How to use a Rubber in Mobile Phones Case Study

How to use a Rubber in Mobile Phones - Case Study Example These devices represent one of the most advanced (sophisticated) technologies ever developed by human beings (Karim 2010). Through them people can communicate with each other, surf on the internet, listen to music, watch videos, and play games among other functionalities. The various functionalities of mobile phones are normally enhanced by design and use of a variety of components in their manufacture. In this regard, mobile phones normally consist of several components, and these components are made from a wide variety of materials (Chan 2007). The materials from which mobile phones components are made include plastics, rubber, magnets, paper and metals among others. This paper, therefore, aims at investigating how rubber is currently used in the design and manufacture of mobile phones. The paper also aims at investigating the alternative areas in mobile phone design and construction that rubber can be used. Main parts of mobile phone and their use The main components of mobile pho nes are: battery, SIM card, circuit board, keyboard, speaker and microphone, antenna, software, and Liquid Crystal Display screen (commonly abbreviated as LCD screen) among others (Mueller 2013). Circuit board Circuit board is amongst the most important components of a mobile phone. ... The chips on the circuit board can perform numerous calculations (always millions of calculations) in a single second. The circuit board chips’ calculations are normally performed to decompress or compress voice stream (Harris 2006). Other than chips, another component that is available in the mobile phone circuit board is digital signal processor (commonly abbreviated as DSP) (Mueller 2013). This component is designed to perform operations related to manipulation of digital signals at greater speeds in a single second. Another component that is available in mobile phone circuit board is micro-processor. The microprocessor is responsible for three main functions; these functions are stated below: i. Coordination of all the functions of the mobile phone circuit board. ii. Processes commands as well as control signals related to connecting mobile phone to base station (also known as the cell phone tower). iii. Handles as well as coordinates the functions of display and keyboard. (Mueller 2013) Other components that are associated with mobile phone circuit board are ROM (the read only memory) and chips associated with flash memory. These components are responsible for the running and storage of the mobile phone’s operating system and software applications (Mueller 2013). Mobile phone’s speaker and Microphone Other than the circuit board, speakers and microphones are other important components of mobile phones. It is through the speakers as well as the microphones that communications between individuals are made possible (Harris 2006). Mobile phone microphone is responsible for converting the sound signals to electrical signals. The
