Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a dashboard speaker assembly. Background Technology

[0002] To meet the growing demand for mobile audio-visual entertainment from users and passengers, the lighting and audio or speaker systems in vehicles are usually separate. The lighting only serves the purpose of illumination and does not involve audio-visual entertainment, while the audio or speaker systems meet general entertainment needs.

[0003] The connection between the existing built-in light source (LED or LED strip) and the circuit board is prone to breakage, especially when the vehicle is bumpy, brakes suddenly, or vibrates, the built-in light source will not emit light due to poor contact. Utility Model Content

[0004] The purpose of this invention is to provide an instrument panel speaker assembly that solves the problem of unstable light emission from the light source.

[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figure 1 and Figure 2 and Figure 3 As shown, an instrument panel speaker assembly includes a horn mechanism 1 and a light-emitting mechanism 2. The horn mechanism 1 is mounted on the upper part of the vehicle instrument panel. The horn mechanism 1 includes a housing 11, a sound-transmitting cover 12, and a sound-emitting unit 13. The housing 11 has a receiving cavity 14. The sound-emitting unit 13 is disposed in the receiving cavity 14. The sound-transmitting cover 12 is disposed at the open end of the receiving cavity 14. The sound-emitting end of the sound-emitting unit 13 is aligned with the sound-transmitting cover 12. The sound-transmitting cover 12 is positioned from the front of the driver's cab to the rear. The sound emitted by the sound-emitting unit 13 is transmitted out through the sound-transmitting cover 12.

[0037] The light-emitting mechanism 2 includes a light guide strip 21 and a circuit board 22. The circuit board 22 is equipped with LED beads 25. The circuit board 22 supplies power to the LED beads 25. The LED beads 25 are connected to the end of the light guide strip 21. The LED beads 25 are used to emit light to illuminate the end of the light guide strip 21, so that the light guide strip 21 emits light. The light guide strip 21 passes through the housing 11 and is set against the inner side of the sound transmission cover 12. The light guide strip 21 is used to emit light, and the sound transmission cover 12 can also transmit light. The light emitted by the light guide strip 21 passes through the sound transmission cover 12 and into the driver's cab.

[0038] The light-emitting mechanism 2 includes a clamping plate 23, which has a first clamping strip 231, a second clamping strip 232 and a side plate 233. The first clamping strip 231 and the second clamping strip 232 are located at the upper and lower ends of the same side of the side plate 233, respectively. The first clamping strip 231 and the second clamping strip 232 together clamp the circuit board 22. The circuit board 22 is attached to the side plate 233 to prevent the circuit board 22 from falling off the clamping plate 23 when the vehicle is bumpy.

[0039] The first clamping bar 231 is provided with a first limiting bar 235, the second clamping bar 232 is provided with a second limiting bar 236, the first limiting bar 235 is provided with a first locking head 237, and the second limiting bar 236 is provided with a second locking head 238. The first limiting bar 235 and the second limiting bar 236 prevent the circuit board 22 from slipping, and the first locking head 237 and the second locking head 238 lock the circuit board 22 from the side.

[0040] The circuit board 22 is provided with a first bayonet 221 and a second bayonet 222. The first bayonet 221 is used to engage with the first limiting strip 235, and the second bayonet 222 is used to engage with the second limiting strip 236, further restricting the shaking of the circuit board 22 and preventing poor contact between the light guide strip 21 and the circuit board 22.

[0041] The light-emitting mechanism 2 also includes a guide body 24, which is connected to the clamping plate 23. A guide groove 240 is provided on the guide body 24, and a light guide strip 21 is laid in the guide groove 240 to prevent the light guide strip 21 from rubbing when the vehicle bumps and shakes. The end of the light guide strip 21 facing the lamp bead 25 is a smooth incident surface.

[0042] like Figure 4 and Figure 5 As shown, the sound transmission cover 12 is provided with multiple sound transmission holes 16. The sound transmission holes 16 are not only used for sound transmission, but also for transmitting light.

[0043] Multiple retaining strips 17 are provided on the inner side of the sound transmission cover 12. The multiple retaining strips 17 are bent and arranged on the same circumference. The light guide strip 21 is wrapped around the multiple retaining strips 17. The bent retaining strips 17 can prevent the light guide strip 21 from falling off.

[0044] like Figure 6 and Figure 7 and Figure 8 As shown, the speaker mechanism 1 also includes a light shield 18, which is disposed on the housing 11 and located above the sound transmission cover 12. The light shield 18 extends to the outer edge of the sound transmission cover 12, so that the light emitted from the sound transmission cover 12 cannot spread upwards and avoid shining on the driver's and passengers' glasses.

[0045] The speaker mechanism 1 includes a base frame 15, a housing 11 and a sound-generating unit 13 mounted on the base frame 15, and a light guide strip 21 passing through the gap between the housing 11 and the base frame 15 and then entering the receiving cavity 14.

[0046] The speaker mechanism 1 also includes a positioning plate 19, which has a recessed area 191. The base frame 15 is disposed in the recessed area 191, so that the base frame 15 and the housing 11 can reduce shaking.

[0047] The positioning plate 19 is used to fix it to the upper part of the vehicle dashboard, and the recessed area 191 has mounting holes 192.

[0048] The base frame 15 passes through the mounting hole 192. The positioning plate 19 is also provided with a first ring wall 193 and a second ring wall 194. The first ring wall 193 and the second ring wall 194 are located on both sides of the mounting hole 192. The first ring wall 193 has a first bottom wall 195, and the second ring wall 194 has a second bottom wall 196. The first bottom wall 195 and the second bottom wall 196 are arranged opposite to each other, and the first bottom wall 195 and the second bottom wall 196 together support the base frame 15.

[0049] The positioning plate 19 is also provided with an annular protrusion 197, which is high in the middle and low at both ends, and is arranged around the edge of the recessed area 191.
