The invention discloses a vehicle horn abnormal sound diagnosis method, device and equipment and a readable storage medium, and relates to the technical field of vehicle diagnosis, and the method comprises the steps: obtaining target spectrum data corresponding to a target abnormal horn in a vehicle state and a target modal frequency corresponding to a target horn support in the vehicle state; performing spectrum analysis on the target spectrum data and the spectrum data corresponding to the target normal loudspeaker, and determining a target abnormal frequency corresponding to the target abnormal loudspeaker; and if a difference value between the target abnormal frequency and the target modal frequency is within a preset difference value range, determining that the target loudspeaker bracket is in an abnormal state, and taking the abnormal state of the target loudspeaker bracket as a reason for sound tone modification of the target abnormal loudspeaker. According to the invention, the sound tone modification of the whole vehicle horn caused by the abnormal state of the whole vehicle horn support can be effectively identified and diagnosed.

    一种整车喇叭异常声音诊断方法、装置、设备及可读存储介质,涉及汽车诊断技术领域,包括获取与处于整车状态下的目标异常喇叭对应的目标频谱数据以及与处于整车状态下的目标喇叭支架对应的目标模态频率;对所述目标频谱数据和与目标正常喇叭对应的频谱数据进行频谱分析,确定出与目标异常喇叭对应的目标异常频率;若所述目标异常频率与所述目标模态频率间的差值位于预设差值范围内,则判定所述目标喇叭支架处于异常状态,并将所述目标喇叭支架处于异常状态作为所述目标异常喇叭出现声音变调的原因。通过本申请,可以有效识别诊断出因整车喇叭支架处于异常状态而引发的整车喇叭声音变调。
