Embodiment Construction

[0019] Figure 1a shows a conventional type of portable audio device 1 having eg a radio, tape recorder and CD player. These elements are accommodated in a casing 2 made of injection molded plastic. The device 1 is equipped with two sets of speakers 3a and 3b on the left and right sides of the cabinet 2 for stereoscopic reproduction of sound. By comparing Figures 1a and 1b, it can be seen that the device shown in Figure 1b has a larger loudspeaker enclosure than the device shown in Figure 1a. The structure shown in Figure 1b gives the user the impression that the device is more powerful than the device shown in Figure 1a, even though the two devices are technically identical except for the speakers and / or speaker enclosures. For marketing purposes, this difference is often required to enable manufacturers to cater to different aspects of the market. However, this difference results in increased manufacturing costs for different types of enclosures.

[0020] In Figures 2a and...

Abstract

The invention relates to a cabinet for household electronic devices with loudspeaker, which is comprised by a main cabinet for the accommodation of electronic devices and mechanical element, and a separate loudspeaker cabinet which can be fixed to the external side of the main cabinet in undetachable wise. In this wise, different electronic devices can be designed based on the same main cabinet, therefore, the production cost can be greatly reduced.

Description

technical field [0001] The present invention relates to everyday electronic devices equipped with loudspeakers. Examples of such devices are audio devices such as CD players, tape recorders, radios, and televisions. In particular, the invention relates to devices in which the loudspeaker is formed as an integral part. Background technique [0002] In known electronic devices of this type, as shown in Figures 1a and 1b, the housing is formed as a single piece for housing the electronic and mechanical components. Electronic components also include power supplies and signal processing circuits. The mechanical element may be a tape recorder and / or a CD player. The cabinet serves as a structural element suitable for arranging all the elements required for the device. Furthermore, the case protects the user from electric shock and protects the components from damage due to external influences such as dust or moisture. Finally, the enclosure provides the design of the device, ...
