be sure that the speaker does amplify the sound from the phone.
