Abstract
Network Display speakers are used as public address (PA) systems as security
devices for effective communication of messages. Lately, one of the industry
leading companies within IP network product systems launched their own take on this. This thesis aimed at developing a new display speaker in collaboration with them, focusing on sustainability, user feedback and new features.

The project followed a Double Diamond design process. It started its research by
conducting interviews with relevant stakeholders regarding the current product. The
data gathered was analyzed and compiled into a technical specification, to act as a
basis for the iterative development phase. Development of the new solution was
divided into smaller segments... (More)

The project followed a Double Diamond design process. It started its research by
conducting interviews with relevant stakeholders regarding the current product. The
data gathered was analyzed and compiled into a technical specification, to act as a
basis for the iterative development phase. Development of the new solution was
divided into smaller segments that focused on one problem area at a time. Those
areas were: Mesh attachment, Display attachment, Sealing, Form & Layout and
speaker drivers. Lastly, solutions generated were evaluated and a final concept was
chosen and made into a prototype.

The final concept resulted in a portrait-oriented box with two speaker drivers and
larger display. The products strobe was located at the top corners, together with a
light indicator. At the bottom, a sunken motion detector was set to aid a potential
impact protection (IK) rating test. Within the product, printed circuit boards (PCBs) were reduced to three. The inside consisted of two separate chambers, one for audio and one for electrical components, with a seal between them made of compressed silicone. Each chamber was sealed by their respective front-plate, which exploited a radial seal. (Less)

Nätverkshögtalare med tillhörande skärm används i publika adresserings system
som en säkerhetsprodukt för tydlig kommunikation av meddelanden. För ett tag
sedan släppte ett av de industriledande företagen inom IP nätverks produkter sin egna tolkning av det. Detta examensarbete syftar på att utveckla en ny skärm- och nätverkshögtalare i samarbete med dem, som fokuserar på hållbarhet, användares återkoppling och nya funktioner.

Projektet följde Double Diamond design processen. Det startade sin undersökning
med att intervjua relevanta intressanter kring produkten. Datan som insamlades blev

Nätverkshögtalare med tillhörande skärm används i publika adresserings system
som en säkerhetsprodukt för tydlig kommunikation av meddelanden. För ett tag
sedan släppte ett av de industriledande företagen inom IP nätverks produkter sin egna tolkning av det. Detta examensarbete syftar på att utveckla en ny skärm- och nätverkshögtalare i samarbete med dem, som fokuserar på hållbarhet, användares återkoppling och nya funktioner.

Projektet följde Double Diamond design processen. Det startade sin undersökning
med att intervjua relevanta intressanter kring produkten. Datan som insamlades blev
analyserad och sammanställd i en teknisk specifikation, för att verka som grund för
den iterativa utvecklingsfasen. Utvecklingen av den nya lösningen blev uppdelad i
mindre delar som fokuserade på ett problem i taget. De problemen var: Meshfästen,
Skärmfästen, Tätningar, Form och Layout och Högtalarelement. Slutligen blev genererade lösningar utvärderade och ett slutgiltligt koncept blev valt och gjord till prototyp.

Det slutgiltliga konceptet resulterade i en porträttsorienterad låda med två
högtalarelement och större skärm. Produktens stroboskop blev placerad i de övre
hörnen tillsammans med en ljus-indikator. I nedre delen sattes en nedsjunken
rörelse-sensor för att hjälpa potentiella IK tester. Inuti produkten reducerades antal PCB till tre stycken. Insidan bestod av två separata kammare, en för ljud och en för elektriska komponenter, med en tätning mellan de gjort av komprimerad silikon. Varje kammare var förseglad med deras respektive framstycke, som utnyttjade en radial tätning. (Less)
