The invention relates to the field of loudspeaker quality detection, in particular to a method for testing the bonding strength of a voice diaphragm in a high-temperature environment, which comprises the following steps of: respectively positioning a bracket of the voice diaphragm and a framework of a voice coil, and moving into an environment of 180-185 DEG C; air of 185-190 DEG C is blown into the voice coil and the peripheral outer wall of the voice coil connected with the voice diaphragm; the positioned voice diaphragm and the positioned voice coil are continuously close to and far away from each other and are kept for 5-6 hours; the voice diaphragm and the voice coil which are tested are assembled into the loudspeaker to test whether the loudspeaker can be used normally or not, rapid temperature rise of the joint of the voice diaphragm and the voice coil is facilitated, the voice diaphragm and the voice coil are closer to an actual use environment in the whole detection process, and the accuracy of a det
