Portable communication device

Abstract

The invention discloses a portable communication device which is provided with holding space, a first housing and a second housing. The first housing and the second housing form the holding space. The holding space is home to a PCB, a MIC and a horn BOX. The second housing is provided with a through hole. The sealing structure of the MIC includes a support that extends from the horn BOX towards the through hole. The support and the PCB are sealed through a first sealing body. The end of the support far from the horn BOX nears the through hole and is sealed to the second housing wall through a second sealing body. The support is provided with a channel that is communicable with the through hole; the channel port far from the through hole is communicated with the MIC so as to allow external sound sources to be transmitted to the MIC from the through hole and the channel.

Description

technical field [0001] The invention relates to a portable communication device, in particular to a portable communication device which utilizes a speaker BOX support structure to seal a MIC. Background technique [0002] Portable communication devices (such as smart phones, tablet computers, etc.) are inseparable from people's lives, and their various designs directly affect user experience to some extent. In existing portable communication devices, the structure in which the battery cover covers the first casing is the current mainstream design. However, this structure all faces a thorny problem, that is, the airtightness of the main MIC. Generally speaking, the main MIC mainly collects the sound outside the product through the connected MIC holes respectively opened on the battery cover and the second casing. However, in the existing structure, the battery cover and the second casing of some devices cannot It fits perfectly, so that there is inevitably a gap between the...

Problems solved by technology

However, since the silicone sleeve is tightly attached to the MIC and has multiple sealing surfaces, when the portable communication device accidentally falls or collides with other objects, the battery cover will transmit the impact force to the silicone sleeve, thereby reducing the impact. The force is directly transmitted to the MIC through multiple sealing contact surfaces that are close to the MIC, causing impact damage to the MIC, resulting in desoldering, and then causing the MIC function to fail

Furthermore, since there are too many sealing surfaces between the silicone sleeve and the MIC components, no matter in which direction the silicone sleeve is squeezed, there will be a gap on the opposite side.

Therefore, the more mating surfaces between the silicone sleeve and the MIC, the greater the probability of sound leakage, and it is difficult to guarantee its tightness.
