Design of modern speaker body with usage of new technology
Kůst, Martin ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This diploma thesis deals with the analysis and design optimization of a speaker cabinet (enclosure) produced by the additive technology of 3D sand printing. The introductory part is devoted to the theory, both in the field of noise, vibration and the method of their calculations, as well as the theory of speakers and their systems. Numerical and experimental modal analysis is performed, which were compared to determine the mechanical properties of the new material, including material damping. This is followed by experimental and numerical harmonic analysis, with output in the form of a numerical model describing the behaviour of the structure during its excitation. The data are compared with a modal analysis of the internal acoustic space and the critical shapes and their frequencies are determined. At the end of the work, construction modifications are proposed to increase the rigidity of enclosures, the influence of which is evaluated on the created numerical models.

System for Recording and Repeating of Events for Sound Systems
Klobása, Jiří ; Černocký, Jan (referee) ; Zemčík, Pavel (advisor)
This thesis deals with the design and implementation of system for recording and repeating of events for audio systems. The introductory part is devoted to the study of sound systems, their user interfaces and communication protocols that are used by audio systems. Hereafter the description of essential features of Mac OS X, as well as the characteristic of its user interface and principles of development on this platform, are given. The core of the thesis consists of the design of system for recording and repeating of events and the concept of events which specifies the reprezentation of events in the system and their subsequent processing. In~the end of the thesis is presented the implementation of the designed system for Mac OS X with respect to possible extensions of the system and its features.

Design of Portable Audio System
Myška, Miroslav ; Zvonek, Miroslav (referee) ; Sládek, Josef (advisor)
The topic of this bachelor’s thesis is Design of Portable Audio System. These systems were very famous in past, but the glory falls in the present. The main aim of this design is to create portable audio system with high performance and modern technology and fulfilling ergonomic, technical, and aesthetic demands.

Design of PC loudspeakers.
Machálek, Róbert ; Sládek, Josef (referee) ; Křenek, Ladislav (advisor)
The topic of my bachelor’s thesis is a system of loudspeakers for personal computer. The purpose is to design original conception of the product with the assumption to create unique solution. This thesis includes close report about solution of my design, 3D digital model and visualizations and a model of loudspeakers system scaled 1:1.
