TECHNICAL FIELD
The present disclosure relates to a siren assembly of a vehicle alarm system. More particularly, the present invention relates to a sealing arrangement for facilitating fluid-tight packaging of the siren assembly.
BACKGROUND
A vehicle alarm system (VAS) comprises of a siren assembly generally installed on a vehicle roof. The siren assembly of the vehicle alarm system produces sound signals during occurring of certain uncommon events. The uncommon events include, such as but not limited to, a major shock experienced by the vehicle, an unauthorized access to the vehicle, an unauthorized attempt to open vehicle door or vehicle boot area, and an unauthorized attempt to start the vehicle.
Figure 1 illustrates an exploded view of the currently known siren assembly [100]. The currently known siren assembly [100] includes a diaphragm assembly [102] and an electronic circuit [104], which work in conjunction to produce sound signals of desired frequency. The currently known siren assembly [100] further comprises of a first container member [106], a second cover member [108], and a propeller member [110], to house and mount the diaphragm assembly [102] and the electronic circuit [104]. A plurality of sets of screws may also be used to attach various components of the currently known siren assembly [100] with each other, for enabling the currently known siren assembly [100].
In assembly of the currently known siren assembly [100], the diaphragm assembly [102] is initially assembled together. Thereafter, the diaphragm assembly [102] is positioned below a base surface [112] of the first container member [106], such that a portion of the diaphragm assembly [102] extends within the base container member [106]. A first set of screw [114] then assembles the diaphragm assembly [102] and the electronic circuit [104] with the first container member [106]. Thereafter, the electronic circuit [104] is

positioned within the second cover member [108]. After such positioning, the second cover member [108] is attached to the first container member [106] with use of a second set of screws [116], to house the diaphragm assembly [102] and the electronic circuit [104] therein. Thereafter, the propeller member [110] is attached to and mounted on the first container member [106] with use of a third set of screws [118], to house the diaphragm assembly [102] within the base container member [106]. With such arrangement, the siren assembly is entirely assembled.
With such currently known siren assembly [100], in certain situations, water may enter within the siren assembly [100]. For example, water may enter into the siren assembly [100] through attachment portions surrounding the first set of screws [114], the second set of screws [116], and the third set of screws [118]. Water is also likely to enter through an interface between components of the siren assembly [100]. For example, water may enter the siren assembly through an interface between the first container member [106] and the second cover member [108], and through an interface between the first container member [106] and the propeller member [110]. Moreover, water is also likely to enter through a wire exit port provided in the second cover member [108]. Such intrusion of water within the siren assembly [100] may cause short circuiting of either of the diaphragm assembly [102] and the electronic circuit [104]. This may cause operational failure of the currently known siren assemblies [100].
Thus, in view of the above and other drawbacks and limitations of the currently known siren assembly [100], it is essential to develop a siren assembly [100] with a sealing arrangement for facilitating fluid-tight packaging of the siren assembly [100]. The above-mentioned information in the background section is only intended to enhance the understanding of the reader with respect to the field to which the present invention pertains. Therefore, unless explicitly stated

otherwise, any of the features or aspects discussed above should not be construed as prior art merely because of its inclusion in this section.

Figure 3 shows an assembled perspective view of the siren assembly [200] of the vehicle alarm system, in accordance with the concepts of the present disclosure. Figure 4 shows a transparent view of the siren assembly [200], in accordance with the concepts of the present disclosure. Figure 2, Figure 3, and Figure 4 should be referred to in conjunction to clearly understand the scope of the present

disclosure. The siren assembly [200] includes a diaphragm assembly [204], an electronic circuit [202], a housing assembly [206], and a sealing arrangement [208].
The electronic circuit [202] is an electronic control circuit with programmed microcontroller powered by a vehicle battery. The electronic circuit produces electrical signals of defined frequencies in defined sequence, when powered by the vehicle battery. Further, the electrical signals of the defined frequencies in the defined sequence is outputted to the diaphragm assembly [204].
The diaphragm assembly [204] comprises of a transducer (not shown in the figure) that receives the electrical signals from the electronic circuit [202]. Upon receiving the electrical signals from the electronic circuit [202], the diaphragm assembly [204] starts vibrating causing the diaphragm assembly [204] to produce sound signals. Moreover, the frequency and amplitude of the sound signals produced by the diaphragm assembly [204] is dependent on and corresponds to the frequency and sequence of the electrical signals produced by the electronic circuit [202].
The housing assembly [206] and the sealing arrangement [208], in conjunction with each other, supports and houses the electronic circuit [202] and the diaphragm assembly [204] in fluid-tight manner. In particular, the housing assembly [206] houses and supports, the electronic circuit [202] and the diaphragm assembly [204], while the sealing arrangement [208] assist in facilitating fluid-tight packaging of the electronic circuit [202] and the diaphragm assembly [204] within the housing assembly [206].
The housing assembly [206] includes an inner casing container [210], an outer casing container [212], a propeller [214], a first set of screws [216], a second set of screws [218], a third set of screws [220], and a fourth set of screws. The inner casing container [210], the outer casing container [212], and the propeller [214],

