LG unveils vibrating speakers as an ultra-thin alternative to traditional car audio

LG Display today announced slim, vibrating car speakers for the first half of 2023. The slim driver sound solution has passport-sized dimensions and forgoes many bulkier parts than a typical car speaker.

The new tweeter does not use a cone, magnet, or voice coil and does not require a speaker grille. Instead, the speaker relies on what the company describes as “film-type excitation technology,” which vibrates display panels “and various materials inside the car body” to create a “3D” sound that LG Display claims is as good as what traditional car speakers produce.

LG even worked with a “global audio company” to develop the speakers, but we can’t tell you if that’s impressive or not because LG Display didn’t name a partner.

Excitation devices are compact, giving them the versatility of an operator’s sound-savvy solution when it comes to their placement and freeing up more space inside vehicles. LG Display sees the display being used in car dashboards, headrests, roof liners, and pillars, for example. The speaker measures 5.9 x 3.5 x 0.1 inches (150 x 90 x 2.5 mm) and weighs 1.4 ounces (40 g). In its announcement, LG Display said it was 10 percent as thick as a typical car speaker and 30 percent as heavy.
