The present disclosure relates to electronic devices, in particular to a multifunctional sounding device.
With developments of electronic technologies, portable electronic devices are becoming more and more popular, such as smart phones, handheld game players, palmtops, and so on. These electronic devices interact with users through emitting sounds and/or providing vibrations.
An electronic device in the related art has an individual speaker for emitting sounds and an individual vibrator for providing vibrations. Separate installations of the speaker and the vibrator cause a cumbersome manufacturing process. While, the speaker and the vibrator occupy a great many of interior spaces of the electronic device.
Thus, it is necessary to provide a novel multifunctional sounding device to solve the problem.
An objective of the present disclosure is to provide a multifunctional sounding device which combines functions of emitting sounds and providing vibrations. When installing the multifunctional sounding device into an electronic device, the multifunctional sounding device simplifies separate installations of an individual speaker and an individual vibrator and occupies fewer interior spaces of the electronic device.
In order to achieve the objective mentioned above, the present disclosure discloses a multifunctional sounding device including a frame, a vibrator assembly, and a speaker assembly. The vibrator assembly and the speaker assembly are accommodated in the frame. The vibrator assembly includes a vibrating unit suspended in the frame and vibrating along a first direction. The speaker assembly includes two magnetic units, a diaphragm, and two voice coils. The two magnetic units are fixed to the frame and locate on two opposite sides of the vibrating unit respectively. Each magnetic unit includes a magnetic gap. The diaphragm is fixed to the frame and vibrates along a second direction. The second direction is perpendicular to the first direction. The two voice coils locate in the magnetic gaps of the two magnetic units respectively and drive the diaphragm for vibrating and generating sounds. A winding axis of each voice coil is perpendicular to the first direction and the second direction.
Further, each magnetic unit includes two magnets spaced apart from each other for forming the magnetic gap and two pole plates attached to two surfaces of the two magnets away from the magnetic gap respectively.
Further, the vibrator assembly includes two elastic supporting members fixed to the frame and located at two opposite ends of the vibrating unit for suspending the vibrating unit in the frame.
Further, the vibrator assembly includes a driving coil fixed to the frame, the vibrating unit includes a weight and a magnetic system fixed to the weight, the magnetic system is opposite to and spaced apart from the driving coil.
Further, the vibrator assembly includes a stator fixed to the frame, the vibrating unit includes a weight with a receiving space and a magnetic system received in the receiving space, the stator locates in the receiving space and is opposite to and spaced apart from the magnetic system, the stator includes a magnetic core and a coil wound on the magnetic core.
Further, the frame is provided with two through holes for the two voice coils passing through respectively.
Further, the speaker assembly includes a skeleton for connecting the diaphragm and the two voice coils.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawing are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure.
The present disclosure will hereinafter be described in detail with reference to the embodiments. To make the technical problems to be solved, and technical solutions and beneficial effects of the present disclosure more apparent, the present disclosure is described in further detail together with the figures and the embodiments. It should be understood the embodiments described hereby are only to explain the disclosure, not intended to limit the disclosure.

The vibrator assembly 2 includes a vibrating unit 21 suspended in the frame 1 and vibrating along a first direction X, two elastic supporting members 22 fixed to the frame 1 (upper shell 12) and located at two opposite ends of the vibrating unit 21 for suspending the vibrating unit 21 in the frame 1, and a driving coil 23 fixed to the frame 1 (lower plate 11). The vibrating unit 21 includes a weight 211 and a magnetic system 212 fixed to the weight 211. The magnetic system 212 is opposite to and spaced apart from the driving coil 23. In other embodiments, some other supporting forms may replace the elastic supporting members 22 as long as the vibrating unit 21 can be suspended and vibrate in the frame 1, such as guide rails or guide shafts.
The speaker assembly 3 includes two magnetic units 31 fixed to the frame 1 (lower plate 11) and located on two opposite sides of the vibrating unit 21 respectively, a diaphragm 32 fixed to the frame 1 (upper shell 12) and vibrating along a second direction Y, and two voice coils 33 driving the diaphragm 32 for vibrating and generating sounds. The second direction Y is perpendicular to the first direction X. Each magnetic unit 31 includes a magnetic gap 310. The two voice coils 33 locate in the magnetic gaps 310 of the two magnetic units 31 respectively. A winding axis Z of each voice coil 33 is perpendicular to the first direction X and the second direction Y. Optionally, each magnetic unit 31 includes two magnets 311 spaced apart from each other for forming the magnetic gap 310 and two pole plates 312 attached to two surfaces of the two magnets 311 away from the magnetic gap 310 respectively.
Optionally, the speaker assembly 3 further includes a skeleton 34 for connecting the diaphragm 32 and the two voice coils 33. The skeleton 34 can couple dispersed driving forces generated by the two voice coils 33 in two positions for driving the diaphragm 32 synchronously and making the diaphragm 32 vibrating in balance.
The frame 1 (lower plate 11) is provided with two through holes 10 for the two voice coils 33 passing through respectively. The two through holes 10 can provide enough vibration spaces for the two voice coils 33, and also keep air pressures inside and outside the frame 1 in balance.
