DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) FIG. 1 is an illustration of an opening defined in a surface as used for an installation of an embodiment of a flat panel speaker in accordance with the present disclosure. In particular, a surface 10 has defined therein an opening 20. The surface 10 is the front surface of a plasterboard layer of a substantially vertical wall. The opening 20 is defined in the surface 10 by a series of cuts, resulting in a substantially rectangular opening 20 within the surface 10. The opening 20 has a horizontal extent of 40 centimeters and a vertical extent of 60 centimeters.

(10) Although embodiments have described the surface 10 as a plasterboard layer of a substantially vertical wall, in one embodiment, the surface 10 is the whole thickness of the wall. The surface 10 can alternatively be a substantially horizontal surface such as a table or floor or ceiling. In one embodiment, the surface 10 is a layer of a ceiling, for example a ceiling tile. Although embodiments have described the opening 20 as being defined by a series of cuts, the opening 20 can alternatively be defined by the edges of the surface 10. Similarly, although embodiments have described the opening 20 as rectangular, it will be appreciated that alternative shapes may be used as required to fit with the shape of the flat panel speaker.

(11) FIG. 2 is an illustration of an installation of an embodiment of a flat panel speaker in accordance with the present disclosure. A flat panel speaker 50 comprises a mounting unit in the form of a backing box 52. The backing box 52 is connected to a speaker unit 54 which is inserted in and retained by the backing box 52. The speaker unit 54 extends outwardly from a front of the backing box 52. The backing box 52 protects a back surface of the speaker unit 54. The speaker unit 54 is seated in the backing box 52. The backing box 52 has a footprint which is larger than the speaker unit 54 in one direction. The backing box 52 is typically formed from metal.

(12) The speaker unit 54 comprises a flat panel and operates as a distributed mode loudspeaker. The speaker unit 54 is configured to generate sound when vibration modes are induced in the flat panel by an exciter (not shown). Two holding portions are provided on the flat panel speaker 50 in the form of a lower loop strap 56 and an upper loop strap 58. Each of the lower loop strap 56 and the upper loop strap 58 is attached to the backing box 52. The lower loop strap 56 extends past a bottom edge of the speaker unit 54. The upper loop strap 58 extends past a top edge of the speaker unit 54. The lower loop strap 56 and the upper loop strap 58 are formed from fabric to ensure they are flexible and are arranged to be able to withstand forces due to the weight of the flat panel speaker and the pulling of the flat panel speaker against the rear of the surface of the wall during mounting. In an alternative embodiment as shown in FIG. 7, a single holding portion 156 may be provided as a fabric strap or webbing attached to the backing box and extending from the top to the bottom of the flat panel speaker.

(13) The opening 20 is dimensioned to substantially correspond to the dimensions of the panel of the speaker unit 54. The backing box 52 is dimensioned to be larger than the opening 54 in an axis of the backing box extending in the plane of the mounting surface to enable mounting of the backing box to the rear of the surface, for example by using screw fixings, but is otherwise dimensioned to enable the speaker unit to be passed through the hole into the surface by canting (e.g. by the backing box 52 and speaker unit 50 as a whole being marginally smaller than the opening in another axial direction of the plane of the opening 20).

(14) The or each holding portion is configured to extend through the hole to allow the pre-assembled speaker 50 to be passed through the opening 20 and held in place flush with the surface 10 of the wall, despite there being only a small gap between the wall 10 in the opening 20 thereof and the edge of the panel of the speaker unit 54.

(15) As can be seen in FIG. 2, a first stage of installing the flat panel speaker 50 in an opening 20 defined in a surface 10 is to pass a region of the backing box 52 in the vicinity of the lower loop strap 56 through a lower portion of the opening 20. The height of the backing box 52 is greater than the height of the opening 20. In order for the backing box 52 to be entirely passed through the opening 20, it will be appreciated that the backing box 52 must be passed through the opening 20 at an angle and canted into position.

