Vibration testing device
A vibration testing device to test vibration strength and frequency generated by an electronic device, includes a base, a vibration contact member, a transmission member, and a resilient member attached to the transmission member. The base includes a receiving space to receive the electronic device and a receiving hole in communication with the receiving space. The transmission member extends through the receiving hole and is rigidly attached to the vibration contact member. During testing, the electronic device directly abuts an end portion of the transmission member so that the vibration strength and frequency generated by the electronic device are directly transmitted to the vibration contact member.
1. A vibration testing device to test vibration strength and frequency generated by an electronic device, the vibration testing device comprising:
a base comprising a receiving space to receive the electronic device and a receiving hole in communication with the receiving space;
a vibration contact member to obtain the vibration strength and frequency generated by the electronic device;
a transmission member extending through the receiving hole and rigidly attached to the vibration contact member; and
a resilient member connected between the base and the transmission member;
wherein during testing, the electronic device directly abuts an end portion of the transmission member, the transmission member moves along the receiving hole to enable the vibration contact member to move away the base synchronously, causing the resilient member to become compressed and the vibration contact member to be overhung, so that the vibration strength and frequency generated by the electronic device are directly transmitted to the vibration contact member.
2. The vibration testing device as recited in claim 1 , wherein the transmission member comprises a transmission shaft and a transmitting portion located at a first end of the transmission shaft.
3. The vibration testing device as recited in claim 2 , wherein the transmitting portion is a flange, wherein a diameter of the flange is greater than a diameter of the transmission shaft.
4. The vibration testing device as recited in claim 2 , wherein the transmitting portion is a pin extending through the first end of the transmission shaft, wherein a length of the pin is greater than a diameter of the transmission shaft.
5. The vibration testing device as recited in claim 2 , wherein the receiving hole comprises a locating hole, a through hole, and a step between the locating hole and the through hole, wherein a diameter of the locating hole is greater than a diameter of the through hole.
6. The vibration testing device as recited in claim 5 , wherein the resilient member is fixed between the transmitting portion of the transmission member and the step of the receiving hole.
7. The vibration testing device as recited in claim 6 , wherein the resilient member is a spring.
