About The Voice of Ceramic Resonanzlautsprecher

„The Voice of Ceramic“ ist eine Serie von Resonanzlautsprechern aus Keramik für Mobiltelefone. Die Lautsprecher verstärken den Klang ohne jede Stromversorgung, es wird also keine Elektrizität benötigt. Das Mobiltelefon wird senkrecht in eine Nut in der Mitte des Korpus gestellt. Der Schall aus der Klangöffnung des Telefons gelangt in die Resonanzkammer und wird dort verstärkt, wobei die Bässe hervorgehoben werden. Die Musik tritt aus zwei Öffnungen links und rechts aus und erzeugt so einen Stereoeffekt. Die Lautstärke desselben Musikstücks kann um 12 dB gesteigert werden. Keramik blickt in China auf eine lange Tradition als Werkstoff für Musikinstrumente zurück.

Unique Properties: The Voice of Ceramic is a series of resonance speakers made of china for mobile phones. It naturally amplifies volume without a power supply, and obviously reduces carbon emissions. The sound from sound outlet of mobile phone is amplified in volume when entering the resonance chamber. For the same piece of music, the loudness can be increased by 12 dB through this speaker due to the effects of sound convergence and resonance.
Dimensions & Packaging: Width 230mm x Depth 65mm x Height 65mm

Production Technology: The Voice of Ceramic is a series of resonance speakers made of china for mobile phones. The sound from sound outlet of mobile phone is amplified in volume when entering the resonance chamber. For the same piece of music, the loudness can be increased by 12 dB through this speaker due to the effects of sound convergence and resonance.
Design Challenge: The biggest difficulty in the design and development of this product is the realization of materials and technology. The molding accuracy of ceramics is difficult to control, and the deformation after firing is uncertain.
Repeated calculations and testing have been made on its shape, size, center of gravity, orientation of pipe orifice, and the placement and angle of mobile phones.
Research: Over the years, Apple has endeavored to reduce carbon emissions and the impact of its products on environment to a minimum level. This resonance speaker box amplifies volume naturally without power supply, which fits well the notion of Apple. Repeated calculations and testing have been made on its shape, size, center of gravity, orientation of pipe orifice, and the placement and angle of mobile phones. Glazing the china with different ceramic glazes, the speaker boxes will have varied colors.
Inspiration: China has always been a suitable material for making musical instruments. There is a long history of the use of china(ceramic) as a material for making musical instruments. Porcelain Drum which is the famous Chinese ancient musical instrument, is made of china.
Project Duration: The series was designed and created in 2013 in Hangzhou, China, and then gradually improved and expanded until 2019.
Operation Flow: A mobile phone can be placed vertically into the groove in the middle of the resonance speaker box, and sound from the sound outlet of the mobile phone enters the resonance chamber to form resonance, thereby amplifying volume (in particular, the bass is strengthened). Music will be spread from both right and left sound outlets, which enables the sound from an outlet of the mobile phone to create a stereo effect.