in conjunction with each other, are provided to mount and house the electronic circuit [202] and the diaphragm assembly [204], with use of the first set of screws [216], the second set of screws [218], the third set of screws [220], and the fourth set of screws. The inner casing container [210] is an open-top cuboidal container including a base surface [222], such that the base surface [222] has a cavity therein. The outer casing container [212] is an open-top container with a lower cylindrical section and an upper cuboidal section. The diaphragm assembly [204] allows the sound signals from the diaphragm assembly [204] to come out in the surrounding environment through the propeller [214], with relatively increased amplitude of the sound signals.
The sealing arrangement [208] includes a first set of seal rings (not shown), a second set of seal rings (not shown), a third set of seal rings (not shown), a fourth set of seal rings (not shown), a fifth sealing member [224], a sixth sealing member [226], and a seventh sealing member [228]. Each of the components of the sealing arrangement [208] are provided with one or more components of the housing assembly [206], to enable fluid-tight packaging the electronic circuit [202] and the diaphragm assembly [204] within the housing assembly [206].
In assembly of the siren assembly [200], initially, the diaphragm assembly [204] is assembled together. Thereafter, the diaphragm assembly [204] is positioned at a lower side of the base surface [222] of the inner casing container [210], such that a portion of the diaphragm assembly [204] extends within the inner casing container [210]. While doing so, the fifth sealing member [224] is positioned at an interface between the diaphragm assembly [204] and the base surface [222] of the inner casing container [210]. In particular, the fifth sealing member [224] is sandwiched between the diaphragm assembly [204] and the base surface [222] of the inner casing container [210] around the cavity. This prevents intrusion of water within the inner casing container [210], through the cavity of the inner casing container [210]. Upon such positioning of the diaphragm assembly [204]

and the fifth sealing member [224] relative to the inner casing container [210], the diaphragm assembly [204] is fixedly attached to the base surface [222] of the inner casing container [210] with use of the first set of screws [216]. In particular, the first set of screws [216] attach the diaphragm assembly [204] to the base surface [222] of the inner casing container [210]. Notably, the first set of screws [216] are provided with the first set of seal rings, to provide fluid-tight attachment between the attachment portions of each of the base surface [222] of the inner casing container [210] and the diaphragm assembly [204]. This prevents intrusion of fluid within the inner casing container [210], through the attachment portions (attachment holes) of the inner casing container [210].
After positioning the diaphragm assembly [204] with the inner casing container [210], the electronic circuit is positioned within the cylindrical section of the outer casing container [212]. Thereafter, an assembly of the diaphragm assembly [204] and the inner casing container [210] is positioned within the cuboidal section of the outer casing container [212]. The inner casing container [210] is then fixedly attached to the outer casing container [212], to retain the assembly of the diaphragm assembly [204] and the inner casing container [210] within the outer casing container [212]. The inner casing container [210] is then fixedly attached to the outer casing container [212], with use of the second set of screws [218]. Furthermore, the second set of screws [218] are provided with the second set of seal rings, to provide fluid-tight attachment between the attachment portions of the inner casing container [210] and the outer casing container [212]. This prevents intrusion of fluid within the inner casing container [210] and the outer casing container [212], through the attachment portions (attachment holes) of the inner casing container [210] and the attachment portions (attachment holes) of the outer casing container [212]. Upon such assembly, a sixth sealing member [226] is installed on top of the inner casing container [210] and top of the outer casing container [212], to provide fluid-tight attachment between the inner casing container [210] and the outer casing

container [212]. Furthermore, each of the inner casing container [210] and the outer casing container [212] has a wire routing port, to allow a wire harness of the diaphragm assembly [204] to exit from the inner casing container [210] and the outer casing container [212]. The wire outing port is provided with the seventh sealing member [228], to prevent intrusion of fluid therein through the wire outing port.
Thereafter, the propeller [214] is installed within the inner casing container [210], such that the propeller [214] covers the portion of the diaphragm assembly [204] extending within the inner casing container [210]. To do so, the propeller [214] is fixedly attached to the base surface [222] of the inner casing container [210] with use of the third set of screws [220]. The third set of screws [220] are provided with the third set of seal rings, to provide fluid-tight attachment between the attachment portions of the inner casing container [210] and the propeller [214]. This prevents intrusion of fluid within the inner casing container [210], through the attachment portions (attachment holes) of the inner casing container [210] and the attachment portions (attachment holes) of the propeller [214]. With such attachment, the assembly of the siren assembly [200] is completed. Finally, the siren assembly [200] is installed on a vehicle body, by attaching the outer casing container [212] to the vehicle body with use of a fourth set of screws. The fourth set of screws are provided with the fourth set of seal rings, to provide fluid-tight attachment between the attachment portions of the outer casing container [212] and the vehicle body. This prevents intrusion of fluid within the outer casing container [212], through the attachment portions (attachment holes) of the outer casing container [212]. With such arrangement of the housing assembly [206] and the sealing assembly [208], the siren assembly [200] is packed in a fluid-tight manner.
Referring to Fig, 4, there are shown some exemplary portions of the siren assembly [200], named portion A, portion B, portion C, portion D, and portion E,

through which intrusion of fluid is prevented to be flown within the siren assembly.
With respect to portion A, the third set of seal rings are provided on the third set of screws [220], to prevent intrusion of fluid through the attachment portions (attachment holes) of the inner casing container [210] and the attachment portions (attachment holes) of the outer casing container [212]. With respect to portion B, the fifth sealing member [222] prevents intrusion of fluid into the inner casing container [210], through the cavity in the base surface [222] of the inner casing container [210]. With respect to portion C, the sixth sealing member [226] is provided on top of the inner casing container [210] and the outer casing container [212], to prevent fluid intrusion in a gap between the inner casing container [210] and the outer casing container [212]. With respect to portion D, the first set of seal rings prevents are provided on the first set of screws [216], to prevent intrusion of fluid through the attachment portions (attachment holes) of the inner casing container [210]. With respect to portion E, the seventh sealing member [228] is provided to prevent intrusion of fluid through the wire routing port of the inner casing container [210] and the outer casing container [212]. Thereby, the fluid intrusion inside the siren assembly [200] is prevented, resulting in improved operational life of the siren assembly [200].
