Embodiment Construction

[0023] This description refers to a communication terminal in which the speaker structure according to the present invention is to be implemented as a device. Communication terminals include all mobile devices designed for radio communication via a radio station, wherein the radio station can also be a mobile terminal or, for example, a stationary base station. Thus, the term "communication terminal" includes mobile phones, pagers, transmitters, electronic organizers, smartphones, PDAs (Personal Digital Assistants), vehicle radios or similar devices, and Laptop in wireless communication. In addition, since the design and the present invention are suitable for, but not limited to, mobile applications, the term "communication terminal" should also be understood to include any radio communication device designed to handle communications with each other or with other radio stations. Stationary equipment for radio communication between, for example, such as desktop computers, prin...

Abstract

A communication terminal includes a housing carrying therein a radio antenna element, a speaker, and a chamber that acts as an electromagnetic resonance cavity for the antenna and as an acoustic resonance cavity for the speaker. The speaker is mounted inside the chamber and is coupled to the outside of the housing through a sound channel. The terminal includes a user interface on a front side of the housing and the speaker is placed behind the user interface as viewed from the front side, with the sound channel extending from a channel inlet at the speaker to a channel front outlet at the front side.

Description

technical field [0001] The invention generally relates to a communication terminal comprising an antenna for wireless communication purposes and a loudspeaker for transmitting audio information to a user of the communication terminal. More specifically, the present invention relates to a communication terminal in which the above-mentioned speaker is arranged inside a resonant cavity of the antenna. Background technique [0002] The mobile phone industry has grown tremendously in terms of quality of service, transmission capabilities, and technologies to produce advanced communication terminals. In just a few decades, communication systems have undergone a transition from analog to digital, and at the same time, the size of mobile terminals has changed from the size of a briefcase to the pocket-sized phones of today. Also, mobile phones are getting smaller and smaller, and size is generally considered to be an important factor for end users. The development of electronics h...
