In Fig. 1 a flush-mounted radio device base is shown in exploded perspective view. The flush-mounted radio device base 1 is composed of the following structural components:

• a control panel, composed of a control panel lower part 7 and a control panel upper part 3,
• a receiver / amplifier board 13,
• a network board 18,
• a housing, composed of a housing lower part 23 and a housing upper part 30,
• a support ring 37.

In the operating element lower part 7, a display panel 9 (display) as well as near each corner of this display panel 9 per a sensing arm 11 are arranged. For electrical connection to the receiver / amplifier board 13 is a control connector 10, which in the Figures 2 and 4 is shown and which is inserted in the assembled state in a corresponding connector 14 of this circuit board 13. In the assembled state, latching lugs 8 of the operating element lower part 7 engage in corresponding latching openings 4 of the operating element upper part 3.

The receiver / amplifier board 13 has, in addition to a radio receiver part and an amplifier and the above-mentioned connector 14, a speaker terminal block 15 which not only has the screw terminals for two speakers, but also the external antenna connection terminal for an external audio source and a connection for an "audio sink" or an "audio input", more precisely "line-out" and "line-in". At the rear of the receiver / amplifier board 13 is a switch 16 for switching between an internal antenna and an external antenna, which is shown in FIG Fig. 5 is shown. The internal antenna is z. B. realized in the form of a grid connection, protected by two Y-capacitors.

In addition to a power supply unit, the network printed circuit board 18 has a power supply connection block 19 for connection to an AC voltage network, wherein this connection block 19 additionally enables an extension connection 19. The electrical connection between mains circuit board 18 and receiver / amplifier circuit board 13 is carried out using connecting lines 20, 21st

For mounting the flush-mounted radio device base, the power circuit board 18 is first inserted into the housing base 23, wherein the exact mounting position is determined by support platforms 24. A window 26 inserted in the housing lower part 23 allows access to the power supply connection block 19 and thus the subsequent connection of lines of an AC voltage network to the flush-mounted radio device base. After attaching the connecting lines 20, 21, the receiver / amplifier circuit board 13 is inserted into the housing base 23, wherein the exact mounting position is determined by support platforms 27.

Finally, the thus equipped housing lower part 23 is locked to the housing upper part 30. For this purpose, latching lugs 31 of the housing upper part 30 engage in corresponding latching openings 25 of the housing lower part 23. These locking lugs 31 are located on two opposite tabs 32 of the housing upper part 30, which engage in the assembled state in the housing lower part 23. The lower edges of these tabs 32 press in the mounted state against the power circuit board 18, whereby the latter is fixed within the housing. The fixation of the receiver / amplifier circuit board 13 within the housing in the assembled state is similar to this, by walls 34 of the housing shell 30 dive into the housing base 23 and press with their lower edges against this circuit board 13.

When latched together housing parts 23, 30 recesses 28 and 35 in the lower housing part 23 and in the housing upper part 30, the accessibility to the screw terminals of the speaker terminal block 15 safe.

In Fig. 1 In addition, a latching nose 33 can be seen, which serves together with further, hidden in the perspective view shown detent lugs to connect the support ring 37 with the housing upper part 30.

It is the control element upper part 3, the display panel 9, the four arranged in the vicinity of the corners of the display panel 9 sensing arms 11 and the support ring 37 to recognize with its keyholes 38. The arrangement of the installation device completing cover 40 is sketched in broken lines.

The flush-mounted radio base unit becomes after connection of speaker cables, the cable of an external antenna (optional), the lines of an external audio source (optional), the lines of an AC mains (phase conductors, neutral) and the line of an extension (optional) in one commercially available standard sub-socket (for electrical installation equipment of a building installation system) introduced. The assembly is carried out by suitable screws through two of the four key holes 38 of the support ring 37 and screwed into corresponding pockets on the wall of the flush box. To complete the C-disk (center disc) and cover frame from different programs with different design and different colors can be selected in the desired manner. Such flush-mounted programs are available in different shapes, different colors and using different materials (eg plastic, stainless steel). In this way, the radio is integrated harmoniously into a flush-mounted program and does not constitute a "foreign body" with regard to sockets, switches, dimmers, push-button sensors and motion detectors. Furthermore, the radio can be used in multiple combinations (eg 2gang combination , 3-gang combination, 4-gang combination) together with switches, dimmers, etc. are used. Furthermore, there are a variety of different combination options, eg. B. with regard to possible color combinations.

In Fig. 7 is a view of the front of a complete flush-mounted radio is shown, wherein a C-disk (central disk) 41 with arranged in its four corners of the control buttons 42 on the one hand contains the central display panel 9 and on the other hand is enclosed by a cover frame 40. The control buttons 42 act on the sensing arms 11 via plunger on its underside.