(16) FIG. 3 is a further illustration of the installation of the flat panel speaker shown in FIG. 2. As can be seen in FIG. 3, a second stage of installing the flat panel speaker 50 in an opening 20 defined in a surface 10 is to move the backing box 52 vertically downwards, such that a region of the backing box 52 in the vicinity of the upper loop strap 58 can pass through an upper portion of the opening 20. An installing user can hold the upper loop strap 58 and the lower loop strap 56 during this process to ensure that the flat panel speaker 50 can be correctly maneuvered in the opening 20. The upper loop strap 58 and the lower loop strap 56 can also be held to keep the flat panel speaker 50 from falling down behind the surface 10.

(17) FIG. 4 is another illustration of the installation of the flat panel speaker shown in FIGS. 2 and 3. Once the flat panel speaker 50 has been fully passed through the opening 20 as shown in FIG. 3, the installing user can use one or both of the upper loop strap 58 and the lower loop strap 56 to hold the flat panel speaker 50 in place in the opening 20 as shown in FIG. 4. In particular, a contacting surface of the backing box 52 (not visible in FIG. 4) is held against a back surface of the plasterboard layer (opposite the surface 10). The installing user uses the upper loop strap 58 and the lower loop strap 56 to hold the flat panel speaker in place in the opening 20 without having to touch the speaker unit 54, which may be delicate. The speaker unit 54 protrudes from the backing box 52 such that, in position, a front surface of the speaker unit 54 is substantially flush with the surface 10. Only a small gap is provided between the speaker unit 54 and the surface 10, such that the speaker unit can be inserted into the opening 20, and the upper loop strap 58 and the lower loop strap 56 can pass through the opening 20 between the surface 10 and the speaker unit 54.

(18) FIG. 5 is yet another illustration of the installation of the flat panel speaker shown in FIGS. 2 to 4. Whilst the installing user continues to hold the flat panel speaker 50 in place in the opening 20, the same installing user or a further installing user can secure the flat panel speaker 50 in place in the surface 10. A series of mounting holes 62 are provided in the surface 10 above and below the opening 20, formed, for example, by drilling. The mounting holes 62 are positioned within the footprint of the backing box 52. In this way, a corresponding series of mounting screws 60 can pass through the mounting holes 62 of the surface 10 and engage with corresponding holes (not shown) in the backing box 52 to fixedly secure the speaker unit 50 in the opening 20. A head portion of each of the mounting screws 60 is configured to be countersunk in the surface so as to not to pass entirely through the mounting holes 62 in order to allow the head portion of the mounting screws 60 to be retained within the plasterboard layer.

(19) Although the presently described embodiment has used mounting holes 62 and mounting screws 60 to secure the flat panel speaker 50 to the surface 10, it will be appreciated that alternative securing techniques will be apparent to the person skilled in the art and can be used. For example, one or both of the upper surface of the backing box 52 and the back surface of the plasterboard layer could have one or more adhesive regions to hold the flat panel speaker 50 in place in the opening 20.

(20) FIG. 6 is a yet further illustration of the installation of the flat panel speaker shown in FIGS. 2 to 5. After the flat panel speaker 50 has been fixedly secured in the opening 20, the installing user is no longer required to use the upper loop strap 58 or the lower loop strap 56 to hold the flat panel speaker 50 in place. In this particular embodiment, the upper loop strap 58 and the lower loop strap 56 are removed from the installed flat panel speaker 50 by cutting or tearing. For example, a knife (not shown) is used to cut the strap at or beneath the level of the opening 20, such that a stub of the upper loop strap 58 or the lower loop strap 56 does not protrude out of the opening 20. It will be appreciated that other ways of removing the upper loop strap 58 or the lower loop strap 56 can be used. For example, in some embodiments, one or both of the upper loop strap 58 and the lower loop strap 56 may be retractably attached to the backing box 52, such that the straps are configured to be pushed back through the opening so that the straps do not protrude out of the opening 20.

(21) Once the flat panel speaker 50 is installed in the opening 20, any securing means such as mounting screws 60 and mounting holes 62 can be painted or plastered over. The gap between the surface 10 and the edge of the panel of the speaker unit 54 can be sealed, for example with jointing tape, and the whole surface can be finished with a skim plaster. The front surface of the speaker unit 54 can also be finished in substantially the same colour and texture as the surface 10. This ensures that the flat panel speaker 50 is substantially visually indistinguishable as a separate part of the surface 10, such that it is effectively ‘invisible’.
