DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] The present invention will be described from the following accompanying drawings, and the specific embodiments.
[0014] As shown in FIG. 1 to FIG. 5, an audio device according to a preferred embodiment of the present invention is illustrated, wherein the audio device comprises a casing 1, a handle frame 2 downwardly extended from a bottom side of the casing 1, a microphone cover 3 coupled at an upper side of the casing 1, a microphone 4 received in the microphone cover 3, a speaker assembly 5 and a PCB board 8 received in the casing 1. The microphone 4 and the speaker assembly 5 are electrically connected to the PCB board 8, wherein the microphone 4 is arranged for sound collection to transmit to the PCB board 8 while the speaker assembly 5 is arranged for sound play back from the PCB board 8. According to the preferred embodiment, the microphone 4 is supported on the casing in a dynamic manner to allow the microphone 4 being slightly moved with respect to the casing 1 for preventing a vibration of the casing 1 being directly transmitted to the microphone 4. In other words, the speaker assembly is able to instantly output a sound signal collected by the microphone through the PCB board 8.
[0015] According to the preferred embodiment, the microphone 4 as the dynamic microphone has an advantages of high impedance, good sound quality, and strong omni-directional ability, such that the electro-acoustic conversion effect and overall performance of the audio device of the present invention will be enhanced. Furthermore, the speaker assembly 5 is provided in the casing 1, wherein under the control of the PCB board 8, the sound can be played back by the speaker assembly 5 at the same time when the sound is collected by the microphone 4 so as to meet different requirements.
[0016] For a display purpose, the audio device further comprises a display unit 6 provided at a lateral side of the casing 1 and electrically connected to the PCB board 8. Preferably, the display unit 6 is a LED display unit incorporating with a LED indicating light. Alternatively, the display unit 6 can be a digital screen or the like.
[0017] In order to support the microphone 4, the audio device further comprises a microphone supporter 7 coupled at the casing 1, wherein the microphone supporter 7 is extended through the upper side of the casing 1. The microphone 4 is movably coupled to microphone supporter 7 so as to support the microphone 4 above the casing 1. Accordingly, the microphone supporter 7 is arranged for absorbing the vibration from the casing 1 to prevent the vibration directly transmitted to the microphone 4.
[0018] According to the preferred embodiment, the microphone supporter 7 comprises an outer supporting ring 70 coupled at the casing 1, an inner supporting ring 71 disposed within the outer supporting ring 70 to define a circumferential gap between the outer supporting ring and the inner supporting ring 71, and a plurality of ring connectors 72 spacedly disposed at the circumferential gap to retain the inner supporting ring 71 being encircled within the outer supporting ring 70. In other words, each of the ring connectors 72 is extended radially and has an inner end biased against an outer circumferential surface of the inner supporting ring 71 and an outer end biased against an inner circumferential surface of the outer supporting ring 70. Preferably, the inner supporting ring 71 is coaxially supported within the outer supporting ring 70 via the ring connectors 72. Accordingly, at least one of the outer supporting ring 70, the inner supporting ring 71 and the ring connectors 72 is made of shock absorbing material such as soft rubber material. In one example, the ring connectors 72 re made of shock absorbing material. For example, the outer supporting ring 70, the inner supporting ring 71 and the ring connectors 72 are individual components, wherein only the ring connectors 72 are made of shock absorbing material such as soft rubber material. Preferably, the outer supporting ring 70, the inner supporting ring 71 and the ring connectors 72 are integrally formed to form a one piece integrated member which is made of shock absorbing material such as soft rubber material. In other words, by dynamically connecting the microphone 4 to the microphone supporter 7, the microphone supporter 7 is made of shock absorbing material that allows a slightly movement of the microphone 4 with respect to the casing 1 by means of dynamic connection and absorbs the vibration from the casing 1.
[0019] Accordingly, the outer supporting ring 70 and the inner supporting ring 71 are spaced apart with each other and the ring connectors 72 are formed in the circumferential gap between the outer supporting ring 70 and the inner supporting ring 71 to form the one piece integrated member. Since the microphone supporter 7 is made of shock absorbing material, the microphone supporter 7 provides a buffering function to absorb and/or cancel the vibration and/or impact at the casing 1, so as to ensure the excellent electro-acoustic conversion performance of the microphone 4.
[0020] For facilitating the installation of the microphone 4, a height of the inner supporting ring 71 is larger than a height of the outer supporting ring 70, wherein a top end of the inner supporting ring 71 is protruded above the outer supporting ring 70 to couple with the microphone 4.
[0021] Furthermore, the microphone supporter 7 further has at least a wire extending slot 73 formed at the inner supporting ring 71 for a connecting wire extending therethrough to connect to the microphone 4. Preferably two wire extending slots 73 are provided at two sides of the inner supporting ring 71 that two connecting wires are guided to extend through the wire extending slots 73 at the inner supporting ring 71 to connect to the microphone 4.
[0022] For facilitating the wire storage, sorting, and leading out, in this embodiment, the microphone supporter 7 further has a receiving indentation 74 formed at a bottom side of the inner supporting ring 71 to communicate with the wire extending slot 73. Therefore, an excessive portion of the connecting wire at the bottom side of the inner supporting ring 71 can be organized and received at the receiving indentation 74.
[0023] According to the preferred embodiment, the speaker assembly 5 comprises a speaker 50 electrically connected to the PCB board 8.
[0024] Furthermore, the speaker assembly 5 further comprises a diaphragm support 51 coupled at a back side of the speaker 50, and a passive diaphragm film 52 coupled at the diaphragm support 51 for outputting the sound signal. Via the action of the passive diaphragm film 52, the sound output of the speaker assembly is greatly improved, so as to highly enhance the sound quality of the audio device of the present invention.
