Description

Electronic device Technical Field The present invention relates to a device, and more particularly, to an electronic device. Background At present, based on the design requirement of the electronic device, the sensor and the pressurizing assembly are often integrated together, so that the sensor may be impacted when the pressurizing assembly vibrates, and the sensor is damaged. It is therefore a challenge to avoid the occurrence of impact on the sensor when the pressurizing assembly vibrates. Disclosure of Invention Accordingly, in view of the above-mentioned problems, it is desirable to provide an electronic device that can prevent the sensor from being damaged due to the sensor being impacted by excessive vibration of the pressurizing assembly when the pressurizing assembly is subjected to an external strong impact, and the electronic device cannot operate. The invention discloses an electronic device, which comprises a substrate, a sensor, a partition wall structure, a pressurizing assembly and a blocking structure. The substrate is provided with a bearing surface. The sensor is arranged on the bearing surface. The partition structure is arranged on the bearing surface and surrounds the sensor. The pressurizing assembly is arranged on the partition wall structure. The pressurizing assembly, the partition wall structure and the base plate jointly form a cavity, and the pressurizing assembly comprises a mass block and a vibrating diaphragm. The blocking structure is arranged between the pressurizing assembly and the partition wall structure and extends into the chamber. The blocking structure is provided with at least one opening penetrating through the blocking structure. In one embodiment, the blocking structure is disposed between the pressurizing assembly and the sensor, and forms at least one distance with each of the pressurizing assembly and the sensor. In one embodiment, the shortest distance between the blocking structure and the pressurizing assembly is smaller than the shortest distance between the blocking structure and the sensor. In one embodiment, the mass and the at least one opening are rectangular in shape. In one embodiment, the at least one opening has a length greater than a length of the mass. In one embodiment, the partition structure is of a different material than the blocking structure, and the blocking structure is sandwiched between the partition structure and the pressurizing assembly. In one embodiment, the material of the partition wall structure is the same as that of the blocking structure, and the partition wall structure and the blocking structure are integrally formed. In one embodiment, the at least one pair of openings is located in the mass. In one embodiment, the mass, the at least one opening, and the sensor at least partially overlap. In one embodiment, the width of the at least one opening is smaller than the width of the mass. In one embodiment, the blocking structure includes a protrusion extending toward the diaphragm and a support connected to the protrusion. In one embodiment, the anti-sticking protrusion is located opposite to the diaphragm. In one embodiment, the anti-sticking protrusion is disposed around the periphery of the support portion and along the periphery of the at least one opening. In one embodiment, the at least one opening is a plurality of openings. In one embodiment, the electronic device further comprises a tuning layer disposed on a surface of the blocking structure adjacent to the sensor. In one embodiment, the tuning layer is disposed corresponding to the at least one opening. Based on the above, the electronic device of the present invention is characterized in that the blocking structure is disposed between the pressurizing assembly and the partition wall structure and extends into the chamber with the sensor by introducing the blocking structure, so that the blocking structure can limit the over-displacement of the pressurizing assembly, and the existence of the blocking structure does not affect the air conduction of the electronic device to the sensor because the blocking structure has at least one opening penetrating the blocking structure, so that the electronic device of the present invention can not only regulate the product performance by the structure of the present invention, but also avoid the sensor damage caused by the sensor being bumped when the pressurizing assembly excessively vibrates when being impacted by external strong force, and the electronic device cannot operate.
