The utility model mainly relates to an earphone which comprises a shell assembly, the shell assembly comprises a first shell, the first shell comprises a first side wall part and a second side wall part which are opposite to each other and arranged at an interval, the earphone is further provided with a deformation part and a sensor, and the deformation part is arranged between the first side wall part and the second side wall part. The first side wall portion and / or the second side wall portion deform when bearing opposite extrusion force applied from the outer side in the interval direction of the first side wall portion and the second side wall portion and jointly extrude the deformation piece so that the deformation piece can be bent in the lateral direction of the interval direction, and the sensor is arranged in a bending area of the deformation piece. And when the bending degree of the bending area is greater than a preset bending threshold value, a corresponding electric signal is generated. Through the above mode, the touch precision of the earphone and the anti-interference capability of the touch function can be effectively improved, and through the above mode, the manufacturing cost of the earphone can be effectively reduced while the touch sensitivity of the earphone is effectively improved.

Display panel and display device
PendingCN122085554AImprove touch performanceAvoid the impact of transmission speedNon-linear opticsInput/output processes for data processingComputer hardwareDisplay device
This invention discloses a display panel and a display device. The display panel includes: a substrate; multiple touch electrode blocks disposed on one side of the substrate, with each touch electrode block spaced apart and insulated from the others; a first touch trace, a second touch trace, and an auxiliary trace, all disposed on one side of the substrate, with the auxiliary trace electrically connected to the first and second touch traces respectively, and each second touch trace electrically connected to its corresponding touch electrode block; and a driving circuit, with one end of the first touch trace electrically connected to the driving circuit, and the second touch trace not electrically connected to the driving circuit. This allows the driving signal to be directly transmitted from the first touch trace to the second touch trace via the auxiliary trace, without needing to pass through the touch electrode blocks, effectively avoiding the impact of the high impedance of the touch electrode blocks on the driving signal transmission speed, and improving the touch performance of the display panel.
