The present invention provides a coaxial speaker including a frame, a magnetic circuit system, a first vibration system and a second vibration system fixed on different sides of the magnetic circuit system. The first vibration system locates communicated with the second vibration system. The first vibration system includes a first diaphragm and a first voice coil. The second vibration system includes a second diaphragm and a second voice coil. The magnetic circuit system includes a first magnetic gap and a second magnetic gap. The first voice coil partially locates into the first magnetic gap, the second voice coil partially locates into the second magnetic gap. The first diaphragm is used for generating bass sound, the second diaphragm is used for generating treble sound. A sound hole is provided on the first diaphragm for emitting the treble sound. Bass sound and treble sound form a full-range speaker, which providing high-quality sound.

A method includes: sending at least two sound wave signals through a loudspeaker; receiving, through a microphone, at least two sound wave signals from a second electronic device, and determining a first receiving result of receiving the at least two sound wave signals; determining a first possible angle value between the second electronic device and a first electronic device based on the first receiving result; and receiving a second possible angle value between the first electronic device and the second electronic device that is from the second electronic device, and determining an actual angle between the first electronic device and the second electronic device based on the first possible angle value and the second possible angle value; or sending the first possible angle value to the second electronic device, and receiving an actual angle between the first electronic device and the second electronic device.

A coaxial speaker box includes a housing, a speaker, and a sound guide channel for guiding sound outside. The speaker includes a frame, a magnetic circuit system, a first vibration system, and a second vibration system. The first vibration system is disposed in the frame. The second vibration system is disposed on an outer side of the frame. A front cavity is formed among the first vibration system, the second vibration system, and the housing. The first vibration system includes a first vibrating diaphragm and a first voice coil. A coaxial full-band speaker is formed by the bass and the high pitch of the coaxial speaker box to provide high-quality sound effects. The high pitch and the bass share a side sound guide channel, and form a front cavity resonance in a bass channel to improve high-frequency sound effects.

Coaxial speaker box

The present invention provides a coaxial speaker including a frame, a magnetic circuit system, a first vibration system fixed on an inner side of the frame, and a second vibration system fixed on an outer side of the frame. The first vibration system locates coaxially with the second vibration system. The first vibration system includes a first diaphragm and a first voice coil. The second vibration system includes a second diaphragm and a second voice coil. The magnetic circuit system includes a first magnetic gap and a second magnetic gap. The first voice coil at least partially locates into the first magnetic gap, the second voice coil at least partially locates into the second magnetic gap. The first diaphragm is used for generating treble sound, and the second diaphragm is used for generating bass sound. Bass sound and treble sound form a full-range speaker, providing high-quality sound.
