Matrix headphone amplifier for studio monitoring
Štěrba, Václav ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor´s thesis describes the design of a matrix headphone amplifier for studio monitoring. The proposed amplifier is a purpose-built device to be used in studio sound recording for the mixing of multiple audio channels directed to the interpreters´or performers´ headsets. The device is basically composed of the following parts: An input section for the audio line, a mixing section which secures the setting of individual input levels for each output, an amplifier section allowing the setting of the output signal level for each output, and an output section enabling the connection of headphones. The equipment utilizes a connection to a multi-channel audio signal bus; this bus also provides for remote power supply to all the connected devices. The solution described in the thesis can be defined as alternative monitoring that facilitates quick and easy connection of a required number of monitoring points (in other cases, such monitoring is usually realized by means of individual small mixing consoles).

Design of magnetoplanar headphones with amplifier
Chyťa, Filip ; Búran, Martin (referee) ; Skácel, Josef (advisor)
This work deals with comparison of individual types of electroacoustic transducers, their properties and practical use. Furthermore, design and manufacture of a magnetoplanar transducer, its integration into headphones and the production of headphone amplifier. The first chapter summarizes all types of electroacoustic transducers, their properties, advantages, disadvantages, and their use in practice. The second chapter deals with the classes of amplifiers. The third chapter deals with the choice of design of a magnetoplanar transducer, headphones, and selected type of headphone amplifier. The last chapter describes the production process of individual parts of the headphones, transducer and amplifier, including the final measurement.

Laboratory Device for Measuring Headphones
Holub, Kamil ; Číž, Radim (referee) ; Schimmel, Jiří (advisor)
This bachelor's thesis deals with the design and assembly of headphones test fixture. The introduction describes the types of headphones, their classification in terms of design and their typical specifications followed by a description of instruments for measuring headphones, defined by standards ČSN EN 60318 and their classification in terms of design and use. The following part is devoted to a design of a test fixture, which is subsequently put together using 3D printing. As part of the thesis, the measurement of frequency response and input impedances of various headphones is performed on the fixture. These are then compared with measurements on professional measuring devices. In the last part is described a laboratory task, which includes the measurement of headphones using this test fixture.
